Hi All,
I have a HP ML350P Gen8 server to upgrade and would like an opinion on the best way to configure the storage array. I am picking up from some else's start/mistakes so some of it may not be the best.
Current Setup:
HP ML350P
2x Xeon E5-2609 2.4Ghz
24GB Ram (2x8 2x4)
P420i 512MB with 3x 1TB Sata 7.2K in Raid 5 = 2TB Raid 5
Server 2012 Datacenter Edition.
4x Hyper-V VM's
DC - 19GB VHDX (127GB Limit) - DC and Shadow Protect.
File - 23GB VHDX (127GB Limit) and 500GB VHD - High Priority File Store and Shadow Protect. Industry DB stored Here. Shadow Protect.
Mail - 41GB VHDX (127GB Limit) and 500GB VHD - Exchange Only and Shadow Protect.
Remote - 31GB VHDX (127GB Limit) - Office 2010, User Access, Industry App Front End and Shadow Protect.
Currently they have approx 40 users with about 15 concurrent users. They would like to increase this to as much as 45 concurrent and 120 users in total.
I am currently testing their industry application for Ram usage per person. The application is a private DB backed application but has a similar IO load to SQL.
I would like to;
Upgrade Ram to something like 64GB (may be less once the figures are ready)
Change to SAS HDD's with either 1 array pool or as many needed.
Convert all VHDX to VHD
Tune the Hyper-V settings as currently the CPU is about 5% at even the busy periods with the current CPU allocations. Also Ram is way under utilized in the current config.
Can you guys please recommend the array setup you would look to use?
-2x 146GB 15K Raid-1 for Host and a Raid-10 for VM storage?
-Separate Arrays for each VM? (this would prob limit us to mirror sets)
-1 big Raid-10 pool with host and VM's?
Please let me know if I am missing any info.
Thank you.
