xkoto Unveils GRIDSCALE 5.1
xkoto (, the database virtualization company, today announced it is previewing the new release of GRIDSCALE 5.1, the latest edition of its leading active/active solution for mission-critical databases, July 13-16, at the Microsoft Worldwide Partner Conference (WPC) in New Orleans, booth 906. General availability of the product is expected in Q3, 2009.

Currently in beta testing, GRIDSCALE 5.1 adds several features that improve the performance and compatibility of the industry’s first shared-nothing solution for commercial databases. Two key GRIDSCALE features in this release are native Microsoft SQL Server support and a new Cluster Lock Manager.

GRIDSCALE 5.1 features a new “driverless” configuration mode for SQL Server environments, eliminating the need to reconfigure database drivers. Implementing Microsoft SQL Server’s native communication protocol, GRIDSCALE delivers several benefits, including compatibility with most native SQL clients such as ADO, .NET, OLE DB, and others. Plus, IT professionals can now use GRIDSCALE to simultaneously manage multiple SQL Servers using existing, popular tools such as SQL Server Enterprise Manager.

GRIDSCALE’s patent-pending Cluster Lock Manager is an industry first, enabling reliable scaling of transaction-intensive workloads across independent database servers. Traditionally, relational databases have relied on distributed lock management solutions to coordinate transaction locking across disparate database servers. These approaches have significant drawbacks, such as risk of a single point of failure, poor performance due to synchronous behavior, and significant management overhead. GRIDSCALE’s new Cluster Lock Manager operates completely transparent to an application to isolate and coordinate row-level transactions across database servers. As a result, applications can scale reliably across the pool of database servers managed by GRIDSCALE.

“GRIDSCALE is far and away the most advanced active/active database technology on the market, providing availability and scale-out performance for the most critical business applications,” said David Patrick, President and CEO, xkoto. “GRIDSCALE’s new native SQL Server support and enhanced locking mechanism will enable an even broader set of IT applications to benefit from scalability on demand and continuous availability.”

GRIDSCALE is an active-active solution that virtualizes the database infrastructure. It enables businesses to distribute application loads horizontally across multiple database copies, resulting in better reliability and performance than that of more costly and complex legacy clustering solutions. With GRIDSCALE, businesses can eliminate planned and unplanned outages, rapidly scale application load across database servers, and implement cost-effective disaster recovery solutions.
