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.
