Small Computer System Interface. The interface that is used to

 

S

 

 

 

talk to most hardware devices such as tape and libraries.

 

 

StorNext 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).

 

 

Storage Area Network (SAN) 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.

 

 

StorNext File System (SNFS) 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.

 

 

StorNext Storage Manager (SNSM) 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.

 

 

Store

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

 

 

 

disk or tape).

 

 

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

 

 

 

group.

 

Tertiary Storage Manager (TSM) The Tertiary Storage Manager is

 

T

 

 

 

responsible for policy management and controlling data

 

 

 

movement between primary disk and secondary storage (either

 

 

 

disk or tape).

Truncation The process of freeing date blocks stored to secondary storage (either disk or tape). The file name remains visible in the file system.
