Equipment That Uses The iRMX Operating System

Solid State Disks Ltd

Dependable Data Storage Solutions

We offer high reliability solid-state replacement drives in the process and manufacturing sectors in a variety of industries, including Food & Beverage, Chemicals, Oil & Gas, Power Generation, Pulp & Paper and Automotive.

If you have manufacturing equipment that uses the iRMX operating system (developed by Intel and popular in 1970s and ‘80s) and its hard disk drive (most commonly the Quantum Pro Drive ELS 54) is starting to fail, or you fear it might soon, we can help.

Over the years there have been several variations of iRMX – including iRMX II (16-bit) and iRMX III (32-bit) – used with host processor such as SBC 386/12S, SBC 486/12S, SBC 486/133SE, SBC 386/258, and/or with SCSI controllers like SBC 221S.

Our CF2SCSI™ SCSIFlash™ drive has been validated against ALL known (to us) versions of iRMX and can be used as a swap-in replacement for the Quantum Pro Drive ELS 54.

Importantly, no changes need to be made to your host system; it will treat our drive as if it were the original part. In addition, you benefit from the high reliability, improved performance (such as fast and simplified memory erase for security) and reduced noise and power consumption that all come through switching to latest technology solid-state memory.

Also, all our CF2SCSI™ SCSIFlash™ drives can be fitted with an Ethernet port, enabling them to be networked and accessed through our Windows (7 or higher) based Flash2GUI memory management software.

Where to next?

What is SCSIFlash™?

Our drive solves the growing and increasingly expensive problem of repairing or replacing ageing and failing SCSI-based 2.5-inch, 3.5-inch and 5.25-inch hard disk drives, magneto optical drives, quarter-inch tape drives and floppy disk drives on computer-based legacy equipment used in telecoms and other industries.

Combining proven SCSI drive architectures with industry-standard, solid-state Flash-based memory technology, our drives are drop-in replacement for any style of SCSI-based drive.

We have two families of products:

  • SCSIFlash™. The storage media used is Compact Flash (CF), up to 128GB capacity, and the SCSI interface (SASI, SCSI-1 and SCSI-2 architectures) is standard (narrow) 8-bit with data transfer rates of up to 10MB/s.
  • SCSIFlash-Fast™. The storage media used is either CFast or M.2 SSD, up to 1TB capacity, and the data transfer rate is up to 80MB/s. SASI, SCSI-1, SCSI-2 and Ultra3 are supported, and the interface is automatically detected as being standard/narrow (8-bit SCSI, wide (16-bit) SCSI, single-ended (SE) or low voltage different (LVD) signalling.

Our drives are completely programmable, enabling the SCSI driver implementation nuances of the original equipment to be fully emulated. This means you won’t have to make any changes to your system. Our drives are truly swap-in replacements.
