Hello,
I am in the final stages of selecting components for Hyper-V 2012 cluster and SAN, I am interested in people's opinions on what the best tweaks for improved performance.
SAN will be 8G FC (eg 3PAR 7400 / Compellent SC8000 / NetApp VNX 5500) with 30-40 Tier-1 disks, 20-30 Tier-2 disks, possible some SSD.
Servers will be 2 CPU (eg E5-2680), 256GB Memory (16x16 1600Mhz), 3 x 146 15K in RAID-1 + spare, 2 x single port 8Gb HBA, 4 x 10GB NIC, 4 x 1GB NIC
Introducing 10Gb switching for east-west traffic that will most likely be connected to 6509-E core using multiple 1Gbps.
Where would you spend money if you wanted to increase performance ?
SSD for the SAN ?
10Gbps from rack switching to 6509 core ?
Upgrade CPU to E5-2690 ?
Fusion IO ?
One vendor suggested having SSD for the Hyper-V OS drives.
I do realise I have provided little details on the workload, assume typical small business, 1000 users, 60 guests, file, print, exchange, sql, sharepoint. Backup is on seperate hardware using DAS.
Thanks
