SES status LED support for drives used in IS volumes

The IS feature writes data across multiple disks instead of onto one disk. This is 
accomplished by partitioning each disk’s storage space into 64-KB stripes. These 
stripes are interleaved round-robin, so that the combined storage space is composed 
alternately of stripes from each disk.

For example, as shown in 

, segment 1 is written to disk 1, segment 2 is written 

to disk 2, segment 3 is written to disk 3, and so on. When the system reaches the end of 
the disk list, it continues writing data at the next available segment of disk 1.

 shows a logical view and a physical view of Integrated Striping configuration.

The primary advantage of IS is speed, because it transfers data to or from multiple disks 
at once. However, there is no data redundancy; therefore, if one disk fails, that data is 
lost.
