Hi all
I have a really stupid question (well two of them). On ESX box (V2.5 and V3). Will a defective CPU or a defective memory module cause the OS (ESX) to abend. We are using HP dl585 with 4 dual cores and 64 gb ram per box.
It could very well be that either part that goes defective (cpu or memory module) will cause the hardware to seize. Should this be the case, can someone confirm.
Also I understand that under VI2.5 if cpu 0 goes, then thats it the box is down, but what about if one of the other cpus goes down? Does the same thing also apply to VI3.
thanks

According to this document from RTFM Education any failed CPU will cause the entire server to abend.
www.rtfm-ed.co.uk/docs/vmwdocs/ESX2.5-Update.doc
When I talked to my VMware rep to come up with a server standard they recommended we use memory mirroring to protect against a failed memory module causing the ESX server to crash. This was under 2.5 but I would be willing to bet it would still have the same effect in VI3.

I think your question applies universally to any operating system environment.
If a functional Operating System component is in memory on a failed stick or a running critical Operating System thread is on a CPU that goes kaput, thats it.
Thanks guys, very much appreciate the answers.

Interesting thought....has the VMkernel or will it lose connection through the virtualisation layer to a CPU?
Vmware course states any CPU failing will cause a PSOD due to the way it distributes CPU load for VM's.
We had a DL-585 G1 running 35 VMs crash due to a failed CPU voltage regulator module.
Was not a pleasant experience.
Moving forward VI3's HA will help mitigate this issue.

Well, anything in the x86 space. There are systems ($$$$$) that can survive a CPU failure, but you won't be running VMware on them
heres a bit of wishful thinking, IBM z Series, running an i386 64 bit emulation in each Lpar, which is running VMware ESX.
And whos gona let you do that to test and fiddle with unless you work for Sungard Tom?
I have seen a product that uses old DEC technology with physical Windows, apparently it dosnt support Virtualised platforms due to CPU operations being what it syncronises between hosts.
nice wish

It was just wishful thinking. I'll just power up the IBM in the garage. lol

Yes ... and then you wake up all sweat all of a sudden !

Massimo, have you no ambition :smileygrin:
