So I've setup my test system. It's a dual quad core system with 2.33
ghz procs and 8GB of RAM. I have 12 2.5" 146 SAS drives connected via
a LSI SAS expander and 1068 hba. For the boot drive, I'm using a 2.5"
sata and I also have a Intel SSD (32GB SLC) which I'm using for ZIL.
Oh - i'm running Express Community Edition snv_113.
Can anyone share some insight on how best to benchmark fs performance?
I usually use iometer, but I can't get dynamo to compile on this
platform.
I see alot of people use iozone, but I don't really understand why
some of the performance numbers exceed the maximum throughput in
theory for 12 SAS disks.
I've configured a single mirrored pool with no hot spares across all 12 disks
# zpool status
pool: datapool1
state: ONLINE
scrub: none requested
config:
