It was my understanding that Decade, Century, Millenium, etc... were all terms for "levels" of product that were used within multiple product lines, so that a SmartRAID IV "Century" model would be less powerful than a SmartRAID IV "Millenium" model, which might or might not be more or less powerful than a SmartRAID V "Century" model. Comparing <http://www.dpt.com/products/5matrix.html>; against <http://www.dpt.com/products/prod_raid.html>, this seems to bear out. So, when you say "SmartRAID Century", you need to specify which model of SmartRAID Century it is that you're talking about. In fact, when comparing the various different models of SmartRAID V "Millenium" controllers at <http://www.dpt.com/products/5matrix.html>, it is clear to me that you need to be even more specific -- you need to mention whether it's the 32-bit or 64-bit controller, and if it's 64-bit, you need to specify whether it's the Ultra2 SCSI controller or the FibreChannel controller. Of course, you also need to specify things such as how many host channels there are, how much NVRAM there is, etc.... My previous testing was done with the SmartRAID IV PM3334UW controller with 64MB ECC NVRAM and one Ultra-Wide SCSI channel. And you know where that page is. ;-) -- These are my opinions -- not to be taken as official Skynet policy ====================================================================== Brad Knowles, <blk@skynet.be> || Belgacom Skynet SA/NV Systems Architect, Mail/News/FTP/Proxy Admin || Rue Colonel Bourg, 124 Phone/Fax: +32-2-706.13.11/12.49 || B-1140 Brussels http://www.skynet.be || Belgium To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
