5.2.4.3 IS Description
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 Kbyte 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 Figure, 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
Below Figure 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.
