HP StorageWorks 2300 Modular Smart Array reference guide 19
NOTE: This release has no functions that require Advanced or Diagnostic access; a Standard user can
access all functions.
• WBI Access. Allows access to the web-based management interface.
• CLI Access. Allows access to the command-line management interface.
• FTP Access. Allows access to the file transfer protocol interface, which provides a way to download
logs and install firmware updates.
• Base Preference. The base for entry and display of storage-space sizes. In base 2, sizes are shown as
powers of 2, using 1024 as a divisor for each magnitude. In base 10, sizes are shown as powers of 10,
using 1000 as a divisor for each magnitude. Operating systems usually show volume size in base 2.
Disk drives usually show size in base 10. Memory size is always shown in base 2.
• Precision Preference. The number of decimal places (1–10) for display of storage-space sizes.
• Unit Preference. Sets the unit for display of storage-space sizes. The Auto option lets the system
determine the proper unit for a size. Based on the precision setting, if the selected unit is too large to
meaningfully display a size, the system uses a smaller unit for that size.
• Temperature Preference. Specifies to use either the Celsius scale or the Fahrenheit scale for temperature
values.
• Auto Sign Out. Select the amount of time that the user's session can be idle before the user is
automatically signed out: 5, 15, or 30 minutes, or never.
• Locale. The user’s preferred display language, which overrides the system’s default display language.
Installed language sets include Chinese-simplified, Chinese-traditional, Dutch, English, French,
German, Italian, Japanese, Korean, and Spanish.
NOTE: To secure the storage system, set a new password for each default user.
About vdisks
A vdisk is a "virtual" disk that is composed of one or more disks, and has the combined capacity of those
disks. The number of disks that a vdisk can contain is determined by its RAID level. All disks in a vdisk must
be the same type (SAS or SATA, small or large form-factor). A maximum of 16 vdisks per controller can
exist.
A vdisk can contain different models of disks, and disks with different capacities. For example, a vdisk can
include a 500-GB disk and a 750-GB disk. If you mix disks with different capacities, the smallest disk
determines the logical capacity of all other disks in the vdisk, regardless of RAID level. For example, if a
RAID-0 vdisk contains one 500-GB disk and four 750-GB disks, the capacity of the vdisk is equivalent to
approximately five 500-GB disks. To maximize capacity, use disks of similar size. For greatest reliability,
use disks of the same size and rotational speed.
Each disk has metadata that identifies whether the disk is a member of a vdisk, and other members of that
vdisk. This enables disks to be moved to different slots in a system; an entire vdisk to be moved to a
different system; and a vdisk to be quarantined if a disk is detected missing.
In a single-controller system, all vdisks are owned by that controller. In a dual-controller system, when a
vdisk is created the system automatically assigns the owner to balance the number of vdisks each controller
owns; or, you can select the owner. Typically it does not matter which controller owns a vdisk.
