Best practice for configuring virtual drive on UCS

Answered Question

Hi,


I have two C210 M2 Server with LSI 6G MegaRAID 9261-8i Card with 10 hard drives of each 135GB. When I tried the automatic selection for the RAID configuration, the system has created one virtual drive with RAID 6. My concern is what the best practice to configure virtual drive? Is it RAID 1 and RAID5 or all in one drive with RAID6? Any help will be appreciated.


Thanks.

Since you are planning to have UC apps on the server, Voice applications have specified their recommendations here.

I believe your C210 server specs could be matching TRC #1,  where you need to have


RAID 1  - First two HDDs for VMware

RAID 5  - Remaining 8 HDDs as datastore for virtual machines ( CUCM and CUC )

Hello,

Just curious, can you please let us know how did you create automatic RAID configuration ? Did you use Server Configuration Utility ?


The application determines disk IO requirements and would influence RAID configuration too. The best practice must consider application requirements.

Hi Padramas,


Thanks for your reply. I did use the configuration wizard by pressing Ctrl-H during the boot process. I will install Unified Communication Manager 8.6 and Unity connection 8.0. The user size might grow to 1000-1500 users. May be in future, I might install UCCX. Considering this configuration settings, what would be the best practice. Appreciate your help.


Thanks.
