I'm working on turning our 10gb cards and L2Arc, looking to see what others have done.
I have two systems, both with 64gb ram, Intel 750 NVE SSD (400GB) for L2Arc, 24 7200rpm 2TB drives running mirrored Vdevs.
Using HBA with matching firmware.
One server has a chelsios 320 10GB nic, the other has an Intel X520 10GB Nic.
Any suggestions on tuning the 10gb nics and the l2arc.
I've played around with the default tuning options and i've played around with some options i've found in research. From what i've read for L2arc you need to set the max read and burst to be around 90% of the write speed of your ssd, which in my case max write is 900MB/s so i've set it to 800MB/s.
I'm not getting really great write speeds though, it's kind of odd, my disks only show writing at 10MB/s but read speeds were working great!
Just looking to see what others are doing as I work on tuning today.
