• System Center 2012 VMM UI is very slow

  - by Grant

  I've recently setup system center 2012 a new server 2008 r2 server which I'm using for virtual machines. Everything seems to be working fine, and the virtual machines are nice and fast. But the Virtual Machine Manager interface is always excruciatingly slow. Sometimes taking up to 15 seconds moving between screens. It's very frustrating trying to use it when a task that just involves a couple clicks ends up taking several minutes. Pages that have a lot of form fields seem to take the longest to load - such as the page to change hardware settings of a virtual machine. Is this just normal performance for VMM? If not, where can I look to find what is slowing it down. Nothing else on the system seems to suffer. I can load and use Hyper-V manager with no noticable slowness. Even programs like event viewer that are usually rather slow seem to load fairly fast. Only the system center programs seem slow. Server is a Dell R710, 2x16 core opteron 6274 processors, 96GB RAM. OS drive is 2x500GB 7.2k RPM SAS drives in RAID1 (opted for the less expensive 7.2k drives since pretty much everything is stored on the SAN). Am I just being impatient? Does anyone else use VMM 2012 and find it slow?

• realtek lan driver problem - win 7

  - by tango _123

  Hi, my new notebook (ACER TM 8371) with Win 7(x32) professional as OS, has strage behaviour with respect to LAN. when I plug or unplug my charger cable, or my notebook goes in stad-by, or just a do nothing, the netwrok connection is lost. All the energy savings functionbality have been in-activated. if i check the network adapter information, it says "a network cabel is unplugged or corrupted", but it is not true.....the cable is in and it is not corrupted (i tried several which works on other machines). if a tried to di-habilitate and hence re-habilitate, it allows di-habilitation and not to further re-habilitate (it says "no driver for the network card" are available). in some cases, also, the driver disappears (i cannot see it anylonger). if i restart the notebook, everything comes back to normality, but.....today in 3 hours i had to restart 6 times!!! can anyone help me? win 7 says the driver is the last one, so no need to update it. here are some techinical information aboiut network card and driver: Name [00000015] Realtek PCIe GBE Family Controller Adapter type Ethernet 802.3 Product type Realtek PCIe GBE Family Controller Installated YES ID device PNP PCI\VEN_10EC&DEV_8168&SUBSYS_02831025&REV_02\4&266E4C4F&0&00E2 last reset 20/11/2009 11:27 Index 15 Service name RTL8167 I/O Port 0x0000FF00-0x0000FFFF Memory address 0xE2500000-0xE2500FFF Memory address 0xE1400000-0xE140FFFF IRQ Channel IRQ 18 Driver c:\windows\system32\drivers\rt86win7.sys (7.3.522.2009, 164,00 KB (167.936 Byte), 28/08/2009 22:12)

• Firefox v15.0 about:newtab inaccessible via the back button

  - by Willem

  As of this morning I upgraded my Firefox to version 15.0. Or well, it did it for me. That's when my issue began. I've configured Firefox so that when I open up a new tab via Ctrl-T that it loads the about:newtab page which was released in version 14.x(?). I use this functionality extensively. I visit a page from the about:newtab page, read it, press the back button and pick another frequent website from the display I want to visit. However as of v15.0 the latter part is no longer functioning, after visiting a website from the about:newtab page the back button will not let me go back to the about:newtab page. Firefox acts as if that history entry was never there. I've tried searching the release notes to see if this change was intentional or a reported bug, but I have not found anything related so far. Is there anyway to (re)configure the new Firefox v15.0 to let me access the about:newtab page via a tab's history? EDIT: It appears that this only affects the initial 'visit' to the about:newtab page when opening a new tab, manually visiting about:newtab will register it as a history entry and allow it to be navigated to via the back and forward buttons. So I guess this changes my question to 'How can I make Firefox 15.0 treat the inital page from a newtab as a history entry'.

