• Memory usage increased on ESXi 4.1 for ESX 4.0

  Hi all

  Recently, we migrated about 130 virtual machines to a Cluster of U2 ESX 4.0 to esxi 4.1 u1 cluster and noticed that the memory usage is very high on the hosts compared to 4.0.

  The band u2 4.0 was 255GB of RAM between 9 guests and the new cluster has 355 GB of ram between 7 hosts.

  use of the memory of the 4.0 u2 was about 60-70% and now on 4.1, on the use of 90%. Can someone please explain this. It is more difficult to understand that there are 100GB more RAM available on the new cluster, but its use all this.

  ESX 4.0 host u2 were HP BL460 G1 - 32 GB each

  ESXi 4.1 u1 are HP BL460 G6 - 48 GB each.

  Thank you

  According to me, IT ' was all about GST (Transparent Page Sharing) and your new generation of CPU. This phenomenon is independent of the version of vmkernel. Let me explain briefly,

  New processor generation, such as Nehalem, have a feature called hardware support memory management unit, which includes a buffer cache called TLB (Translation Lookaside Buffer). I will not dive into the details but if vmkernel detects that your CPU have this kind of functionality, he decides to use pages (2 MB) memory instead of partial memory (4 KB) pages and also do not use GST as long as a restraint on resources of memory occurs. This is why you have a higher memory usage that you expect to see.

  To work around the problem (not a best practice but it is necessary), you can force vmkernel to work with small pages and trigger the GST. There is an advanced for this setting.

• Electrodes for ESX 3.5 Update 4 (build 153875, early release 2009/03/30)

  I update document to build our ESX company for new servers and one of the steps-after installing ESX 3.5 U4- is to get the latest patches of 'CRITICISM' http://support.vmware.com/selfsupport/download/

  We do not update - manager

  not yet-

  don't ask.  We are always pleased with esxupdate.  In any case, I went to http://support.vmware.com/selfsupport/download/ and unfortunately, I'm a little confused when it comes to the stuff of ESX 3.5.  But after some trial and error on the use of this site, I think I've found the following is true:

  1. do not take into account ALL the patches dated on 30/03/2009, as those who are already installed with the image ISO of ESX 3.5 U4.  This has been confirmed by "esxupdate query.  It shows these all listed/installed.  I guess it makes sense, since the data on the release of ESX 3.5 U4 / 153875 Build is just that - 30/03/2009.

  2. list all patches for ESX 3.5, all classifications and sort by date.  This will show the patches AFTER 30/03/2009, which are available AFTER the ESX 3.5 U4 ONLY really put patches / Build 153875 iso image has been released for download.   This really translates into the listing of all available patches FROM 153875 build is actually released.  As of today, there are 10 patches with April 2009 dates and 5 patches with may 2009 dates.

  I'm sure that many of you know already all this, but since I'm new to 3.5 built and have not used this site 'free service' for some time, it took me some time to "understand it".  I am also curious to know if someone told comments.

  If you are looking to document a procedure, your best bet would be to include:

  Check the release ISO date before starting the installation.

  Based on the release date control patches that were released after release date. This means that all the patches would be new which is not part of the iso image.

  I hope this helps.

• How to create ESXi cluster or team two ESXi servers to avoid VMHA of HA?

  Hello world

  The scene is, I have two machines Dell 2950 and want to install ESXi U4 or ESXi 4 on both machines.  The requirement is that I have to install Windows 2 K 8 Server as guest and installing MS SQL Server inside on HOST1 (for example). This will be a production server.  Now I want the APP or database on this to be highly available.  I can mirror whatever say who's here to HOST1 on another machine HOST2 and keep it to fail the course in time REAL.  OR can I team or bonds or group these two hosts using local storage (data warehouses) and without the use of third-party storage (I can't afford VMHA, because it involves SAN and SAN or NAS in turn need fail on).

  In simple terms, the creation of ESXi cluster or team two ESXi servers to avoid VMHA of HA?

  TIA for all your contributions.

  -Nadine

  VnonCP

  Try Openfiler or FreeNas?

  Both will allow you to use the local storage on your ESX as an NFS share.

  Problem is that if your ESX host plant... you have a data store that is dead.

• Can I downgrade my Satellite Pro P200 for Windows XP?

  Hello

  I bought my Satellite Pro P200 (PSPB7E) a week ago and I love it. I have an unused XP license, so I would like to downgrade.

  Is this problem? I don't see xp for a Chicony webcam drivers or the HD-DVD player.
  I'd really appreciate some feedback. There must be someone out there who has tried to do.

