Reply to the post "Yes I am a victim of the popular PSOD"


This is a reply to the post http://venthusiast.blogspot.com/2014/05/yes-i-am-victim-of-psod-while-using.html

I have checked this a bit more thoroughly, the difference between E1000 and VMXNet3 Cards are that VMXNet3 is an implementation of paravirtualized driver. Hence it handles the I/O more efficiently. 

The paravirtualization provides specially defined 'hooks' to allow the guest(s) and host to request and acknowledge these tasks, which would otherwise be executed in the virtual domain (where execution performance is worse). A successful paravirtualized platform may allow the virtual machine monitor(VMM) to be simpler (by relocating execution of critical tasks from the virtual domain to the host domain), and/or reduce the overall performance degradation of machine-execution inside the virtual-guest.

Yes I am a victim of PSOD! - while using E1000 Network cards

Last month mysteriously the blade servers keep going down with Management interface going haywire

We have been getting this PSOD time and time again.



Logged a support call with GSS and advised to upgrade the VMware vSphere Platform or replace all E1000 NICs of the virtual machines.

The KB article for the related issue as follows;


With this issue we were forced to upgrade our current VMware Platform.

My next post will be 5.1 to 5.5 upgrade.