• I think my laptop just died

  - by Joel Coehoorn

  I have a Dell 1330M that as of about 15 minutes ago will no longer POST. What happened was I was working, stepped away for a moment, and when I came back it was turned off. I thought that was odd, but turned it on and things seemed fine. About 1/2 hour later it crashed and restarted, but came up fine again. It did this once more. At this point I was starting to get worried, but I hadn't had any problems with the laptop before and every crash was after doing some work in a virtual machine that I don't often use, so I at put the blame there. It didn't feel like it was overheating anywhere and there's no ozone smell of overheated electronics. Then it crashed a final time and now when I turn it on all I see is a bright screen with a bunch of vertical lines (noise). I've tried removing the memory sticks one at a time, but I get the same result with either memory stick in either slot. With no memory at all it stops earlier in the POST process and the screen is completely blank (black, no backlight). As I type this, I hear a double beep from the system about once every 10 minutes. I'm pretty sure the hard drive is fine because it fails during post, before anything off the drive is needed. The power supply seems good because the screen is nice and bright. It's not the RAM because swapping that around made no difference. The leaves motherboard (which I doubt and can replace) and CPU (which just might be changable). Any ideas? Is there any hope for this laptop? I'm rather fond of it and I'd have a hard time replacing it with anything near as nice.

• NFS-shared file-system is locking up

  - by fredden

  Our NFS-shared file-system is locking up. Please feel free to ask any questions you feel relevant. :) At the time, there are a lot of processes in "disk sleep" state, and the load averages on our machines sky-rocket. The machines are responsive on SSH, but our the majority of our websites (apache+mod_php) just hang, as does our email system (exim+dovecot). Any websites which don't require write access to the file-system continue to operate. The load averages continue to rise until some kind of time-out is reached, but for at least 10-15 minutes. I've seen load averages over 800, yet the machines are still responsive for actions which don't require writing to the shared file-system. I've been investigating a variety of options, which have all turned out to be red-herrings: nagios, proftpd, bind, cron tasks. I'm seeing these messages in the file server's system log: Jul 30 09:37:17 fs0 kernel: [1810036.560046] statd: server localhost not responding, timed out Jul 30 09:37:17 fs0 kernel: [1810036.560053] nsm_mon_unmon: rpc failed, status=-5 Jul 30 09:37:17 fs0 kernel: [1810036.560064] lockd: cannot monitor node2 Jul 30 09:38:22 fs0 kernel: [1810101.384027] statd: server localhost not responding, timed out Jul 30 09:38:22 fs0 kernel: [1810101.384033] nsm_mon_unmon: rpc failed, status=-5 Jul 30 09:38:22 fs0 kernel: [1810101.384044] lockd: cannot monitor node0 Software involved: VMWare, Debian lenny (64bit), ancient Red Hat (32 bit) (version 7 I believe), Debian etch (32bit) NFS, apache2+mod_php, exim, dovecot, bind, amanda, proftpd, nagios, cacti, drbd, heartbeat, keepalived, LVS, cron, ssmtp, NIS, svn, puppet, memcache, mysql, postgres Joomla!, Magento, Typo3, Midgard, Symfony, custom php apps

• SVN client too old after I used sshfs

  - by johnlai2004

  I have a svn checked out web application on a shared hosting linux server. The linux server has an svn client that I can access via ssh. From my localhost, I did the following > sshfs [email protected]:webappdir/ /media/webapp > cd /media/webapp > svn update svn: Working copy '.' locked svn: run 'svn cleanup' to remove locks (type 'svn help cleanup' for details) > svn clean up It's been 15 minutes and the svn clean up still isn't finished. I think it may have froze. So then I did the following: > ssh [email protected] > cd webappdir > svn update svn: This client is too old to work with working copy '.'; please get a newer Subversion client So now I can't update my webappdir because my /media/webapp is stuck on svn clean up, and my shared hosting server's svn client is out of date. I don't have privileges to install a new svn client on the shared hosting server. How do I get my svn update to work?

• How can I confirm that burn process was completed successfully??

  - by infant programmer

  Just now I tried to make a duplicate copy of my Windows XP Pro SP3 CD. I had set 32X speed while the max speed allowed is 48X. And checked "Verify the Data after burning". I didn't observe how much % did it complete. But after 15 mins (which is sufficient period to burn disc), I heard "Fatal Error" sound. When I saw the monitor, There was a message box which was showing "Error while burning Disc", I saved the error log which you can find here click_me. How do I acknowledge that burning process is done?? Well. my PC is able to read the CD and CD is bootable too.. I am not sure .. whether the burning process got failed or the verify Process! Please let me know if you have come across or aware of such situation .. As it is XP installation CD .. I don't want to do trial and error method. regards,

