Hi Folks,
Considering Starwind vSan for a high performance shared Postgre SQL and MS SQL volume, and I'm wondering what kind of performance I should expect with the following 3 Node (3 way mirror) configuration. All 3 nodes are identical hardware.
OS: Win 2019 Server
CPU: x2 Xeon Gold 6138
RAM: 512GB ECC DDR4-2400
Storage Network: Mellanox ConnectX-3 dual port 40GbE, Direct connections (no switch)
Storage option 1: 1x Intel Optane 905P U.2 960GB per node (No RAID, just NVME to Starwind)
-OR-
Storage option 2: 2x Intel Optane 905P U.2 960GB per node (Storage Spaces Mirrored... concerned a bit about random 4k Q1T1 perf though)
-OR-
Storage option 3: 2x Intel Optane 905P U.2 960GB per node (Storage Spaces Simple... concerned a bit about random 4k Q1T1 perf though)
-OR-
Storage option 4: 2x Intel Optane 905P U.2 960GB per node (VROC RAID 0, if supported by Starwind... will probably cut 4k Q1T1 perf down to 1/2 of drive perf potential)
-OR-
Storage option 5: 2x Intel Optane 905P U.2 960GB per node (VROC RAID 1, if supported by Starwind... will probably cut 4k Q1T1 perf down to 1/3 of drive perf potential)
So, I'm leaning towards Storage option 1 since these Optane drives have a DWPD of 10, and this should give the best random 4k Q1T1 performance. I'm just curious, though, how this would perform with Starwind on top of it.
Any input would be great! Thanks!
