Actually from SAN disk to TSM client, then from TSM client to SAN Tape (or
disk with SANergy) storage - twice across the SAN. Some variety of
Serverless backup is promised in TSM 5.x next year.

OK, I can accept that : it means that data transfers twice over the SAN :
from disk to server and from disk to SAN
tape storage, wright ?

Regarding your 4th bullet, there is no Server Less backup as yet. In all
cases the data must be passed through a server between the SAN disk storage
and the SAN tape storage.

Hello,
I will soon implement my first TSM Server on a SAN network.
The SAN is connected with a MA8000 storage server, 5 NT clients, and 1 Sun
Unix server
Each machine has local disk + san-attached storage and will use TDP for
oracle to make backups
(data on the MA8000).
I read that a backup/archive of regular files is also possible since TSM
4.2.
Now, is it correct that with LAN-Free backup :
- I can't use diskpools (on the SAN), with migration (next
storage pool)
to the tapelibrary, over the SAN ?
- You always make a "direct connection" from the backup
client to the
storage device which takes the backup
(tape). So data transfers twice through the SAN-switch ?
>From the
MA8000 storage server to the client
(storage agent) and then, from the client to the tape
library ?
- The maximum number of concurrent clientbackups is limited
to the number
of drives in the library('s) ?
Because we can't use a SAN diskpool as destination the
number of mount
points is limited to the number of
drives ? (disk has unlimited number of mountpoints)
- If I want to do Serverless backup / use SAN diskpools I
need Sanergy ?
Can you give me any advices concerning LAN-Free / Serverless backup ?
Thank you for your help.
