The physical implementation of the RAID is almost similar to the implementation of any other normal computer. The RAID may not be essentially any hardware that is used for the implementation of the computer server. But it is the technology that is used for the implementation of the servers that are fault tolerant and provide better infrastructure support to the user. The Hardware involved in the implementation of the RAID includes the RAID controller device. The RAID controller device may be different in different types of the RAID. For example the RAID controller may be different for the IDE RAID, or the controller for the RAID in the case of the SATA may again be different. The RAID controller is also available for the SCSI etc.

The hardware at most apart from the RAID controllers that can be used in the RAID is the normal secondary storage media that is the hard disk. The only difference is that there are usually more than one hard disk drives involved in the implementation of the RAID.

The issue of controllers is the specific for the different types of the RAID. The RAID also has lots of levels. The levels may be either the Single Level RAID or the Multiple RAID Levels also known as the Nested RAID Level. The implementation of the hardware is different in the different levels of the RAID. The software may also be required in the case of any drivers being used for the RAID. The drivers may be even provided for the RAID controllers. The hardware is some what an essential issue as far as the RAID is concerned.

There are many issues that are related to the hardware part of the RAID. The most essential among them are the following that are described below. The description is given by considering the example for any of the RAID devices. The specific example here is the configuration of the hardware of the IDE RAID.

The major issues that can discussed one after the other are as follows: Fault survival, Data integrity, Physical stability and most importantly the performance of the system. The Physical stability of the system is important as the hardware may fail during the implementation of the disk drive. The stability of the system is of utmost importance to the user. The server should be stable so as to provide the support for the other terminals of the network. The fault tolerance is also a property that is associated with the hardware. The server in any case should be able to sustain the damage and provide better understanding to the other subsystems of the network.

The data integrity means that the data sent over the medium reaches the recipient terminal. The data that is sent over from the server should reach the other sub systems of the network. And also the data should be that only which was actually sent. This property is known as the data integrity. The basic reason for the RAID implementation is the performance of the system. The performance cannot be compromised in any situation when the RAID is used as the server. Hence the RAID is considered as the better performer in the implementation of the server over a network. The hardware failure could also affect the performance of the RAID.
