I would like to get comments on a proposed configuration for a new Hyper-V server. The hardware is existing that will be re-deployed.
Hardware: Dell PowerEdge 2900
Processors: 2x Xenon 5160 3 GHz dual-core
Memory: 16 GB
Storage: 6x 68GB 15k SAS HDD (HDD0-HDD5) 4x 136 GB 15k SAS HDD (HDD6-HDD9) 2x 64 GB SSS (SSD0-SSD1)
OS: Server 2008 R2 Enterprise
VMs: DC1, EXCHANGE1, SQL1, RD1 (Remote Desktop)
Physical OS: on 68 GB RAID 1 volume consisting of HDD0 and HDD1
DC1.vhd: on HDD2
EXCHANGE1.vhd: on HDD3
SQL1.vhd: on HDD4
RD1-SYSTEM.vhd: on HDD5
SQL1-DATA.vhd (90GB) and RD1-DATA.vhd (182 GB) on 272 GB RAID 10 volume consisting of HDD6-HDD9
SSD0-1 could be used instead of HDD4 and HDD5, on the idea that they contain the most active vhds.
Backup for all vhds is 1TB USB HDD.
Would it be preferable to create a 136 GB RAID 10 volume using HDD2-HDD and put DC1.vhd, EXCHANGE1.vhd, SQL1.vhd, and RD1.vhd on it, instead of giving each their own spindle?
