The N-class server is a fast, affordable, mid-range and high-end system with up to 35 percent more power than its highest performing predecessor -- the 12-way 997 server. It offers 220, 330, 440 and 550 MHz processors, up to 4-way multi-processing, and supports up to 16 GB of memory.
I installed our test suites and ran all of our tests in a fraction of the time it takes to run our test suites in our lab at our home office in Surrey BC. This was done without changes to our software, a recompile, nothing.
In fact the NM version of our test suite typically takes 80 minutes on a 968 LX with no users. On the new N-Class server I was using the test suite took only 15 minutes.
This is a huge time savings.
I did some custom tests extracting 5Gb of data, sorting and outputting the data. While watching the process with Glance I saw IO rates exceeding 400 IO's per second. Previous to this testing, the highest rates that I saw on a customer's 997-4 way was approximately 95 IO's per second. The N-class testing was done with the files "fflushed" from memory to ensure that we stressed the IO subsystem as much as possible.
One of the most impressive tests was the reading and output of a 5Gb dataset, with the comparison a 10 byte key value using Suprtool's Table feature, with all 5Gb of data selected. It was done in 6 minutes 38 seconds. With the faster memory and processors of late the new PCI IO brings IO rates more in line or balanced with the system as a whole.
These were some of the fastest HP e3000 servers I have ever seen, and this new technology extends the performance curve beyond anything I had ever imagined for the HP e3000.

"The day we did testing, we hit it with the Web applications," said Goode, who joined the university in 1976 as an analyst and programmer. "You could easily bring down the 979 if you overburden it. The N-class kept going; we never did have to reboot it. It kept responding. Cameron bought its first 3000 in 1975. I came aboard here in 1976 and we are still using programs we wrote in the mid-1970s. And with all the upgrades we've had to do, there's was only one time we had to recompile every program," Goode said. "It's always just been a matter of doing a full backup, installing the new system and reloading. We've always been able to get up and going in a weekend. We've always been extremely pleased with its upward compatibility. It's given us a lot of value and where we are a state-funded college, we don't have a lot of money. (The e3000s) just don't break." .
