Hi, I've been digging around the archives, and thought I'd see what people have to say now that support for these controllers has been around for some time. I'm focusing on the Mylex and AMI products. I'll start with Mylex as it's a much shorter list. Mylex ----- (light load) AcceleRAID 150 - low end model, 33MHz i960 processor, max 16MB cache. I assume one would only want to use this in a very light-duty machine. About $380 mail order. AcceleRAID 250 - Discontinued. (heavy load) ExtremeRAID 1100 - lowest high-end model, 230MHz StrongARM processor, up to 64MB cache. At the moment, this appears to be the only real choice in the mylex family for a server with significant load. Others - there are beta drivers on Mike Smith's site (http://people.freebsd.org/~msmith/RAID/index.html), but I'm limiting this to stuff that's been in the field for a while. AMI --- Booting off these looks to have been introduced in 4.1. I assume these are relatively well tested. I do not believe there is a command-line utility for these, so remote notification of failures may be difficult. (light load) MegaRAID 100 - super cheap, $340 mail order, 33 MHz i960, up to 128MB cache. MegaRAID 200 - ditto, $460 mail order, not really sure what else you get, specs look the same... MegaRAID 300 - ditto, $550?? (unable to find pricing online), again, very similar but with a 100MHz i960. Perhaps this would be OK for a medium-duty server? (heavy load) Elite - Seems to be discontinued, not available at any of AMI's listed online outlets Enterprise 1400 - Cheaper than the mylex at $980, i960 at 66MHz, 3 channels, battery backup for cache. Enterprise 1500 - Similar to above, $1150, i960 at 100MHz, 4 channels, battery backup included. So what have people chosen so far? It seems for a small machine that needs critical data protected by raid, the AMI 300 would be a good choice on a low budget, but on the high end it seems the Mylex ExtremeRAID is the better choice... Anyone with any real experience with these products, please comment... Thanks, Charles To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
