operations necessary to execute them.
Network File System
In NAS, a distributed file system and its associated network protocol originally developed
by Sun Microsystems Computer Corporation and commonly implemented in UNIX systems,
although most other computer systems have implemented NFS clients and/or servers.
Abbreviated NFS. The IETF is responsible for the NFS standard.
Partition
1. Subdivision of the capacity of a physical or logical disk. Partitions are
consecutively numbered ranges of blocks that are recognized by MS-DOS,
Windows, and most UNIX operating systems.
2. Synonym for the type of extent used to configure arrays.
3. A contiguously addressed range of logical blocks on a physical media that is
identifiable by an operating system via the partition’s type and subtype fields. A
partition’s type and subtype fields are recorded on the physical media and hence
make the partition self-identifying.
Primary Storage Concentrator
The Storage Concentrator that manages the mirror volume.
Promote Image
Promoting a mirror image makes it a stand-alone volume. The promoted volume does not
retain any mirrored volume information but contains an exact copy of the data at the time of
promotion. The new stand-alone volume is accessible to the hosts and can retain security
information from the mirror volume.
Partitioning
Presentation of the usable storage capacity of a disk or array to an operating environment in
the form of several logical disks whose aggregate capacity approximates that of the
underlying physical or logical disk. Partitioning is common in MS-DOS, Windows, and
UNIX environments. Partitioning is useful with hosts that cannot support the full capacity of
a large disk or array as one device. It can also be useful administratively, for example, to
create hard subdivisions of a large logical disk.
Path
The access path from a host computer to a storage device.
