The process of retrieving data for a file from secondary storage 

(either disk or tape).

S

Small Computer System Interface. The interface that is used to 

talk to most hardware devices such as tape and libraries.

A scalable, high performance, data management solution that 

ensures the long-term safety and recoverability of data in SAN 

environments, while optimizing the use of storage resources. It 

consists of two components, the StorNext Storage Manager 

(SNSM) and the StorNext File System (SNFS).

A SAN is a dedicated, high-performance 

network whose primary purpose is the transfer of data along FC 

or high-speed Ethernet connections between servers, 

interconnect devices, and storage peripherals.

One of the two components that make up 

StorNext. SNFS is primarily used to provide Fibre Channel 

connections (but supports other types of connections) in a 

serverless environment which enables clients to access data and 

share files.

One of several components that make 

up StorNext. SNSM combines the functionality of two products, 

TSM and MSM to provide high-performance file migration and 

management services, and to manage automated and manual 

media libraries, including library volumes.

The process of copying data for a file to secondary storage (either 

disk or tape).

A set of similar storage devices that can be maintained as a 

group.

The Tertiary Storage Manager is 

responsible for policy management and controlling data 

movement between primary disk and secondary storage (either 

disk or tape). 

The process of freeing date blocks stored to secondary 

storage (either disk or tape). The file name remains visible in the 

file system.
