Product Details
TSM maintains a relational database (limit 534GB through TSM v5.5, 2TB with TSM v6.2+) and recovery log (aka transaction log, limit 13 GB through TSM v5.5, 128GB with TSM v6.1+) for logging, configuration, statistical information, and object metadata. v5.5 DB pages are always 4KB, and partitions every 4MB. Single row inserts only. On average, 20GB of space is consumed for every 25 million objects. Shallow directory structures use less TSM DB space than deeper paths. This database may generally be queried via an emulated SQL-98 compliant interface, or through undocumented SHOW, CREATE or DELETE commands.
Actual user data is managed via a cascading hierarchy of storage media (Primary Storage Pools) presented as raw devices (UNIX), filesystem containers (Windows and Linux), streaming tape or optical media. Additionally, emulated tape from a Virtual Tape Library or EMC Centera WORM archival device are supported. Duplicate copies (Backupsets or Copy Storage Pools) of any subset of data may be created on sequential media for redundancy or off-site management.
The 5.5 release of the TSM Server is supported on AIX, HP-UX, Linux, Solaris, Windows Server, and z/OS. The current 5.5 release of the TSM Client is supported on NetWare, Mac OS, AIX, HP-UX, Linux, z/OS, Solaris, and Windows 32/64-bit.
The 6.1 release of the TSM Server is supported on AIX, HP-UX, Linux, Solaris, and Windows Server. The current 6.1 release of the TSM Client is supported on the same operating systems as 5.5. TSM 6.3 was released in October 21, 2011

“To [secure] to each labourer the whole product of his labour, or as nearly as possible, is a most worthy object of any good government.”
—Abraham Lincoln (1809–1865)
“Different persons growing up in the same language are like different bushes trimmed and trained to take the shape of identical elephants. The anatomical details of twigs and branches will fulfill the elephantine form differently from bush to bush, but the overall outward results are alike.”
—Willard Van Orman Quine (b. 1908)
