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?
Maybe, or a 2x1G LAG would me more cost effective (and easier to
check!). The only way to know for sure is to measure. I managed to get
slightly better transfers by enabling jumbo frames.
I have the impression that benchmarks are always synthetic, therefore
live/production environments behave quite differently.
Very true, especially in the black arts of storage management!
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...
As I said, the results are typical for a 1G link. Don't forget you are
measuring full copies, incremental replications may well be
significantly slower.
