Re: [WinMac] Hardware RAID for Macs

John,

I think Dan's sticking point here (I just had this argument with him) is
that these are all SCSI-SCSI hardware bridges. With these you have to
stick the appropriate PCI SCSI card in your mac - these arrays look like a
single SCSI ID to your mac's PCI card. As opposed to say a Compaq 2SL
controller which *is* the RAID controller and it lives in a PCI slot.

We have a SCSI/SCSI hardware array and are running two ASIP servers off of
one multi-host RAID array. Works very well in fact. Have two basically
empty B&W G3's with LVD SCSI cards and memory in them. Matter of fact,
last weekend we upgraded to these from 9650's - all we had to do was
upgrade the OS on the boot partitions and plug in two servers. Took about
a half an hour.

I've had about 250 macs in & out of here in the past 15 years and with the
exception of the Mac Plus (and maybe a laptop or two) can't ever recall
replacing a power supply. I've replaced about a dozen PC power supplies.
Both of our Compaq 1600 power supplies have been replaced - but I suppose
that's how they scare you into buying the $600 redundant PS upgrade! :-)

I still think it's unfounded for people to be scared away from Apple
hardware for serving. OK, if somebody posts, "I was thinking of building
up an array of six B&W G3 web servers and dropping them off at Exodus on
the way home. Hope they work forever." OK, *that* might make me cringe.
:-)
