QStar Data Director is a storage management application
that builds upon the features and functionality of
their Hierarchical Storage Management application,
QStar HSM,
by adding the ability to replicate data to another
device at another physical location in real time,
with full
failover and recovery in the event of a system failure.
By providing data replication to an optical jukebox
or tape library at remote locations, QStar Data Director
meets the requirements for data center operations requiring
24 x 7 availability. Additionally, QStar Data Director
automatically satisfies regulatory requirements for
storing a second copy of data at an off-site location,
eliminating the need to duplicate data at the production
site and manually ship optical platters or backup tapes
to another site.
QStar Data Director is recommended for the following
data storage applications:
Regulatory
Compliance
Using Qstar Data Director with an Optical
jukebox or Tape Library to store data on non-erasable,
non-rewriteable media types such as Magneto-Optical
and Ultra Density Optical, or LTO and AIT WORM
tape, in order to comply with regulatory requirements
for data retention.
Disaster Recovery
Using Qstar Data Director with an Optical jukebox
or Tape Library to store data at primary and
secondary locations with automatic failover
and recovery in the event of a system failure
or an actual disaster. Additionally, scheduled
maintenance can be performed by intentionally
shutting down the optical jukebox or tape library
at either location, thus initiating a planned
failover to the alternate site.
Data Archiving
Using Qstar Data Director with a DVD jukebox,
Optical jukebox, or Tape Library with secure,
reliable, write-once media types such as CD-R,
DVD-R, Magneto-Optical, and Ultra Density Optical,
or LTO and AIT tapes, for long-term storage
of corporate data, while replicating that data
at a secondary data center.
Highlights of QStar Data Director include all
of the highlights of QStar HSM plus
the following:
- Data Mirroring – Continuously
performed at a transactional level, data files
on the primary
and secondary volume
sets are always exactly duplicated. The volume
sets may be in different optical jukeboxes or tape
libraries
and can be geographically located anywhere on
a corporate Wide-Area-Network.
- Hot Standby – If
the primary volume becomes unavailable, read and
write requests will still
be processed from
the secondary site, eliminating data loss
and productivity decreases during the period of
downtime.
- Automatic Re-synchronization – When
the unavailable volume set becomes available
again,
new data is automatically
synchronized back to the alternate volume,
ensuring that both volumes are returned to a replicated
status.
- Load Balancing – When the amount
of requests exceeds the throughput capability
of the primary
optical jukebox,
the secondary optical jukebox will assist
with the delivery of those requests, thus maintaining
fast
access to data
during peak periods.
