• Set-and-forget Windows backup software with NAS-support?

  - by Evert

  Hi all, I am looking for set-and-forget backup software for Windows (Vista & 7, and if possible XP/2003). The idea is that it runs in the background on the clients, and does its thing towards a network-share. In case the HDD of one of these clients spontaneously combusts, all I want to have to do is: replace the drive, insert a USB-stick, boot from it, and restore the machine. It should support drives which use [ICH]-RAID. What are my options here? It looks like WHS meets all the requirements, but I am curious about my other options here.

• Terminal Services - MS Access Frequently "Not Responding"

  - by jonfhancock

  Exposition: We use a program built in MS Access that I serve via Terminal Services. I just installed a new TS Server with a Quad Core 2.6GHz Xeon, 8GB RAM, and 4 SATA drives in a RAID 0. In installed Server 2008 R2 (64bit obviously). It's only role is TS. The problem: With just a few sessions (under 10), I start getting frequent Not Responding messages in each session. When it happens, the users aren't doing anything particularly taxing, just form navigation and simple insert queries. I can live with some stalls, but it is visually jarring in WS08 because the screen goes gray, and it presents a dialog offering to wait or close with some other options. Questions: Any suggestions for improving performance and reducing hangs? Is it possible to disable the dialog (always wait) and screen graying?

• Newbie one: Virtual Networks - Hyper-V - Remote Destktop - Only one phisical NIC

  - by josecortesp

  Hello everyone, I'll try to explain my situation and I'll apreciate any help: I have a phisical server (quad core, 4Gb ram, 1TB raid 10, etc) with Win Server 2008 R2 enterprise, running IIS, Printing, etc... Also, I want to set up 2 virtual Servers with 2008 R2 standart one with SQL Server and the other with Team Foundation. What i need is: Being able to access from inside the private phisical network, to Remote Desktops on each of the Virtual and the phisical Servers Had Access from the outside, using a router and port Forwarding, to the TFS server and the IIS server (one is virtualized, the other is phisical) This is it, but note that I only have one Phisical Nic. How do I configure this to work. When i set up the hyper-v role, on the wizard something like it showed up but I don't remmember what i choose, and right now, I cannot access none of the servers from remote desktop, not even from the phisical private network. Can anybody point me, what can i do? Thanks in advance (sorry 4 my english, i'm a spanish talker and my english isn't that good)

• Why Buy Hardrives with storage server from a vendor?

  - by Mark

  Hi all, Im just browsing around at storage server's like the Dell MD100/ MD3000 and the Sun J4200 and although the storage server seems reasonable (approx $3000-$4000 AUD) the hard-drives that you buy to go along with them seems exorbitantly expensive. And I'm not sure why. Surely at most they are using good quality RAID level 7200rpm SATA hdd, but even then they are still charging almost 4 times the price. What is the advantage to buying these from them. I can see if one fails then the vendor replacing it is convenient. But at that price you could buy double the amount of hdd and just claim on warranty directly with the manufacturer. It would be much cheaper and you wouldn't be relying on someone else to fix your problems. Is this the case of "you don't get fired if you buy IBM?" mentality or is there some reason I'm not grasping here? Cheers Mark

• Rough estimate for speed advantage of SAN-via-fibre to san-via-iSCSI when using VMware vSphere

  - by Dirk Paessler

  We are in the process of setting up two virtualization servers (DELL R710, Dual Quadcore Xeon CPUs at 2.3 Ghz, 48 GB RAM) for VMware VSphere with storage on a SAN (DELL Powervault MD3000i, 10x 500 GB SAS drives, RAID 5) which will be attached via iSCSI on a Gbit Ethernet Switch (DELL Powerconnect 5424, they call it "iSCSI-optimized"). Can anyone give an estimate how much faster a fiber channel based solution would be (or better "feel")? I don't mean the nominal speed advantage, I mean how much faster will virtual machines effectively work? Are we talking twice the speed, five times, 10 times faster? Does it justify the price? PS: We are not talking about heavily used database servers or exchange servers. Most of the virtualized servers run below 3-5% average CPU load.

• What software can I use to pinpoint why Windows Server 2003 takes 15 seconds for any operation?

  - by Dr. Zim

  Ram is about 1/2 in use, four CPUs are all but idle. I tried "Microsoft Server Performance Advisor" with no luck. No entries in the Event Log for hardware failures, etc. And yet I can click on the start menu and wait 15 seconds for any new attempt. Launching software takes 30 seconds to respond. The server has an 8 drive WD RE 250 gig each Dell Perc 6 Sata raid array with Intel gigabit network cards. Anyone have any software titles that could analyze what is going wrong with this server?

