Strip size for MegaRAID Veeam backup target

Post by Daniel S » Aug 09, 2018 4:45 am

I am setting up a backup copy job offsite target repository server.

It will be running Win 2016 and ReFS file system with 64k block size. (Had previous issues with Veeam server running out of memory when using 4k ReFS block size.)

Server has 16x 12TB physical disks. I am setting up a 15-disk RAID6 with one hot spare. RAID controller is LSI MegaRAID.

What “Strip Size” should I select in the MegaRAID configuration? 64KB is default, but options range from 8 KB to 1 MB.

Yes, 128 or 256. The numbers come from the fact that Veeam uses 1MB blocks by default, which usually compress 2x or more.
