Technology: Vmirror Appliance
Vmirror mirroring appliance solutions are built around the Vicom engine, a high-speed, independent, SAN data mover. A patented design combines real-time OS, embedded hardware, and proprietary drivers to create an enterprise-hardened SAN appliance offering scalability, high-speed, and low-latency in a single SAN device. To achieve seamless interoperability, Vicom's block-level virtualization technology creates a SAN connection platform that transparently mirrors stored data regardless of make, model or version of storage system, attached hosts, or operating system platform and drivers. This all-hardware hardware design also enables Vicom appliances to protect and move SAN data at up to 8Gb/second (1400MB/second sustained) without affecting server or storage performance.

Vicom appliances use clustered engine pairs to form an "unbreakable," high-availability SAN device to deliver either data migration or mirroring services. Built-in block-level virtualization enables seamless connection of systems and storage of any make. No agents, additional software, or system changes are needed, greatly simplifying appliance installation and usage.
Interoperability among different SAN components requires the ability to handle subtle differences in communication protocols, timing, and device behavior from countless combinations of vendors and versions one of the reasons that most high-performance SAN solutions come from a single, rather than multiple vendors.
With mirroring, failover between different RAID systems can be complicated by incompatible behavior and timing often introduced by new drivers and software. Not only does this complicate installation and operation, but it also makes the maintenance task more difficult. Vicom has developed software, drivers, and hardware for the Vicom engine that have undergone years of testing and operation in the field. The result: Vicom delivers proven open-SAN interoperability that has withstood the test of years of different software and system releases from established vendors to startups. Bottom line: transparent, problem-free appliance operation with XSAN storage and host systems.
Clustering and modular redundancy create an appliance that delivers high availability with no single point of failure. In the event of power outage, the Vicom engine re-boots in ten seconds or less. Mirroring engines are clustered to provide high-performance, enterprise-level availability, and optional disaster-recovery configuration. Embedded, all-hardware mirroring design also offers significantly higher reliability than software mirroring and RAID-based appliances.
