Storage Profile Details Page

This page displays detailed information about the selected profile, including the specific characteristics that the profile assigns to storage.

Field
Indicates
Name
The profile name.
Description
The profile description.
State
The profile state:
  • In Use - A pool exists that uses this profile.
  • Not In Use - No pools exist that use this profile.
You cannot modify or delete profiles that are in use.
Type
The profile type:
  • User - The profile was created by a user.
  • Factory - The profile was provided as part of the system software.
RAID Level
The RAID level of the virtual disk:
  • RAID-0
  • RAID-1
  • RAID-5
Segment Size
The associated segment size in kilobytes: 4 KB, 8 KB, 16 KB, 32 KB, or 64 KB.
This is an array attribute and must be the same for all virtual disks within an array. Once a virtual disk exists on any of the array's trays (there can be only 0, 1, or 2 virtual disks on a tray), then all of the virtual disks on that array's trays must have the same segment size as that virtual disk. Be careful when allocating segment size to a profile, as you cannot have pools whose profiles differ in segment size. You can configure a system with an array that has unused disks in which no virtual disks can be configured if the pools' profiles do not have the same segment size.
Dedicated Hot Spare
Whether the profile has an associated dedicated hot spare: Yes or No. The system has dedicated hot spares (controlled by this attribute) and array hot spares (controlled as an editable attribute on the Array Details page).
  • Dedicated hot spare - There is a one-to-one correspondence between a dedicated hot spare and a virtual disk (that is, the hot spare is dedicated to a specific virtual disk). This profile attribute controls whether a dedicated hot spare disk is assigned to the virtual disk when a virtual disk is created in a pool with this profile.
  • Array hot spare - This is a disk in an array that can act as a hot spare for any disk in the array.
The number of drives and dedicated hot spare attributes taken together define how many disks are consumed for each virtual disk in a pool.
Read-Ahead Enabled
Whether the read-ahead attribute is enabled or disabled. This array attribute must be the same for all virtual disks within an array. Once a virtual disk exists on any of an array's trays (you can have only 0, 1, or 2 virtual disks on a tray), all of the virtual disks on that array's trays must have a Read-Ahead Enabled setting that matches that virtual disk's Read-Ahead Enabled setting. You must plan the use of the Read-Ahead Enabled setting carefully, because you cannot have pools whose profiles have different Read-Ahead Enabled settings on the same array. You can configure a system with unused disks in which no virtual disks can be configured if the pools' profiles do not match the Read-Ahead Enabled setting.
# Drives
The number of drives associated with this profile. This is the number of disk drives that are used to construct the virtual disk in a pool using this profile.
The number of drives can be 2 to 14, or variable. If it is set to variable, you must specify the number when you create virtual disks (that is, when you add storage to the pool).
Array Type
The type of array.
The options below match only a specific array configuration (2x2, 2x4, and 2x6). If a profile has one of these options but the specific array is unavailable, the profile cannot be used.
Exact Match: IOPs (2x4 array)
Exact Match: Bandwidth (2x2 array)
Exact Match: Capacity (2x6 array)
The following options and rules attempt to match the best available array based on the environment (IOPs, bandwidth, capacity):
Best Available Match: IOPs - 2x4 > 2x2 > 2x6
Best Available Match: Bandwidth- 2x2 > 2x4 > 2x6
Best Available Match: Capacity - 2x6 > 2x4 > 2x2
Virtualization Strategy
The type of virtualization that is associated with this profile, either Striped or Concatenated.
Stripe Size
The stripe size associated with this profile, if it is striped: 128 KB, 256 KB, 1 MB, 2 MB, 4 MB, 8 MB, or 16 MB.
