Hi,
I would like to build NAS for ESXi datastore, but I'm not sure which configuration would be best for this.
It must be Cisco UCS server, so there is two option for the config:
1. UCS 240M4 with 10x3.5 10TB 7.2k disks + 2x800GB for ZIL and 1x800 Intel p3700 for L2ARC
2. UCS 240M4 with 22x2.5 1.8 TB 10k disks + 2x800GB for ZIL and 1x800 Intel p3700 for L2ARC
For Platform itself it's pretty much the same for both options:
2x 3.40 GHz E5-2643 v4/135W 6C
8x 32GB DDR4-2400-MHz RDIMM/PC4-19200/dual rank
First config with 3.5 drives will have 2.5 times more capacity, but I guess that second config will be better because of more spindles, hence more performance? Also Does it make any sense to use 256g or RAM or 128 should be enough?
Regarding workload, this is storage for virtualisation LAB, so there is no strict requirement for space or performance. It's more like I'm just trying to understand how much 2 time more 2.5 10k disks will be faster than two times less 3.5 7.2k disks.
Thanks.