  Thank you in advance!

  Hello

  Of course you can downgrade the satellite Pro P200 for Windows XP.

  When installing XP, you need to install the Intel Storage Manager. It is a SATA driver that is needed to activate the HARD disk.

  Regarding the webcam driver.
  I checked the page European driver of Toshiba and the Chicony webcam driver is certainly available.

  The HD DVD driver is not necessary because the Windows XP must use an own ODD driver.

• Can I downgrade Windows 8 64-bit for Windows 7 64-bit?

  Can I downgrade Windows 8 64-bit for Windows 7 64-bit?

  And also my drivers continue to operate?

  I have only one installation of Windows 7 disk and want to make sure that I could use it incase if my computer goes down / gets corrupted / ect. Since I formatted acccidently my OEM drive when I take away a lot of partitions, I did.

  My computer:

  Model: HP 2000 Notebook PC

  Model No.: C2N26UA #ABA

  OS: 8 64-bit Windows

  Additional info: my computer came with Windows 8 64-bit pre-installed.

  Hello:

  First of all, make your game of W8 recovery discs before proceeding.

  All the W7 x 64 drivers of this Associates model should work on yours.

  http://h20000.www2.HP.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=5275377&prodTypeId=321957&prodSeriesId=5259212&swLang=13&TaskID=135&swEnvOID=4063#11360

  The driver is missing (and is for any laptop AMD) and it's the chipset driver that installs the SMBus Controller and the USB 3.0 controller.

  You should download and install this driver first and then restart. First download listed is what you need.

• Change the path information for ESX ESXi hosts to access

  Hello all! I hope you guys can help me.

  I have about 47 hosts that I need to change it Round Robin storage path information. If I make the change in vCenter and restart the host it again changing fixed. So, I thought that I should change it to the level of the host through esxicli.

  I have about twice as many LUNS of the Hitachi SAN. I'd like to see if it is possible to make the change in all areas, in some way, or I need to make the change by host? Also, is there anything that I need to change sides San so that it works or not.

  I saw this VMware KB: modification of path information for ESX/ESXi hosts to access and assume that it is the best plan? But did not know of all put into custody, if necessary, that everyone ran to when doing this?

  You will need to make the change by the host and the KB you'll find is the right method.

• Script - missing and hotfixes installed for ESX and ESXi

  Can I have the script i.e. missing and hotfixes installed for ESX and ESXi using the CLI power only? out put should be csv format

  You reset the content of the table $Results on each iteration of the baseline.

  Try like this

  $Results = @()
  foreach($esx in Get-VMHost) {
    foreach($baseline in (Get-Compliance -Entity $esx -Detailed | where {$_.Status -eq "NotCompliant"})){
      $Results += $baseline.CompliantPatches |    Select @{N="Host";E={$esx.Name}},    @{N="Status";E={"Compliant"}},    @{N="Baseline";E={$baseline.Baseline.Name}},Name,ReleaseDate,IdByVendor,    @{N="KB";E={(Select-String "(?http://[\w|\.|/]*\w{1})" -InputObject $_.Description).Matches[0].Groups['url'].Value}}
  
      $Results += $baseline.NotCompliantPatches |    Select @{N="Host";E={$esx.Name}},    @{N="Status";E={"NotCompliant"}},    @{N="Baseline";E={$baseline.Baseline.Name}},Name,ReleaseDate,IdByVendor,    @{N="KB";E={(Select-String "(?http://[\w|\.|/]*\w{1})" -InputObject $_.Description).Matches[0].Groups['url'].Value}}
    }
  }
  $Results
  

  It will give the installed and lack of patches which are defined in the non-compliant baslines related to the ESXi host.

  If you want to see all the lines, also the most consistent, omit the Where clause on the base line (foreach) loop.

• VMware ESXi for ESX 4

  Hello

  Someone know if can I upgrade my ESX 3i (3.5.0) to VMware vSphere (ESX 4)?

  Thank you

  You can't spend of ESX ESXi... ESX to ESX and ESXi for ESXi only... At least, not as an 'upgrade '. Provided that your host is on the HCL for ESX/ESXi 4 (u1 as well), then you can install it. This will be a facility of cleaning/charges however, wiping the LUN which ESX is installed on.

  You might want to stay on ESXi however, given that ESX is pretty much going to end with the 4.x releases (at least this is what I mean)... The released product in 2011 only is not available in two flavors, just ESXi...

  The ESX CLI, consider using the device of vMA and element vSphere CLI on your vCenter Server installation. You can also install the PowerCLI element to win these CLI scripting options.
