Rorke Data, Inc.s family of Fibre Channel RAID maximizes digital storage performance for a wide range of applications Galaxy 5 builds on Rorke's expertise in high-bandwidth technology applications such as digital video streaming, computer-to-plate, and diagnostic imaging. Galaxy 5 provides RAID 0/1(0+1)/3/5/JBOD capabilities to any system equipped with a SCSI interface, as well as redundant controller capability with synchronized write-back cache.

The Galaxy 5 can simultaneously distribute multiple requests from hosts to connected SCSI drives in order to perform high-speed parallel data transfer. To achieve the highest data throughput, full Ultra2 Wide SCSI support, including concurrent I/O and tagged command queuing are implemented in the Galaxy 5. The Galaxy 5 uses high performance processors for intelligent I/O task optimization. The caching function is designed with intelligent read-ahead and write-back. Because of the highly scalable design, the Galaxy 5 provides an optimal mass storage solution for a wide range of SCSI-based computers, single-user workstations, high-end NT servers, and UNIX systems.

The Galaxy 5 can provide RAID 0, 1(0+1), 3, 5 and JBOD options. These RAID functions can guarantee the user the highest in data availability and protection using capabilities like automatic drive failure detection, hot stand-by, global spare, automatic rebuilding, hot swap, on-line background rebuilding, on-line RAID expansion, etc.

The base module can be upgraded to have more SCSI/Fibre Channels with an optional daughter-board without any difficulty. The 160-pin docking connectors integrate all SCSI channel's signals for easy one-step installation. Each of the Galaxy 5's SCSI/Fibre Channels can be defined as either a drive channel or a host channel. This allows the connection of multi-host systems through independent channels. Channel 0 of the Galaxy 5 can be further assigned as synchronized cache port for active-active redundancy. The Galaxy 5 can even handle bad sectors on drives during disk read or write commands. It can recover the data from other drives of the same logical drive and do bad sector reassignments. And it does all this in a manner transparent to the host.

With the Galaxy 5,customers are able to choose from a minimum of 4 channels up to a maximum of 8 channels with upgrade boards. Users can also elect up to 2 FC hosts with the added option of redundancy.

The Galaxy 5 can be configured in several ways:

  • Push-button interface for stand-alone configuration and monitoring.
  • RS-232 Terminal Emulation providing easy-to-use text-based menu-driven configurations and monitoring.
  • Text RAID manager offers the same look and features as the terminal emulation, but allows for remote administration via SNMP.
  • GUI RAID manager providing a user-friendly graphical environment with which to configure and monitor the disk array system through the RS-232C interface or in-band SCSI.
  • 24-hour hot swap is available at most locations
  • Standard 9x5 and 24x7 maintenance and support are generally available in most metro areas
  • Please check with your Rorke representative for remote area response times.
