I've never bought-in to the mirrored kool-aid - I prefer RAID-5. When cost is an issue, you're going to have bottlenecks. And it's true
that RAID-5 requires a pricier base machine with a more expensive disk controller.
IBM charges more out of country than inside the US (usually). So - be that as it may, you've got a system with a disk bottleneck and no
amount I've said that the smallest 520s IBM sells are vastly underpowered and slow. I didn't say that all System i are underpowered and slow, because I haven't seen anything bigger than a 520. My main point remains, that the system is far too slow for it's price point. A machine for 20k should run circles around a pc server for 10k. But it doesn't. And that's the problem. There are no 32 way PC servers - but I don't care about 32 way.
of CPW will fix that. You can put a 32-way 595 with 1 TB of RAM on 2 arms and you'll be DYING. I'll bet lots of body parts on it. Because I've done it to prove a point.
I've never ever SEEN a 595 (except on pictures). We're from different worlds, it seems.
