Hi,
I have recently purchased a FAS2020 with the following:
FAS2020A,12x300GB,Base,R5
DS14MK2 SHLF,14.0TB SATA,QS,R5
The purpose is to run VMs over iSCSI.
I have run basic setup and configured Active/Active clustering.
For the storage design, I believe I have the following options, but would appreciate any feedback on how others have configured their aggregates and volumes:
Design Option 1:
This creates new aggregates without changing the factory settings.
| Controller 1 | Controller 2 |
---|
aggr0 | 3 x 300GB disks R5 - container for root volume + 1 hot spare | 3 x 300GB disks R5 - container for root volume + 1 hot spare |
aggr1 | Remaining 300GB disks RAID DP + 1 hot spare (shared?) | |
aggr2 | | 13 x 1TB disks RAID DP + 1 hot spare |
Design Option 2:
Due to the fact that 8 of 12 15K disks get used by the system after install, leaving around 2 disks of usable space from the 300GB 15K shelf, I have been considering the following:
| Controller 1 | Controller 2 |
---|
aggr0 | 7 x 300GB disks R5 - container for root volume + 1 hot spare | 3 x 300GB disks R5 - container for root volume + 1 hot spare |
aggr1 | | 13 x 1TB disks RAID DP + 1 hot spare |
Questions for each option:
Can the hot spare be shared by the aggregates for the same speed disk?
If Controller 1 goes offline, will Controller 2 take over the storage presentation?
Any other advice or design to consider?
