Pardon me for continuing to add to a week-old thread, but revisiting the HP
Products pages reminded me of an old and on-going annoyance, hardware that
runs MPE, but you wouldn't know it by looking. In this case, it's the
a-class and n-class servers. Now, I think that when most of us hear these
terms, we think of the latest offerings of the e3000 (among a few other
considerations).

Making the common mistake of going from the home page to products &
services, and on there to servers, if I choose tower servers, I get links to
the e200, e800, lc2000, lh3000, and lh6000, none of which currently work.
(the page you requested has moved). Backing up a couple of pages, I try rack
servers, and I see a-class and n-class, among other classes, all of which
are hp-ux. Are the a and n-class servers rack mounted only? Investigation
indicates otherwise.

Wait, I think I see something that may indicate WHY there is not a single
page for the same hardware, or at least a nearly identical layout for easy
comparison. Well, something besides the processor speed problem in the
a-class e3000. The hp 9000 a-class overview & features page at
http://www.hp.com/products1/unixservers/entrylevel/aclass/ says that it has
6.5TB external disk capacity, rather prominently. A footnote on the hp e3000
a-class specifications page at
http://www.hp.com/products1/mpeixservers/aclass/specs.html says that Maximum
external disk capacity is limited to 12 TB with Release 7.0. Release 7.0
Express 1 will support maximum disk capacities of 37 TB.

I guess if 6.5TB just isn't enough for you, then you probably want MPE. That
just doesn't seem right! OK, let's look at the n-class servers. No, the
n-class e3000 supports the same 37TBs as the a-class e3000, whereas the
n-class 9000 supports 71TB. More differences between essentially identical
hardware, and still no answer to the question, why not a single page for the
single hardware offering?

Looking for some fine print at the bottom, I do notice that:
The N-Class (9000) Outpaces the Competition in Important Industry
Benchmarks. To See How the N-Class Stacks Up Against Comparable Systems,
click the links below.
System Performance Comparisons:
  TPC-C: Transaction Throughput
  SPECint_rate95: Integer Calculation Throughput
  SPECfp_rate95: Floating Point Calculation Throughput
  SPECjvm98: JAVA Virtual Machines

Processor Performance Comparisons:
SPECint95:Single Integer Calculation Speed

I thought benchmarks didn't matter.
