• Migrating away from LVM

  - by Kye

  I have an Ubuntu home media server setup with 4.5TB split across a few hard-drives (1x3TB, 2x1TB) and I'm using LVM2 to manage the volumes. I have recently added a 60GB SSD to my server, and I wish to use it to house the 'root' partition of my server (which is currently under the LVM group). I don't want to simply add it to the LVM volume group, because (afaik) there's no way to ensure that the SSD will be used for the root filesystem. If I just throw it at the VG, it may be used to house my media, which would defeat the purpose of having the SSD in the first place. I feel that my only solution is to somehow remove my root partition from the LVM setup and copy it across to the SSD. My boot partition is, of course, not part of the LVM group. My disk setup is as follows: 60GB SSD: EMPTY. 1TB HDD: /boot, LVM space. 1TB HDD: LVM space. 3TB HHD: LVM space. I have a few logical volumes. my root (/), a 'media' volume for my media collection, a backup one for my network backups.etc. Does anyone have any advice as to how to go about this? My end goal is to have the 60GB SSD used for my boot and root partitions, with everything else on the 3TB/1TB/1TB hard-drives.

• Suggestions on the best home server rack cabinet

  - by allentown

  I have a lot of gear in a colocation facility right now. Some of it is going to come home with me now. I do not know anything about the "rack mount" side of the industry. I lease a rack, and I put my stuff in it. I have a few 1U boxes, a few 2U boxes, and a few 4U boxes. 1U switch. One is a new Xserve, which means it is deep. I think I can get by with around 12U to 18U. I want to keep it as small as possible, since I do not have a lot of spare space at my home. I will not be able to bolt to the wall, floor etc, so it should not be tall. This is something I would love to more or less just be a box that sits on the floor but gives me the ability to mount nicely, do nice cable management etc. Are the "post" style racks junk? I am liking the open space, and the no limitations on depth of something like this: http://www.rackmountsolutions.net/images/products/Martin-relay-rack.jpg However, that thing is way too tall, and probably way too expensive. I am looking to be around $300.00 or less. More if I have to, though I would prefer not to. These look near perfect: (See comment for this link, the system will not let me post a second url) but I am worried the Xserve will not fit in it. If anyone has any good links, or website recommendations of good past experience, I would appreciate it. I am almost considering that I may be able to build something with random scraps of stuff at Home Depot as well.

• Having trouble mapping Sharepoint document library as a Network Place

  - by Sdmfj

  I am using Office 365, Sharepoint Online 2013. Using Internet Explorer these are the steps I have taken: ticked the keep me signed in on the portal.microsoftonline.com page. It redirects me to Godaddy login page because Office 365 was purchased through them. I have added these sites to trusted sites (as well as every page in the process) and chose auto logon in Internet explorer. Once on the document library I open as explorer and copy the address as text. I go to My Computer and right click to add a network place and paste in the document library address. It successfully adds the library as a network place 30% of the time. I can do this same process 3 times in a row and it will fail the first 2 times and then succeeds. It works for a little while and then I get an error that the DNS cannot be found. I need multiple users in our organization to be able to access this document library as if it was a mapped network drive on our local network. Is there an easier way to do this? I may just sync using the One Drive app but thought that direct access to the files without worrying about users keeping their files synced.

• PC won't PXE boot to WDS/MDT with Dell Optiplex 755

  - by Moman10

  I am trying to set up a basic MDT solution. I have set one up in the past at a previous job and it worked flawlessly, however here I'm running into a problem and am having no luck getting around it. I've installed Windows Server 2012 and MDT 2013, along with adding on the WDS role. I haven't configured much outside of the defaults for WDS, basically just set PXE response to respond to all clients (and unchecked admin approval). This machine does not run a DHCP server. I looked on the DHCP scope of our DHCP server, it shows options 66/67 checked and the server name of the WDS server is in there as well. I didn't add this but I assume it was put on during the install process (I believe I had to manually make some adjustments at my old job for this). The PC I have is a Dell Optiplex 755. I have enabled the onbard NIC w/PXE boot option in BIOS and attempted to boot. I get a "TFTP...." error but nothing offering out a DHCP address like I'm used to. In my previous job it pretty much worked right out of the box. I've verified that PortFast is enabled on the port and I've tried a couple different PCs (but both are the same model, only model I have to work with). No matter what, I get the same error. The subnet the PC is in is a different subnet than where the WDS server is sitting, but there are IP helper statements on the switch and the PCs can get regular DHCP addresses just fine from the DHCP server, just doesn't seem to get offered out a PXE boot option. I don't know if the problem is a configuration with the server or the PC itself...but after a few days of Googling I'm running out of ideas. Does anyone have a good idea of something it may be?

