Hello,
We have been running the TSM Server on z/OS, backing up
Windows/Solaris/Linux clients. Our backup media has been a StorageTek
Powderhorn Tape Silo, emulating IBM 3490E drives (tape capacity 2GB). Within
the year the silo will be upgraded to emulate IBM 3590 drives (tape capacity
60GB).
Clients have been dissatisfied with the throughput of the TSM backups.
Typically, the aggregate transfer rates have ranged between 1MB and 3MB/sec.
That's not good when you want, for example, to backup an Exchange database over
100GB in size.
Anyway, there is a project spawning here to possibly bring in some SAN
boxes, like the EMC Clarion models. The idea would be to somehow directly
backup to the SANs, or have a tape silo Fibre Channel connected directly to the
SAN.
My first question is, is there a way for the TSM Server on z/OS to talk
directly to the SAN boxes? Or would the SAN have to be emulated to z/OS to look
like some type of IBM mainframe tape device (3480/3490/3590/whatever)?
