A storage array is a disk array that uses a Fibre Channel controller
to connect to a storage area network (SAN). Additional links are available
on the System Page to access detailed information when
a storage array is selected. Included here are the areas that are unique to
storage arrays. HP SIM displays data supplied by the array's SMI-S provider. If the SMI-S provider does not supply data for a particular
property, the property does not appear on this page. Refer to System Page - Identity Tab for Servers for additional
information about the tab.
The Ports, Storage Volumes, and Capacity Information sections show the
date, time, and duration of the last data collection task. If you want to
update the data, click the Last Update link, and schedule
or run a Data Collection task. Refer to Administering Systems and Events - Data Collection for additional information about data collection tasks.
If this storage array is managed by HP Storage Essentials, the Ports, Storage
Volumes, and Capacity Information sections
do not appear on this page, and an SE System Properties link
appears in the Storage Essentials Pages section on the Tools
& Links tab. Click the SE System Properties link
to view the Storage Essentials device page for this storage array.
Product DescriptionIn addition to the Product Description information on the System Page - Identity Tab for Servers, this section might include: System Subtype. Storage systems use the following
subtypes:
Storage. A system that is identified
as part of the storage infrastructure.
SMI. A system that was discovered through
an SMI-S provider.
Storage Essentials Managed. A system
that is managed by HP Storage Essentials.
Product Name. The product name for the array,
for example, a model number. Product Vendor. The storage array vendor. Product Identifying Number. A unique identifier
for the storage array, for example, a serial number. Product Version. The array product version. Firmware Version. The installed firmware version. Firmware Manufacturer. The firmware manufacturer. BIOS/FCode Version. The installed BIOS/FCode
version. BIOS/FCode Manufacturer. The BIOS/FCode manufacturer. Management Proxies. The server(s) that manage
the selected array through a management protocol, such
as WBEM. Software Version. The version of the software
installed on this system. Software Manufacturer. The manufacturer of
the software installed on this system.
PortsIf HP Systems Insight Manager has discovered controllers that manage
this array's ports, they will be displayed as expandable elements in the Ports table.
If no controllers were discovered, the table lists only port details. Controller DetailsPort Details
Storage VolumesThis section lists the array's storage volumes. Storage volumes are
logical volumes on an array, for example, LUNs. Volume Name. The storage volume name. Visible to Host(s). The storage volume is accessible
to the listed host(s). Block Size. The storage volume's block size
in bytes. Number of Blocks. The total number of blocks
on the storage volume. Total Size. The storage volume's total size. RAID Level. The RAID level of the storage volume.
Typically, this value is supplied by the array's SMI-S provider. If the SMI-S
provider does not supply a value, HP Systems Insight Manager calculates the
RAID level based on the values for Package Redundancy and Data Redundancy
as follows: If the RAID value is calculated by HP Systems Insight Manager,
an asterisk is added to the RAID value, for example RAID 5*.
Capacity InformationThe Capacity Information table lists the hierarchy of available capacity
metrics for storage arrays in the Metric column, and
the corresponding disk space value in the Size column.
For each metric, the disk space value is expressed as a percentage of the
array's raw capacity in the Percentage of Raw Capacity column. Raw
Capacity, the total capacity of the array, is divided into space
that is Un-Allocated and Carved for LUNs.
Space that is carved into LUNs is divided into RAID Overhead, Usable
bytes assigned to Ports, and Bytes not yet assigned to
Ports. The metrics in the Capacity Information table are also displayed as
percentages in a pie chart below the table. If any value in the table shows
an Undetermined value, the pie chart is not displayed. Un-Allocated. The total amount of storage on
the array that has not been configured. Carved for LUNs. The total amount of configured
storage on the array, including RAID overhead. For example, if 100 gigabytes
(GB) is allocated for a RAID-1 (mirrored) storage volume, 50 GB will be usable
by the end-user, 50 GB is considered RAID overhead, and 100 GB is considered
carved for LUNs. RAID Overhead. The total amount of storage
on the array that is not directly usable because it is being used to provide
redundancy. Usable bytes assigned to Ports. The total amount
of configured and usable storage on the array that is connected through one
or more ports. Usable bytes not yet assigned to Ports. The
total amount of configured and usable storage on the array that is not connected
through any port. Users cannot access this storage until it is assigned to
a port.
