I have 2 SSA drawers.
1st drawer is:
7133-020 fully loaded with 4GB disk. This drawer is mirrored front to back,
and at the adapter level.
2nd drawer is:
7133-D40 fully loaded with 36GB disk. This drawer will be raid 5.
This server has 2 SSA Enhanced RAID Adapters 6215 (4N). The adapters do not
have fast write cache.
I know I will not get the full performance from the D40 on this old
adapter.
I want to mirror at the adapter level. Is this a valid configuration?
Drawer 1 7133-020
8 to A2 ssa0
9 to A1 ssa0
1 to A1 ssa1
16 to A2 ssa1
Drawer 2 7133-D40
8 to B2 ssa0
9 to B1 ssa0
1 to B2 ssa1
16 to B1 ssa1
I do not have any experience with RAID5. I read where you can put 16 disk
in one raid array. I have two possibilities:
(1) 15 disk in one array, plus one hot spare
(2) 2 arrays with 7 disks each, plus a hot spare for each array.
