• Least CPU intensive way of streaming your screen on windows?

  - by sinni800

  Hello, sometimes I like capturing my screen for others to see. Only thing: I am playing games while I do it. I have tried a few streaming solutions where Windows Media Encoder coupled with my own Windows server appealed to me most, because I can change resolutions, etc. I also tried ustream coupled with the Flash applet and the Adobe Flash Encoder recording a Camtasia source. Camtasia has the disadvantage though that it shows the green-and-black-alternating borders and can not be targeted fullscreen. I like how xfire does it. But it doesn't work with every game, many are simply not supported. A few thoughts about this: Is there a program which captures like Fraps or XFire (based on Direct3D and OpenGL outputs) and exposes the output to a DirectShow source filter? Which brings me to: Is there hardware accelerated capturing directly from the graphics card? Maybe including direct encoding with help from OpenCL? Modern graphic cards decode BluRay content directly for example. I should have a modern enough graphics processor for this to be possible (see below). If using Windows Media Encoder: Which are the least CPU intensive settings? Which codec? Is there a newer codec than Windows Media 9? Is it less CPU intensive? I only have 7, 8 and 9 inside the Encoder Could the performance be massively increased by having a Quad-Core CPU (see below)? Bandwidth is no problem up to 1000 to 1500 kbit/s (I have 2048). My Computer specs: Intel Core 2 Duo E8400 4 GB DDR2-800 Ram Ati Radeon HD5770 Using Windows 7 Professional

• Macbook Pro won't boot from DVD with SSD

  - by Adam Carr

  Here's the timeline of events. Had a running MBP 17 Early 2011 Thunderbolt with OWC Mercury Extreme Pro SSD 115GB drive. Installed Windows 7 via bootcamp. I have done this multiple times before and every time I need to format the bootcamp partition before installing. I think this time I actually deleted the partition and then selected the freespace to install. This worked fine for the most part but I wasn't able to boot the boot camp partition using vmware fusion. I gave up and used the boot camp assistant to revert back to one mac partition. I was getting some odd behavior so I rebooted the machine. It then came up with a message saying no bootable partiton. This made me think (and still does) that the windows install using the free space versus the boot camp partition caused the windows MBR boot loader to get installed incorrectly and mucked up the OS X installation. Ok, fine, I can just reinstall. I can't seem to boot from the original MBP installation DVD. I hold down c on boot but I never get past the all grey screen. I hear the DVD drive spin up but it eventually stops. I put the original HD back in it and everything works fine but when I put the SSD in, I can't boot from the DVD drive. I have already set up an RMA with OWC to send back the drive but considering the order of events, I feel as though it isn't a hardware issue but can't seem to figure out how to fix it. I can always send it back in but figured I would check and see if anyone could offer some guideance/assistence before doing so.

• Huge host CPU usage in idle vmware guest. Ubuntu 10.04 host, Vista SP2 guest

  - by themesandmodules

  I'm experiencing huge host CPU usage with an idle vmware guest. Host: Ubuntu 10.04 32-bit 2.6.32-24-generic-pae. (Very new install, i.e 24 hours ago) Hardware is Dell XPS M1530 laptop, 4GB ram. Intel Core II Duo T9300 2.50Ghz The virtualization setting "VT" or something is enabled in my bios. Guest: Completely fresh install of Windows Vista, upgraded to latest SP2 and all windows updates installed. 1024 - 1512MB ram allocated. Absolutely no other software installed on it, apart from VMWare tools. Situation When the guest is doing absolutely nothing, I watch with sysinternals process watch on the guest. This shows that system idle process is between 70 and 99%, usually around 95%. No actual process doing anything. On the host, I watch with top, I get cpu usage of 20% - 80%, usually around 30%. What I have tried Single and Dual processor available to guest - no change. Turn off all peripherals to guest - no network, drives, usb etc - no change. Turn off 3d acceleration for guest - perhaps a small improvement, or no change. Upping allocated ram to guest from 1024MB to 1512MB - no change. Yelling at vmware - no change. I have experienced a similar issue in the past, which was solved by setting the guest to have 1 CPU. This time that hasn't worked.

