Fast enables the customer to create storage pools with heterogeneous device classes (Flash, SAS, and NLSAS) and will place the data on the class of devices or tier that is most appropriate for the block of data. Storage pools allocate and store data in 1 GB slices, these slices…

Explanation

Fast enables the customer to create storage pools with heterogeneous device classes (Flash, SAS, and NLSAS) and will place the data on the class of devices or tier that is most appropriate for the block of data. Storage pools allocate and store data in 1 GB slices, these slices can be migrated or relocated allowing FAST to reorganize LUNs onto different tiers of the pool seamlessly to the hosts accessing the LUNs.
