mini-port driver
The Windows driver type used for connecting to the Enterprise Virtual Array through the
SAN fabric.
mirrored caching
A process in which half of each controller’s write cache mirrors the companion controller’s
write cache. The total memory available for cached write data is reduced by half, but the
level of protection is greater.
mirroring
The act of creating an exact copy or image of data.
node port
A device port that can operate on the arbitrated loop topology.
NSC
Network Storage Controller. The HSV Controllers used by the Enterprise Storage System.
OSM
Open SAN Manager. A centralized, appliance-based monitoring and management interface
that supports multiple applications, operating systems, hardware platforms, storage
systems, tape libraries, and SAN-related interconnect devices. It is included and resides on
the management appliance, a single aggregation point for data management.
password
A security interlock whose purpose is to allow:
■ A management agent control of only certain storage systems
■ Only certain management agents control of a storage system
physical disk
A disk drive mounted in a disk drive enclosure that communicates with a controller pair
through the device-side Fibre Channel loops. A physical disk is hardware with embedded
software, as opposed to a virtual disk, which is constructed by the controllers. Only the
controllers can communicate directly with the physical disks.
The physical disks, in aggregate, are called the array and constitute the storage pool from
which the controllers create virtual disks.
physical disk array
See array.
port
A Fibre Channel connector on a Fibre Channel device.
port_name
A 64-bit unique identifier assigned to each Fibre Channel port. The port_name is
communicated during the login and port discovery processes.
