Hello! If somebody could help me with a couple of questions in making a best choice for constructing a private cloud?
First of all, let me describe our setup:
I have 2 x node IBM System X 3550 M4 servers
and directly attached via fiber to them IBM V3700 storage (no fiber switch).
The software we have is a bunch of Windows Server 2012 Standard licenses.
Now what i want is to create a proper private cloud from all of this. With the guest cluster of VMs, on which i need to put a workload like SQL server, file server, and some proprietary services. After making a bunch of tests, i encountered a couple of problems so if you could advice on them it would be very nice:
1) As far as i understand, if i do use Server 2012 for VM hosting nodes, i could put only the VMs system drives on CSV volume (for seamless live migration) and for the guest cluster shared storage i'm stuck with iSCSI, am i right? Due to not having fiber switch i can't create virtual fibre adapter, and i can't use CSV for this as that ability appeared only in Server 2012 R2.
So the question is, is there some performance tricks and tips for that scenario? Because in VM's i have sort ofpoor IO perfomance - about 30/40MBps for writing single large file. On the hosting machine, for example, it would be about 150MBps for same scenario.
2) Would it be a good solution to use free Hyper-V Server 2012 R2 as the node hypervisor and use all mine Server 2012 licenses for VMs? As far as i understand then i could use CSV for guest cluster shared storage and the perfomance would be much nicer? What bad consequences could be to this choice?
3) The strange little quirk: when i setup host operation system, be it 2012 Server or 2012 R2 Hyper-v Server, i have avery, very long response frombcdedit. It's like 30 seconds or even more to enum the bcd store - and its a clean new installation. I'm in fear that it's a symptom of some deep configuration problem. How can i troubleshoot this issue? Any suggestions?
Thanks in advance!