• How to set up GRUB2 chainloader to other Grub (Fedora, Debian) on GPT

  - by basic6

  I'm trying to set up a dedicated GRUB2 which (chain-)loads another GRUB on a disk with GPT partition table. Relevant partitions: /dev/sda1 BIOS_BOOT /dev/sda2 BOOT (ext2) /dev/sda3 FEDORA (ext4) /dev/sda6 DEBIAN (ext4) I installed Fedora first, using /dev/sda2 as boot partition. Then I installed Debian. The Debian installer recognized the Fedora installation and added it as boot entry, then installed its GRUB into the MBR. While this works for the moment, it's pretty messy, because every Debian update may change the boot config, removing the Fedora entry (tried it) and the other way around. That's why I want both systems to have their own boot loader and one main boot loader (that could reside on /dev/sda2), which loads one of them. This is what I've tried: Moved everything from /dev/sda2 to /dev/sda3/boot Removed /boot mount point in Fedora (so /dev/sda2 isn't used anymore) From a live Linux, installed GRUB2 to the MBR (grub-install --boot-directory=sda2 /dev/sda) Wrote a menu.lst: title Fedora root (hd0,2) chainloader +1 (Again, for Debian) Converted that to a grub.cfg script (grub-menu2cfg or something like that) When booting, actually got a GRUB2 menu with "Fedora" (and "Debian") When selecting any one of those: error: invalid signature Issued "grub-install /dev/sda6" (and ...sda3) from all kinds of live Linux systems, all of which failed with another error message (in the case of the Debian installer, without explanation at all) Added --force to the chainloader line, now it says "loading", then reboots Found douzens of howtos, none of which seem to work for me Since I get the self-made GRUB2 menu on bootup, I've at least successfully installed the first stage of GRUB, right? When trying to chainload, some signature is checked and seems to be wrong - how do I fix it? The boot menus (Fedora with its different Kernel versions and Debian with Debian and Fedora as well) are now on the system partitions (/dev/sda3, /dev/sda6), is there anything else to do on these partitions, so they can be chainloaded? Any help is greatly appreciated.

• Offline copies in Windows file sharing

  - by netvope

  I frequently access media files (music or video) on a remote Windows file share. My Internet connection is not very fast, and I find it a waste of bandwidth when I repeatedly access the same files. For example, I may listen to the same song 30 times in a month. So, I would like to cache files I've used. I know Windows has an "Always available offline" feature but I think it doesn't suit my needs. I don't want to make the whole share "available offline" as the remote Windows file share is huge (in terabytes). Making individual files "available offline" is tedious as the files are scattered in many different directories. It would be much more convenient if I can simply cache those I've used. Also The files on the share seldom change. Many of the files are rarely used. Some of the files are frequently used. I don't have a list of the most frequently used files. So I think the best way is to have a caching proxy for the Windows share. What do you think? I have a Linux box sitting around. Perhaps I should try to setup samba4?

• Scheduling Automatic Backups for Virtual Private Web Server running CENTOS 6.3 and WHM

  - by Oliver Farrell

  I'm pretty new to administering my own VPS - but thus far am finding it quite a compelling experience. There's something quite refreshing about having complete control over everything it does. One thing that I would like to look at is a suitable backup solution (a few times a day). My current setup is as follows: I'm running a CENTOS 6.3 VPS with a single 25GB hard drive solely for the purpose of hosting websites. I'm using WHM & cPanel for administering them. I now plan on adding an additional hard disk and hooking it up to my VPS. What I'm not sure about is how I get the two disks talking and get the backup process going. I'm not a seasons SSH-er so don't really know where to start. I'm hosting with Serverlove (one of the best hosting providers I've used) and am provided with a number of unique identifiers for each hard disk so I imagine these may play a part in linking them together. I appreciate that this is a little vague (I'm clutching at straws) but any assistance is very much appreciated.

