HP's storage for the 3000 was always a step later to arrive than on the Unix side of the business line. Sometimes a storage protocol like an SCSI bus was rated at half the speed of the HP-UX version, even though the technology was identical on the storage device. MPE/iX needed more stringent testing, the customers figured, to assure the world that the legendary 3000 reliability was intact.
Sometimes the delays in tech covered years, until at one point HP stopped all of its MPE/iX testing. That didn't mean the community quit innovating and integrating storage. Now the XP P9500 storage arrays have been proven to support N-Class servers, according to the reseller ThomasTech.
"It was a success," said global services director Chad Lester. "Our engineers have the HP3000 N-Class booting from the P9500."
The P9500 has a standards-based architecture, using X64 processor-based controllers, and a user-centric design plus application-level quality of service controls. HP claims the P9500 doubles power efficiency and holds the same amount of data as the XP24000 in half the floor space.
It's a new storage technology to the 3000 world, even if the basic design was first rolled out almost eight years ago. The tests at ThomasTech show that MPE/iX can be installed on the first LUN, according to engineer Larry Kaufman. The next steps are to be able to boot a system from that P9500.
Storage solutions have held the greatest promise for extending the life of HP-branded MPE/iX hardware. The XP24000 arrays, for example, have been a source of massive storage capacity that can be shared across a wide range of server environments. The XP support has marched onward for years. The P9500 can scale from five disk drives in a single cabinet to 2,048 drives in six industry standard, 19-inch racks. The P9500 tops out at less than half of the XP24000's theoretical limit of 2.26 petabytes, though. SSD and moving media are both supported.
And there's that word, petabytes, being associated with a server HP stopped building 15 years ago.