• Snow Leopard takes a long time to connect to Windows/Samba server

  - by hood

  We run a very heterogeneous network here: There is some XP, Vista, 7, Leopard, Snow Leopard clients, and Windows 2003 (one remaining legacy app), 2008, and Linux servers. The main file server runs Ubuntu Linux and has been added to the Windows Domain and has been used for many years; SBS 2008 is the PDC (the 2003 and 2008 are on the domain also). In Leopard there were no problems at all authenticating to the file servers. We've upgraded one of the Leopard iMacs to Snow Leopard, though the same problem occurs in a new MBP which came with the newer OS as well as a clean install on another iMac. It does not matter whether connected through wired or wireless. In the Finder when clicking on the server - whether on first boot or after it is connected - it will display "Connecting..." for up to a few minutes before either generally working (if username/password in keychain) or displaying "Connection Failed" - at which time clicking "Connect As" and typing in the username/password will take some more time and eventually work. Sometimes it will display "Connecting..." indefinitely. (I've left it as long as 15 minutes before trying something else) Accessing shares on the the 2003 and SBS servers have the problem (so I don't think it's a Samba server issue). The Server 2008 Standard is connecting instantly at the moment. Accessing the share through an alias/stacks doesn't have this problem. Leopard and Windows clients still have no problem. I've searched Google but hasn't yielded any working result. How do I get rid of this delay?

• hyper-v cluster behavior when losing network connectivity

  - by ChristopheD

  Setup: (rather new) Hyper-V R2 cluster with 2 nodes (in failover configuration). Fysical host OS: Windows Server 2008. About eight VM's (mixed: Windows Server 2008 and Linux) Yesterday we had a power outage of about 15 minutes. Our blades are on UPS so the fysical host machines (Windows Server 2008) never went down. Our main switches are not on UPS (yet) and we saw the behaviour similar to the following (as distilled from the event logs). The nodes in the cluster lost means of communication (because the external switches went down). The cluster wants to bring down one (the first) of the nodes (to start failover?). The previous step impacts clustered storage where the virtual machine VHD's are located. All VM's got brutally terminated and were found in a failed state in the failover manager in the host OS'es. The Linux VM's were kernel panicking and looked like they had their disk ripped out. This whole setup is rather new to us, so we are still learning about this. The question: We are putting switches on UPS soon but were wondering if the above is expected behavior (seems rather fragile) or if there are obvious improvements configuration-wise to handle such scenario's ? I can upload an evtx file concerning what exactly was going on in case that's necessary.

• ssh works fine when using public interface, but slow when using private interface

  - by Kevin M

  My Linux(UbuntuEEE) to Linux(CentOS) ssh takes a long time to log in(~15 seconds) when using the private interface, but not when using the public one. I have a Linux box acting as my router. As such, it has multiple interfaces(75.xxx.xxx.xxx, 192.168.1.1). I can ssh in from the internal interface(192.168.1.65 to .1), but it will take a while. I can ssh into the public address, and it goes quickly(~1 second). I have another box that I can ssh into the inside interface from and it goes quickly. iptables is set to accept packets coming into the interface immediately. sshd's UseDNS is normally on; I get the same problem if I turn it off and restart sshd. I normally use public-key authentication; I have done a mv ~/.ssh/ ~/ssh/ and it will ask me for a password after going slowly. After logging in(using either interface), speed is quick. ssh client version(via ssh -v):OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007 ssh server version(via rpm -qv openssh_server):openssh-server-4.3p2-29.el5

• Outlook 2010 Crashing Unpredictably

  - by cbkadel

  Very often when I open up Outlook 2010 and start doing actions in it, it will hang and become non responsive. I have tried letting it finish, but it never does come back (up to 20 minutes of letting it try). I generally have to restart Outlook and try again. Usually after about an hour of doing this, Outlook somehow snaps out of it and works for the rest of the day. It's generally in the morning (though I doubt that's the key variable). Generally, the emails that cause problems are HTML/formatted, but not always. What I've done so far to troubleshoot: Install Latest Outlook Hotfix (I think Dec 14, 2010) Start Outlook in Safe Mode Neither of those steps seem to make a difference. Usually - after about 10-15 restarts of Outlook on any given day, then it starts working thereafter. My next step is to uninstall/reinstall Office 2010, but I'm hoping someone has seen this and knows what to do about it - though not sure. My configuration is like this: Microsoft Online Services (using Microsoft's Sign In App) - Connecting to Exchange I have two other Exchange accounts in this profile (new feature in 2010) connected through Outlook Anywhere. Life Meeting Conferencing Add In I've disabled the People tab/add in. I've disabled the "Send to Bluetooth" add-in. Not sure what else to do. Thanks in advance.

• Can't run utilities/.exe's that use the network from a [DFS] windows share on Windows 2008 servers. Can this be overcome?

