Storage Area Networks for Linux? 6
angelo asks:
"Many of us have heard the buzz (on the radio of all places) about Storage Area Networks, or SANs. They are a method of accessing a common drive system, backing up information over a second network, and collaborating a server farm. My question is this: Can you connect a Linux box to a SAN network? If so, which SAN products support Linux connection and administration? Do all channel cards have drivers, some of them, or is it "in the works?"

There are two problems that I see:
First, as the earlier poster mentioned, last time I checked linux assigns /dev/sda to the first scsi device it finds, /dev/sdb to the second, etc. I've never seen what linux does when, for instance, scsi id 5=/dev/sda and you add a device with id 3 and rescan the bus. Personally, I'd love to know what happens. It would be nice if there could be a switch from the way things are to a system more like (as I recall) Solaris uses which is not sequential, but definitive, i.e. incorporating into the device name the system bus/adapter/adapter bus/scsi ID/LUN. Of course that would be a pain for all of us that are used to the old way.
The second problem with the Vicom's is that you can only configure them from an NT box. In general this isn't too much of a problem, since you only set it up once, but if you really hate NT, it may be a problem.
They've got some interesting stuff. They are here [vicom.com].