• Cisco Multi-DMZ firewall

  - by BParker

  I need to find a firewall that will give me 1 LAN port, and 5-7 DMZ ports. I have a requirement to replace some FreeBSD systems that are used to run some testing equipment. It is essential that the DMZ ports cannot communicate with each other, but the LAN port can communicate with everyone. That way a user on the LAN can connect to the test systems, but the test systems are isolated entirely and cannot interfere with each other. One of the DMZ's will be connected to a VMWare ESXi server, one to a standard server, and the rest to various types of equipment. The lan port will be connected to the corporate LAN switch. Sorry if i am a little vague, I am just trying to work all this out myself! Currently we have a FreeBSD configured, but the quad port NIC's are pretty expensive, and the PC itself is old, so i would prefer to replace it with a dedicate piece of kit which can do the same job, but more reliably! These test rigs are used all over the place, and get moved quite often, so i am aiming for Cisco kit for ease of configuration and reliability of the hardware itself. Thanks

• Request bursting from web application Load Tests

  - by MaseBase

  I'm migrating our web and database hosting to a new environment on all new machines. I've recently performed a Load Test using WAPT to generate load from multiple distributed clients. The server has plenty of room to handle the traffic load, but I'm seeing an odd pattern of incoming traffic during the load tests. Here is the gist of our setup: Firewall server running MS Forefront TMG 2010 on Win 2k8 server Request routing done by IIS Application Request Routing on firewall machine Web server is a Hyper-V VM on the Database server (which is the host OS) These machines are hefty with dual-CPU's with six cores (12 total procs) Web server running IIS 7.5 Web applications built in ASP.NET 2.0, with 1 ISAPI filter (Url Rewrite) in front What I'm seeing during the load tests is that the requests all come through in bursts. Even though I have 7 different distributed clients sending traffic loads, the requests come through about 300-500 requests at a time. The performance monitor shows nearly all of the counters moving through this pattern, where a burst of requests comes in the req/sec jumps to 70, the queued requests jumps to 500, the current requests jumps up, the CPU jumps up, everything. Then once it's handled that group of requests, it has a lull for nearly 10 seconds where nearly nothing is happening. 0-5 req/sec, 0 queued requests, minimal CPU usage. Then after 10 seconds of inactivity, another burst comes through, spiking all of the counters once again. What I can't figure out is why the requests are coming through in bursts when I know that the load being generated is not sent that way, especially considering the various load-generating clients sending traffic all in different intervals with random think time's between each request. Is there something in the layers between Hyper-V or perhaps in the hardware which might cause this coalesce of requests together? Here is what i'm looking at, the highlighted metric is Requests/sec, but the others critical counter go with it: Requests Queued (which I'd obviously like to keep as close to 0 as possible). Any ideas on this?

• Body of email breaks distribution list in exchange?

  - by widgisoft

  Hi, I have a very odd problem that I'm not sure is a programming issue or a server issue :-p. Basically I'm sending an email to an exchange distribution list that includes a PHP stack trace; during certain faults the trace includes really high level information such as the machine's environment variables (during file reads, etc.). I went through a copy of the email line by line until the email sent and it appears the line: [SUDO_COMMAND] => /etc/init.d/httpd restart is the culprit. Adding a string replacement in before the email is sent allows a successful send. What I don't understand is WHY these stream of characters are causing the issue ONLY on the distribution email. If I send the email to myself as well, i.e. "[email protected]; [email protected]", then I get the email fine. Re-ordering the list doesn't make a difference the group never gets the email. Because the individual gets the email and not the group I'm assuming the fault is with exchange and some rogue filtering - I've gone through it with the sysadmins and there's no filtering of any sort on that group... so maybe it's a bug? I can't find anyone else having recorded this specific fault so I figured I'd open it here. For now I'm just not using the distribution list but it'd be nice to eventually find the solution. Many thanks, Chris

• How to make a huge ram drive?

