PALO ALTO, California, April 29 /PRNewswire/ --

- Highlights differences vs. legacy solutions

Nexenta Systems, Inc., developer of NexentaStor(TM), the leading
enterprise class storage management software taking an open source approach
to market, is pleased to announce the commercial release of NexentaStor
Enterprise v. 1.0.

Current customers of NexentaStor include the University of Michigan
School of Medicine, Motek Entertainment (Netherlands), Ozmo Devices, Stanford
University and many other enterprises and Universities worldwide.

NexentaStor Enterprise Edition is superior to alternatives in at least
five ways:

-- Storage without limits: based upon ZFS, a file system with 128 bit
       addressing and many other capabilities, NexentaStor offers limitless 
       file system sizes and limitless numbers of incremental backups, known 
       as snapshots.
    -- Inherent virtualization: keeping up with rapidly changing storage
       demands with legacy storage solutions is challenging. Storage 
       administrators waste significant time and money adjusting volumes and 
       adding capacity. NexentaStor is built from the ground up on storage 
       virtualization, which makes all storage capacity available to all 
       users and applications. In addition, NexentaStor uses virtualization 
       to improve performance as scale increases because NexentaStor pools 
       I/O operations as well as the underlying physical storage.
    -- Multi-level data integrity: data integrity for NexentaStor begins at
       the most basic level. Every transaction is verified, helping to 
       prevent the silent data corruption problems that haunt legacy 
       solutions. NexentaStor also supports a broad variety of RAID 
       approaches as well as the use of scheduled and policy based backups, 
       including file and block level backups.
    -- Built in search and ease of use: NexentaStor includes integrated
       indexing and search, saving time and simplifying the use of 
       increasingly granular incremental backups.
    -- Open systems and open approaches: perhaps the biggest difference
       between NexentaStor and legacy solutions is Nexenta does not force 
       you to buy special 'Nexenta hardware.' NexentaStor runs on industry 
       standard hardware including solutions from Sun, HP, Intel and others.



Evan Powell, CEO of Nexenta Systems said, "We're very proud of the launch
of NexentaStor Enterprise Edition 1.0 today. This launch is the result of the
effort of thousands of users and developers. With today's commercial launch
we've taken a significant step forward towards enterprise class storage for
everyone."

Since NexentaStor was first released as a freely available beta product
in November 2007 over 2,000 users have downloaded, installed, and registered
the storage management software. In March of 2008 Nexenta Systems released a
freely available Developer Edition v. 1.0, which is a fully featured version
of NexentaStor Enterprise Edition available at no charge.
