Mirrored Os; Ndmp; Network; Node - American Megatrends StorTrends 1100-P User Manual

Mirrored OS

AMI has added Mirrored operating system (OS) capabilities to the StorTrends® iTX
software in the 2.1 version release. Mirroring the StorTrends® iTX OS is the ability to
install the StorTrends® iTX software on two hard disk drives. Basically, if one of the two
boot hard disk drives fails, you still maintain the ability to boot to the StorTrends® iTX
operating system from the alternate hard disk drive.
NAS
Network Attached Storage. Basically, an appliance that is purposely built as a networked
storage device and meant to be easy to set up, configure, and use. Suitable for file-based
applications. Limitations includes, inefficient provisioning, NAS head becomes the
bottleneck and the point of failure, adding capacity creates complexity, and no block-
level file support.

NDMP

Network Data Management Protocol. It is the industry standard network based tape
backup protocol. The data can be backed up and restored using any NDMP compatible
backup software.

Network

A group of two or more computer systems linked together.
NIC
Network Interface Card. Commonly as a network adapter or network card.
NIS
Network Information System. Developed by Sun™ Microsystems, NIS is a distributed
naming and directory service originally called Yellow Pages™ or YP. It is a mechanism
for identifying and locating network objects and resources. It provides a uniform storage
and retrieval method for network-wide information in a transport-protocol and media-
independent fashion.
NIS is a network naming and administration system typically used for smaller networks.
Using NIS, each host, client or server in the system has knowledge about the entire
system. A user at any host can get access to files or applications on any host in the
network with a single user identification and password. It is intended for use on local
area networks. NIS uses the client/server model and the Remote Procedure Call (RPC)
interface for communication between hosts. NIS consists of a server, a library of client
programs, and some administrative tools. NIS is often used with the Network File System
(NFS). NIS is a UNIX® system-based application.

Node

A processing location. Can be a computer or some other device, such as a printer. Every
node has a unique network address.
