Byte Information Table; Byte Information - HP StorageWorks P9000 - Disk Arrays Configuration Manual

Notes for disk parameters
1. The value of pc is calculated as follows:
pc = nc * nt * ns
The nc of OPEN-x CVS corresponds to the capacity specified by SVP or remote console.
The CVS size of OPEN-x is specified by capacity (megabyte), not by number of cylinders.
The number of cylinders of an OPEN-x CVS volume can be obtained by the following calculation
( ... means round up to integer).
The number of cylinders = (specified capacity in megabytes from SVP or remote console) x
1,024 / 720 .
Example
When 37 MB is specified for an OPEN-3 CVS volume from SVP,
the number of cylinders of the OPEN-3 CVS can be
calculated as follows:
37 x 1,024 / 720 = 52.62
52.62
The OPEN-3 CVS volume has 53 cylinders.
2. The value of pa must be equal to or more than 131,072.
3. The number of cylinders of a Logical Unit Size Expansion (LUSE) composed of OPEN-x CVS
volumes corresponds to the capacity specified by the SVP or the remote console. CVS size of
OPEN-x is specified by the capacity (megabytes), not by the number of cylinders. The number
of cylinders of the OPEN-x CVS volume can be obtained by the following calculation ( ...
means round up to integer):
The number of cylinders = (specified capacity in megabytes from SVP or remote console) x
1,024 / 720 x n
where n is the number of concatenated volumes for LUSE.
Example
When 37 MB is specified for the OPEN-3 CVS volume and the
four volumes are concatenated, the number of cylinders of
the OPEN-3 CVS can be calculated as follows:
37 x 1,024 / 720
The LUSE for the OPEN-3 CVS volume has 212 cylinders.

Byte information table

Values in this table assume that large files are stored in large volumes, and the maximum number of
files stored in each device type is approximately the same for each device type.
