Help me to understand and please correct if I am wrong: 1. As far as I know from v4.1 and what I read in v4.2 docs, the storage agent allows LAN-free (-->) DATA (<--) movement. Meta-data goes through LAN from client to server and sits in the DB. The server mounts the tape volume, (I do not know who exactly does tape positioning), and storage agent (limited functionality server code) writes backup data through SAN to the tape. If needed server dismounts volume, mounts new one and the operation continues. So if we thing about the storage pool data it goes straight from client/agent to volume - no server involvement except for tape mount/dismount. It does not have to go through the server.
2. SAN library sharing through SAN Data Gateway (or SAN Data Gateway Router) is available since v3.7 between servers, enhanced in v4.1 to allow storage agent (not server) also to access the tapes but only for Windows Agent and in v4.2 is additionally enhanced providing storage agents on AIX and Solaris. So this was available long time ago (sorry I cannot say when v4.1 was announced and am too lazy to check). 3. There is a possibility to share sequential volumes which are not tapes but FILE devclass through SANergy. Did anybody tested/used this? Is anybody on this list using SANergy? Does this mean that a storage agent can backup to shared FILE volumes (best theoretical backup time - both disks and FC) and later TSM server can perform storage pool backup and migration? 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?

That will imply 3rd party SCSI copy functionality, which I haven't seen any indication they have incorporated to TSM. The physical data will still have to go through the TSM server, within the SAN environment, before it gets put in a storage pool.
