You can either have just 1 card that you will need to remove from the machine with the hardware problem and place into another server or in our case we just got 2 cards and we can configure 2 separate machines to boot off the same lun. You just need to make sure that they are not trying to do it at the same time. Only one machine should be up on one lun at a time.

Boot another server..with the same 4004 card, right?

We are testing the Qlogic 4004 card and it works well. It's pretty easy to setup. You have it point to a lun and then boot off a CD and install Windows on that new iSCSI drive.
I personally think it's a great way to get much higer availability without the added complexities of a full cluster. We have spare servers
standby.
With iSCSI booting, if we run into hardware problem, the operator can shutdown the server, boot another one in place and be up and running in less than 5 minutes.

not many cards do that. Qlogic has one, but the demo I saw (in late 2004) was too painful to configure. Its not ready for primetime I think. -G

What card is the most supported/liked for booting a diskless workstation via iSCSI these days?
And second, how would you go about migrating a disk booting PC, to an iSCSI booting one?
