FC SAN is made up of several physical and logical components. Such as  Host bus adapters and converged network adapters FC Switches and directors FC Storage Arrays FC Cabling FC Fabrics FC Name Server Zoning FC Addressing FC Classes and Service Virtual SAN   Fibre Channel (FC) SAN Physical Components The key FC SAN physical components are network adapters, cables, and interconnecting...
The next generation IT platform is built on social networking, mobile computing, cloud services, and big data analytics technologies. Applications that support these technologies require significantly higher performance, scalability, and availability compared to the traditional applications. Storage technology solutions that can meet the these requirements  are: Advanced Storage Area Network...
The use of RAID technology started approximately 20 years ago and there are no significant advancements on the RAID technology till last 5-6 years. The common disk drive bloat problems and other disk slow performance issues lead to a longer rebuild times in a disk failure situation. This shows...
A hot sparing refers to a process that temporarily replaces a failed disk drive with a spare  drive in a RAID array by taking the identity of the failed disk drive. When a new disk drive is added to the system, data from the hot spare is copied to...
RAID 6 works in the same way as RAID 5, except that RAID 6 includes a second parity element to enable survival if two disk failures occur in a RAID set. Therefore, a RAID 6 implementation requires at least four disks. RAID 6 distributes the parity across all the disks....
RAID 5 is a versatile RAID implementation. It is similar to RAID 4 because it uses striping. The drives (strips) are also independently accessible. The difference between RAID 4 and RAID 5 is the parity location. In RAID 4, parity is written to a dedicated drive, creating a write...
RAID 1+0 is also known as RAID 10 (Ten) or RAID 1/0. RAID 1+0 is also called striped mirror. It is a hybrid of RAID 1 (mirror sets) and RAID 0 (stripe sets). The objective of this RAID type is to combine both striping and mirroring techniques to get both...
RAID 1 uses the mirroring technique. In this RAID configuration, data is mirrored to provide fault tolerance. A RAID 1 set consists of two disk drives and every write is written to both disks.  These two disks are often referred as mirrored pair and the mirroring is transparent to...
RAID 0 does not offer data redundancy as it does not use parity or mirroring techniques. RAID 0 uses striping technique to store the data without using the parity. The striping means that data is spread over all the drives in the RAID set, yielding parallelism. RAID 0 configuration uses data...
There are different types of RAID levels which we can use in the storage systems. The RAID level selection depends on the parameters such as application performance, data availability requirements, and cost. These RAID levels are defined on the basis of striping, mirroring, and parity techniques. Some RAID levels use...
