## Managing Profiles

Clicking the Array Management Profile tab displays the Profile Management page. You can choose a pre-configured profile or create a new one. Filter the profiles to display with the following information:

- Name - The profile name
- Raid - RAID level 0, 1, or 5 configured across all disks within a virtual disk

Segment size- A segment size of 4 Kbytes, 8 Kbytes, 16 Kbytes, 32 Kbytes, or 64 Kbytes. In a RAID-5 configuration, the segment size is the size of the data striped across volumes.

- Readahead - The read-ahead cache.status (on/off)
- Array Type - Determines the specific array type to use:

1) Exact Match - IOPS (1x2, 2x4 array)

2) Exact Match - Bandwidth (1x1, 2x2 array)

3) Exact Match - Capacity (1x3, 2x6 array)

4) Best Available Match - IOPS

5) Best Available Match - Bandwidth

6) Best Available Match - Capacity

Types 1 to 3 match only one array configuration (1x1, 1x2, 1x3, 2x2, 2x4, 2x6). If a profile has one of these three parameter settings and the specific array is not available, then the profile cannot be applied.

Types 4 to 6 attempt to match the best available array based on the environment (IOPs, Bandwidth, Capacity). For example, Best Available Match - Capacity will search for 2x6s, then 2x4s, then 2x2s. The following rules apply to the three Best Available Match settings for the listed models:

- (SE6120: MR-1) IOPS: 1x2 - 1x1 - 1x3
- (SE6120: MR-1) Bandwidth: 1x1 - x2- 1x3
- (SE6120: MR-1) Capacity: 1x3 - 1x2 - 1x1
- (SE6120: MR-2, SE6320) IOPS: 2x4 - 2x2 - 2x6
- (SE6120: MR-2, SE6320) Bandwidth: 2x2 - 2x4 - 2x6
- (SE6120: MR-2, SE6320) Capacity: 2x6 - 2x4 - 2x2

Note: that for the last three choices, the array or system determines the best available match.
