Thx a lot for your Answer. But I am not sure about the meaning of your Message.
Probably my bad English.

1. Whats wrong with 90-95 MB/Sec Tranfer Speed over one Gigabit Connection?
I think 125 MB/Sec is the highest possible Speed. Right?

2. I wrote that iSCSI work as expected - only Replication Speed is not acceptable.
Network Speed (see 1.) can not be the Reason for that.

3. May be that HP is not the first Choise for OPEN-E - but should I throw away my
HP Hardware???

So, where are the helpful hints?
