The original legato prestoserve board (VME bus) was manufactured by Micro Memory Inc, 9540 Vassar Ave Chatsworth, CA 91311 818-998-0070 Our contact was Mose' Jadon. The address and phone # are circa 1989. Amazingly enough, a web search turns up http://www.micromemory.com, and the old phone # is still valid. The original board was called the MM6704c by Micro Memory. A design firm we didn't pick wanted a bit under $100,000 for a custom engineering design, plus about $1000 per board. A PCI board is *much* smaller then a 9U VME board, and I'd expect the boards to be a lot cheaper. I think you'd want at least a couple weeks of backup, since if the machine crashes due to a hardware failure, it may not come back up soon, and the NVRAM is logically part of the disks... The original Preserve had 3 NiCd batteries to backup its low power static CMOS memory, good for about 6 months with no power (it also had a built in charger). don To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
