Maybe I should have just said Ditto.

It's not a technology limitation, it's an OS limitation: Microsoft does not
support arbitrated access by more than one server to a single logical drive.
So while you could make a logical drive on the RA4100 visible to both
systems (actually, if you connected an RA4100 to the SAN you'd have to work
to prevent the logical drive from being seen by all systems - by default all
systems would try to mount it), Windows would quickly trash it as both
systems would at some point try to make conflicting updates to critical NTFS
data structures, corrupting the drive beyond repair.

So if UNC virtual directories aren't an option, file replication is about
the only other choice.

Subject: Using SAN technology


I have a client requiring multiple host access to a logical drive defined on
a Compaq RA4100 and my problem is allowing multiple host access to the
logical drive once isit is formatted by Windows. I have tried the Tivoli
SanErgy product but essentially I need to have two servers view the drive as
a local drive so I can use multiple IIS servers to access the same web
content. The solution seems to be out of the realms of possibility at the
moment as I an not allowed to use UNC share names to access the web content
for various reasons and thus the home directory of each web site must refer
to a drive letter and folder. I do not think I can get this to work under
current technology but has anyone else come across such a problem? Thanks in
advance from Paul Reynolds
