SSDs in use on 3000s: Virtualized by now

Earlier this week, a 3000 devotee and technician asked if anyone was using solid state disc (SSD) on HP 3000s in place of the aging SCSI drives in most servers. "It sounds like a great concept," said Jon Jonston, who's working on a preservation project for the HP Computer Museum.

We are just looking to restore images onto a disc for demo purposes. So, even powered down life is not important, but cost is. We have found that IDE->CF works great as a hard disc replacement in old DOS PCs. SCSI2SD is a great low-cost solution (for Apple), but doesn't work with HP. We are looking for a low-cost, single disc SSD for HP 3000 computers.

SSD DriveAfter one newsgroup user compared putting SSDs in 3000s to a McLaren racing engine in an SUV, a more plausible solution emerged: using SSDs to support a virtualized 3000 running on an Intel-based PC. "You could house your 3000 in a Stromasys emulator running on a Linux box with VMware," said Gilles Schipper, "employing as many SATA SSD disks as you want on your host."

But there was a time in another May when SSDs running native in HP's 3000 hardware was a possibility worth investigating.

It was almost six years ago, and the Charon emulator was not yet announced. Extending the future of the HP hardware was more of a necessity for a homesteading user. Stan Sieler of Allegro said he'd be looking into what would be needed to bring solid state storage to MPE.

"I'm thinking about SSD and SATA/SCSI adapters to speed up the 'obsolete' -- but still world's-best -- business computer, the HP 3000," Sieler said in May of 2009. "I'm hoping to do some tests in the near future."

Sieler said that those SATA/SCSI adapters would be a crucial part of putting SSD on its MPE feet. "Few SSD drives have SCSI interfaces... hence the SATA/SCSI adapter component," he said. "An SSD with a SCSI interface would look completely like an SCSI disk drive."

This kind of design, to mimic the SCSI interface, would've helped to avoid using the SCSI Pass-Through code HP engineered during 2007. The community still hasn't heard reports of how the pass-through works, and HP said that employing it is "not for the faint of heart."

A computer museum would need to ensure that old hardware could be represented in its original form. An IT shop preserving MPE applications, instead of the platform -- not so much. A virtualized 3000 will do. Craig Lalley checked in to report that his Stromasys Charon installation runs from an SSD.
