[Veritas-bu] Tape SAN + Data SAN
2005-06-08 06:35:53
We do both, in different SANs.
We would now always use separate tape and disk HBA ports, as mentioned by
someone else, you cannot set the driver settings you need for tape on a
port used for disk and vice-versa.
We have tape SANs mostly for organisational reasons, not technical. It
happens where we have several separate SAN islands for disk - maybe
because one is windows, another UNIX (reflecting support or ownership
boundaries, no technical reason to separate them). We then have a
single-fabric tape SAN, which the servers in the other SANs link to using
a dedicated tape HBA port. Folk are every reluctant to merge stable
production SANs, so we have a lot of SAN islands.
So in summary, you can use a tape SAN to front a shared tape library or
set of tape libraries, and use it from several SANs that you may have an
cannot merge. If you have a green field, avoid SAN islands from the
outset.

[Veritas-bu] Tape SAN + Data SAN
We are in the process of buying a STK tape library with LTO (Fiber)
drives. I have two options.
1) use the existing SAN infrastructure to connect the tape drives. I
don't have to buy any extra switches as I have plenty of available
ports.
or
2) buy extra switches.
I would prefer to go with option 2. My question is , anyone using the
existing SAN by mixing the tape libraries and the disk arrays ?
TIA
