I'm having a problem with a Dell MD3200i and our new Dell T710 virtual server -
it works, but performance is absolutely abysmal. Here's the
details....
Server is a T710, 4 onboard nics + a 4 port Intel Server NIC. Its
running the latest update of ESXi 4.1 - right now it has 6 hosts on it,
going to be 10 total (most are lightly loaded special purpose servers).
Server is connected to the SAN by 4 cables direct from the 4 port Intel
Server NIC to the 4 ports on the management controller
We have 4
drives (2TB SAS) in the SAN - not my first choice - but what the
customer wanted. Array is set up as a RAID-10. We have 3 logical
volumes - 2 TB, 1 TB, and 750 GB. Each is formatted as a VMFS
datastore.
I followed the instructions in the Dell whitepaper for
setting up the MD3200 with ESX 4.1 and it doesn't appear we have
multpathing working correctly. The VCenter Client is only showing 6
paths usable - should be 12 total (3x volumes * 4 network cards).
I've
gone through the docs a handful of times, can't find anything that
strikes me as an obvious problem. Below is the output of some of the
commands in the documentation - if anything else would be helpful let me
know. I feel like i'm running in to a brick wall here, any advice
would be great!
Thanks in advance....
