Binding Logical Disk - NEC NF2300-SR412E User Manual

Binding Logical Disk

To create a logical disk, 2-step procedure consisting of RANK bind and LD bind is
required.
The RANK bind requires the specification of a RAID level. Select the RAID level
carefully because it has certain influences on system performance and capacity. See
Section 2.5 "RAID Configuration" for details.
The LD bind requires the specification of capacity. The specified capacity defines the
number of logical disks in a single RANK. Select the capacity carefully because the
unused area remaining may affect the performance on the capacity. See Chapter 11
"Logical Disk Capacity" in Appendix A for details.
See "Several Settings on PD (RANK and LD Bindings" in the "Guide to Setting
Configuration of NEC Storage Manager" for how to use the management software (NEC
Storage Manager).
Example: Creation of logical disk 0 of the maximum capacity in 36GB HDD of RAID 5
