I've already scrapped together a box, power supply, # ram, an adaptec scsi card and a 18 gig 10,000 rpm seagate cheetah # scsi drive. The plan is to make this drive the data partition that # hold all the websites and any data destined to be requested by the # end users. Makes sense... # I want to install a large IDE drive to be used for backups in addition # to a Sony tape drive that will be attached to the box. Okay... a large IDE drive should be more than enough for storing archives or a temp storage before you archive the stuff. # Now my question... For the drive that will hold FreeBSD itself, am I # defeating the purpose of the scsi drive by installing a 7,200 rpm IDE # drive and using that as the OS drive? This is where I can save some # money and have room to play with by going with IDE over SCSI. I have several FreeBSD servers that run off of 7200RPM IDE hard drives (I just make sure that I choose a manufacturer that is known to have the _least_ issues and one that lasts a long time). The only time I use SCSI hard drives in a FreeBSD server is if the server only has hot-swappable SCSI bays (like the Compaq DL360 for instance). For the OS, an IDE drive will do fine. If you are really concerned about redundancy, you can get a hardware IDE RAID controller and do a RAID 1 over two drives (which mirrors one drive to another... meaning that you need to get two identical IDE drives). # That would give me three drives: # 1 smaller and fast 7200 IDE for the OS # 1 Fast SCSI for data # 1 IDE for backups in addition to the tape drive. Or 2 7200RPM IDE drives if you decide to RAID 1 (ie: mirror) the drives for redundancy and possibly improve read performance by a hair (or a hare, depending on what is being read from the drives). -- Linh Pham [lplist@closedsrc.org] // 404b - Brain not found To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
