Storage Area Network is well organized interconnection of storage devices connected via LAN or WAN to cater the need of high speed data transmission. By using this technology a person can access the data stored on a storage arrays located at distant places from the Internet. SAN uses optical fiber cable communication for faster data movement as compared to other conventional methods. SAN also supports Data backup, Data Mirroring and Data sharing among different SAN as well as different servers. Thus offers a unique reliable method of data security at reasonable cost. In this article I will let you know about the latest features introduced in the SAN products.
Latest features of SAN:
Data De-duplication: Recently a new feature is added in SAN products which eliminate the replicated data entered by the user. It works in two ways: In-line or Post process. In-line system lie between the path of host and target so that whenever a request for data storage is sent from the user, data is thoroughly examined and analyzed for duplicate content by the In-line systems and if found then data is deleted before it is written on the disk. Whereas the Post Process system works after the data is stored. Both have the potential to reduce the data space up to 30 to 60 % of the total size.
Thin provisioning: This feature of SAN product improves the storage utilization with the reduced capital cost. Thin provisioning allows a storage element to present more capacity to the concerned user/hosts than the available physical memory. Raw capacity is added whenever it is required by attached host servers. But a consistent monitoring is required to regulate the storage arrays capacity for fulfilling the services requested by the hosts.
Spin down technology: Spin down technology involves the rotation of storage arrays according to their active period (the time for which the concerned drive is in use). When they are not in use then the storage arrays are spin down to reduce power consumption. Now SSDs (Solid State Storage Devices) are being employed as storage elements. SSD is a semiconductor based memory which consumes less power as compared to the conventional memory. SSD gives better performance and less noisy as compared to the conventional mechanical drives.
Unlimited Storage: By using SAN a user can store unlimited amount of data on storage device available SAN and thus don't need to confine yourself to the limited amount of storage attached to your computer.
Improved Performance: SAN performance is not influenced by the constraints like Ethernet traffic or local disk throughput. Data transmitted between the host/user and storage device on the SAN is on its own private network separated form user traffic, backup traffic etc.
Data Security:SAN utilizes RAID technology for data storage thus ensures maximum data security. RAID technology creates multiple replicas of same data at different storage disk so that if one of the disks fails then data can be recovered from another.
Dynamic Storage management:SAN provides authority to create or destroy or resize storage partition according to need. Even the data stored on the storage elements can be translated from one server to another easily.
Thus SAN offers a better option of on line storage as compared to the conventional methods.

They also provide windows maintenance tools for enhancing the speed and performance of computer.
