Quick Introduction to Solid State Disks Ltd (SSDL) Reactive Groups ‘SSDL’ division delivers innovative system solutions to defence,

commercial and industrial customers worldwide. SSDL specialises in the design, development and integration of advanced storage

systems, focusing within the advance data storage in the military, traditional OEM and commercial storage product arenas.

The company historically designs and builds bespoke Solid State disk and tape emulators for legacy computer installations, many of which are installed in NATO and military environments.

Past design projects have included:- Nimrod Program Loading Unit (NPLU) BAE Harrier Flight Video Recorder Multiple Legacy Storage Replacement Solutions


Introduction As the members of IIOM are well aware there is often a requirement to

support specialised computer systems, well into their middle age, that must continue to operate in critical applications and difficult environments.

These ‘legacy systems’ are found in both defence and civil applications and may well have been inherited by their current support staff long after initial installation.

The list of such systems is extensive and includes radar display and air traffic control, aerospace ATE, telecommunications (public and private switch), weather systems, flight simulation, airborne reconnaissance, industrial process control, seismic data acquisition, and sonar/radar data logging.


These disparate systems often share a common set of four main problems caused, in part, by their specialised nature: -

1. Non-portable Software 2. Hardware Obsolescence 3. Operating Environment 4. The Non-“Standard” Interface The above identified problems are covered in greater detail within our White Paper ‘Data Storage Hardware Emulators for Legacy System Support’. Available upon request.


The ‘Hardware Emulator Solution’ In many cases it is possible to prolong legacy system life, and increase performance,

reliability, and environmental immunity, by identifying and replacing the high-risk hardware elements.

For hard disk, floppy and tape this can be done by emulating their function directly at the legacy interface level (plug compatibility) and using industrial grade Flash, e.g., Compact Flash (CF), for data storage.

• This may be removable when the original target drive / emulation requires it.

The cost per GB, and per device, is typically much lower than when the host system was first conceived, allowing increased storage capacity, flexibility and functionality.


The ‘Hardware Emulator Solution’ The ideal flash based, solid state emulator provides a general solution for legacy drive

replacement at product level. • The primary rule, almost the first law, is that the upgrade must not require software or hardware changes to

the target host system. • The second rule, and invariably the case, is that emulator reliability (MTBF) be improved far beyond the

original equipment specification, as should be the immunity to harsh environments.

There are no moving mechanical parts, and where the host system allows it, this often has the effect of increasing system throughput, as emulated access (seek) time can be greatly reduced.

Other advantages, in most cases, include a reduction in weight, power and audible noise.

The physical footprint can be reduced, but the standard approach is to provide a mechanically identical match with the product being emulated; fit, form and function.


The SCSIFlash™ Emulator Design, Problems and Solutions


The SCSIFlash™ Emulator Design, Problems and Solutions As the name suggests, the SCSIFlash emulator is a bridge, or interface adaptor, between

the original SCSI legacy interface and a Compact Flash (CF) card.

There are other adaptors on the market, but many adopt a single interpretation of the SCSI ANSI standard and, with fixed firmware, are often not compatible with the wide variety of host adaptors implemented in the real world.

The SCSIFlash emulator is a programmable emulating adaptor, aimed at replacing legacy data storage devices without requiring any changes to the host OS or device driver software.

The SCSIFlash design approaches the ideal, but the “one design fits” all is not achievable in reality.


The SCSIFlash™ Emulator Design, Problems and Solutions The need for programmability arises for a number of reasons, for example:

a. Limitations in the original standard and the “Vendor Unique” provisions.

1. As the SCSI standard evolved it needed to address the range of peripherals and product manufacturers emerging. This meant a degree of flexibility was introduced.

2. Supplementary documents were created for hard disk, removable MO disk, tape, and RAID.

3. Vendors were permitted to identify unique aspects of their product, including manufacturer, model type, capacity, etc. With many hosts it is essential to reflect similar data from the emulator to achieve correct operation.

b. Historically inadequate host design, aimed purely at integrating one product/host interface, without

full compliance with the SCSI standard or concern for second sourcing or future proofing, resulting in unique device dependency. There too many variations of this to describe here.


The SCSIFlash™ Emulator Design, Problems and Solutions

c. The standard SCSI block/sector size is 512 Bytes, but 256, 1024, 2048 and others are all possible and must be addressed in general purpose solution

c. 768 sector size in HDD’s are a fairly unique block size within the simulation systems market place.

d. A deliberate intent to make the interchange of products difficult in order to support the host

vendors’ marketing objectives.