  - by Brandon Moore

  At my old job when a report was needed I could sit down with someone and pull up results and get immediate feedback, and then refine my queries and ultimately have the data we needed, in the format we needed within 30-90 minutes. I just started working for a new company with a database containing millions of records and I spent my whole 8 hours making a report that I feel I could have made in less than 2 hours if it were not for the massive amount of data the queries are working with, and the fact that I couldn't ask the person needing the data to sit down with me and give me feedback as I pulled up results as I am used to. So I am trying to think of how we can make the server faster... much faster, so that I can have the same level of productivity I'm used to. One thought that just came to mind is that memory is so cheap these days, and by my calculations I could buy 10 8gig ram sticks for 1000 bucks. What I have never heard of though is a device that would let me combine these into a huge ram drive. So I'd like to know if any such device exists, and if not what is the largest ram drive I could realistically make and how would I go about doing so? EDIT: To you guys who are saying the database shema needs to be analyzed... you can't make a query such as "Select f1, f2, f3, etc from SomeTable" run any faster by normalizing or indexing the table. What I'm talking about IS ABSOLUTELY a need for improved performance at the hardware level. I am used to having results come back to me in a few seconds, not a few minutes or much less a half an hour. Maybe that's what you guys are used to who have 100 billion record tables and you feel like that's fast, but I'm looking for results back from tables with about 10 million records to come back to me withing less than half a minute TOPS.

• Software to capture 3d geometry?

  - by user712092

  Programs I found I found these programs to capture OpenGL 3D scene : 3D Ripper, OpenGL and D3D geometry capture, there are some solved problems with 3D Ripper GLIntercept captures OpenGL function calls OpenGL Extractor captures 3d geometry; should work as plugin for GLIntercept another tool to capture OpenGL 3D data EDIT: There is also HijackGL which changes how a scene is rendered so it probably can be used to capture geometry; it is backed up by a academic paper; it is just just a nice program, not related to what I want i think (or it would might be hard to change it to be for what I want, because it would require programming). 3D Ripper captures geometry, textures and shaders. OpenGL Extractor captures just geometry ... General questions about such programs What is Your experience with these programs? Which of these programs would You recommmend? Do You know other such programs? Were there any problems with them, or are there problems with them in general? Are there programs which work best overall, or is it specific to certain 3d applications? What I need to do? I am looking to program which can capture 3d geometry for study purposes. And also for a program to capture 3D animation (frames of 3d animation). I tried only 3D Ripper because application I try to capture data from is on Direct 3D. 3D Ripper works with at least Direct 3D 9, this application has Direct 3D 6. Are there applications which work with older version of Direct 3D? Thank You very much. :) (I was verbose in link names because I want them to be indexed better by search engines.)

• SQL Server Installation: Is it 32 or 64 bit?

  - by CapBBeard

  Recently I was performing an OS upgrade on one of our DB servers, moving from Server 2003 to Server 2008. The DBMS is SQL Server 2005. While reinstalling SQL on the new Windows installation, I went to another of our DB servers to verify a couple of settings. Now, I always thought this second server was Server 2003 x64 + SQL 2005 x64 (from what I'd been told), but I now have my doubts about this. I now suspect that it is in fact only 32 bit SQL, however I'd like to verify this. Here's some details: The OS is definitely 64 bit. xp_msver shows Platform as NT INTEL X86 SELECT @@VERSION shows Microsoft SQL Server 2005 - 9.00.4035.00 (Intel X86)... However sqlservr.exe is not shown with '* 32' in taskmgr, does anyone know why this is the case, if it is in fact 32 bit as claimed? Despite this, it does seem to be running out of the x86 program files folder. If I do the same checks on a confirmed 64 bit installation, it does give back the expected 64 bit readings, which can only prove that this server in question is only running in 32 bit. Now, that being the case, the question arises about how much memory this '32 bit' install can use. Task manager reports about 3.5GB memory usage for sqlservr.exe (The server has 16GB physical). I suspect that AWE has not been configured at all, and therefore the server will be significantly under-utilised (remembering that the OS is 64 bit) if SQL is simply using a 32bit address space. Is this assumption correct? I feel the server should have SQL reinstalled as 64 bit in order to fully utilise the hardware platform, however it is currently heavily in production; this will be no easy task. I suspect we may just have to configure AWE correctly and let it be for the time being (Unless this is a bad idea?). I apologise that this question is a little vague/lost; I'm no SQL expert, just trying to get a handle on what's going on here.

