Thanks for that reply.
So just to make sure I have it right, if they make DSS startup in 32-bit mode, they will still be able to access the volume created while in 64-bit mode (I thought this may have been a problem), then boot to iSCSI-R3, and the volume will be there, yes?

I guess I should just go & try it, but it's eaisier to ask you!
Is there any plans for 64-bit iSCSI capability?
Thanks.
