Hi,
we use the storage to host a lot of VMs.
Currently we have the following setup:
MSA2052 configured with only Pool A
1x Raid 10 disk group #1 with 16 SAS drives
1x Raid 10 disk group #2 with 4 SAS drives
1x SSD performance tier Raid 1 with 2 SSD drives
2x global hotspares
1 Volume using the above setup
We bought two expansion shelves with 14 SAS drives and 2 SSD drives each.
How should it be set up? I was assuming to do the following:
- Delete performance tier Raid 1 and recreate it with all 6 SSDs using Raid 5.
- Create additional Raid10 disk group #3 with 7 SAS drives of shelf 2 and 7 SAS drives of shelf 3 = total 14 SAS drives - all in POOL A (does striping the group over both selves makes sense at this point?)
- Create additional Raid10 disk group #4 with 7 SAS drives of shelf 2 and 7 SAS drives of shelf 3 = total 14 SAS drives - all in POOL A (does striping the group over both selves makes sense at this point?)
- expand existing Volume to new maximum size
Will this work? Is there a better (more performing) option possible? I am also not sure if putting some groups in Pool B will work as we want to use only one big Volume for everything to gain performance from all the disks.
Any recommendation is much appreciated.
Thanks
