Creating a RAID Device
NSS lets you create a RAID 0 device by striping data across multiple drives
on your system. This RAID configuration occurs at the software level. You
can use this RAID feature for both logical and traditional volumes.
Important information about NSS RAID
Each element in the RAID configuration should come from a different
device. NSS will let you obtain RAID elements from the same device, but
this will severely impede the performance of your file system.
Currently, the NSS RAID supports RAID 0. This means there is no disk
redundancy. If one element in the RAID device malfunctions, the entire
configuration is unusable.
NSS RAID can accommodate a maximum of eight segments (amount of
space used from each device) on a device per RAID 0 logical device.
The stripe size (amount of data the file system places on one device before
moving to the next device) ranges between 4 KB and 256 KB in
increments of 2 KB.