• insert system disk error after switchting SATA cables

  - by Matthias

  I have 5 hard disks built in my computer, two connected by IDE cables, three by SATA. Today I had to return two of the SATA cables to my room mate. So I grabbed another one I had floating around and connected the remaining disk by unplugging my DVD R/W. Now I receive the 'insert system disk and press enter' error after booting. Disks and cables seem to be fine, since all the disks are recognized in the BIOS. Also, I can mount the disks using a live CD w/o problems. I also tried different orderings of the cables (i.e. plugging the disks in different plugs on the mainboard), I'm not sure if that even matters using SATA. Any Ideas what might be the problem here? The OS installed are Windows 7 and Ubuntu 10, the bootloader installed is GRUB. PS: No RAID involved, JBOD.

• Time Machine for Windows

  - by Kevin L.

  A simple Google search for "Time Machine for Windows" results in a flurry of different little apps. But instead of relying on forum anecdotes and advertisements, I call on the much wiser Super User beta community for some depth on this one. Having Time Machine running on Leopard is like a warm, fuzzy blanket of comfort that I never got with RAID, rsync, or SyncToy on Windows. I'm not asking the community what the "best" backup software for Windows is, but instead: Is there any true Time Machine clone for Windows, one that includes as many of the following as possible: Completely transparent, "set-it-and-forget-it" backup Incremental backups (changes only) for every hour for a day, every day for a month, and every week until the backup disk is full Ability to rebuild from this backup disk in case of main drive meltdown (the backup doesn't have to be bootable; neither are Time Machine disks) Extremely easy to use UI (target user == wife). Bonus points for a beautiful UI

• Windows Disk I/O Analysis

  - by Jonathon

  It appears that we are having a problem with the disk i/o speed on our Windows 2003 Enterprise Edition server (64-bit). As we were initializing a database that created two 1G tablespaces on 3 different machines, it became obvious that the two smaller machines (each 32-bit Windows 2003 Standard Edition with less RAM) killed the larger machine when creating the files. The larger machine took 10x as long to create the tablespaces than did the other machines. Now, I am left wondering how that could be. What programs or scripts would you guys recommend for tracking down the I/O problem? I think the issue may be with the controller card (all boxes are hardware RAID 10, but have different controller cards), but I would like to check the actual disk I/O speed as well, so I have some hard numbers to work with. Any help would be appreciated.

• Does SpinRite do what it claims to do?

  - by romandas

  I don't have any real (i.e. professional) experience with Steve Gibson's SpinRite so I'd like to put this to the SF community. Does SpinRite actually do what it claims? Is it a good product to use? With a proper backup solution and RAID fault tolerance, I've never found need for it, but I'm curious. There seems to be some conflicting messages regarding it, and no hard data to be found either way. On one hand, I've heard many home users claim it helped them, but I've heard home users say a lot of things -- most of the time they don't have the knowledge or experience to accurately describe what really happened. On the other hand, Steve's own description and documentation don't give me a warm fuzzy about it either. So what is the truth of the matter? Would you use it?

• FreeBSD: Samba performance over GBit-Ethernet

  - by Axel Gneiting

  I'm using a FreeBSD NAS with RAID-Z. I can read ~300MB/s from the ZFS disks to /dev/null on the box, but only get about 50MB/s over GBit-Ethernet with SMB to Windows 7 (Samba 3.5.6). Both systems have Intel-PCIe-NICs and are connected directly. Samba is configured to use AIO and I already tried to tune TCP/IP: kern.ipc.maxsockbuf=16777216 net.inet.tcp.sendspace=1048576 net.inet.tcp.recvspace=1048576 net.inet.tcp.sendbuf_max=8388608 net.inet.tcp.recvbuf_max=8388608 net.inet.tcp.delayed_ack=0 Any ideas what's causing the bottleneck? I think the link should handle 100 MB/s easily.

• Email alerts when hard drive fails on a Dell PowerEdge 2950 (PERC5I, SAS)?

  - by BigJoe714

  I recently purchased a used Dell PowerEdge 2950. I setup the hard drives in RAID-5 configuration. I want to be able to get an email alert if one of the drives fails. I have been trying to determine what the easiest way to setup an email alert would be. The controller card is listed as PERC5I, SAS PowerEdge. From my numerous Google searches, it looks like I need to install Dell OpenManage Essentials. However ,this looks to be a giant application with tons of bells & whistles for managing many servers, when all I really want is something for this one server. Can anyone offer me any insight into what I could do?

• EBS+RAID10+XFS slower than EBS+RAID10+EXT3 using MySQL?

