Good evening.
I have a box with the following configuration. I would like to know what kind of performance I should be getting.
I've been playing with my setup, but could not get the results I was hoping and aiming for.
Dell R720xd.
2x E5-2640 0 2.5GHz (3.0GHz)
128GB ECC RDIMM DDR3
24x 300GB 10K SAS drives (Single drive in HD Tune ~ 170MB R&WR)
2x200GB Enterprise Toshiba SSDs (mirrored SLOG thru FreeNAS) (rear flex bay)
1x400GB Intel 750 AIC (L2ARC)
Intel 10Gbit x520 card
LSi 9207-8i on the latest firmware (updated a couple of days ago)
Internal RAID1 SD for OS (9.10.2 Update1)
Dell's N4032F SFP+ switch
Dell R710 with 4x SSDs in RAID 0 with the same Intel x520 card (Client, to testing the performance) 1500/1400 R/WR
Here's the situation.
I've tried 2 scenarios:
1. RAID 10. 12 mirrors. Gives 500MB/s write and 1GB/s read ( I guess it's capped with 10Gbit connection. Yet not aggregated)
2. RAID Z2. 6 drive Z2 x 4. Gives 400MB/s write and the same 1GB/s read.
I'd like to improve the write throughput. How would I achieve this.
If somebody has a similar or close setup - please help.
