The PowerSAN's reliable controller provides dual controller host independent active-active failover and failback capabilities. Automatic failover initiation in the PowerSAN's controller utilizes new run time diagnostics and error handling software. This results in no downtime for maintenance operations, a key requirement for mission critical applications. The PowerSAN's Fibre Channel controller provide unprecedented performance and high data reliability to meet the demands of today's enterprise storage environments. Easy Design-in Circuitry for the PowerSAN was specifically chosen for both high performance and low power requirements.
Lower power translates into less expensive cooling requirements and higher reliability.
It also contributes to longer data cache protection time when using the PowerSAN's cache battery pack. Up to 72 hours of cache uptime can be achieved in the event of a power loss, maintaining valuable data for over three days. The utility allows users to configure the controllers and arrays, read event logs, and monitor numerous hardware and software conditions over the RS-232 interface. Firmware is embedded in the PowerSAN's controller to monitor voltage levels of all incoming power, cache battery pack voltage and temperature, CPU temperature, and controller ambient temperature. Warnings are provided over the management interfaces.