  - by Jim Lawhon

  Under Windows Server 2008 I'm unable to run many utilities that use network resources. This works just fine under Windows Server 2003. For example: \\domain\dfs\tools$\bin\sendmail.exe ... \\domain\dfs\tools$\bin\psexec.exe ... echo %_metric% %_value% %_unixtime% | \\domain\dfs\bin\foo$\nc graphite.domain 2003 -w1 Reproducing and maintaining this folder on a large number of servers/vm's is not desirable. Is there a way to allow Windows Server 2008 to run these tools? If so, can this be enabled via GPO or in a fashion that can be scripted during automated builds? Edit: The commands/tools do work just fine, when run from local drives. Edit2: Wget example: d:\scripts\helpers>z:\bin\wget http://www.google.com SYSTEM_WGETRC = c:/progra~1/wget/etc/wgetrc syswgetrc = z:/etc/wgetrc --2011-04-11 00:32:15-- http://www.google.com/ Resolving www.google.com... failed: Host not found. z:\bin\wget: unable to resolve host address `www.google.com' wget can neither use DNS to resolve the IP nor can it use HTTP if provided an IP directly. Edit3: The problem seems to be tied to DFS/DFS shares. Tools run correctly from other normal windows-server file-shares. They also run correctly when run directly from the file-servers behind the DFS. They only fail when we attempt to run them from the DFS UNC path or mapped drives.

• Force request to miss cache but still store the response

  - by Tom Marthenal

  I have a slow web app that I've placed Varnish in front of. All of the pages are static (they don't vary for a different user), but they need to be updated every 5 minutes so they contain recent data. I have a simple script (wget --mirror) that crawls the entire website every 15 minutes. Each crawl takes about 5 minutes. The point of the crawl is to update every page in the Varnish cache so that a user never has to wait for the page to generate (since all pages have been generated recently thanks to the spider). The timeline looks like this: 00:00:00: Cache flushed 00:00:00: Spider starts crawling to update cache with new pages 00:05:00: Spider finishes crawling, all pages are updated until 1:15 A request that comes in between 0:00:00 and 0:05:00 might hit a page that hasn't been updated yet, and will be forced to wait a few seconds for a response. This isn't acceptable. What I'd like to do is, perhaps using some VCL magic, always foward requests from the spider to the backend, but still store the response in the cache. This way, a user will never have to wait for a page to generate since there is no 5-minute window in which parts of the cache are empty (except perhaps at server startup). How can I do this?

• (Win7) Gets stuck with ~1% CPU. Especially with multithreading

  - by meow

  Windows 7 32 bit, up to date, Intel i7 860. (For some reason the company runs 32bit Windows everywhere.) I tried to update all motherboard drivers etc. as far as possible. I have a performance issue with a machine which appears in connection with multithreading (or so I think). As an example (and where I most often see it, but it appears on other programs as well): ProteoWizard is a file conversion tool for mass spectrometry files. I can add a list of files and it will attempt to process up to 8 files in parallel (quadcore x 2 threads/core). If I choose 1 to 6 files, I start the process and it goes straight through. If I have =7 files in the queue, conversion goes to ~20%, then gets stuck for 15 seconds, then continues again, always in "chunks" of a few % before getting stuck again. During the time the process is stuck, CPU is at 1%. RAM is not limiting, it is maybe at 70% or so and not going up. I don't get the same problem on other, even slower machines. The computer gets also stuck at 1% CPU doing nothing on other occasions, but for multithreading it is most frequent. Where should I look for the problem?

• How to kill ostensibly immortal process?

  - by DeeDee

  I had some huge file transfers operating on an NFS mount. The server on which the mount point resided was carelessly rebooted, and now the server from which these large transfers were initiated seems to be bogged down by them. If I run top, I see the following: The first thing I tried was to run kill with each the -1 -2 -9 and -15 flags, and each of the process ids shown above in turn. This allowed me to proceed, but didn't kill the processes. The next thing I attempted was to reboot the server, but neither reboot nor shutdown -r now worked. When I ran shutdown -r now the standard broadcast message was sent out, but the sever did not reboot. I confirmed this by looking at the server uptime, which was 25 days. So now I'm a little stuck. I'm running these commands as root. EDIT: Here's another interesting tidbit: In top, I don't see that any other processes are using more than a fraction of a percent of memory or more than 5% of CPU. EDIT 2: output of /var/log/messages

• Why doesn't SSHFS let me look into a mounted directory?

