NEC NEAX Σ (Sigma)

Solid State Disks Ltd

Dependable Data Storage Solutions

We offer high reliability solid-state replacement drives for a wide variety of telecoms equipment.

Our CF2SCSI™ SCSIFlash™ drives can be used to replace drives with either internal storage media, such as magnetic HDDs and SSDs, or which use removable media, such as magnetic tapes, optical disks (CD / DVD), floppies and solid-state memory cards.

The Sigma makes use of DAT tape drives for backup purposes. The DAT drives are a more advanced (and smaller) type of tape drive from those used in the NEAX 61E. Therefore, NEC NEAX Sigma Magnetic Tape Emulation requires a slightly higher speed SCSI-like interface.

If you have an NEC NEAX Sigma exchange system and its legacy data storage device is starting to fail, or you fear it might soon, we can help.

Where to next?

What is CF2SCSI™ 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 (SASI, SCSI-1, SCSI-2) with industry-standard, solid state Compact Flash (CF) card technology our CF to SCSI (CF2SCSI™) SCSIFlash™ is a solid-state drop-in replacement for any style of SCSI-based drive. Moreover, we can accommodate a variety of connector/interface types including, but not limited to, Pertec, QIC DAT, DLT 3490, Jazz, ZIP and Bernoulli.

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