Looks like Adaptec is now PMC-Sierra. I didn't know that and I'm sure a lot of other people aren't aware of this as well. The fact that adaptec, a staple of raid controllers is listed as another company is mind boggling. Why mess around with such a well known name.Greetings from Adaptec by PMC!Sorry for the confusion, []! Our cards are listed under PMC-Sierra in the "Brand Name" column on the compatibility search. Per the compatibility list, our 6405 card is compatible with the following ESX versions:ESXi 5.0 U1ESXi 5.0ESX / ESXi 4.1...

Here was someone on the forums trying to storage vmotion out their vms and it would not do anything but it would complete.The user was storage vmotioning the virtual machine to the same datastore.He was attempting to move it from thick to thin.When ever you svmotion a vm to the same datastore it will complete because the vm is already there, even if you attempt to change the disk type.If you look at the image, you can see the svmotion tasks finishes...
Logs don’t persist after reboots but lets check that.That should be for usb installs and autodeploy.Here is a host with a local hard disk:Im going to check the system syslog of my esxi host and see what the 1st item isPress w on your keyboard until you reach the 1st line.W goes up a page in the console logs.This is before the rebootSo the 1st line is 2012-08-28Lets reboot and then see what the first line isWell what do you know, the logs...

There are some interesting things in vsphere 5.1I'm surprised there is a new virtual machine format already. One interesting thing is VMware tools updates without reboots in the future, vi client seems to be on the depreciated path, and vmotion without shared storage?Will have to dive deeper in to the release when more info is out.Virtual machines: New virtual machine format : version 9 New features include support for larger virtual machines, CPU performance counters and virtual shared graphics acceleration...
Why powercli?A lot of what I've seen out there for backing up the host configuration uses VMA or Vcli but I use powercli more consistently as I know a lot of other people do also.Here is the code to backup your esxi host via powercliGet-VMHostFirmware -VMHost $host -BackupConfiguration -DestinationPath C:\DownloadFolder Set-VMHostFirmware -VMHost $Host -Restore -SourcePath c:\bundleToRestore.tgz -HostUser user -HostPassword pass*note: that...

Saw this over at the forumshttp://communities.vmware.com/message/2103207#2103207Someone was unable to get their broadcom pcie card to be recognized by Esxi, even when using the Dell ISO install of esxi.It was avaialble in bios." some servers going out with the PCIE slot disabled"Looks like Dell has been shipping servers with pcie slot turned off so the card wont work even though it is recognized by bios. 12th gen servers now have an ability to disable PCIE slots. And they are disabled apparently by default, even if you order the server ...
Yes but you will need enough disk space for the swap file.Example:Host has 32GB physical ramYet the vm has 64gb allocated to itIf you don’t have enough swap space you get this error:Here 1tb of ram was allocated to the vvm.I don’t have 1tb on the store nor do I have 1tb or ram.So it couldn't power ...

modern versions of the hypervisor show almost no performance difference between thick and thin for 99% of workloads. -mcowgerPasted from <http://communities.vmware.com/message/2100863#2100863> Question : How different is the performance between thick and thin?So I was thinking most cases thin is as good as thick, but thick is for that extra performance bump.But things change a lot so I was looking for some hard data to back it up*This test from planet zorg benchmarks thin vs thick lazy vs thick eagerComparing the latency and iops...

The answer is that the vcneter server is like any other vm and vmotioning it is not a problem.This is a proof of concept that it works.Earlier I also did a POC that storage vmotion (svmotion) also works on the vcenter host.http://sparrowangelstechnology.blogspot.com/2012/07/can-you-storage-vmotion-svmotion-your.htmlHere is the vcenter server on host 2Now its being vmotioned over to host 1Now the server is on host 1 as expec...

For performance you should have a battery backed cache for write back mode, which tells the OS that a write happened before it does because its saved on the cacheIf you use write through mode, you will slow down the array because the os is then waiting for the disks to complete a write before continuing.It might seem that this is obvious but if you are having problems check that out.A user on the vmware forums was experiencing problems with their riad throughput and it was a mis config on the raid.http://communities.vmware.com/message/2090651#2090651A...

Its best to have no snapshots and power off the vm according to vmwarehttp://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004047 But is it possible to increase disk space without powering off the vm?Example: Disk is 35gb and the vm is activeAdding 15 more GB to make a total of 50GBRescanning disks and the extra space shows upYes it is possible to increase a VM's disk space while powered ...
