MPE/iX · The clock ticks on

Time goes on.
The clock ticks on.

For four decades, Allegro Consultants has kept mission-critical HP 3000 and HP-UX systems running non-stop - and we're built to keep them running for decades to come.

Excellence in OS support · Non-stop since 1974 · No end-of-life here

Flagship hardware · MPE/iX · HP-UX

When the tape drive dies, the HP 3000 shouldn't.

Devices on Demand drops into your SCSI port and emulates every HP-supported tape drive, C1537A, DLT, and LTO, with a virtual tape library that holds hundreds of tapes on a single SD card. Every dead or dying drive on your shelf, replaced by one small box.

  • Every HP tape drive, in one box. Emulates the full lineup HP supported, C1537A (DDS), DLT7000, DLT8000, and LTO, so MPE/iX STORE/RESTORE and SLTs, and HP-UX fbackup/frecover, just work.
  • A virtual tape library, built in. Hundreds of virtual tapes on a single SD card, the whole tape room, on a chip.
  • Backups become files. Every virtual tape is just a file, copy it, archive it, take it home.
  • Bus-powered, no cord. The SCSI connection is all it needs. Nothing else to plug in.
  • Protocol-accurate. Verified against HP's own driver source, so your host sees a genuine HP drive.
Devices on Demand: a bus-powered box that plugs into the SCSI port and emulates an HP 3000 virtual disk, tape, and library subsystem from an SD card.

A note on ownership

Allegro's next chapter.

For forty years, Allegro Consultants has kept mission-critical HP 3000/MPE/iX and HP-UX systems running long after their makers moved on.

As Donna Hofmeister begins a well-earned retirement, that mission continues without interruption. Allegro's support operations, products, and deep systems expertise are now managed by Craig Lalley and EchoServ, LLC.

Same systems knowledge. Same responsive support. New stewardship.

- Craig Lalley, EchoServ, LLC
