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 Storage Server). 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 Storage Server and on your
HP Storage Server so that application data is stored on your HP Storage Server.
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 Storage Server. This
allows data saved by the application to the iSCSI LUN on the application server
to be transparently stored on your HP Storage Server 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.
