San Francisco, CA, May 11, 2005 – Nimbus Data Systems, Inc. (www.nimbusdata.com) today announced the general availability of Hot Mirror, an optional software feature for its recently released IPS-1200/1600 series of iSCSI storage systems. With Hot Mirror, small and midsize organizations can deploy a fully fault-tolerant IP SAN, with mirroring and failover across two independent storage arrays, for under $25,000, providing unmatched availability and data protection in its class.

Affordable High Availability Storage Infrastructure
Downtime is intolerable for rapidly-growing organizations that depend on non-stop email and server access for core business functions. To date, high-availability systems have been very expensive, forcing businesses to compromise data availability to meet their budgets. With this in mind, Nimbus developed Hot Mirror as an extension to its popular IPS series of cost-effective iSCSI storage systems.

Using synchronous mirroring, data on one Nimbus appliance is seamlessly copied to a second standby appliance. In the event of a failure, the standby appliance automatically takes over without any disruption to applications or servers. As a block-level copy, Hot Mirror guarantees data consistency between the two Nimbus appliances, without requiring any host-based software. Unlike dual controller storage systems, Hot Mirror further protects the most valuable asset of all – the data itself. While all Nimbus systems have redundant components and RAID, Hot Mirror provides an additional level of protection for applications that demand zero downtime, such as email, database and ERP servers.

Availability and Pricing
Customers can add Hot Mirror to their Nimbus IP SAN by upgrading their license key for $2,500 per IPS system. A complete 99.999% availability IP SAN, with 1.6 TB of capacity, Hot Mirror, and Nimbus SAN Manager starts under $25,000, including three years of comprehensive Silver Support.
