Re: Tapeless TSM System

Many people are using VTL's (Virtual Tape Libraries). IBM has the TS7510 and
EMC has the CDL. There are also many people using large disk subsystems like
the IBM DS4300 or DS6800 or the EMC Clarion or Symmetric. Then on this disk
subsystems they use TSM's file device class.
In the end using a tapeless solution should require a the TSM server or at
the very least the TSM storage to be in an off site location. My customers
that have removed tape have a multi data center environment. Have have many
with two datacenters. They configure the backups from one datacenter to go to
the other so the data is offsite and thus there is no requirement to rotate
tapes. I have a few customers with three data center design. The production
servers are in two main data centers. Critical servers are GEO clustered. Then
those two data centers backup to the third datacenter.
In a singe datacenter design you should still be using tape because you
should still be taking a copy of your data offsite.

Was wondering if anybody out there has implemented TSM using a tapeless
system? This is something we are considering.
Any insight would be appreciated.
We currently are using TSM version 5.2.2.0 on a Window 2003 server. Using
a STK 9710 tape library.
