SSDL to Develop SCSI Solid-State Replacement Drives for Leading Semiconductor Fabricator’s Process Equipment
Reading, United Kingdom –Solid State Disks Ltd (SSDL), the advanced storage systems design, development and integration specialist, has won a contract to replace the hard disk drives in process equipment operated by a leading semiconductor manufacturer. The legacy drives, which have SCSI interfaces, reside in canisters within DEC BA353-AA and DEC BA356-KC towers, which originally were housed in three and six canisters, respectively.
As a minimum, the project will see SSDL replacing the HDDs with its highly reliable, CompactFlash (CF) based CF2SCSI™ SCSIFlash™ drives, which have already been evaluated by the customer on test beds and been subjected to live network testing. The interface to the host system’s SCSI connections will be accommodated using the SCSIFlash SSD drive, which supports CF drives up to 256GB and utilizes a 3.5 or 5.25-inch form factor.
“By combining SCSI and CompactFlash technologies, our SCSIFlash drive future-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 SSDL.
However, as the canisters and towers are also original equipment, and showing signs of wear, once the project commences it might be decided to replace the towers with solid-state solutions in either a rack or a new tower as at least another 10 years of service will be required of them.
“As the drives in legacy systems age and their electro-mechanical components fail, it is becoming increasingly difficult to replace or repair them as replacement drives and spare parts simply may not be available,” continues Hilken. “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.”
Hilken concludes by saying the replacement of just the drives represents the quick fix solution, but it doesn’t necessarily guarantee overall long-term reliability because of the age of the canisters and towers into which the drives will be placed. “We have a strong partnering philosophy and always align ourselves with our customers’ longer-term objectives, so biting the bullet and switching to solid-state towers may prove to be the best option.”

SSDL to Design ESDI Solid-State Drives for EDF Energy’s Heysham 2 Nuclear Power Station
Reading, United Kingdom –Solid State Disks Ltd (SSDL), the advanced storage systems design, development and integration specialist, has won a contract from EDF Energy to design and supply solid-state swap-in replacements for a number of obsolete CDC 182MB Wren hard disk drives. These will replace drives currently used in a Bull DPS6 computer at the company’s Heysham 2 nuclear power station on the northwest coast of England, and spare EDF energy from the considerable expense of replacing the host system.
The original Wren drives interface with the host system using the legacy American National Standards Institute’s (ANSI) Enhanced Small Disk Interface (ESDI) standard X3.170, which was popular in the late 1980s. SSDL will design a solid-state, flash-based drive that will be configured to emulate the behaviour of the original drive and communicate with the Bull DPS6 through ESDI. No changes will need to be made to the computer.
“ESDI had a relatively short life as an interface, as it had no sooner been standardised than it was superseded by ANSI’s Small Computer Systems Interface, SCSI,” explains James Hilken, Sales Director of SSDL. “In the past, we have supplied many solid-state replacements for SCSI-based drives, and still do, but in this instance we’re going to design an ESDI-based drive to meet EDF Energy’s immediate requirements.”
SSDL plans to base its new design on elements from its popular SCSI Flash (SF-2) and Floppy Flash (FF-1) products and will be designing new hardware (printed circuit board, PCB), firmware (in a field programmable gate array, FPGA) and software.
Hilken concludes: “There are essentially two halves to our emulator solutions, the solid-state Compact Flash part and a communication bridge. SCSIFlash is the bridge in our SCSI-based products, and the work ahead will effectively result in a new ESDIFlash bridge, which will then enable us to make available emulators for anyone else in need of replacing their obsolete ESDI-based drives.”
In addition to extending the life of its Bull DPS6, EDF Energy will also benefit from the high reliability of solid-state memory technology. Unlike a hard disk drive, there are no moving parts. Also, power consumption and heat generated are lower.
