HP's A-Class 3000s aren't that powerful, and they're not as readily linked to extra storage. That's what the N-Class systems are designed to do. But at one service provider's shop, the A500 is plenty powerful enough to keep a client's company running on schedule, and within budget. The staying power comes from customization, that sticky factor which is helping some 3000s remain in service.
The A500 replaced a Series 987 about a year ago. That report is one point of proof that 9x7 systems are still being replaced. It's been almost two decades since the 9x7s were first sold, and more than 15 years since the last one was built. The service company, which wants to remain unnamed, had good experience with system durability from the 3000 line.
We host a group of companies that have been using our system for over 20 years. So, we’re planning on being around for a while. One of these customers may migrate to a Windows-based system over the next few years, but I anticipate that this will be a slow process, since we have customized their system for them over the years.
The client company's top brass wants to migrate, in order to get all of its IT onto a single computing environment. That'd be Windows. But without that corporate mandate to make the IT identical in every datacenter, the company would be happy staying with the 3000, rather than looking at eventual migration "in several years' time." It will not be the speed of the server that shuts down that company's use of an A500. It will be the distinction that MPE/iX represents.
HP sold that 2-way A500 at a list price of just under $42,000 at the server's 2002 rollout. In contrast, those bottom-end A400s had a list price of about $16,000 each. Both price points didn't include drives, or tape devices. Our columnist at the time, John Burke, reported on performance upgrades in the newer A-Class systems by saying
There is considerable controversy in the field about the A-Class servers in particular, with many people claiming these low-end boxes have been so severely crippled (when compared to their non-crippled HP-UX brothers) as to make them useless for any but the smallest shops. Even if you accept HP’s performance rating (and many people question its accuracy), the A400-100-110 is barely faster then the 10-year-old 928 that had become the de-facto low-end system.
I see these new A-Class systems as a tacit agreement by HP that it goofed with the initial systems.
The power of the iron is just a portion of the performance calculation, of course. The software's integration with the application, and access to the database and movement of files into and out of memory -- that's all been contributing to the 3000's reputation. "I’ve been working on the HP since 1984 and it’s such a workhorse!" said the service provider's senior analyst. "I've seen other companies that have gone from the 3000 to Windows-based systems, and I hear about performance issues."
Not all migrations to Windows-based ERP, for example, give up performance ground when leaving the 3000 field. We've heard good reports on Microsoft Dynamics GP, a mature set of applications that's been in the market for more than a decade. Another is IFS, which pioneered component-based ERP software with IFS Applications, now in its seventh generation.
One area where the newer products -- which are still making advances in capability, with new releases -- have to give ground to 3000 ERP is in customization. Whatever the ERP foundation might be at that service provider's client, the applications have grown to become a better fit to the business practices at that client company. ERP is a set of computing that thrives on customization. This might be the sector of the economy which will be among the last to turn away from the 3000 and MPE.