• Maximum limit of filepointer in php reached and not changeable

  - by mlaug

  I have a server with the current 5.3.x version installed. Since we are running a really simple and small server in php using sockets, that connects to a lot clients using sockets we need to raise the open file limit that has been already done on the server for the user, that runs the server #ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 29879 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 8192 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 29879 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited and we compiled php with --enable-fd-setsize=8192 still we are getting [19-Nov-2012 09:24:23 Europe/Berlin] PHP Warning: socket_select(): You MUST recompile PHP with a larger value of FD_SETSIZE.

• Hyper-V Virtual Machine won't respond over network

  - by Brad Gignac

  Recently, one of our Hyper-V virtual machines has periodically stopped responding over the network. It seems to be happening every few days, and it occasionally happens up to several times a day. I am by no means a sysadmin, so any direction you guys could provide would be very welcome. I've included everything I know to include below. If you need any additional information, I'll be glad to include it. I can connect through the Hyper-V console. I can't connect to network shares, IIS web apps, using RDP, or using ping. Memory usage seems to be normal (3 of 4 GB) Processor usage seems low. We don't know the exact time the server goes down, but the following error appears consistently around the time it goes down: Error 5719, NETLOGON This computer was not able to set up as secure session with a domain controller in domain *** due to the following: There are currently no logon servers available to service the logon request. This may lead to authentication problems. Make sure that this computer is connected to the network. If this problem persists, please contact your domain administrator.

• How to install rmagick on Ubuntu 10.04?

• How can I make Internet Explorer 6 render Web pages like Internet Explorer 11?

  - by gparyani

  Now, I know that this may seem like a bad question in that I can just upgrade to Internet Explorer 8, but I am sticking with IE6 in that IE8 removes valuable features, like the ability to save favorites offline and the fact that a file path turns into a Windows Explorer window and typing a Web address into Windows Explorer changes it into an IE window. I know that Internet Explorer 6 does a really bad job at rendering some pages. I know of the Google Chrome Frame extension that brings Chrome-style rendering into IE, but that will soon be discontinued. So, I tried another thing: I know that C:\Windows\System32\mshtml.dll contains the Trident rendering engine that is used by IE, so I tried something: I first backed up the original file by renaming it on Windows XP to mshtml-old.dll, then I tried to copy in the DLL from a computer running Windows 7 with Internet Explorer 10. I noticed that, after copying, the system had replaced the new DLL with the old one, but left the one I backed up intact. Is there any way I can get the system to not replace the DLL like that so that I can transfer in IE11's mshtml.dll into Windows XP and make IE6 render like IE11? I'm looking for an answer that describes how to tweak my system to make IE6 render like IE11 (or IE10), not one that tells me to upgrade IE or install another browser. I don't care how tedious the method is, just as long as it works.

• Does btrfs balance also defragment files?

  - by pauldoo

  When I run btrfs filesystem balance, does this implicitly defragment files? I could imagine that balance simply reallocates each file extent separately, preserving the existing fragmentation. There is an FAQ entry, 'What does "balance" do?', which is unclear on this point: btrfs filesystem balance is an operation which simply takes all of the data and metadata on the filesystem, and re-writes it in a different place on the disks, passing it through the allocator algorithm on the way. It was originally designed for multi-device filesystems, to spread data more evenly across the devices (i.e. to "balance" their usage). This is particularly useful when adding new devices to a nearly-full filesystem. Due to the way that balance works, it also has some useful side-effects: If there is a lot of allocated but unused data or metadata chunks, a balance may reclaim some of that allocated space. This is the main reason for running a balance on a single-device filesystem. On a filesystem with damaged replication (e.g. a RAID-1 FS with a dead and removed disk), it will force the FS to rebuild the missing copy of the data on one of the currently active devices, restoring the RAID-1 capability of the filesystem.

