HP StorageWorks All-in-One Storage System user guide (440583-005, February 2008)

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.
Navigation pane The left pane in the main window of the ASM user interface that allows you to
quickly navigate between HP All-in-One Storage System Management
applications.
NFS Network file system. The protocol used in most Unix environments to share folders
or mounts. The Create a Shared Folder Wizard does not create NFS shares, but
NFS shares can be created using the Shared Folder MMC snap-in.
percent full
warning threshold
Percentage of capacity for a storage area (storage allocated to an application
component or shared folder) at which an alert is generated. This alert is displayed
in the Content pane and sent to the Windows Event Log. See
Setting a percent full warning threshold on page 74 for more information.
Public store The component of a Microsoft Exchange storage group that contains public folder
data.
RAID Redundant array of intelligent disks. Two or more hard drives configured to
provide a storage with resilience to hard drive failure through the use of RAID
striping and parity disks.
RAID level See Table 20 on page 73 for RAID level descriptions.
RAID striping Writing data to hard drives in an array by interleaving bytes or groups of bytes
across the multiple hard drives. This allows more than one disk to be read from
or written to simultaneously, which increases the performance.
RAID stripe size The number of bytes or kilobytes of data in a RAID stripe (block of data).
restore To recover lost data using a backup.
revert To return stored data to a previous state using a snapshot.
scaling Changes the display proportions of application component and shared folder
storage in the Content pane. You can choose to scale by the size (capacity) of
the application component and shared folder's storage space, or scale them all
the same. To change the scale setting, select Tools > Options.
size The amount of storage that ASM allocates and configures for an application
component or shared folder. To change the size of the allocated storage for an
application component or shared folder, select the application component or
shared folder in the Content pane and then select Allocate Space in the Actions
pane.
snapshot A read-only copy of a volume at a specific point in time. Unlike a backup, data
is not copied to any media during a snapshot. Instead, when a file is modified
after a snapshot is created, the new updates are written to a new location. The
file-system maintains records and pointers to keep track of the snapshot data and
file changes. A snapshot takes less than a second to create.
