Microsoft Multipath I/O FAQ

For those of you with questions about multipathing, in particular Microsoft’s multipathing solutions, you should check out this article.  It’s the Frequently Asked Questions guide to the Microsoft Multipath I/O (MPIO).  In this article, they describe multipathing as:

Multipathing solutions use redundant physical path components–adapters, cables, and switches–to create logical “paths” between the server and the storage device. In the event that one or more of these components fails, causing the path to fail, multipathing logic uses an alternate path for I/O so that applications can still access their data.

The article has some useful information for both iSCSI and FCP (Fibre Channel Protocol).  One thing worth noting too is that Microsoft does plan to integrate an MPIO-based multipathing solution in Windows Vista (Longhorn).
