At the heart of ILM: HSMS – Hierarchical Storage Management System
Success in business means quick and secure access to business critical data. While IT-infrastructures are becoming faster
there are trends threatening the quick, secure and economic use of data: The data explosion, rising costs of storage and its ever
increasing management complexity, the slow evolution of procedures and their lacking automation, the rising demands on data
availability and security, the proliferation of incompatible data islands. Therefore complexity reduction is a prime target. Trends
in the storage field show where we are heading for: Centralized data management, storage configuration simplification via
virtualization and variant reduction, ILM – i.e. automation of data management according to usage profiles and according to
economic criteria, data encryption for more security , data mirroring for new levels of data availability and shorter
backup/restore-windows via disk-to-disk-to-tape-concepts (d2d2t).
HSMS is an effective, central Storage Management System which
reduces the complexity of the management of data on external
peripherals, which automizes the data management and optimally
fits with the BS2000/OSD-platform. Add ons like the automatic
media management (MAREN), the automatic robot control
(ROBAR), accelerated data encryption (cryptobox) or backup for
other platforms (HSMS-server) make HSMS into the scalable
kernel for the information lifecycle management in BS2000-
environments.
HSMS supports the BS2000 data center administrator both in the
management of large amounts of data, which arise in data backup
and archival, and in optimizing the use of external storage devices.
Equally, ordinary users can also use the HSMS functions on files
assigned to their own user ID.
HSMS – Functional description
Today’s external storage media can be ranked according to a
distinct hierarchical structure in terms of price/ performance
ratio, i.e. magnetic disks and tape cartridges.
This external storage hierarchy can be managed with the
following basic and specialized features of HSMS.
Basic features :
„ Migration
Migration is used to export unused data to a low-cost
hierarchical level, from where it is retrieved automatically
for processing when accessed. HSMS provides this
function for local BS2000-systems.
„ Data backup
Backup is a system service that supports the logging of
backup copies for use in data recovery in the event of data
loss (e.g. disk crashes).
„ Long-term archiving
Archival is a user function supporting the long-term storage
of data in order to meet legal requirements (obligation to
preserve records).This function is offered in local HSMS
operation as well as via the backup server functionality.
Special features:
Shadow archives: An automatic duplication function for save
files is available for creating copies during backups and for
long-term archiving. For this purpose, a new type of archive is
created, called a shadow archive. Each time a backup is
written to an archive for which there is a shadow archive, a
copy can be created automatically by HSMS and entered in
the shadow archive.
Database backup: HSMS enables the user to run online
backups of the database files of the BS2000/OSD database
systems SESAM/SQL-Server, UDS/SQL and ORACLE. Read
and write accesses can continue to be performed to the
database files while the backup is being taken. The
administrator can collect the changes occurring during this
time, also back them up with HSMS and apply them when the
backup is being loaded. With SESAM/SQL-Server, UDS/SQL
and ORACLE, the user can independently use HSMS to back
up the database files. The SESAM/SQL-Server database
system provides a separate interface for administration of the
backups and uses HSMS internally.
