Hello Guys
Pls Advise on the below Raid Config for SAS Disks
Disk01 and Disk02 = RAID 1
Disk03 = Hotswap
Disk04,Disk05,Disk06 =RAID 5
Disk 07 = Hotswap for Raid 5
thanks all

Greetings.
That config will work fine.
Assuming that your OS raid 1 mirror are likely smaller disks, you can use a single hot-spare that is the size of your larger raid 5 sized disk, and mark it as global hot-spare, which will kick in for either raid volume when needed.
If you have a BBU/Supercap backed cache module, make sure you enable write-back caching w/good BBU.
Thanks,

If you have questions about general raid terms, please view the raid controller user guide at https://www.cisco.com/c/dam/en/us/td/docs/unified_computing/ucs/3rd-party/lsi/mrsas/userguide_june_2017/pub-005110_DB15-001199-08_2017-06-09_MR-614-SW-UG.pdf and search on write-back or BBU.
Thanks,
