Hi,
Indeed the 3 disks per vdev (raidz2) seems a bad idea...but it's the
system i have now.
Regarding the performance...let's assume that a bonnie++ benchmark
could go to 200 mg/s in. The possibility of getting the same values
(or near) in a zfs send / zfs receive is just a matter of putting ,
let's say a 10gbE card between both systems?
I have the impression that benchmarks are always synthetic,
therefore live/production environments behave quite differently.
Again, it might be just me, but with 1gb link being able to
replicate 2 servers with a average speed above 60 mb/s does seems
quite good. However, like i said i would like to know other results
from other guys...
Don't forget to factor in your transport mechanism. If you're using
ssh to pipe the send/recv data your overall speed may end up being CPU
bound since I think that ssh will be single threaded so even on a
multicore system, you'll only be able to consume one core and here raw
clock speed will make difference.
Cheers,
Erik
