2x hyper-v plus switch plus san
Hi guys, we've just had our hardware arrive for our new hyper-v environment, I was just wondering if people could check over what i'm going to do- and make any suggestions - not relating to the vm's themselves but to the actual configuration of hyper-v the servers, san and switches
2 x Dell Poweredge R610 - 2 x x5650 processor (6 cores each - 2.66ghz)
32gb ram (ddr3 1333mhz
2x 4port nics totalling 8ports one broadcom one intel
2 mirrored drives (not that important)
Dell MD3200i - dual controllers (4ports per controller) 12x 450gb 15k drives
each server will have 4 ports to the san switch and 4 ports to the main network (link aggr)
the san will have all 8 ports to the san switch (link aggr)
the SAN environment will operate on a different ip range to our main network, so we will have 172.16.*.*(main network) and 172.15.*.* (SAN Network)
have installed Server 2008R2 with Hyper-V installed as a role on both machines which will connect to an ISCSI LUN to store VM's. We will also be using SCVMM to manage this environment.
any feedback would be much appreciated.

It really depends on if you intend to use failover clustering. If you are you might need a small rethink.
We use failover clustering and use 10 ports per production server. The extra two are for heartbeat of failover and hyper-v management.
SCVMM also needs to be part of a domain, which means your hyper-v servers need to be in a domain (member servers at least).

Spec looks fine, the only thing I would possibly do if you have the budget is change the dlink switch for a Cisco as they allow much more fine tuning of the link aggregation. I'm a big fan of HP Procurve switches, but have really found their limitations on link agg when using for virtualisation. Have tried other switches as well, same sort of problems. A poor performing switch between your SAN and VM hosts can really stuff things up.

yes, we already run a 2003R2 domain which is gradually going to be moved up to 2k8r2 although domain controllers will stay physical.
also with scvmm, should it be installed onto one of the hyper-v servers or a seperate server? I dont have the documentation with me at the moment as i'm at home, but I guess thats something to consider.
oh and we have reached the ends of our budget having just had to replace our core switch (8+ years old) with a brand new swanky 3com unit 4800g sfp I think.
