Stratus Technologies Releases Avance, Integrates With Citrix XenServer for Software-Based High-Availability Solution

Stratus Technologies

Stratus Technologies has announced (PDF) its Stratus Avance software, the company’s first software-based high availability (HA) product. Using embedded virtualization and running on ordinary x86 servers, Avance claims to provide levels of availability superior to, and without the complexity of, high-availability cluster solutions for Linux and Windows applications.

Stratus’ new software-based solution targets the SMB market as well as “edge” applications in large distributed networks where IT-staff support is minimal or non-existent. Prospective customers include medical practices, retail chains, small companies, branch banks, remote office or departmental computing, or distributed warehouses, distribution hubs or manufacturing facilities, for example.

Unlike other high-availability solutions, Avance HA positions itself as instant and automatic. Processing takes place on one server and data is simultaneously written to the mate, which can seamlessly assume
processing duties at any time should the primary server go out of service. If that happens, the affected server is removed from the network, alerts go out to user-defined recipients, a repair is made, and the server is brought back online to resynchronize with the active node with no downtime or data loss.

Avance is integrated with Citrix XenServer, and the U.S. list price for Avance software is $2,500 per server (including the license for Citrix XenServer). Avance software is available from Stratus channel partners and distributors, and in volume purchases directly from Stratus.
