    High Availability Servers for Your Most Important Applications

    FlashServer HA Redundant Failover Servers provide an innovative hardware solution to address planned and unplanned downtime for your most important applications. FlashServer HA delivers continuous uptime through its fully redundant modular hardware featuring Intel Xeon E5 processors with up to ten cores each. These servers provide continuous availability through hardware redundancy in all components: CPU, memory, motherboards, I/O, hard disk drives, power supplies and cooling fans. Two servers in one unit run applications simultaneously so if one fails, the other takes over immediately with no lost data and no delays common to cluster solutions. Best of all, only one set of software licenses is needed, delivering big savings compared to cluster software solutions.

    Five 9s Reliability

    Failover with the FlashServer HA is automatic and transparent to the OS, virtualization software, applications, and users. The environment can survive a drive, motherboard, CPU, RAM, bus, power supply and fan failure. The result is a realizable 99.999% uptime without clustering. For the utmost in reliability and to protect against both hardware and software failures, FlashServer HA servers work exceeding well in cluster environments—delivering a double layer of protection: fault tolerant servers and cluster failover. Plus, clustering provides load balancing and other benefits.

    Overwhelming Cost Savings

    To run in redundant mode, the HA Server requires only one copy of the operating system and application software; no professional services are needed to setup or configure the server. It’s simple to setup, simple to use, and simple to maintain.


    FlashServer HA installs just like any other standard Intel server, saving tremendously on professional services and reducing—or eliminating—the need for specialized staff to support complex cluster environments. FlashServer HA implements server redundancy at the hardware level, reducing failures to automatic notifications and indicator light status. This approach significantly reduces the complexity associated with other forms of high availability such as server clustering. It also simplifies system management and recovery operations, since administration and configurations are performed from a single-system view.

    Uninterrupted Operation

    Eliminating minutes of downtime for a cluster failover and avoiding a data loss provide substantial recapture of otherwise lost revenue often measured in thousands of dollars per minute.