  - by Jan

  I use SSHFS to mount a directory on a remote server. There is a user xxx on client and server. UID and GID are identical on both boxes. I use sshfs -o kernel_cache -o auto_cache -o reconnect -o compression=no \ -o cache_timeout=600 -o ServerAliveInterval=15 \ [email protected]:/mnt/content /home/xxx/path_to/content to mount the directory on the remote server.

• Force delivery retry without restarting the SMTP Service on Windows Server 2008 R2

  - by Mathias R. Jessen

  I have a Windows Server 2008 R2 box hosting 3 virtual SMTP servers; vSMTP01, vSMTP02 and vSMTP03. The first two are configured to deliver all messages to dedicated smarthosts, while the last is set to just deliver the messages on its own. All other delivery settings are as default ----(vSMTP01)-----> {SMARTHST01} / ----Inbound mail--->---SMTPSRV01---[----(vSMTP02)-----> {SMARTHST02} \ ----(vSMTP03)-----> { Internet } Now I want to take SMARTHST01 out for maintenance, but I don't want to reject submissions to vSMTP01 while doing so, so I just let it continue running. When SMARTHST01 is no longer responding, vSMTP01 queues the messages and wait for the first retry interval to pass (15 minutes). So far so good. Let's say SMARTHST01 gets online again after 20 minutes. The first interval has passed, and I'll have to wait another 25 minutes for the second retry interval to pass. If I stop and start the SMTP Service (Services.msc - Simple Mail Transfer Protocol service - Stop), the server will retry all deliveries, but that would cause a service interruption for ALL virtual SMTP servers on the machine, which is highly undesirable. How can I manually force vSMTP01 to retry delivery of all queued messages without interrupting the service of vSMTP02 and vSMTP03?

• Port mirroring on multiple switches

  - by Matt

  So here is the deal, I have a server on switch A where port 3 is monitoring traffic for most of the ports on switch A. However I have other users on switch B that needs to have port 3 on switch A monitor as well. Is this possible? I have been reading about rspan but doesnt seem to work. Switch A: monitor session 1 source interface fast0/1 - 2 monitor session 1 source interface fast0/4 - 46 monitor session 1 destination interface fast0/3 (this works great for switch A, I need a solution to get switch B to also have some ports sent to port 3 on switch A for monitoring.) Onxx, All the traffic on switch A is fine, there will be about 10-15 ports on switch B that I need to send to fa0/3 on switch A as the destination. I have the switches connected with a ethernet cable with a trunk port on both switches on port 48 on switch B and A and port 47 on A connects to our sonicwall. So I am assuming they are daisy chained? What if I did the following: Switch A monitor session 1 source interface fast0/1 - 2 monitor session 1 source interface fast0/4 - 46 monitor session 1 destination interface fast0/3 Put all of the ports on vlan 10 because I made an rspan vlan 10 On switch B monitor the ports I need will say 1-10 monitor session 1 source interface fast0/1 - 10 monitor session 1 destination remote vlan 10 as a prerequisite I would have created vlan 10 as a rspan vlan on switch B. Switch A Monitor session 1 destination remote vlan 10 Would this work? By the way I am working with cisco catalyst 3560 switches.

• TortoiseSVN client slows Explorer to a crawl in Windows XP running in Parallels

  - by Cory Larson

  I thought I'd make my first SuperUser question relatively simple, though it's the kind of question that may not get many responses as I'm not directly involved with the issue. A colleague does his development in Windows XP running in Parallels on his Mac. We've just migrated our VSS repository to SVN, and we've gone with TortoiseSVN as our client of choice with the Ankhsvn plugin for Visual Studio. On his XP instance, after installing TortoiseSVN, browsing through folders using Explorer is extremely slow; about 15 - 30 seconds before the contents of the next folder displays. It's the slowest when opening My Computer. Once he reaches a folder that contains the working content of an SVN project, Explorer behaves quickly again as expected. It seems that TortoiseSVN may be spending a bunch of time searching subfolders for stuff so it can do its icon-overlay thing, but that's just a guess. I've used TortoiseSVN for years on both XP and Vista on far less powerful machines without any issues with Explorer, so I'm attributing the slowness to it being run in a VM, though that may not be the actual issue. So has anyone encountered similar performance issues, and/or know of a fix? Keep in mind that any requests to make changes to his configuration will need to be communicated and thus my response time might be slow. Thanks everyone!