  - by Johann Tagle

  We're currently using EC2 with 16 EBS volumes in RAID10 configuration for our MySQL data. I know some people don't recommend to put EBS volumes to RAID but that's not what I'm concerned about at the moment. Current format is ext3, but we're experimenting with moving to xfs, given many reports that it is faster. However, we're actually experiencing a performance degradation when the partition was converted to xfs - a benchmark run with inserts, updates, selects and deletes was more than 10 seconds slower using xfs. Any idea what could be the problem? Below is the fstab entry (really only changed ext3 to xfs). Database tables are innodb and we are using innodb_file_per_table. /dev/mapper/vg_data-lv_data /data xfs noatime 0 0 Thanks.

• Using a non-validated SED on a Dell R720

  - by a coder

  We were given a Dell R720 a couple years ago, and the machine currently has standard 300GB 3.5" SAS 15k drives. Our RAID controller is a Perc H710. We need to update our disks to FIPS 140-2 certified SED. According to Dell, they have only one tested/validated FIPS SED for this machine/controller, but it is a 7200rpm 3.5" unit. I'm showing that Dell offers a 600GB 15k FIPS SED in 3.5" configuration (Dell part number 342-0605), but they say they haven't validated or tested to know if it works. They informed us that we would not void our warranty in using this non-validated drive. How likely is it that our R720 with H710 controller will work with the non-validated drive? Are there significant differences in how drive manufacturers build SED that would prevent them from working consistently across different controllers?

• Install Win7 on Dell XPS1730: CD Driver missing

  - by Mies75

  Vista crashed on my DELL XPS 1730 laptop. Again. I deleted the RAID array, created a new one and started to install Window 7 from DVD. During the initial phase of installation the setup pop ups this: Load Driver: A required CD/DVD device driver is missing... I can then insert other media to load the drivers, but it can't find any. I checked the DELL site for drivers but I can only find firmware for the drive. Which driver do I need, and where can I download it?

• Will this increase my VPS failing rate ?

  - by Spencer Lim

  Will this increase my Virtual private Server failing rate if i :- install Microsoft Window Server 2008 Enterprise install SQL server enterprise 2008 install IIS 7.5 install ASP.Net Mvc 2 install Microsoft Exchange install Team foundation server on one mini VPS with specification of DELL Poweredge R710 shared plan DDR3 ECC RAMs 16GB and -- 1GB for this VPS using DELL PERC 6i raid controller (this thing alone about 1.5k-2k) and the SAS HDD (15K RPM) (146GB) -- 33GB to this VPS each hdd is freaking fast over 300MB read / write possible with proper tuning the motherboard is a DELL and it has twin redundant PSU (870watt 85%eff) its running on Intel Xeon 5502 (Quad Core) x2 so about 8 physical proc (fairly share) is there any ruler for this about one VPS can only install what what what service ?

• Photo Management Software for OS X That Supports Multiple Library Locations

  - by Lance Rushing

  I'm looking at the possibility of changing our photo management software. Thinking about Aperture or Lightroom. And want to know if either supports: Having folders/libraries on separate harddrives/Volumes. Tolerates having network folders occasionally connected Snappy interface A solid enough piece of software as not to crash or behave weirdly. [ so the wife doesn't get stuck and have to call me ;) ] Background The wife is photographer and I'm the computer programmer. Our current setup is Picasa, with a "Recent/Working" folder on the local iMac harddrive, and "Archive" folders on NFS mounted Linux Server, Raid 5, for redundant and extra storage capacity. (the Linux server also syncs with Amazon's EC2) Picasa is doing OK, but I get annoyed when it doesn't do behave properly. Usually around issues when the Linux disk isn't mounted. And overall, I wish Picasa seemed a little more polished and snappier. Thanks, Lance

• Most suitable high availability solution

  - by Alex Bagnolini

  My company is hosting a website in a server with IIS, SQL Server and a 3rd party windows service (written in C#, source code available for amendments). We bought a new identical server, composed by: 1x Quad Core, 12GB RAM, 4x160GB SATA Raid 5, Windows Server 2008 R2 Datacenter, Public IP. We aim to put all webpages and the 3rd party windows service in an high-availability state. After some lab-testing on how to configure Failover Clustering and Hyper-V, we have deep doubts on what the "best" solution would be, by "best" meaning maintainable and able to correctly handle a physical server failure. Any suggestion on how we should configure the two servers? We don't need all the configuration's step, just an hint on the right direction to follow.

• Linux stretch cluster: MD replication, DRBD or Veritas?

  - by PieterB

  For the moment there's a lot of choices for setting up a Linux cluster. For cluster manager: you can use Red Hat Cluster manager, Pacemaker or Veritas Cluster Server. The first one has the most momentum, the second one comes by default with RH subscriptions and the last one is very expensive and has a very good reputation ;-) For storage: - You can replicate LUN's using software raid / md device - You can use the network using DRBD replication, which offers a bit more flexibility - You can use Veritas Storage Foundation technology to talk to your SANs replication technology. Anyone has any recommandations or experience with these technologies?

