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)?
