Advanced CLI configuration page of the ExpressNAV interface. Zoning supports security by granting or denying access between initiators and devices as defined by an administrator.
A zone is a collection of devices which can access each other. The devices in a zone usually include one or more initiators, one or more devices, and one or more paths between the initiators and the devices.
Interleave
The interleave size sets the amount of data to be written to each drive in a RAID group. This is a tunable parameter which takes a single stream of data and breaks it up to use multiple disks per I/O interval.
•The default sector interleave in RAID Level 10 is 128 blocks (64k).
•The default sector interleave in RAID Level 5 is 256 blocks (128k).
The CLI command RAIDInterleave allows you to change the size of the sector interleave between RAID groups. The value will depend upon the normal expected file transfer size. If the normal file transfer size is large, the interleave value should be large, and vice versa.
The value entered for the RAIDInterleave command refers to blocks of data: one block is equivalent to 512 bytes of data.
Valid entries are 16, 32, 64, 128, 256 and SPAN. SPAN, not available in RAID Level 5, indicates that interleave size between the drives in the group will be the minimum drive size of all members in the group.
