ahh hardware.. my box of joy :) SCSI has been better because of throughput and disk speed until recently... now its more of a simultaneous channels available to speak to either format... the latest ATA stuff is very comparable with SCSI and costs far less.
RAID is an excellent technology for file servers in offices.. online wise it has some performance impact undoubtedly... moreover, your disk wont perform at 100% due to multiple copies and striping info being wrote vs. one file write... People live by RAID... its expensive and fairly a pain in the arse to setup and maintain.. and costly if you are running RAID worth running (see Raid 5)... With a web server you could just copy all files from a CD to a RAM drive in most scenarios... it doesn't get any faster than that.. and it's redundant.... RAID ideally is good for your database box and logging... although it could fall on its own weight of success with all those spare writes... be sure to get a RAID controller with lots of cache... just in case... and it's own battery backup in case of failures... RAID isn't necessary for anything. RAID can go in the server if you have a nice case... those 1Us hold 1-2 drives so forget that... You can run RAID via SCSI off external backplane connector on your server... Additionally, and how I prefer it... you can get RAID in a NAS or SAN solution... see Maxattach from Maxtor.... -paris Paris Lundis Founder Areaindex, L.L.C. http://www.areaindex.com http://www.pubcrawler.com (p) 1-212-655-4477 [finding the future in the past, passing the future in the present] [connecting people, places and things] -----Original Message----- From: Dick Applebaum [mailto:[EMAIL PROTECTED]] Sent: Friday, August 02, 2002 4:19 PM To: CF-Talk Subject: [SOT] Server Hard Drives I am not a server-side person, so maybe some of you who are, can help me. In recent posts, and other times in past posts, people have dismissed Apple's Xserve as not ready for prime time as far as servers go. But, I have heard that Apple boxes (pre-Xserve) have been used for years as servers in Universities, and places like Ford, and some others This confuses me -- does Apple know something that others don't, or vice versa? One comment was that SCSI interface to hard drives is better than ATA IDE interface. Why? Others said that they would not consider hardware for a server unless it had RAID. Why? I can see the desirability of RAID, but: Is RAID necessary for an Application Sever, like JRun? Is RAID necessary for an Web application Sever, like CFMX? Is RAID necessary for an Web Sever, like Apache? Is RAID necessary for a Database Server, like MS-SQL? Do all of the above have the ability of deploying on or taking advantage of a RAID? Do RAIDs normally go in the same box as the server(s) or they just a separate rack-mount component? If separate, how do RAIDs interconnect with the other rack-mount boxes? Finally, what would be the configuration of a good, reliable Web Hosting environment that included all the above servers and RAID, look like?
