UCS - 220 M3 S

Hi All - Few clarification in configuation of Write Policy during Installation of RAID.

We have 8 HDD with 300 GB, Out of which i confifured 2- HDD as RAID - 1 and installed ESXI - 5.0 U1 and remaining 6 HDD as RAID - 5, I would like to know which write Policy i need to choose for both RAID

Set Write Policy to one of the following:

- write back with bbu- if using a RAID card with SuperCap (e.g. RAID-9266CV)

- always write back – if using a RAID card with legacy Battery Back-Up (BBU) instead of SuperCap (e.g. RAID-9266). This option helps prevent a UC application performance impact in the event that the BBU goes into learning mode or the battery dies.

Note  

Whenever possible, use the new RAID cards with SuperCap and make sure the UCS is attached to an Uninterruptible Power Supply (UPS).

Can you please advise.
