25 Managing Data Allocation
The Layout Grid Manager allows you to view layout grids showing patterns of virtual volume, CPG,
logical disk, and physical disk usage. These grids can be used to monitor resource allocation.
NOTE: Logical disk information only appears if you have set your preferences in the HP 3PAR
Management Console to display logical disk information. See “Setting Global Preferences”
(page 511) .
The following figure describes the structure of each layout grid:
Table 1 Layout Grid
Description Item
List of all physical disks 1
10 chunklet marker 2
30 chunklet marker 3
1 cell = 1 chunklet = 256 MB 4
All types of chunklet grid screens share the same basic features:
•
The far left column lists all physical disks in the storage server using the format:
::
◦ – Can be 0 (left side of the drive chassis) or 1 (right side of the drive chassis).
◦
– Can be 0, 1, 2, 3, or 4.
◦ – Can be 0, 1, 2, 3, or 4, where 0 is the position closest to the backplane.
•
Each row represents the storage space of the disk indicated in the left column, with each cell
in the grid representing one chunklet, or 256 MB.
•
Markers indicating the quantity of chunklets in multiples of 10 appear along the top of the
grid.
