Logical Disk Capacity
11.1
Arbitrary Logical Disk Capacity
An arbitrary logical disk capacity can be bound by using the management software.
To bind logical disks, enter the capacity in MBs (M=1024^2).
See "Several Settings on PD (Rank and LD build-ups)" or "Execution of Batch Setting
(Rank setting and LD build-up" in "Guide to Setting of NEC Storage Manager
Configuration" for the use of the management software (NEC Storage Manager).
For NEC Storage Manager, the logical disk capacity can be specified with an integer
multiple of the basic capacity, or the least common multiple of (stripe size) × (number of
data disks) and 1024 (400h).
Ex: Capacity secured in RAID-5 (6+P)
Stripe size (100h) × number of data disks (6h) = 600h (768 KB)
The basic capacity is the least common multiple of 400h and 600h.
The capacity must be an integer multiple of C00h (1536 KB).
11.2
Maximum Logical Disk Capacity
The maximum capacity per logical disk is shown in the table below (including the system
capacity of 2 MB).
The capacity can be set by using the management software (NEC Storage Manager).
See "Several Settings on PD (Rank and LD build-ups)" or "Execution of Batch Setting
(Rank setting and LD build-up" in "Guide to Setting of NEC Storage Manager
Configuration" for the use of the management software (NEC Storage Manager).
Enter the value resulting from subtracting the system capacity (2 MB) from the capacity in
the table below as the LD capacity.
