Poor performance with EVA4400 and OpenVMS 8.4 using QLogic ISP2422
our new environment with FATA-Disks in a EVA4400 shows a throughput of about 300 mbit/s
(using copy, backup and Oracle/Rdb database access). I think that is to less and there is a problem somewhere.
For the test a simple connection form the VMS-System to the switch and form the switch to the EVA is used. Speed is checked with evaperf and the monitor utility on the Switch. There are no errors on the Fibre Channel.
Any ideas ?

Re: Poor performance with EVA4400 and OpenVMS 8.4 using QLogic ISP2422
Is that true that the EVA4400 has that bad performance ? I expected to see about 30-50 MByte/s without write cache and 5-10 times more using wtcm.
From what I see it makes no sense to install FC-Disks and to use 4GB FC-Interfaces on the hosts.
Is it possible that something is misconfigured in the EVA ?
