4.2 IS Features Following is a list of some key features of Integrated Striping: • Striping with 2 to 6 disks on the same channel, allowing greater volume capacity • A single virtual drive is presented to the OS • Support for disks of different types and capacities • Fusion-MPT architecture • Easy-to-use BIOS-based configuration utility (and DOS-based configuration utility for manufacturing use only) • Error notification • Meta data is used to store volume configuration on disks • OS-specific event log • Error display on CIM browser • SAF-TE drive status LED support for IS disks • Support for domain validation • Supports fresh install only - no migration of data on an existing disk 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 4.1, segment 1 is written to disk 1, segment 2 is written to disk 2, segment 3 is written to disk 3, etc. When the system reaches the end of the disk list, it starts writing at the next available segment of disk 1. 4-2 Integrated Striping (IS) Overview Version 1.0 Copyright © 2003 by LSI Logic Corporation.
