Hello

I've bought 2 Open-E DSS Server 16TB, but before installing this on my servers, I'm evaluating Open-E DSS Lite on my test hardware.
The test hardware are Shuttle PC's, with Marvell 88e8056 PCI-E gigabit network controller, with also a second network card Realtek 8139. The systems are connected to a 3com 3CBLSG24-switch which is divided into 2 vlans, one for the storage (on the Marvell cards) and one for normal access (on the Realtek cards).
I've installed a Open-E DSS Lite on 1 system, a Debian 64-bit system on another system, and Windows 2003 on another system.
iSCSI is working perfectly, with Open-iSCSI or the Microsoft iSCSI client.
BUT the performance seems to be very slow.

On linux:
/dev/sda (local disk)
Timing buffered disk reads: 222 MB in 3.01 seconds = 73.64 MB/sec

/dev/sdb (iscsi disk on open-e):
Timing buffered disk reads: 76 MB in 3.09 seconds = 24.63 MB/sec

This seems to be really disappointing, this is nowhere near Gigabit performance. I've set the jumbo frames to an MTU of 9000 (on both the iscsi and the client machines), but this doesn't seem to help.
I know this is only a test setup, and it's the lite version of the product. What can I do about the performance? Am I doing something wrong?
