xkoto GRIDSCALE
True Load-Balanced Parallel-Processing MS SQL and DB2 Databases For Both High-Performance Scalability and Continuous Availability With GRIDSCALE you can:
By sharing the load across multiple servers, the loss of any one server does not have an impact on the availability of the service. In addition, since servers can be taken off-line without impact, you can perform rolling upgrades on the database servers for true continuous availability.
Performance tests show that with each new database server added to the cluster, application performance scales in a near-linear fashion, particularly for read-intensive applications. With GRIDSCALE you can scale your application horizontally across low-cost servers and virtual machines. Plus you can provision and de-provision database servers to accommodate the changing needs of your applications.
GRIDSCALE is the only database virtualization solution of its kind to support both synchronous and asynchronous data replication between commercial databases in a pool. GRIDSCALE replicates all write statements (inserts, updates, deletes and DDL) in real time to every database server in the grid simultaneously. In its default asynchronous mode, GRIDSCALE does not have to wait for every response before signaling statement completion. The response from the first database server to finish processing the statement is sent back to the application ensuring the fastest response time. The other database servers continue to process the statement normally thereby ensuring that data is replicated on all servers. GRIDSCALE can also operate in synchronous mode, whereby it waits for responses from all database servers before returning a response to the application.
GRIDSCALE supports databases running on multiple platforms, including mixed operating systems or mixed databases. For example, with GRIDSCALE, you can run a pool of DB2 on Linux and SQL Server on Windows. It provides IT architects with unprecedented flexibility to design applications for availability and performance, to migrate platforms or database versions, and to replicate data between disparate systems.
GRIDSCALE uses standard interfaces to control communication between applications and underlying databases. GRIDSCALE comes with JDBC and ODBC compliant drivers, and also supports .NET to minimize application changes or changes to the underlying database definition. Also, GRIDSCALE offers a non-intrusive, cost-effective Assessment Service to provide compatibility assurance for your applications.
GRIDSCALE eliminates the need for expensive and intensive data replication strategies between production and disaster recovery (DR) sites. With GRIDSCALE you can solve both HA and DR issues with a single solution. Using a highly efficient communication protocol, GRIDSCALE allows database servers to span multiple, geographically dispersed data centers. As a result, you can load balance across multiple data centers, tap into idle capacity at DR sites and ensure that your DR database is always up-to-date.
GRIDSCALE's Web-based console and command-line interface provide straightforward management and administration of GRIDSCALE and database servers. Diagnostic and fault event notification for GRIDSCALE and the underlying managed environment can be forwarded to an enterprise management system for processing.
