VMWare conversion....

So.... I am going through a VMWare conversion process at iTouchPoint.   This involves converting legacy app, and sometimes legacy servers, to run under VM's.


It's been a learning experience to say the least.



  • Overcommitting memory is fine, so long as you don't end up swapping to a SATA disk :-)
  • OpenFiler as an iSCSI device running 3 SATA drives that are short-stroked will give you amazing performance: we're doing > 4000 IOPS, which is all we needed, I don't quite know what this box is capable of
  • LAN LAN LAN => iPerf is very useful when it comes to figuring out that your LAN stinks!  200MB/*minute* on a 1GB LAN???? Come on!!!
