PERC H700 cause windows unable to load

Hi,

I have dell poweredge R610 with Samsung 860 EVO ( RAID 10 ) with PERC H700. I google and I found that some of end-users are using it as Production Level.

Samsung 860 EVO doesnt support Power-Loss Protection (PLP) but I believe H700 does.

Yesterday, one of our server having issue for the power failure and those redundant power supply are totally off. When I power on the server, I was unable to boot the windows and the bootmgr are totally corrupted.

I have questions for the PERC H700. How I can prevent this thing happened by using Samsung 860 EVO ?

I believe that there is some setting I need to do with H700 isnt it? I have BBU for teh H700 and it is working fine.

The production server was totally corrupted and I have to reformat back my windows server 2012 R2.

 

Please assist. Thanks

    I can't speak to the Samsung drive, but the H700 uses it's battery to power a memory cache. To make sure that cache is being used, the card needs to be in Write back mode, not write through. The easiest place to change confirm this setting would be in OpenManage Server Administrator, once you have a functional OS again.

    As for the Samsung drive, it's an unsupported SSD, so you may run into issues. Someone in the community may have experience with this SSD and controller combination, though.

    Hy Dylan,

    I already change from the Write through to Write Back

    Based on this screenshot ( http://prntscr.com/oxzdbs ) can you elaborate to me, which setting is MOST EFFICIENT, LESS HASSLE, SUPER FAST WRITING/READS , HIGH IOPS for PERC H700 running on RAID 10 for hyper-v ( Windows Server 2012 R2 )

    Unfortunately, I wouldn't be able to make a recommendation for you on this. You want read ahead and write back enabled for speed. Disk caching can depend on your storage. You can certainly try both and see which works better for you, though.
