We also have 3 SNFs (same as DNF but with no support circuitry for the
2nd CPU) with 128MB and 2940UWs hooked to striped dual Seagate 15150Ws
(4.3GB per). One motherboard is still in the box, but the other two have
been running NetBSD in a production environment for about a month with
no problems. They are definitely much faster than P5-166s (an example
compile went from 908 seconds down to under 500 seconds).

As with another respondent, we've noticed that memory write times are
actually *slower* than a P5-166, while read times are twice as fast.

Wish I'd known about the DNE when we got our SNFs. It's a real pain
finding cabinets they can fit into. Does the DNE also have 8 RAM
sockets? Same number of PCI slots (4)?
