1.4 Reliability

The RamSan-500 is designed to offer superior reliability to other solid- state disks and RAID devices. Its standard features include Chipkill™- protected RAM, hot-swap modular Flash memory, hot-swap power supplies, failover ports, and SNMP compatibility. The nine-unit RAID design ensures data integrity even in the event of the complete failure of a single Flash module. In order to reduce the probability of a Flash module failure, the unit incorporates multiple error-correcting methods.

1.5 System Management

Basic management operations, including manual shutdown and alerts, are available from the front panel screen. Full monitoring and configuration capabilities are available over any browser via a password protected Java applet. The RamSan-500 also offers Telnet management capabilities and is fully SNMP compatible.
