About Storage Profiles

A storage profile is set of attributes that you apply to a storage pool to allocate storage, instead of having to set each attribute individually. The system has a predefined set of storage profiles. You can choose a profile suitable for the application that is using the storage, or you can create a custom profile.

The Sun StorEdge 6130 array has a default storage profile with RAID-5 storage characteristics that is suitable for many storage applications. The default pool uses the default profile.

Each storage profile has the following settings.

Parameter
Value or Variable Type
Description
Name
Up to 32 characters
Unique identifier for the storage profile.
RAID Level
0, 1, 3, 5
RAID level configured across all disks within a virtual disk.
Segment Size
8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256 KB, 512 KB
Segment size for this profile.
Readahead
Enabled or Disabled
Read-ahead mode of the array. Cache read-ahead enables the controller to copy additional data blocks into cache while the controller reads and copies host requested data blocks from disk into cache.
Disk Type
ANY, FC, or SATA
Disk type.
No. of Disks
5 to 14
The number of disks to be grouped together in a virtual disk. For example, if you create a storage pool with a profile that has the number of disks parameter set to a number, all virtual disks that are part of that storage pool must have the same number of disks. If the number of disks parameter is set to the Variable value you are prompted for the number of disks when storage is added to the pool.