• Grant HTTP access based on unix user group

  - by Sander Marechal

  Is it possible to grant network access or HTTP access based on a user's group? At my company we want to set up an internal composer server using Satis to manage packages for the projects we write (e.g. on repository.mycompany.com), with the packages themselves in our SVN server (svn.mycompany.com). We have several webservers with many different users on them. Some users should be able to reach the composer and SVN server. Some should not. Users that should be able to reach these servers all belong to the same group. How can I set up Apache on the Composer and SVN server to only grant access to those users in that group? Alternatively, can I set up the webservers in such a way that only users from that group are able to make a connection to our Composer and SVN servers? The best thing we have come up with so far is using SSL client certificates. We simply place a client certificate on all servers which can be used to access Composer and SVN. Only the right usergroup will have read access to the certificate. A bit clunky but it may work. But I'm looking for something better.

• Copy/paste filtered column in Excel - error message

  - by hazymat

  Firstly I should state that I don't believe in spreadsheets; my normal mode of operation is that data should either exist in a database or a text file... However - employment requires... In short, I have filtered a worksheet by column A, and I want to copy/paste from column B to column C. Obviously I don't wish to copy/paste values from rows that were filtered-out here. The above sounds ridiculously simple, right? First I tried simply copy/pasting on the filtered worksheet. This appeared to select and copy only the filtered data, however pasting appeared to insert values into hidden/filtered rows - as you might expect. So my initial research suggests I may wish to select the filtered data and press Alt+; (that is, ALT plus semicolon), which is a shortcut key for Goto Special Select Visible. Then just copy-paste. CTRL+C correctly copies the filtered data, however when I go to paste the values into another column, it pastes into hidden rows as well. Okay, so perhaps I should also "Select Visible" on the cells I wish to paste into as well? Nope - that gives me the error That command cannot be used on multiple selections. What am I doing wrong?!

• Cannot Update Adobe Creative Suit

  - by Lynda

  I am attempting to check for updates using the Adobe Application Manager on Windows 8 and I get this error: The update server is not responding. The server might be offline temporarily, or the Internet or firewall settings may be incorrect. I have seen this error before on Windows 7 and remembered that I needed to disable the Microsoft Virtual WiFi Miniport Adapter. I navigated to the correct place but the Miniport Adapter was not there. After a bit of searching across several forums I saw a recommendation to change <logLevel>2</logLevel> to <logLevel>10</logLevel>. I attempted that and again it still did not work. I have also tried disabling my anti-virus protection and disabling Windows Firewall. Neither worked. I am not sure what else to try or do at this point. Are there any other recommendations to solve this issue? Notes: I am running Windows 8 Pro using the Creative Cloud Version of CS6. I check for updates by choosing Help Updates from within any Adobe Application I originally posted this question on the Adobe Forums and received no help there.

• VPN Client solution

  - by realtek

  I have several VPN's that I need to establish on a daily basis but from multiple workstations. What I would like to do it have either a server or vpn router that can perform this connection itself and that I can then route traffic through this device or server depending on the subnet I am trying to reach. The issue is that I only use VPN Clients to connect, so I am basically trying to achieve almost a site to site VPN but by using basically a VPN Client type connection from my network. The main VPN Client I use is the Sonicwall Global VPN Client where I initially use a Preshared Key and then it always prompts me for a username and password (not RSA key). My question is, is there any type of linux distro or even a hardware vpn router that can do this and connect to a Sonicwall device as if it were a client? I have tried pfSense which is very good but it fails to connect, probably due to a mismatch of settings. I have tried many others. Even dd-wrt on my router but it does not support whatever protocol Sonicwall uses. (I thought L2TP/IPSec) but it appears it may not be that. Any advice would be great! The other other thing I have thought of that I have not tried yet is Windows Server Routing and Remote Access but I have a feeling that won't work either. Thanks

• How can I find a list of all SSE instructions? What happens if a CPU doesn't support SSE?

  - by Blastcore

  So I've been reading about how processors work. Now I'm on the instructions (SSE, SSE2, etc) stuff. (Which is pretty interesting). I have lot of questions (I've been reading this stuff on Wikipedia): I've saw the names of some instructions that were added on SSE, however there's no explanation about any of them (Maybe SSE4? They're not even listed on Wikipedia). Where can I read about what they do? How do I know which of these instructions are being used? If we do know which are being used, let's say I'm doing a comparison, (This may be the most stupid question I've ever asked, I don't know about assembly, though) Is it possible to directly use the instruction on an assembly code? (I've been looking at this: http://asm.inightmare.org/opcodelst/index.php?op=CMP) How does the processor interpret the instructions? What would happen if I had a processor without any of the SSE instructions? (I suppose in the case we want to do a comparison, we wouldn't be able to, right?)

