A major driver in storage growth is
regulatory compliance. Government
regulations such as Sarbanes-Oxley Act
of 2002, HIPAA, BASEL II and PIPEDA
requires you to retain many files for
extended times and be able to access
them quickly, so deleting files is not an
option. Traditional off-line archives are not
adequate for the task of quick access and
require substantial administrator effort to
manage properly.

Maintaining all files on primary storage
results in unacceptable backup and
recovery windows, in addition it drives
rapid growth of high performance storage
hardware capacity which results in
storage costs spiraling higher.

Solving the Growth

BrightStor HSM allows you to use various
cost-effective storage devices to create a
central secondary storage tier that
provides production servers a virtually
infinite enterprise repository for seldom
accessed data files. BrightStor HSM,
running in the background on a
production server, constantly monitors the
status of its assigned volumes.

When a scheduled or pre-determined
watermark is reached, files are
transparently and automatically migrated
to the secondary storage tier. A pointer to
the migrated file is retained in the
production server’s file system, enabling
quick identification and automated
retrieval of files from the secondary
storage tier anytime that the file contents
is accessed. Users see the file’s directory

quick identification and automated
retrieval of files from the secondary
storage tier anytime that the file contents
is accessed. Users see the file’s directory
entry with all of its original attributes
including its size and security settings and
users are generally unaware that their
files have been migrated, even when
accessing them as the time lag to restore
the file from the secondary tier is nearly
instantaneous.

As much as 90% of files maintained on a
file server are seldom or never accessed.
By migrating these files to a secondary
storage tier, the primary production
storage capacity is drastically reduced.

While new files are continually added to

are migrated to the secondary tier,

With as much as a 20:1 cost differential
between primary storage hardware and
hardware suitable for secondary storage,
the rate of growth in storage cost is
between primary storage hardware and
hardware suitable for secondary storage,
the rate of growth in storage cost is
greatly diminished. If desired, a third tier
of storage can be created with an
automated tape library. This third tier
storage will continue to provide users with
access to their files within minutes.
of storage can be created with an
automated tape library. This third tier
storage will continue to provide users with
access to their files within minutes.
An additional benefit of controlling the
capacity requirements of primary storage
is a substantially smaller backup and
recovery window. Often, primary
production servers are protected with high
performance technology, such as RAID
10, snapshot or replication in order to
manage rapidly changing data. These
technologies are expensive to implement
and maintain. The secondary storage tier
changes only when files are migrated and
can be protected with much simpler tools,
at substantially lower cost, and backup of
the secondary storage tier will not impact
the production environment.

If you are faced with backup windows
interfering with production business,
spiraling storage costs or compliance
pressures, BrightStor HSM can help you
solve these issues.
