Solid Data Receives Patent for Messaging Architecture Enabled by Solid State Disks (SSDs)

Hierarchical Storage Method Provides Improved Performance for E-Mail With Lower Storage Cost

SANTA CLARA, CA -- (MARKET WIRE) -- December 4, 2006 -- Solid Data Systems, Inc., the leading global provider of solid-state storage systems, announced today that its messaging architecture application has been allowed by the United States Patent and Trademark Office and a patent is expected to issue soon. The patent covers a messaging architecture which maintains recent, high activity e-mails or messages in a database on Solid State Storage, and migrates older, less active messages to network-attached storage.

"This patented messaging architecture utilizing Solid State Disks (SSDs) provides three major benefits," said Wade Tuma, Founder and CEO of Solid Data. "First, it offers very high performance for recent e-mails, especially on commercial e-mail systems with a large user base. Second, it reduces the cost of storage for older, less active messages. And a final benefit as a result of implementing this method is that it allows for extremely fast recovery of a smaller database, virtually eliminating e-mail system downtime."

"Envision a recovery scenario in which a storage device holding a large messaging database fails after a whole day's worth of transactions have been completed -- but prior to a full database back-up," explains Mark Hayashida, Director of Systems Architecture and Sales Engineering of Solid Data. "The server may be required to re-process the entire day's transactions, and users may be deprived of e-mail service for an extended period of time."

In conventional solutions, the server repopulates Inboxes in the order the messages were received, which requires rotating disks to seek randomly. This process can be extremely slow when a large number of messages needs to be recovered; e-mail service may be completely down while this operation is in progress. With Solid Data's messaging storage solution, not only does the SSD seek in microseconds rather than the milliseconds of rotating disks, allowing for more frequent backups without impacting user performance, but also the database is smaller because it contains only recent messages.

About Solid Data SSD Storage Systems

Solid Data's SSD storage systems store and retrieve data with a latency of less than 10 microseconds, making these appliances the highest performing low latency non-volatile, external storage systems in the industry -- 500 times faster than mechanical disk storage. They provide a high-performance alternative to spreading files over a large numbers of rotating disks to achieve desired application performance. Although more expensive than rotating disks in cost per byte, in appropriate applications, Solid Data's SSDs dramatically lower overall cost per transaction by lowering server, storage, licensing, and maintenance costs, while improving reliability and uptime.

Databases driven by highly transaction-oriented applications benefit greatly by placing the entire database structure on SSD. For databases that contain portions of static data, subsets of the database that have critical impact on performance (such as redo, roll-back or transaction logs, temporary sort areas, indices, and heavily accessed tables) are stored on SSD, while data less critical to application performance are stored conventionally. In either configuration, the result is significantly improved performance and reliability, at a lower cost per transaction.

All SD2000 and SD3000 systems are designed with high-bandwidth data paths and dual Fibre Channel connections with path fail over. Other high-availability features include patented error detection and correction (EDAC), and Solid Data's Remote Monitoring and Reporting (RMR™) feature. RMR supports SNMP for traps and monitoring with packages such as CA Unicenter, HP OpenView and IBM Tivoli. RMR also supports a password-protected Web browser interface and e-mail alert notification for anytime, anywhere remote monitoring and diagnostics.

The SD3000 and SD3000X2 are the only SSDs to feature the PermaRack™ chassis. Exclusive to Solid Data, PermaRack allows easy field servicing of every internal component via plug in modules without de-racking. This means precious up-time is never wasted during any maintenance window and service can be completed in mere minutes. Normal maintenance of Uninterruptible Power Supplies, fans, batteries or internal backup drives can be done while on-line and operating.
