Nothing at all for Win2k HyperSCSI.
For iSCSI I tried the initiators I could find: Cisco and IBM.
Both are specifically designed to work with their hardware targets and use older revs. of the spec. (rel. 0.8 ??)
I was trying to use the Intel target.
As I recall, the IBM initiator did not connect at all.
The Cisco attempted, but failed in the parameter negotiation that takes place at the start of a iSCSI session.
Since iSCSI was just approved a few weeks ago, I'm hoping that Microsoft will come out with a Win2K driver shortly.
If they do, I expect that someone will come out with a Linux target that supports it.
BTW: Have you tried Window UNIX Services 3.0

I haven't, but I'm hopeful that it will create "local" drives somehow. (I very much doubt it, but I'm hopeful).
BTW2: In a pure Windows environment, HPs Storage Replicator does exactly what you want, but it is pricey (IIRC $10K)
