service
A unit of the StorageGRID Webscale system, such as the ADC service, NMS service, or
SSM service. Each service performs unique tasks critical to the normal operations of a
StorageGRID Webscale system.
SQL
Structured Query Language. An industry-standard interface language for managing
relational databases. An SQL database is one that supports the SQL interface.
ssh
Secure Shell. A UNIX shell program and supporting protocols used to log in to a remote
computer and run commands over an authenticated and encrypted channel.
SSL
Secure Socket Layer. The original cryptographic protocol used to enable secure
communications over the Internet. See also,
TLS.
SSM service
Server Status Monitor. A component of the StorageGRID Webscale software that monitors
hardware conditions and reports to the NMS service. Every grid node runs an instance of
the SSM service.
Storage Node
The Storage Node provides storage capacity and services to store, move, verify, and
retrieve objects stored on disks.
storage pool
The element of an ILM rule that determines the location where an object is stored.
storage volume
See
object store
StorageGRID
A registered trademark of NetApp, Inc., used for an object storage grid architecture and
software system.
Task Signed Text Block
A Base64 encoded block of cryptographically signed data that provides the set of
instructions that define a grid task.
TCP/IP
Transmission Control Protocol/Internet Protocol. A process of encapsulating and
transmitting packet data over a network. It includes positive acknowledgment of
transmissions.
throughput
The amount of data that can be transmitted or the number of transactions that can be
processed by a system or subsystem in a given period of time. See also,
latency.
Tivoli Storage Manager
IBM storage middleware product that manages storage and retrieval of data from
removable storage resources.
TLS
Transport Layer Security. A cryptographic protocol used to enable secure communications
over the Internet. See RFC 2246 for more details.
transfer syntax
The parameters, such as the byte order and compression method, needed to exchange data
between systems.
