Solid State Disks Ltd develop SCSI solid state replacement for DEC BA353 and BA356 tower

Reading, UK –Solid State Disks Ltd (SSDL) win SCSI CF Solid State upgrade contract with major semiconductor fabrication to upgrade the SCSI drives on their BA353 and BA356.

Solid State Disks are able to replace the RZ29B-VA drives individually or alternatively replace the DEC BA353-AA or Digital BA356-KC Hard drive expansion units entirely with a new solid state tower. Other DEC drives supported.

The CF Solid State Disk Drive has passed the customers test beds and live network testing and is currently deployed in a major UK fab network

DEC BA353-AA or Digital RA356-KC Hard drive expansion units can be replaced with the CF Solid State Disk Drive.

Existing mechanical expansion units are configured as DKA:0 to DKA:600. With the new SCSI SSD Solid State Tower the drives are identified the same for the Solid State SSD installed. ie. DKA:0, DKA:100 and DKA:200.

Solid State Disks Ltd (SSDL), the advanced storage systems design, development and integration specialist, manufacture the CF2SCSI SCSIFlash drive™which solves the growing and increasingly expensive problem of repairing or replacing ageing and failing SCSI-based hard disk (3.5 inch and 5.25 inch HDD), magneto optical (MO), quarter-inch tape (Pertec, QIC DAT, DLT 3490), Jazz, ZIP, Bernoulli and floppy (FDD) drives on computer-based legacy equipment. The SCSIFlash™ driveprovides a low-cost, solid state drive replacement that enables Compact Flash cards to be seen as SCSI drives by the host system.

The SCSI solid state flash disk combines proven SCSI drive architectures (SASI, SCSI-1, SCSI-2) with industry-standard, solid state Compact Flash (CF) card technology to provide a highly reliable, solid state drop-in replacement for any style of SCSI-based drive including hard disk, magneto optical, tape and floppy drives. Importantly, SCSI Bridge is completely programmable, enabling the SCSI driver implementation nuances of all equipment manufacturers to be fully emulated.

The Solid State CF Disk Drive solution applies to a broad range of computer-based legacy equipment in a spectrum of industries and markets from telecommunications and broadcasting through to industrial process control, factory automation and instrumentation,semiconductor manufacturing, point-of-sale and mil/aero applications.

The SCSI Bridge drive currently supports CompactFlash drives up to 256GB and utilizes a 3.5 inch form factor (or larger 5.25 inch form factor). It is available in two package types either with no externally removable card as a hard disk replacement or with an externally removable CompactFlash card slot as magneto optical, Jazz, ZIP, tape or floppy drive replacement. Microcode is field-upgradeable via the integral RS-232 serial interface which also enables real-time diagnostics to be undertaken. Board power is only 5V and there is an optional add-on display and push-button user interface for use with the tape package.

“By combining SCSI and CompactFlash technologies, the SCSI Bridge drivefuture-proofs computer-based legacy equipment that depends on worn out and obsolete SCSI drives for which replacements and spare parts are scarce,” said James Hilken, Sales Director of Solid State Disks. “As the SCSI drives in legacy systems age and their electro-mechanical components fail, it is becoming increasing difficult to replace or repair them as replacement drives and spare parts simply may not be available. Sourcing second-hand units to cannibalize doesn’t really provide a lasting or safe solution either. In contrast, using the SCSI Solid State Drive and Industrial CompactFlash technology to replace them provides a low-cost, fast and efficient solution that increases reliability and reduces unplanned downtime due to its solid state, non-moving part design.”