• Virtual (ESXi4) Win 2k8 R2 server hangs when adding role(s)

  - by Holocryptic

  I'm trying to provision a 2k8r2 Enterprise server in ESXi4. The OS installation goes fine, VMware tools, adding to domain, updates. All the basic stuff before you start adding Roles and Features. I've had this happen on two attempts already, and I'm not sure where the problem might be. I don't think it's hardware, because I have another 2k8r2 Standard server that's running fine. The only real difference is the install media. The server that's working was installed using a trial ISO and license. The one I'm having problems with is a full MAK installation. When I go to add a Role (the last case was Application Server) it gets all the way to "collecting installation results" before it hangs. CPU utilization in the vSphere client shows little spikes of activity with flatlines inbetween, but the whole console is locked up. The only way to release it is to power off and bring it back up. When you go to look at the added roles after bringing it back up, it shows that it is installed, but I don't trust that something didn't get wedged in all of that. The first install I did was with Thin Disk provisioning. The second attempt was with regular disk provisioning. In both cases 4GB of RAM, 2 vCPUs. VMware host is a HP Proliant DL380 G6, RAID-1 OS, RAID-5 data volume. 12 GB RAM. Has anyone else had this problem, or know where I should start poking around?

• BIOS corrupted? How to proceed? Acer Travelmate 290

  - by dtlussier

  I have a older ACER Travelmate 290 (manufactured in 2002 or 2003), which I recently tried to upgrade to Ubuntu 9.10. After doing the upgrade process it appeared as if I had a problem with my x server configuration, as on the first reboot post-install I heard the Ubuntu startup sound, but had a black screen. I thought I would then reboot again to drop down into text-mode to trouble shoot the x configuration problem. However, when I tried rebooting, something went wrong and since then when I start up the machine I get absolutely nothing except the first hardware check (i.e. HDD light flashes, CD/DVD drive spins, etc.). Other than that the screen remains totally black and I have no HDD or processor activity at all. I have tried restarting it a number of time holding down all kinds of key combinations to try and coax it into the BIOS (if possible) with no luck. I have also tried putting in both a live Linux disc and a Windows install disk without any luck. With a disk in the drive it will spin for a few seconds and then stop. All this has lead me to suspect that the BIOS is somehow corrupt (not sure about the right terminology). I have tried putting a new BIOS image and installer program downloaded from ACER on a USB key to see if it will run when I start up the machine, but no luck. I'm not sure if this method of interacting/updating/flashing the BIOS will work outside of Windows/DOS as both OSs are mentioned kind of ambiguously in the documentation. I have also taken the laptop case apart and inspected the various cards and cannot find any obviously burned out components. I'm not sure how to proceed at this point in terms of components to try, or how to try and load a new BIOS image onto the board. Any advice here would be great, especially from those with experience with this particular line of laptops. Thanks!

• Windows Server 2003 SBS domain in multiple sites

  - by E3 Group

  We have about 25 employees in our current office and are looking to open up another office in another capital city housing about 15 employees. In our current office, we are running a domain hosted by a 2003 SBS server and I've been tasked by the boss to expand our infrastructure to the new office in the cheapest way possible (cheapest way in the short run that is, because my boss doesn't think more than 6 months ahead). So I'm looking to get a second hand server and have it run Server 2003 Std with exchange server 2003. These are the things that it needs to do: Replicate shared folders that are hosted in the parent LAN. Deliver emails hosted in the parent Exchange Server Somehow link up with the parent domain controller and push the AD to the remote site I'm pretty sure 3 is impossible but the DC would be available if a VPN connection is present, right? On that note, would I be looking at hardware VPN connections? I'm not sure how to deploy the new site as this is my first time doing it and i'm making it especially difficult for myself, seeing as the AD and DC is on an SBS server. Would I first start by establishing a VPN connection and then joining the new server to the domain? Will things 'just work' if I install exchange onto the new server and point outlooks to it? and how would I be able to replicate shared folders?

• Which Linux distribution for vehicle LCD instrument panel

  - by Brent

  I will be designing an instrument panel for a vehicle to display the common gauges that you would find in a car - (speedometer, rpm, fuel level, oil pressure, etc.). We have selected a 7" LCD and are in the process of narrowing down the hardware (This will use an ARM processor). The idea is to read these values off of the CAN Bus and update the UI with those values. This needs to have a fairly quick boot time, 5-10 seconds would be acceptable from the time the ignigtion is turned on to the time the UI is running. I have been doing a lot of research on which linux distribution to use, but I wanted to ask the question here to get the community's suggestions. I have been a .NET programmer for years, so linux is a new world to me. Here is what I have found so far... Tizen is geared for In-Vehicle Infotainment (IVI) (plus some others). However, this project is not an IVI, and I do not need the phone dialer, navigation, etc. Meego is dead, and Tizen seems to be the replacement Angstrom, Debian... would either of these be useful? I am not tied to a particular programming language or IDE. Any help and direction is appreciated!

