1.5 Configurable Backup

The RamSan-120 allows the administrator to set backup modes for each

LUN individually or system wide.

Datasync mode

In DataSync mode, the system reads and writes data to memory only.

The disk remains offline during normal operation. If power loss occurs and

the shutdown timer reaches zero, or the user requests a shutdown, the

system takes the Fibre Channel interfaces offline and synchronizes all data

to the internal hard drive.

None (Volatile) mode

This operational mode disables the backup functionality for the LUN

making it completely volatile. In the case of system shutdown or failure,

all data stored in the selected LUN will be lost intentionally.

The RamSan-120 series solid state disk is the ultimate in performance

storage. With two Fibre Channel ports in a 1U package, the RamSan-120

delivers powerful bandwidth and I/O. The RamSan-120 series is capable of

70,000 IOPS (I/O operations per second) and 400 MB/sec of read or write

performance.
