I'm restructuring our companies storage and virtualization systems and came up with a new setup. Hope to hear your comments about it and have some questions:
VM Storage (VS):
1x SYS-2028R-E1CR24L
2x Intel® Xeon® Processor E5-2623 v3 (10M Cache, 3.00 GHz)
2x 16GB LRDIMM DDR4-2133, ECC
3x M1015
8x Samsung SSD PM853T (Mirror)
Backup Storage (BS):
1x Supermicro SC826E16-R500LPB (X9SRL-F)
1x Xeon E5-2603
1x 24 GB DDR3, ECC
12x WD Red 3 TB (Mirror)
1x Intel SSD 750 (SLOG) (if required)
1x Intel SSD 750 (L2ARC) (if required, yes I know more RAM needed as well)
External Backup (EB):
1x SYS-6048R-E1CR24L
2x Intel® Xeon® Processor E5-2623 v3 (10M Cache, 3.00 GHz)
2x 16GB LRDIMM DDR4-2133, ECC
1x M1015
12x 4 TB HDD (RaidZ2)
The VS will offer shared storage via NFS to the virtualization hosts (not listed above). We will start with 8 out of 24 slots to have some reserve for future growth (and to keep the budget on track :)
The BS on the other hand should offer SMB shares for network drives (User files etc.). This way I can offer fast SSD-based virtualization with much Random access and HDD-based file services which are more sequential and don't have to be this fast.
Furthermore will BS serve as a backup system for the VS in case it breaks. Hence I plan to replicate the SSD pool on the HDD pool of BS. Of course this would be much slower, but in case of system failure we would be up running (or better walking) in a short time frame.
As VS and BS will be in one rack I planned an additional external backup system (EB) which will be used to collect replications of VS and BS (and again could be used to mitigate hardware failures of the primary systems) and is physically separated.
In case you are wondering why BS uses so old parts compared to the VS and EB system, it simply is an existing server which is young enough to be repurposed.
a) Does this system make sense? Do you see any pitfalls?
b) Is it possible to use the LSI 3008 integrated in the Supermicro boards?
I have seen jgreco using a system with the 3108 chips.
c) Does it make a difference to us 8 mirrored drives with 1 vdev or 4 vdevs?
Adding new drives later on would presumably be done in 2 drive batches.
d) Can i mix drives in a mirrored setup for future expandability?
e) The 10GBit X540 Intel cards are supported by Freenas, aren't they?
f) Memory too low? (I think I know the answer...)
