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

Famous quotes containing the words product and/or details:
“Out of the thousand writers huffing and puffing through movieland there are scarcely fifty men and women of wit or talent. The rest of the fraternity is deadwood. Yet, in a curious way, there is not much difference between the product of a good writer and a bad one. They both have to toe the same mark.”
—Ben Hecht (1893–1964)
“Working women today are trying to achieve in the work world what men have achieved all along—but men have always had the help of a woman at home who took care of all the other details of living! Today the working woman is also that woman at home, and without support services in the workplace and a respect for the work women do within and outside the home, the attempt to do both is taking its toll—on women, on men, and on our children.”
—Jeanne Elium (20th century)
