In theory the 3rd party copy will allow the disk to send data directly to
the tape without going through the TSM server. This is done using new
SCSI XCOPY commands. All the work is done under the supervision of the
backup server (or perhaps a client via a storage agent), so TSM knows what
has happened.
The IBM 2108 SDG already has some 3rd party capability, and will probably
be the first device to control the 3rd party copy. This capability IS NOT
in current TSM, and functionality for future versions has not been
announced, of course.
Think about how fast disk pool migration could be with 3rd party copy...

Sorry for being less informed but what this 3rd party copy functionality
does and again how this feature will help to let the server know what the
client have done?

> 4. What is this server-less operation? Is this an already implemented
feature in v4.2.1 (new feature in maintenance release ?!?) or just
something planned to be implemented in v5.1 (or later) ? How the
server-less backup will mark volumes if it does not have any path to
notify the server DB? Or this would be some kind of standalone solution,
i.e. server + local client (+TDP for Apps) with reduced
capabilities/features?
It is my understanding that Serverless backup will be release in 5.1. I
believe it will only work with SAN Routers and Gateways which have the
SCSI 3rd Party copy functionality built-in.
