The 68040 has quite a bit more kick than a 68030. That's a good thing. The 68000 series was always a good line. Plenty of integrated devices use them. > Those of you who insist that their computer is maintained purely Intel will > be glad to know that (as I am told), the next generation will have an i960 > instead. The i960 is not necessarily better. Especially, not the gutless 20mhz version. DPT might be better off with the 68060, as long as the price is right. ... > find the support, the configuration utilities (in native mode!), the > perfomance and the complete integration (You will get a beep, console > output, syslog, SNMP event and a can of diet soda whacked on the head every > time: ... > b.

I don't have a DPT enclosure :(, and it doesn't seem that DPT makes rack mount enclosures. > If you have a spare disk plugged in, you will also get aotomatic re-build > of the array. Oh, did iI mention all power supplies are redundant and all > disks are hot pluggable without any software intervention? Again these all sound like features in the hardware module? I just use standard hot-swap modules (Dataport VI). FreeBSD gets mighty confused when you pull a drive while it is running, but the modules are mighty handle for any kind of field replacement. Are power supplies a big deal these days? I've never had a good PS2 supply die, but have had 4 drives die, all in last three years. Tom