• HP G61 Laptop wont boot- display stays off, caps and num lock indicators blink repeatedly

  - by Benguy12

  I had my HP G61 laptop running in sleep for a while. When I came back to it about a half-hour later, it was no longer in sleep mode - the power light and the Wi-Fi indicator light were on (I keep Wi-Fi off becuase I use a wired connection) - but nothing was showing on screen. In fact, the display wasn't even turned on. So I let it sit for about 10 minutes but nothing happened. I did a force shut down and rebooted. Instead of a normal boot, the display didnt turn on, the Wi-Fi indicator was off, and the Caps Lock and Num Lock lights just blinked repeatedly. On the external keyboard i use, none of the light indicators were blinking or even on. I tried force shut-down again 10 times, then unplugged all connections except for the power cable (my laptop battery dosent hold a charge for more than 2 minutes, so I always must have a wall connection) and tried to boot again but still nothing happened. I unplugged the battery and even then nothing happened. I also tried booting with the disk drive open, and then with it closed again. On the time it was closed, I was able to successfully boot into Windows, but recieved a "Windows did not shut-down sucessfully" notice. Does anybody know why this may have happened? My PC's specs: Windows 7 Home Premium, 64-bit 4GB of physical RAM, 8GB of vRAM (on a flash drive) AMD Vision x64 processor (don't know any other specs about it) ATI Radeon graphics card, 392 MB DVD-R/W lightscribe drive 2 External hard-disks (first one is 1.5TB, second one is 1TB) custom boot-screen and boot-annimation Standard BIOS apps running before sleep: firefox 10.4 itunes 10.6 adobe photoshop extended CS5.1 rockstar games social club (running in background) microsoft powerpoint 2010 professional edition google chrome I was NOT running Aero or any fancy themes - I was using the normal windows classic theme.

• Error setting up Data Protection Manager 2010 Agents / Network "Unauthenticated" in network settings

  - by Bowsa

  I'm not sure if the two are connected but i suspect they are. Basically I'm tring to setup Data Protection Manager 2010 on a fresh install of Server 2008 R2 in a SBS 2003 domain. Everything went fine until trying to install agents across the network. Upon clicking add, i get the following error message: Unable to connect to the Active Directory Domain Services Database. Make sure that the DPM server is a member of a domain and that the controller is running. Also verify that there is network connectivity between the DPM server and the domain controller. ID: 7 As usual (worryingly) the MSDN support for 2010 products is nearly non existant, clicking the error ID simply gives a page not found error. So after 2 days of Googling and trying various fixes (DNS settings, adding permissions to AD objects, rejoining the domain and many more) I thought I'd ask here in the hope that someone out there may have had this issue before. Any help greatly appreciated! Some further info: Firewalls are disabled on the Server 2008, SBS, and client machines. Manually installing and adding the client in also fails, as the DPM server tries to contact the DC first. Edit: I tried creating a new protection group instead, and it gives a different error upon adding the machines: Following machines are not found in AD: COMPUTERNAME.COMPANYNAME.LOCAL Is there a certain directory structure it follows in AD?

• Measure Total Bandwidth for Billing

  - by TonyZ

  I am setting up a new network which customers will host their applications on. It needs to be able to scale out to a few hundred servers and each server will have several VMs on it. Right now in my test environment, after the telco router, we are using a Linux router/firewall which is then connected to a Layer 2 switch. Could be a layer 3 in the future. I need to track total bandwidth per VM for each machine, and I need to do it in a way that it is not part of the VM. Each VM will have a private class ip address which is Natted by the gateway, or we may eventually run more than firewall/reverse proxy off a layer 3 switch. So my thinking is that I can do it off of a promiscuous port on the switches, or at the gateway firewall. I would like to have an out of the box solution, preferably open source. Does anyone have suggestions on the easiest way to set this up, and the easiest tool to use. I have looked at the web sites for Nagios, Zenoss, Zabbix, ntops on the firewall, etc. It is hard to ascertain just from the web sites if they do exactly this or not. Obviously, performance is also somewhat key here. Anything running on the gateway should not drag it down doing traffic accounting. Thanks for any thoughts. Tony Zakula

