So the main problem turned out to be simple: I didn't have write cache enabled on the controller. Before I discovered that I ran the Atto disk benchmark on the storage server itself (no iSCSI, no VMWare -- just direct attached storage. I got the results in the first (a screenshot from Atto). The wri...

I'm beginning to have the same suspicion. I've created a 4GB RAMDisk starwind target and the problem doesn't occur there. I can copy files >2GB with no performance issues -- the copy runs, as it should, at pretty close to wire-speed.

-M.

Using a standard vmware setup to the starwind target (in eval mode), I'm seeing very peculiar behavior. When I copy large files to the iSCSI target (an image file), I get excellent copy performance (near wire-speed over 1GbE) -- right up until the point that about 2GB has been transferred. From that...

I got the adapters working (it was indeed a firewall issue -- I'd forgotten that Windows Server 2008 has separate sets of firewall rules for doman/private/public networks, and my iscsi was running on a private network, not the domain network that I'd opened up. Duh.) The performance of the adapters ...

I'm trying to get a pair of Chelsio N320E-CXA adapters to work for iscsi between a Windows 2008 Server R2 box running the StarWind 5.0 target and a vSphere 4.0 host. Before installing the 10GbE adapters, I verified that a regular GigE connection between the two boxes worked correctly -- the StarWind...
