- Just to rub the point in: the DEC 10000 AXP has:
-
- - 6 processors
- - 2 to 14 GB of ECC RAM
- - up to 4 Futurebus+ IO busses
- - up to 8 FDDI (100 Mb/s network) links
- - up to 56 GB of in-cabinet disk
- - up to 284 GB of directly attached disk
- - up to 10,000 GB of in-cluster disk
- - 800 MB/s "system interconnect"
- - 400 MB/s I/O bandwidth
- - support for HIPPI,CI,XMI,...
- - Integrated Uninterruptible Power System
-
- none of which I would reasonably expect on a desk, this year.
-
- I'm not in the market for this, so I have no idea how it compares to
- its competition. My point is not that this is/isn't a wonderful buy.
- My point is that it is almost never reasonable to compare wildly
- different *systems* by a single metric, such as $/SPECmark. Heck,
- some of the potential customers may ask DEC to price it without the
- floating point units...