• How to stop a Linux LVM volume group?

  - by thkala

  I am currently dealing with a multiple disk failure on a Linux LVM Volume Group that is backed up by a RAID-5 md device. One disk has been taken out completely and another one is showing a limited number of corrupt sectors, due to what seems to have been a misbehaving power supply. The problem is that once an I/O error hits, md takes the array down, since it does not have enough devices for it to be operational. Where md the only one involved, I could mdadm --stop the array and then recreate it to get all devices active again. Unfortunately, the array is a PV in an LVM volume group and I cannot seem to get the kernel to release it. vgchange -an does not seem to do anything, bar spew out a couple of I/O errors. I am obviously missing something, but how in the name of -insert-favorite-deity- do I get LVM to release the underlying PV without rebooting the server?

• How to speed up apache

  - by Zen_silence

  We have a server with 8Cores, 16GB of RAM and RAID 0 SAS 10K drives. Our goal is to use this to serve a fairly simple php application quickly. We have tested all other components and we think we have narrowed it down to apache is our bottleneck. I am no apache guru I have done some research and tested a couple things but when i test with JMeter launching 100 concurrent connections against the server the first 10 - 20 come back quickly 30 - 100ms but the rest take between 1000ms to 3000ms. Anyone have any ideas on what to change in our apache config to make this faster right now its a vanilla install of apache.

• Change the location of the System Temp directory on Windows 2003 Server

  - by skylarking

  In order to update an application on a Windows 2003 Server box, the application calls for 2.0 GB of free space in the System's Temp directory. The OS is on C:\ , and there is only 1 GB of free space there.... The server has a RAID configuration for its data on the system's E:\ . There is over 100GB of free space on E:\ . When I did a set tmp I found that the system's TEMP directory is not surprisingly located on C:\ .... TMP = C:\DOCUME~1\ADMINI~1.DES\LOCALS~1\Temp I assume it is possible to change the System Temp directory to the be located on E:\ ? How is this done, where's a good place to stick it, and is it safe to do this ?

• PostgresQL on Amazon EBS volume, realistic performance, or move to something more lightweight?

  - by Peck

  Hi, I'm working on a little research project, currently running as an instance on ec2, and I'm hoping to figure out whether I'm going down the right path. We, like a thousand other people, are making use of some of twitters streaming feeds to do gather some data to have fun with and my db seems to be having problems keeping up, and queries take what seems to be a very long time. I'm not a DBA by trade, so I'll just dump some info here and add more if need be. System specs: ec2 xl, 15 gigs of ram ebs: 4 100 gb drives, raid 0. The stream we're getting we're looking at around 10k inserts per minute. 3 main tables, with the users we're tracking somewhere in the neighborhood of 26M rows currently. Is this amount of inserts on this hardware too much to ask out of ebs? Should take a look at some things with less overhead like mongodb?

• setting up/installing/configuring nginx LEMP stack on fresh VPS server

  - by Grant Tailor

  I need some help in settingup/installing and configuring nginx LEMP stack on a fresh new VPS I have. The specs of the CentOS 5.7 VPS are 2GB DDR3 ECC RAM(4GB burst), 1 core 1.5Ghz(3Ghz burst) and 100GB RAID 10 storage, unmetered bandwidth @ 100Mpbs all for a whopping $25/month(unbeatable, yeah I know :) Anyways I have followed this LEMP (will also need MySQL and PHP) stack guide on linode http://library.linode.com/lemp-guides/centos-5 but basically what I want is to be able to host multiple website on this webserver after everything is setup. I am used to using DirectAdmin control panel on other server and want to have things setup so I can host multiple websites - mostly wordpress and drupal themes. Lets say 10 websites on this nginx web server. So can someone please help me on what I need to do to take "full" advantage of nginx power and performance, while been able to easily manage these multiple websites (wordpress and drupal themes)?

• Should I disable write caching on my Windows 2008 VM?

  - by javano

  I have a Windows Server 2008 x64 Standard virtual machine that runs on a machine with a hardware RAID controller, a Perc 6/i, which has a battery on-board. Doing everything I can for additional performance, I think I should disable this. Is this very dangerous though? My understand is that Battery Backed Write Caching gives a performance boost to the host OS, telling it the write was complete when they are still sitting in flash waiting to be written. However, I can't see how it would be detrimental to performance, but is there a gain (even if marginal) to enabling it / disabling it? P.s. There machine has a backup power. Here is a screen shot for clarification:
