A cluster for TSM?
1. „No, it's just backup.“
TSM today is a 24x7 application. Continous database log archiving. A bunch of single file restores a day. Do you have service level agreements? Public law specifications.
2. „We have self-made scripts.“
This was very easy with TSM Version 5. But for Version 6? Are the scripts working with 6.2 / 6.3 / 6.4 / 7.1?? Try and error? Ongoing development needed. How many programmers do you have (Vacation? Sick??) Do you speak DB2? What are „Log pinning“, semaphores, IPC, sockets ...?

3. „We have an operating system cluster.“
OS cluster depend extremly on the underlying OS. This is desired. Each OS has its own cluster (HACMP, MSCS, ..) New OS / new patch means: New cluster. OS update = cluster update = downtime. The purpose of an OS Cluster is to cover every application. There is no predefined plugin for each application. Simple ressource monitoring. It is complex, ongoing education is needed. Hard to manage. TSM admin is not able to do this. OS staff <> TSM staff (inconvenient for troubleshooting/updates) Limited design (number of TSM instances / nodes). Complicated license model.
A cluster for TSM?
4. „It's expensive.“
NO!!

Our solution! TSMCluster® extends the standard TSM server and
build a high availability solution for it There is no need for additional cluster software Is part of the IBM Value Advantage Plus program
and an IBM certified solution. Listed on www.ibm.com as partner solution.
…..since 10 years in the market!!

New: Mouse-over information / page timestamp / quicker.Dynamic adaption of drop boxes.

What is the difference?
TSM server „tsm01“IP Alias 10.10.1.21Port 1521
TSM server „tsm02“IP Alias 10.10.1.22Port 1522
TSM server „tsm03“IP Alias 10.10.1.23Port 1523
TSM server „tsm04“IP Alias 10.10.1.24Port 1524
TSM server „tsm05“IP Alias 10.10.1.25Port 1525
Any-to-any concept Multiple TSM server (instances) are running on
multiple machines / VMs (nodes)
= TSM Server/instance is running

What is the difference?
Sensor based TSM control A sensor is like a stethoscope Multiple sensor allows „a view into the
future“ of the TSM Server (failover prediction)
Customizable sensor for the database, logs, DB2, OS etc.
Compares static and dynamic values Sensor changes the cluster behaviour Additional sensor can simply be added
(c) 2015 by eXstor GmbH 1215.08.2015
What is the difference? Sensor are the focus in the new version 5.3 They are stored in a SQL database Graphical/SQL interface to the data They help with:
– Additional measurement of resources– Rating of a node / instance– Problem visualization and determination– „last-minute decisions“– Alerting improvement
