Arbitrary Logical Disk Capacity; Maximum Logical Disk Capacity - NEC S1300 User Manual

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).
For management software, 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)

Maximum Logical Disk Capacity

The maximum capacity per logical disk is shown in the table below (including the
system capacity of 2 MB).
Enter the value resulting from subtracting the system capacity (2 MB) from the capacity
in Table 1-6 as the LD capacity.

1-14 Disk Array Unit Overview
This Manual:http://www.manuallib.com/nec/s1300ug-disk-array-unit-user-guide.html
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).
