Access Control List (ACL)
A list that controls which hosts have access to which volumes. When a host attempts to log
in, the Storage Concentrator requests authorization and allows access based on the list.
Access Path
The route used by a computer to communicate with a storage device. The path accesses the
host bus adapter, host storage interconnection controller and logical unit. Some
configurations support multiple access paths to a single device.
Administrative Interface
The graphical administrative interface is accessed from a computer on the network via a
web browser. The following functions are available through the interface: Storage
Concentrator discovery, physical resource management, storage pool management, logical
volume management, target management, Access Control List management (ACL), system
management, session management.
Adaptive Load Balancing
A feature that allows for more than one networking path providing port FailOver protection,
as well as increased bandwidth. If one port goes down, the other port automatically accepts
the additional load. There is no interruption in server operation, and a network alert is
generated to inform IT staff of the problem.
Application Programming Interface (API)
The interface used by an application program to request services; usually denotes interfaces
between applications and the software components that comprise the operating environment
(e.g., operating system, file system, volume manager, and device drivers).
Array or Array Configuration
A storage array, i.e., a disk array or RAID array.
1. Assignment of the disks and operating parameters for a disk array. Disk array
configuration includes designating the member disks or extents of the array and the
order in which they are to be used, as well as setting parameters such as stripe
depth, RAID model, cache allowance, spare disk assignments.
2. The arrangement of disks and operating parameters that result from such an
assignment.
Asynchronous I/O Operation
An I/O operation whose initiator does not await its completion before proceeding with other
work. Asynchronous I/O operations enable an initiator to have multiple concurrent I/O
operations in progress.
