enforce allocated

limit (quota)

An enforced quota for the amount of storage available to a shared folder. An

enforce allocated limit prevents data from being saved to a shared folder once

all the storage space allocated to the shared folder is used.

Exchange storage

group

The fundamental unit of storage management in Microsoft Exchange. Storage

groups consist of Mail stores, Public stores, and log files.

exclusive storage

An Advanced window option that allows you to dedicate a hard drive(s) for

storing data for a specific application component or shared folder.

file system

A method for storing and organizing computer files and the data they contain to

make it easy to find and access them.

hot spares

An Advanced window option that allows you to reserve one or two hard drives

as spares. A hot spare is a hard drive reserved as a spare for storage space

configured as RAID 1, RAID 1+0(10), or 5. A hot spare automatically replaces

a hard drive when it fails.

iSCSI

Internet small computer system interface. Like an ordinary SCSI interface, iSCSI

is standards-based and efficiently transmits block-level data between a host

computer (such as a server that hosts Exchange or SQL Server) and a target

device (such as an HP All-in-One Storage System). By carrying SCSI commands

over IP networks, iSCSI is used to facilitate data transfers over intranets and to

manage storage over long distances.

ASM works with the Microsoft iSCSI Target, which builds the iSCSI infrastructure

on application servers with data hosted on your HP All-in-One Storage System

and on your HP All-in-One Storage System so that application data is stored on

your HP All-in-One Storage System.

iSCSI LUN

A type of LUN (logical disk) created on an application server by ASM when a

storage-allocation wizard is ran to host application storage. When application

storage is hosted using ASM, all storage communication passes through the

iSCSI LUN on the application server to the LUN on your HP All-in-One Storage

System. This allows data saved by the application to the iSCSI LUN on the

application server to be transparently stored on your HP All-in-One Storage

System instead.

log file

The component of a Microsoft Exchange storage group or a Microsoft SQL

Server database that contains log data.

logical disk

Also known as a LUN. A logical disk contains one or more volumes and spans

multiple hard drives in an array. RAID configuration of storage is performed at

the logical disk level.

LUN

Also known as a logical disk. ASM will grow a LUN (make it larger) when the

LUN requires more of the storage space on an array.

Mail store

The component of a Microsoft Exchange storage group that contains mailbox

data.

Menu bar

The horizontal menu located at the top of the ASM user interface. The menu bar

is the Microsoft Management Console menu bar; ASM is a snap-in hosted by

the Microsoft Management Console.

MMC snap-in

Microsoft Management Console snap-in. An application added to the Microsoft

Management Console. All-in-One Storage Manager is a MMC snap-in.

NAS

Network-attached storage. This term is used to refer to a specialized type of

file server. The HP All-in-One Storage System provides NAS storage as well

as iSCSI storage.