• libsasl2 change paths

  - by mk_89

  I have been following the tutorial https://help.ubuntu.com/community/Postfix for installing Postfix on ubuntu. Im stuck at the Authenication section of the tutorial where you change paths to live in the false root, if you look at the link above I have a file (/etc/default/saslauthd) which is pretty much the same as the one from the tutorial. saslauthd # This needs to be uncommented before saslauthd will be run automatically START=yes PWDIR="/var/spool/postfix/var/run/saslauthd" PARAMS="-m ${PWDIR}" PIDFILE="${PWDIR}/saslauthd.pid" # You must specify the authentication mechanisms you wish to use. # This defaults to "pam" for PAM support, but may also include # "shadow" or "sasldb", like this: # MECHANISMS="pam shadow" MECHANISMS="pam" # Other options (default: -c) # See the saslauthd man page for information about these options. # # Example for postfix users: "-c -m /var/spool/postfix/var/run/saslauthd" # Note: See /usr/share/doc/sasl2-bin/README.Debian #OPTIONS="-c" #make sure you set the options here otherwise it ignores params above and will not work OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd" When I run the following command in ubuntu dpkg-statoverride --force --update --add root sasl 755 /var/spool/postfix/var/run/saslauthd I get the following error dpkg-statoverride: warning: An override for '/var/spool/postfix/var/run/saslauthd' already exists, but --force specified so will be ignored. dpkg-statoverride: warning: --update given but /var/spool/postfix/var/run/saslauthd does not exist I don't why this is happening, I literally followed the tutorial step by step and have installed all the packages necessary, what could be the problem? do I have to manually create

• PowerPoint avoid animation completion on click & advance slide or start new one

  - by ScottS

  Scenario I have PowerPoint 2010 On the "Transitions" tab the "Advance Slide On Mouse Click" check box is checked. I have a long, slow, timed, non-repeating animation working in the background of the slide. I click to advance the slide before the animation is finished, but ... Instead of advancing the slide, the animation moves to the completed state ... Forcing a second click to actually advance the slide. Additionally If I have other animations on the slide that are initiated by a click, the long animation also advances to a finished state before starting the new animation. Desired Behavior On click, I want the slide to advance or the next on-click animation to start whether the long animation is done or not, and without having that long animation first "complete" itself. In the case of another animation, I simply want the long animation to continue, while also doing the new animation. Ultimate Question Is there a way to either: Set an option somewhere to not have that animation complete on click and simply "continue" to animate with the start of a new animation or to advance the slide (as the case may be)? Create a VBA script that will produce the desired behavior for the long animation?

• Small Business HP Virtualisation and iSCSI SAN Options

  - by Robin Day

  We are a small business that hosts our core product on a number of HP servers. Our core production setup is 1x HP DL380, high powered for a SQL Server Database 1x HP DL360, mid powered for our core application server 6x HP DL320, low powered for our front ends We run our training / testing / support systems on a similar setup, the servers are just older and less powerful. Unfortunately this is now causing us issues as the system has grown beyond the capabilities of these older servers. Upgrading these servers would be expensive and we believe that virtualisation is probably the way to go for the future. Locally we run a number of test / dev environments on ESXi using Direct Storoage on a couple of high powered DL360's and these are performing fairly well. We're thinking that instead of replacing all of our test servers that we can implement an iSCSI SAN and one or two high powered hosts. Hopefully looking that when it comes to replace our live servers as well that we can just expand the virual environment to cope. So my question is... Can anyone offer any advice on some suitable options? We have generally always been extremely happy with HP servers, all of our kit is currently HP, therefore our preference would be to stick with HP, however, I'm always happy to hear about other options. I'm hoping that initially a budget of around 15-25k (GBP) would be suitable, this could potentially be increased if I had confidence that the system would pave the way for a cost effective upgrade of our live systems in the future as well. I am new to SAN's and my only real experience is playing with OpenFiler on some old desktops. I think iSCSI should be suitable, but I've not done any research into how SQL server may perform. I've had a browser through HP's sites and see plenty of information about EVA, MSA, LeftHand, etc. However, from looking at all that, I don't see which options would be best and more importantly I don't know exactly what I would need to buy. Any help, links, opinions would be much appreciated. Thanks
