Ok, 1U and 4U are just shorthand, to describe the thicknesses of the individual computers and other appliances in a rack. I think, off the top of my head, that 1U represents about 1 3/4" of height. Looking at the rack in the photo, and starting at the bottom... The thin 1U at the bottom is a SuperMicro server, dual PIII 1,000 MHz CPU's, and 1 gig RAM, named supermicro.robertwittig.net. It is home to four websites, robertwittig.com, robertwittig.net, robertwittig.org, and no-friction-cafe.com, and handles email for those four domains. It is running OpenBSD 3.9 operating system. The 1U server above it, is not running... it is a back-up computer, that is configured the same as supermicro.robertwittig.com, and can be put on-line when needed, if/when the main server requires maintenance. The white 4U computer above it is a Desktop machine, running FreeBSD 6.0 at the moment, but with removable hard drive cages, it also runs an OpenBSD Desktop installation. Basically, it is a 'practice box', where I test things before putting them 'live' on a working machine, and for learning and studying things. Above that, sits a small 1U power panel, to protect against power surges. Also, on the floor behind the rack, is a UPS (Uninterruptable Power Supply) so that the servers and other machines can be shut down properly, in the event of a power failure. On top of the power panel, is a 1U Compaq KVM switch, so that I can control the array of computers from a single Keyboard, Video array, and Mouse. Above that, the blue Netgear ethernet hub, to connect all the computers to the Internet... there is a single cable running up to the attic workshop from the DSL modem/router, which is in my office, downstairs, along with my two main computers... this Red Hat machine I am typing on now, and a Windows 2000 Graphics Workstation. Above that, the black 4U machine, is a Windows 2000 file server, and is connected to the Compaq SCSI array. I picked that up, along with about 50 SCSI drives, when the University of Chicago was upgrading their servers last winter, for the cost of carfare down there and back, and the muscle to lug the huge, heavy suitcase-with-wheels across Chicago on public transit in the dead of winter. The Skeletek frame cost me $90.00 on eBay, from a store here in Chicago. -- -wittig http://www.robertwittig.com/ . http://robertwittig.net/ . http://robertwittig.org/ To unsubscribe from this list, please email [EMAIL PROTECTED] & you will be removed.
