RAID Controllers
A RAID controller, otherwise known as a disk array controller, is a component that increases the number of hard drives that can be used in a server. Benefits of utilizing a RAID controller include larger storage capacities and improvements in I/O performance, scalability, fault tolerance, versatility, and data availability. There are many controllers available on the market, and manufacturers include Fornida, Dell, and HPE. Host bus adapters, while not the same as RAID controllers, are often used together within a system depending on the desired functionality.
RAID controllers are engineered to work with the following hard drives: solid-state drives (SSD), serial attached SCSI drives (SAS), near line SAS drives, and serial ATA drives (SATA). Generally, the types of drives can not be mixed together within the same RAID disk subsystem. Another important note is that the components of a RAID system will need to be
configured at the same data-transfer rate. If a hard drive has a speed of 6GB per second but the adapter only supports a speed of 3GB per second, the system will be limited to 3GB/s.
Depending on the required server solutions, a server engineer will need to determine which "RAID level" to be used. The
different RAID levels are RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60. The numbers indicate a basic set of configurations that employ various techniques in order to create data stores. For example, RAID 1 uses a technique
referred to as disk mirroring that allows data written to a single drive to be written to another drive at the same time. RAID 10, on the other hand, can connect up to 256 drives. With such a wide range of options for server storage and configuration, the possibilities are virtually limitless.
