Glossary
CIFS (Common Internet File System)
A network file system access protocol originally designed and implemented by Microsoft
Corporation under the name Server Message Block (SMB) protocol, and primarily used by
Windows clients to communicate file access requests to Windows servers. Today, other
implementations of the CIFS protocol allow other clients and servers to use it for
intercommunication and interoperation with Microsoft operating systems.
Cluster
A collection of computers that are interconnected (typically at high-speeds) for the purpose of
improving reliability, availability, serviceability and/or performance (via load balancing). Often,
clustered computers have access to a common pool of storage, and run special software to
coordinate the component computers' activities.
Collision
The result of two devices transmitting signals at the same time on the same channel, usually
resulting in a garbled transmission.
Command View NAS Web Interface
A web interface for the storage array that lets you manage the storage on the array, monitor the
status of the arrays, perform array diagnostics, and download new firmware.
Community string
The SNMP keyword required for network management tools to retrieve operational or
configuration information from the device.
Credentials
A user's account name and password.
Daemon
A program that performs a housekeeping or maintenance utility function without being called by
the user. A daemon sits in the background and is activated only when needed, for example, to
correct an error from which another program cannot recover.
DHCP (Dynamic Host Configuration Protocol)
Software that automatically assigns IP addresses to client stations logging onto a TCP/IP network.
It eliminates having to manually assign IP addresses, and it allows a larger group of machines to
share a limited pool of addresses, assuming not all machines are on the network at the same time.
DHCP can assign a new address to each machine at startup (dynamic) or permanent (static)
addresses can be assigned. Newer DHCP servers dynamically update the DNS servers after
making assignments.
Domain (NT)
A group of computers that share a common domain database and security policy.
