I have small doubt. It's related to SVM in solaris 10. I have created raid 0 (striping) using 3 slices of 500 MB size (default interlace value as 32KB)
An interlace is the size, in Kbytes, Mbytes, or blocks, of the logical data segments on a stripe. Depending on the application, different interlace values can increase performance for your configuration. The performance increase comes from having several disk arms doing I/O. When the I/O request is larger than the interlace size, you might get better performance.
