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 Description

This section can be expanded or collapsed by clicking Expand menu and Collapse menu.

In 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.

    If a system is managed by HP Storage Essentials, it does not show the SMI subtype.

  • 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.

Some vendors enter firmware details in the Software Version and Software Manufacturer fields instead of the Firmware Version and Firmware Manufacturer fields. These fields might display data about any software related to the system.

If this storage array is managed by HP Storage Essentials, data is not displayed for the Product Name, Product Vendor, Product Identifying Number, and Product Version.

Ports

This section can be expanded or collapsed by clicking Expand menu and Collapse menu.

If 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 Details

  • Element Name. The name of the controller.

  • LUN Count. The number of connections made through this controller.

  • Status. The controller's WBEM operational status. Refer to System Table View Page - WBEM Operational Status Types for additional information about WBEM status.

Click Expand menu to view specific port details.

Port Details

Storage Volumes

This section can be expanded or collapsed by clicking Expand menu and Collapse menu.

This 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:

    Package RedundancyData RedundancyRAID Level
    01RAID 0
    11RAID 5
    12RAID 1
    21RAID 6
    22RAID 15/51

    If the RAID value is calculated by HP Systems Insight Manager, an asterisk is added to the RAID value, for example RAID 5*.

Capacity Information

This section can be expanded or collapsed by clicking Expand menu and Collapse menu.

The 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.
