I’ve been researching different ways to increase speeds for iSCSI on TrueNAS Scale. Most of my Google-Fu just shows information about TrueNAS Core or older versions.
Basic Hardware for TrueNAS Scale:
- 2x Xeon Quad Cores
- 64GB RAM
- 6x 4TB Hard Drives (SAS 12gbps) in a RAID Z2 config
Currently getting about 100MB/s Reads & 140MB/s writes
ZFS cache shows about 30GB in use.
Any way to increase throughput? I was looking to see maybe adding 2x SSDs as a SLOG? Would that help at all?
Anyone else run into this issue before or something similar? How’d you fix it? Any opinions?
