I say RAID typically does that, as there are several configurations that offer different solutions to redundancy, but some configurations are not redundant whatsoever.
The number of hard drives required would rely on this configuration chosen, since described afterwards.
I mention the demand for matched hard disks, and although marriage ceremony absolutely vital, it is usually recommended. Most arrays only will be able to use the capacity of the drive, so in cases where a 146 GB 10000 RPM SCSI 80 Pin Hard Drive is included in a simple configuration through an 80GB Hitachi generate, that extra 170GB would probably go to waste.
This type of system may be run on almost any hard drive, including 300GB Hard DISK Drive WITH TRAY . In addition to matching capacities, it is strongly suggested that drives match in terms of speed and additionally transfer rate as the performance with the array is restricted with the weakest get used. One even more area that should be considered even though matching is the type of hard get. SCSI controllers are generally for as well SCSI, SATA, and also ATA exclusively, although some systems make it easy for arrays being operated all around controllers with different types.
The controller is where the data cables in the hard drives are affiliated, and conducts the many processing in the data, like the typical get connections available on a motherboard. SATA controllers are available as add on cards, in this way Silicon Graphic PCI ATA controller, or incorporated into motherboards, like the SATA controller on the Asus K8V SE Deluxe. Motherboards which include the controllers may be operated without use of SATA, nonetheless integration is a nice feature to have if it is a consideration. Perhaps even for systems without on board, the relatively cost effective of add-on cards makes this the main upgrade remarkably pain absolutely free.