• New router messed up server 2003 setup...

  - by Aceth

  Hey, We were sent a new 2wire router today configured it as best we can to match the old bt voyager. We've also got X static IP's. We've manage to get our webserver on one of the new IP's public facing. then we use a hardware firewall which is in a DMZ again with a different static IP. This firewall then is our gateway for our internal LAN. with a few servers etc. The problem we're having is only our PDC (primary Domain controller which has exchange 2003 on) can't ping externally even an external IP. We've connected laptops to the 2wire router and obtain a private ip 192.168.1.X and it works fine can ping etc. our other servers with an internal ip behind the firewall can ping out fine. We've connected to the firewalls logging console and the pings from the server are allowed through so its fine there. The server in question is a Windows server 2003 R2 Enterprise SP2 + Exchange 2003 Server doesn't have firewall turned on. it has static private IP .. gateway is pointing to the right one External Static IP is routing fine inwards We've ran out of ideas .. help??

• Migrate Domain from Server 2008 R2 to Small Business Server 2011

  - by josecortesp

  I'm looking for some advice here, rather than the big how to do it I'm looking for what do to I have this home server, quad core and 4 GB of ram (I really can't afford more right now). With a Windows Serve 2008 R2 With ActiveDirectory and a Hyper-V-Virtual machine with SharePoint, TFS and a couple of more thigs. I have a least 10 remote users, all of them joined a Hamachi VPN (working great by the way). But I want to migrate that to a Small Business Server 2011 Standard. I tried to make a VM to join the domain and then promote that VM, back up it and then format the physical server, boot up the VM, Promote the Phisical and then erase the VM, but I can't do that because of SBS requiring a least 4 GB of ram to install (so I can't give all the 4 GB of physical ram to a VM). I was thinking in using a laptop (All the clients are laptop) as a temporal server, join the domain, promote it, then format the server and install SBS on the server and do all again. I really need some advice. Thanks in advance. BTW, I know that the software I'm using is kindda expensive, and I can't afford more hardware. I have access to MS downloads by a University partnership so I have all this software for free.

• CSV engine on MySQL server

  - by Jeff

  I don't think that this is a programming question so I am going to ask it here - Reading the book high performance mysql, I read about the CSV engine. The paragraph says: The CSV engine can treat comma-separated values (CSV) files as table, but it does not support indexes on them. This engine lets you copy files in and out of the database while the server is running. If you export a CSV file from a spreadsheet and save it in the MySQL server's data directory, the server can read it immediately. Similary, if you write data to a CSV table, an external program can read it right away. CSV tables are especially useful as a data interchange format and for certain kinds of logging. What I get from this paragraph is that I can copy a .CSV file into the data directory of database, and it should show as a table that is able to be read from. However, whenever I copy a test .csv file into the directory, it does not appear as a table. I can't access it. I am using MySQL 5.5 also Does anyone know why this is not working, or what I am doing wrong? Thanks

• How to get a higher resolution on Ubuntu 11.04 using an intel chipset

  - by Saif Bechan

  I have a bit slow PC here, so I decided to put Ubuntu 11.04 on it. It use to run Windows Vista on a resolution of 1280x1024, so both my hardware and monitor support it. Now I'm on Ubuntu, but can only run 1024x768, and the screen is not that bright. Its like when you don't have the right drivers on a Windows machine.

• Audio card with built-in ground isolator?

  - by Dave Jarvis

  What audio cards would you recommend that eliminate hum, and hard-drive & mouse movement signal interference? Hardware components: Motherboard. Asus P5Q SE Audio. Realtek ALC 1200, 8-Channel High-Definition Audio CODEC (on board) Harddrive. WD Caviar 320 GB Mouse. Logitech Marbleman USB Mixer. Mackie d.4 Pro Amplifier. Sonance Sonamp 260 All components are plugged into the same Monster Power HDP 910 powerbar (does not help eliminate noise). I have no other components plugged in. The computer uses a Monster iCable 1000 to go from mini (on board audio) to RCA (mixer). I have moved the cable as far from other cables as possible. A ground loop isolator between the mixer and on board audio eliminates all noise. I would rather not use a ground loop isolator; an internal audio card that is Linux-compatible (Kubuntu) would be ideal. Suggestions?

