Hello all from the frigid north of Alaska.
Start off by saying I am very familiar with Linux, but very new to BSD.
Currently we just deployed older servers for FreeNAS 9.1 that are identical except the drive configuration. Both of these machines are barely putting out 2-10MB/s over iSCSI. Machine configs below:
Xeon 5110 @ 1.6GHZ
8GB RAM
Intel(R) PRO/1000 (x2)
Machine 1:
ATA Hitachi HDP72502 A52A (250G 10k RPM)(x15)
- RAIDZ1 5 Drives 1 Spare
- RAIDZ1 9 Drives
Machine 2:
2TB Seagate 7200RPM (x8)
- 2 RAIDZ1 3 drives 1 spare
I can understand the machine 2 running very slow because of the memory constraint, but the first machine should have enough power to at least push ~50MB/s over iSCSI hooked up to a gigabit switch right?
Maybe I underestimate how much memory ZFS uses but I thought the second machine would at least do 30 MB/s.
Where can I start troubleshooting (correctly)? I've lost my mind trying to figure this out already for the last couple of days.
Edit: IPerf Result of machine 1 to the iscsi target.
Looking into machine 2 further - network is only doing 18 Mbit on both interfaces (2 different subnets) (1 crossover direct and one through a switch)
