SSDs: Not a long-shot to work with MPE/iX

Hewlett-Packard Enterprise is not entirely sure if it's leaving the support forum it once devoted to the HP e3000. (After so many years, "e3000" is still the go-to keyword while looking at the HPE resources that remain online.) To test if the forum was still alive, or entirely in archive stasis, I posed a question. Could an IDE SSD drive get a hookup to a 3000 using an SCSI converter?

Is there enough bus connectivity in the e3000 to install an SSD on the server? There are SSD drives that can link up via IDE and I've found a SCSI to IDE converter.

One reply bounced back on the forum. "Torsten" said, "If this is really an HP3000 server, this sounds like the most crazy tuning idea."

Not so crazy, we've seen. In 2015, after one 3000-L 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 of GSA, "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 also a necessity, because it was the only way.

It was almost six years ago, and the Charon emulator was still in development. Extending the future of the HP hardware still 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, 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 HP-hardware based 3000 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. The Stromasys Charon installations can be run from an SSD.
