The LAN-Free Storage Agent is a limited function TSM server which is configured as a library client and uses server-to-server communication to coordinate the use of storage resources which are configured to TSM but which are also presented to the storage agent. The TSM architecture makes use of two special-purpose agents. Aside from TSM's UNIX HSM product, only the "Backup" and "Archive" management facilities are accessed through the client API. GPFS provides transparent access to data whether online on disk or migrated to tape by requesting file saves and retrieves from TSM.Īdditionally, many applications provide or are provided with TSM API connections allowing the storage of databases, mail systems, system backups and even arbitrary user data within TSM's repository.
IBM TIVOLI STORAGE MANAGER SOFTWARE
A GPFS filesystem can be simultaneously accessed from multiple servers running Linux, Windows, and AIX by using GPFS filesystem software installed on any of these operating system platforms. IBM General Parallel File System ( GPFS) can use TSM as a storage tier for GPFS' Information Lifecycle Management (ILM) which provides HSM for a GPFS filesystem. These allow migration of data from production disk into one or more of the TSM storage hierarchies while maintaining transparent access to that data by the use of DMAPI or NTFS reparse points. Other data injectors include policy-based hierarchical storage management (HSM) components for AIX, Linux and Windows. Additionally, there is no provision for an incremental archive. This still differs from traditional full/incremental style backup products in that the files are stored separately or in smaller aggregates rather than as a monolithic image. This method generates groupings of objects to be retained as a single unit.

Further, a separate method is provided by the B/A Client which is known as archive (and retrieve). The B/A Client allows backup and restore of data both "selectively" and "incrementally", which is generally known as "Progressive Incremental" or "Incremental Forever", as each unique client+filespace+path+file combination is separately tracked for retention. The most Common data source for TSM is the TSM Client ("TSM Backup/Archive Client" or "B/A Client"). The major components of TSM include: TSM Server, TSM Client, TSM Storage Agent, TSM Data Protector, TSM Operation Center and TSM Administration Center. Tivoli Storage Manager as a system is made up of several different components. On October 21, 2011, TSM 6.3 was released.

The 6.1 release of the TSM Server is supported on AIX, HP-UX, Linux, Solaris, and Windows Server, while the TSM Client is supported on the same operating systems as 5.5. The TSM Client of the same release is supported on NetWare, macOS, AIX, HP-UX, Linux, z/OS, Solaris, and Windows 32/64-bit. The 5.5 release of the TSM Server is supported on AIX, HP-UX, Linux, Solaris, Windows Server, and z/OS. Duplicate copies (Backupsets or Copy Storage Pools) of any subset of data may be created on sequential media for redundancy or off-site management. Additionally, emulated tape from a Virtual Tape Library or EMC Centera WORM archival device is supported. This database may generally be queried via an emulated SQL-98 compliant interface, or through undocumented SHOW, CREATE or DELETE commands.Īctual 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. Shallow directory structures use less TSM DB space than deeper paths. On average, 20GB of space is consumed for every 25 million objects. v5.5 DB pages are always 4KB, and partitions every 4MB. TSM maintains a relational database (limit 534GB through TSM v5.5, 4TB with TSM v6.3.3+) 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. Starting with TSM 6.1, released in May 2009, TSM uses a Db2 instance as its database (thus eliminating the architectural limitations of the previous TSM database). The TSM database (through release 5.5) was a bespoke B+ tree database although the TSM database uses many of the same underlying technologies as IBM's Db2, has a SQL engine (for read-only use), and supports access through ODBC, the database has an architectural limit of approximately 530 GB, and 13 GB of log space.