• Windows 7 Explorer: how to show total size of all files in current folder?

  - by matt wilkie

  In Windows XP Explorer one can turn on Status Bar which shows, among other things, the total size of all the files in the current folder, or if the cumulative size of the selected files. How do I get the same at-a-glance information in Windows 7? Selecting files doesn't count as it stops after 15 files, and it's rare that I'm concerned about total size with that few files (it's pretty easy to estimate in my head). thanks. UPDATE: Information derived from the context menu (select r-click properties) isn't "at a glance", and not as smooth as selecting files and clicking the details link at the bottom in any case. Thank you for fleshing out more of the available routes though. Yes Q19232 is similar to this one, though it is not a duplicate. That question is about looking for easy free-space on disk stats and this one is easy used-space by contents of this folder stats. The answer for both is the same though. You can't! Hopefully someone will figure how to get this lost feature back with a shell extension or something.

• What to do about old MacBook

  - by John

  I have a White MacBook version 10.5.8. I accidentally dropped it and about an inch of the most right side of the screen is blacked out. I can't see the clock and Trash Can because of this. I checked how much it would cost to repair, and the cost of repairing is a flat rate of $300. I thought that was kind of expensive, like a third of the cost of the MacBook itself. accidentally dropping a notebook is something that would happen sooner or later, so I think getting a Lenovo is the best. I ended up getting a MacBook pro 15 inch, but do you think it's worth the money to fix my old MacBook? I even saw some used MacBooks available on Ebay for about $400. Anyways I don't know what to do with it. I do like its screen and keyboard better than the MacBook Pro ones, because the screen is less glare-y and the keyboard is more crisp and fun to type on, and its more wieldy when I'm using it while lying down.

• Log backups "stalling" on SQL 2008?

  - by MattK

  I have interited a box running SQL Server 2008 and Windows 2003, and have had a few events where largeish (35GB) log backups "stall", both before and after the installation of SQL 2008 SP1. The server log ships to a standby, so regular log backups are taken at 15 minute intervals. However, after an index reorg causes the log to grow to about 35GB (on a DB with about 17GB of data), the next log backup runs to ~95% completion, then seems to stop. The process shows as suspended, with a wait state of BACKUPIO. CPU, read, and write activity on the SPID also does not change, and the process stays in this state for hours, when normally a backup of this size should complete in about 20 minutes. This server has a single RAID-1 volume, thus the source database files and destination backup files are on the same volume. However, I cannot determine if another process is blocking the backup. The backup SPID cannot be killed, and the only way to terminate the log backup and clear the lock on the backup file is to cycle the SQL Server service. There was one event where the backup terminated completely, with an error that another process had locked the backup file, but no details about what that process was. Can anyone suggest a cause or diagnostic process to this situation?

• What hardware would I need (approx) to run ESXi server?

  - by mr.b

  Hi, I am considering to purchase off-the-shelf commodity hardware in order to build server that will host virtual machines using ESXi server. Intended purpose for this server is NOT mission critical tasks. It will have to run perhaps 20-50 Windows XP/Vista/7 virtual machines (in total, but closer to 20 figure). Each guest would have to have 1-2 GB of ram, and probably two-three times more disk space than guest OS needs with clean install and all updates applied (that would be around 6-8 GB for XP, and i believe closer to 10-15 for win7). Those guests will act as a test ground for a new product that is network management software, thus guests will idle most of their time once initially loaded, but if I give them some task to complete, they should be able to perform reasonably well. Now, from what I have learned... CPU is usually not much of an issue (6 cores would do it), memory should not be lacking, but doesn't have to be sum of all guests, because of overcommitment... That leads me to IO, which is, as it seems, the bottleneck. Since I have very little experience with ESXi (and ESX, too) server, I'd like to ask: How much memory could I save by overcommitment, and how does it affect performance? Is 6-core cpu enough to run above described system? Would it be possible to run entire server off two (or even one) SSD drives (to host system virtual disks, with few additional HDDs (2-3) in RAID 0 to be used as secondary storage? I read somewhere that ESXi allows having something like "master image", essentially virtual machine that is "deployed" many times, so that disk space can be saved by having only differences stored by specific guests, instead of copying around whole virtual disks. Is this true, and how can this help me? Are there any other things I need to take into consideration when building this off-the-shelf solution? I should probably mention here that I'm fully aware of issues like SPOF regarding power supply, raid 0, etc, but since it's only a testing ground and not a production system, it's not so important for me. Thanks, B.
