a unique disk compression, optimization and vritualization appliance. Any application that stores large amounts of data may
benefit from using DataOptimizer to cut storage costs, improve
performance and ease storage management. DataOptimizer logical
volumes are accessed like regular disks on a SAN and all compression and
decompression operations are totally transparent to the applications.
DataOptimizer is designed to compress large volumes, in a safe and efficient way using Microtal’s
ultra fast SQZ compression.
- 4:1 space savings for
databases. 2.5:1 space saving for regular files.
- DataOptimizer logical
volumes are used like regular disks.
- Supported Operating Systems: Windows, Linux and Unix.
- Frequently modified blocks
are used uncompressed. Compression and defragmentation are done
automatically in the background.
- Hotspot elimination. All
frequently accessed blocks are stored together on the underlying
physical volumes to eliminate multiple hotspots and to improve
- DataOptimizer supports a
combination of fast (expensive) and slow (low cost) disks for optimizing
storage cost/performance. Most applications access routinely 10-20% of
the data, while the rest of the data is hardly ever used. I/O operations
are automatically balanced between all the physical devices in the
volume group using an adaptive algorithm; the smart data placement
algorithm stores frequently accessed blocks on the faster disks while
infrequently used data blocks are stored on the slow disks. Blocks are
automatically migrated from fast to slow media and vice versa based on
their access patterns.
- Offsite storage support. Data centers with limited floor
space may use DataOptimizer to store infrequently used data
on a remote site with little or no performance penalties.
- Thin provisioning: New logical volumes use very little disk space, storage is added
incrementally as needed when data is written, eliminating
the need to pre-allocate large volumes.
- All maintenance operations
may be performed while DataOptimizer is running. During physical
volume move or delete operations, data will be migrated transparently to
other disks without affecting the running applications.
- Volumes, which are not
managed by DataOptimizer, may be attached to optimized volumes. The
original volumes content may be accessed immediately while
the data is automatically migrated and compressed in the
background. When data migration is done, the old volumes may be
freed and reused.
- Plug and play operation: DataOptimizer supports moving disks to different addresses or even to a
different appliance. When new disks are discovered DataOptimizer will
recreate the logical volumes that were stored on these disks.
- I/O pattern trace
capture. These traces can later be filtered, analyzed
or even replayed without the original application in order to optimize
- Built-in hooks for running
user specified commands as a result of events such as, sending email to the
administrator when DataOptimizer runs low on disk space.
- Storage estimator: A
program that estimates the storage savings that may be achieved by using
- 60-80% storage cost reductions.
- Better data reliability.
- Lower energy and cooling expenses.
- Better utilization of Data Center floor space.
- Shorter backup Window.
