Principles of RAID
I say RAID typically does the following, as there are plenty of configurations that come with different ways to redundancy, however, many configurations are not redundant whatsoever.
The number of hard drives required would rely on the particular construction chosen, since described in the future.
I mention the demand for matched hard drives, and although this is not absolutely vital, it is usually recommended. Most arrays will still only be ready to use the capability of the tiniest drive, so when a 146 GB 10000 RPM SCSI 80 Pin Hard Drive is included in a simple configuration with the 80GB Hitachi get, that increased 170GB would probably go to help waste.
This type of system may be run on almost any hard drive, including 300GB 15000RPM Hard DISK Drive WITH TRAY . Apart from matching capabilities, it is immensely important that propels match with regard to speed and transfer rate for the reason that performance in the array is restricted by the weakest generate used. One even more area that needs to be considered while matching is the kind of hard drive. SCSI controllers are typically for either SCSI, SATA, and also ATA exclusively, although a few systems make it easy for arrays to be operated across controllers of different formats.
The controller is where the data cables in the hard propels are affiliated, and conducts the different processing with the data, like the typical get connections entirely on a motherboard. SATA controllers are obtainable as increase cards, this way Silicon Image PCI ATA controller, or built-into motherboards, like the SATA controller found on the Asus K8V SE Deluxe. Motherboards offering the controllers can be operated without the use of SATA, nevertheless integration is a nice feature to have if it is mostly a consideration. Perhaps even for solutions without on board, the relatively cost effective of add-on cards helps make this the main upgrade remarkably pain free.
