The parameters are:

Can i be sure that the IO transfer is 2MB or .... ?
Use iostat or another tool (DTrace iosnoop.d) to see for sure.
Note that these are upper limits...
I wants to lign up my Sun ST6140 for optimal performance and therefore needs to
know the transfer size.
OK, but since this is zfs-discuss, I presume you know that ZFS uses a
maximum block size of 128kBytes.
