you will hear here different answers as every SAN admin has their own
preferences there. Also it depends on several other unknown factors to
decide a SAN hardware vendor plattform.
Generally you should carefull with the sizing of your storage subsystem as
this is mostly one of the critical areas where performance can be degraded
for all running VMs. golden rule here is = as much as possible spindles :-)
Before you get an correct answer to your question you need to know the
workload (I/O) requirements of all your 1000VMs and also the right
distrubution. 40 VM per host is generally no problem for Hyper-V when you
take care of the performance for SAN connection, I would prefer 10GBit if
ISCSI and min. multiple 8GBit SAN FC adapters. The general decision between
Fibre Channel and ISCSI SAN environments should also be worked out. Do you
have a SAN network already in place ? if yes, what are your SAN switches
capable, 2-4 or 8GBit ? If not, ISCSI with 10GBit possible ?
NetApp is fully supported by Hyper-V and it really depends if you would
require all the featureset from Netapp as you also pay for each license.
I personally have have also very good experience with ISCSI boxes like
Equalogic (Dell) or HP Lefthand .... With the falling price barometer in
10GBit segment ISCSI is becoming really in scope also for high workload
scenarios like yours.
Hope that helps a bit
