RAID Recovery - Thin provisioning
Thin provisioning, a process of increasing the efficiency, helps utilizing the available space in storage area network (NAS). TP operates disk storage in a flexible manner among various users that is based on minimum space requirement of users.
In previous years, systems required large storage space pre-allocated in it because of the complexity and impact of increasing volume space. On the contrary, Space in the traditional storage provisioning model has been allocated much more than current requirements by assuming the increasing demands as well as growing data complexity. Fat storage provisioning is another name of storage provisioning model. But users don’t prefer using this because of the excessive storage space. According to them, after paying large amount for it, space cannot be utilised. Although, these problems in TP have been resolved now. Some additional advantages it has offered including reduced electric energy consumption and reduced heat generation in comparison to conventional network storage system. The organizations can purchase the less storage according to the requirement and can upgrades the capacity for further business usage. This way they can save the operating cost.
Over-allocation:
Over- allocation is a mechanism that permits server to be kept large storage capacity that actually has been physically reserved on the storage array. It helps growing and shrinking the application storage volume flexibly. Physical storage capacity is only devoted when data is written by the application.
Practically, a storage manager needs to check out how much of the actual storage space has been occupied. Depending upon the requirement, manager can add disks, tapes and solid-state drives in order to increase the storage capacity.
This modern technology was first introduced in 2001 through DataCore software’s SANsymphony 5.0 to the hardware independent storage virtualization platform.
