ScaleArc iDB Deploys Transparently Into MS SQL Environments
      Without Modifying Applications or SQL Server Databases

SANTA CLARA, Calif., May 21, 2012 (GLOBE NEWSWIRE) -- ScaleArc, the
pioneer in a new category of database infrastructure that accelerates
application development by simplifying the way database environments
are deployed and managed, today announced general availability of iDB
v2.0 for Microsoft SQL Server that brings significant new capabilities
to SQL Server environments such as instant horizontal scaling, higher
availability, faster database performance, increased SQL protection and
real-time query analytics. iDB takes a fundamentally different approach
at the SQL protocol layer by providing customers with a wide spectrum
of capabilities for their database environment in a single solution,
without requiring any modifications to existing applications or SQL
Server databases.

Until now, moving to advanced architectures like multi-master, or
achieving instant scale and better performance within SQL server
environments, has been costly and extremely difficult to implement. iDB
v2.0 for MS SQL supports a wide range of functions including Read/Write
splitting, dynamic load balancing and horizontal scaling, query caching
for up to 24x faster query responses, wire-speed SQL filtering and
real-time instrumentation and analytics to enhance all deployment modes
of SQL server, including SQL Server Clustering, SQL mirroring,
Peer-to-Peer (P2P) Replication and log shipping.

"We simply plugged in the iDB appliance and it instantly accelerated
our queries and scaled our SQL server environment without requiring
hours of valuable engineering resources," said Dr. Aleksandr
Yampolskiy, Cinchcast CTO. "Cinchcast provides solutions that allow
companies to create, share, measure and monetize audio content. With
iDB, we're able to serve more ad impressions to enable greater revenues
for BlogTalkRadio, a Cinchcast-powered media property, plus the iDB
dashboard gives us new insights into ad traffic on the site, visibility
into the most frequent queries and more, so that we can better
understand the database load and how best to scale the system."

"iDB has proven itself in the MySQL community, solving problems that
are inherently difficult to solve within the database or applications,
like load balancing, caching, horizontal scaling, or query filtering
and others," said ScaleArc CEO Varun Singh. "With this release, we
bring all that experience to the substantial and growing customers of
Microsoft SQL Server."

iDB for MS SQL Feature Highlights


  --  Dynamic Query Load Balancing for High Availability: ScaleArc iDB
      implements a specialized dynamic load-balancing algorithm that allows
      the most efficient utilization of available database capacity, even when
      servers have varying capacity. iDB monitors query responses in real-time
      and can load balance queries to the server that will provide the fastest
      response to properly distribute the load. Up to 40% better performance
      has been observed with iDB's dynamic load balancing relative to
      TCP-based load balancing.
  --  Pattern-Based Query Caching for Increased Performance: ScaleArc iDB
      allows users to cache query responses with one-click. No changes are
      required at the database server or in the application code; the query is
      cached at the SQL protocol level, providing up to 24x acceleration
      without any modifications.
  --  Multi-master: iDB supports multi-master and master-slave scenarios to
      ensure high availability and scalability. Specific queries, irrespective
      of their origin, are routed to the right server with the advance query
      routing engine that also simplifies sharding.
  --  Real-time Analytics: Advanced graphical analysis tools provided by
      ScaleArc iDB bring comprehensive real-time awareness of all queries,
      helping to quickly pinpoint query patterns that are not performing
      optimally and allowing more precise management.
  --  Wire Speed SQL filtering: iDB is able to enforce query-level policies
      for security or compliance reasons to protect against attacks, theft and
      other threats. iDB can operate outside of the application where policies
      have not traditionally been easily enforced.
  --  SQL Query Surge Queue: Extreme loads can lead to unacceptable response
      times or even halting of operations until the load reduces, leading to
      "Database not Available" errors. ScaleArc iDB allows a more graceful
      response to peak loads. When faced with an extreme load, ScaleArc iDB
      can initiate a SQL Query Surge Queue and momentarily queue queries in a
      FIFO queue and process them once server resources become available.




iDB for MS SQL provides support for SQL Server 2005, 2008, and 2008R2
and will support 2012 in the near future.
