G503 - Dual SATA HDD/SSD Shuttle & RAID Controller

2.5" HDD or SSD

The G503 is a CompactPCI Serial drive carrier board for use in a system environment with an x86 processor. It is designed to carry two 2.5" SATA mass storage drives.

SATA RAID Controller

The storage drives are controlled by an on-board SATA RAID Controller supporting RAID modes 0, 1 and JBOD as well as hot plug capability. The RAID level can be set using a hex switch on the board.

The G503 can be used to supplement the RAID functionality provided by the CPU board in order to implement data storage systems with high reliability and capacity.

Front Panel Status LEDs

The unit's front panel features six LEDs signalizing board status (Power, Locate, Activity, Hot-Plug/Error and Eject).

For Mission Critical Tasks and Harsh Environments

The board supports a 2 ms HDD power hold-up time for protecting the stored data in case of a power failure, which makes it applicable also for mission-critical tasks.

In addition to industrial applications, its compliance with the EN 50155 standard makes the board also suitable for railways applications.
