Hi everyone , this is my first time posting here so please be gentle.
I am looking at building an new 2012 R2 with Hyper V setup , everything has to be HP hardware .
2x HyperV 2012 R2 servers running 20-30 VMs . These will be dual 6 core xeons with 128gb of ram
2x 2012 R2 back end storage servers running SMB 3.0 shares , connected to the front end VM servers with multiple 10gb ethernet connections. Not sure on the hardware requirements for these servers so advice helpful .
2x SAS 6gb external enclosure for each storage server . Probably HP d2600 enclosures
A couple of questions :
What is the best way to achieve high availability and redundancy in this setup ? Should I use replica's or a HV cluster ?
What is the best way to ensure redundancy of the storage back ends ? File share clustering?
Would the performance of the SAS enclosure be fast enough ? What kind of drives would be suitable for this? Would 7.2k SAS drives be enough or would we need faster ? What would be the best raid setup ? Initially there would be 12 drives expanding to 24 .
Would a mix of fast SAS or SSD and SATA be more efficient ?
thanks in advance , any help appreciated
