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.
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 )
