Hey,
Sorry for this revisiting this thread late. What exactly is sync writes ? Do
you mean synchronous writes or a app calling fsync() after every write ?

mail storage server type workload will not benifit with a
ZIL as proven by zilstat and a postmark workload.
Iam guessing Sun 7310/7410 will behave the same way with this type of workload.
Do the logzillas/readzillas do anything special on these boxes ?
TIA

Just to clarify : Does iSCSI traffic from a Solaris iSCSI initiator to a third
party target go through ZIL ?

http
e a big file on /iftraid0/fs and watch `iostat -xnz
2` i dont see any stats for c8t4d0 nor does the write performance improves.
I have not formatted either c9t9d0 or c8t4d0. What am i missing ?
TIA