• Dropped connections between Linux Servers in Data Center

  - by Emil H

  I have a number of linux servers at a us-based datacenter. The servers were installed by the hosting company, and are running fedora core. We're experiencing problems with dropped connections. The issue seems to be that when we attempt to connect to one of the other servers after a period of inactivity, the first connection attempt will fail, and sometimes the second. However, after that the connection succeds and it works for a while. This happens for both mysql connections and raw socket connections, but only seems to occur when connecting to some of our servers. The confusing part is that it some of the servers for which we see different behaviors have identical hardware configuration and software. For example, it happens when connecting to a server called mysql2, but not for a server called mysql3. These servers were installed at the same time, but the same specifications. The problem can be reproduced somewhat reliably, but only after waiting fifteen minutes to half an hour. This makes it hard to diagnose, and even harder since I'm not really sure what to look for. I realize that connections sometimes failed, and that we should write our applications to compensate for this but these servers all in the same data center. Why would it matter if two servers haven't communicated for a while? Does anybody have an idea what might be causing this? Is it a server configuration problem or a network problem that I should contact the hosting company about. What do I tell them to look for? Unfortunately our experience has been that the support staff doesn't investigate problems in depth unless we give them detailed directions.

• Streaming to PS3 with NAS and built-in dlna server?

  - by philt

  With consumer-grade hardware, is it possible to successfully stream 1080p mp4 videos to a PS3? I have a linksys router that can only do 10/100. The PS3 is wired to it with cat5e cable, and the PS3 itself supports gigabit ethernet. I would upgrade the router and get one that supports gigabit ethernet if it could handle streaming like this. It currently does work with minor jerkiness streaming from my mac to the PS3, but fast-forward/reverse and "goto" (equivalent of scene selection) take forever and/or fail completely. And streaming from my mac of course requires the mac to be on at all times. When I put the movies on an external USB drive and connect to the PS3 directly, it performs flawlessly. Fast forward and everything works great. So I was thinking about getting a NAS, but I don't know if any inexpensive NAS (i.e. Buffalo Linkstation Live, WD My Book World Edition, D-Link DNS-321, etc.) can actually deliver the performance necessary to do this, even with gigabit ethernet?

• How expensive to run PC 24/7 or how to figure out how to determine it?

  I realize this question is difficult to answer as it would be different based on users location, what there PC is doing and what hardware it consist of, along with other factors but I am hoping someone could give me a very rough estimate. I have always ran many PC's in my home 24/7 and I am just now looking at it from a money/cost of electric point of view. 1) I live in Central Florida. Can anyone guesstomate/estimate the avaerage monthly or daily cost of running your average PC? Intel quad core processor, 1 SSD drive for OS and programs and 4-5 1-2 TB hard drives in a RAID setup for data. 750watt PSU. What would your guess be? 2) Also is there an accurate way to figure this out (non-super technical and confusing to a non-math person please) Also I have seen those kill-a-watt devices, do they figure this kind of stuff out for you? 3) Does a larger PSU make your PC consume more power? Thanks for any help, you can most likely tell I am somewhat lost about this!

• Seeking web-based FTP client for very large file upload

  - by Paul M. Nguyen

  I have looked around for these for some time... the limits imposed by the web server and/or the dynamic programming environment (e.g. PHP) are far too restrictive for the application I'm working on. We need to be able to move large graphics and video files to and from clients (ranging from tens of MB to a few GB in a single file). Plain FTP with a proper desktop client will do the trick, and we're hosting this in Amazon EC2 with EBS. User management will be done from the office via webmin. Users are chroot-jailed into their home dir by proftpd. net2ftp will work for many clients, but we often need to move single files that approach 1GB or exceed 2-3GB which is way out of the range of any http-based uploader. So we turn to Java or Flash - can they do it? From within the web browser establish an FTP connection and grab a huge file? There are licensed applets and such out there, but none seem convincing. Again, I'm looking for some code that can speak FTP and read (& write?) the local disk, that is delivered in a web browser, and can move single files of 2GB+. The reason for having a web-based interface to FTP is to skip the software installation step for our clients. I will consider proper desktop client software as long as it's "portable" and at least Win+Mac and can be easily configured by lay-man users in a hurry.

• How do I configure nVidia drivers on a Portable Ubuntu setup?

  - by Nicholas Flynt

  I've been pulling my hair out over this one for a couple of days now, google is no help. I've created a wonderful (until this issue) portable copy of Ubuntu linux that will boot on mostly anything by using a USB enclosure for my laptop's 80GB SATA drive. So far so good, it boots and runs on everything, and on non-nVidia card setups was even detecting the drivers, or letting me install the required drivers for hardware acceleration and compiz. Because you know, the wobble windows are the most awesome thing ever. Anyway, my desktop machine had an nVidia card, so I'm thinking, sure, I'll just install the nVidia drivers like before and everything will work happily. Not so-- now the desktop and any other nVidia cards work great, but it seems to have completely disabled any other graphics cards. When the kernel module detects that an nVidia card isn't present, it shoots up this nasty little dialog box giving me the option to boot into "low graphics" mode, which doesn't even allow me to use the correct screen resolution, much less see the installed graphics card and try to configure a driver for it. Is there any way to configure Ubuntu (with the dreaded nVidia kernel module) so that it can use nVidia's drivers when an nVidia card is present, and default to the normal (not low-graphics) setup in other cases, so that it has a fair chance of using what's actually present? I'm not afraid to much with config files, I just don't know the underlying system well enough to feel comfortable diving in without a push in the right direction. Thanks guys!

• Is basing storage requirements based on IOPS sufficient?

  - by Boden

  The current system in question is running SBS 2003, and is going to be migrated on new hardware to SBS 2008. Currently I'm seeing on average 200-300 disk transfers per second total across all the arrays in the system. The array seeing the bulk of activity is a 6 disk 7200RPM RAID 6 and it struggles to keep up during high traffic times (idle time often only 10-20%; response times peaking 20-50+ ms). Based on some rough calculations this makes sense (avg ~245 IOPS on this array at 70/30 read to write ratio). I'm considering using a much simpler disk configuration using a single RAID 10 array of 10K disks. Using the same parameters for my calculations above, I'm getting 583 average random IOPS / sec. Granted SBS 2008 is not the same beast as 2003, but I'd like to make the assumption that it'll be similar in terms of disk performance, if not better (Exchange 2007 is easier on the disk and there's no ISA server). Am I correct in believing that the proposed system will be sufficient in terms of performance, or am I missing something? I've read so much about recommended disk configurations for various products like Exchange, and they often mention things like dedicating spindles to logs, etc. I understand the reasoning behind this, but if I've got more than enough random I/O overhead, does it really matter? I've always at the very least had separate spindles for the OS, but I could really reduce cost and complexity if I just had a single, good performing array. So as not to make you guys do my job for me, the generic version of this question is: if I have a projected IOPS figure for a new system, is it sufficient to use this value alone to spec the storage, ignoring "best practice" configurations? (given similar technology, not going from DAS to SAN or anything)

• Physical-to-virtual for personal use

  - by Journeyman Geek

  One of my current projects involves reducing the number of old computers lying around. So far, the office systems have been downsized from 5 to 2. One system which had no data on it was dumped entirely, while three other identical boxes were consolidated into to one (I swap hard drives as needed and they just work(tm)). I want to make further cuts. The physical systems in question all run windows xp sp3, and were old Pentium 4s with 256 MB of RAM. Currently, I have got a VirtualBox running on another system. My intention is to migrate all services to that. We can assume that disk space and RAM on the host is not an issue. I'd rather not go with a client-server physical-to-virtual (P2V) method like what VirtualBox uses now. I have a few specific concerns as well - specifically whether I'd need to reactivate or sysprep for dissimilar hardware first. An offline tool for imaging (Windows or Linux) would not be an issue since the drives could be mounted onto another system I have anyway or I could use a LiveCD. What would be my options for P2V conversion, and what would I need to keep in mind when doing this?
