摘要：
The Distributed Virtual I/O Tool replaces dedicated VIO server LPARs by distributing the virtual I/O functions across several application LPARs connected by a high-speed communication channel. The physical I/O devices are distributed across available LPARs. The Distributed Virtual I/O Tool assigns each I/O request to an appropriate I/O device. The Distributed Virtual I/O Tool monitors each I/O request and reassigns I/O devices when performance drops on a specific device or when a device is no longer available.
