## 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.
