Feature that atomically writes the same data to two separate volumes, stored on different
physical hardware, before the application receives an I/O complete message. Both writes
either complete or fail, so both volumes are fully synchronized at all times. However, the
feature can increase write latency for the application. See synch.
A private network that Dell AIM uses for communication between the Controller, personas,
and VMRacks. The Controller also uses this network to discover servers and to boot
personas and VMRacks on them.
A BIOS-based program that allows configuration of a system's hardware and customization
of the system's operation by setting features such as password protection. Because the
System Setup program is stored in NVRAM, any settings remain in effect until changed.
A Dell KACE appliance-based deployment management solution for IT professionals that
provides tools for disk imaging, user state migration, remote site management, system repair
and recovery, as well as computer inventory scanning and assessment. Additionally, it
automates pre-and post-deployment configuration tasks such as computer inventory
scanning and assessment; it also automates disk, BIOS, and RAID configuration, software
distribution, and configuration management.
A Dell KACE appliance-based systems management solution for IT professionals that
streamlines tasks such as inventory management, software distribution, reporting, patch
management, asset management, scripting, and service desk support through a web-based
interface.
In the context of Dell AIM, a dormant persona that you can clone to create other personas,
but which you can't run (to prevent changes to the template).
Read-only volume from which you create thin clones.
Volume that shares space with a template volume. Thin clones provide an efficient use of
storage space for configurations with multiple volumes that have a large amount of common
data.
Feature that lets you over-provision (or over-subscribe) the space available in the SAN.
Storage objects (such as volumes) that use thin provisioning report their potential maximum
size to applications, but may actually use much less space. Thin provisioning allows
organizations to reduce their overall storage expenditures, increase availability and achieve
greater performance.
Storage optimization strategy in which data required quickly and often is stored on
expensive, fast media types, and data required rarely is stored on less expensive, slower
media types.
In Dell EqualLogic PS Series arrays, delegated space capacity on the secondary group that
is no longer accessible from the primary group.
A port on a network hub or switch used to connect to other hubs or switches without
requiring a crossover cable.
In Dell EqualLogic Group Manager, to remove a member from a group while the member
remains online.
In Dell Compellent Storage Center, a read-only volume that has been created from a previous
replay, for the primary purpose of recovering data. See Replay.
