Chapter 1 Introduction

Thank you for installing HP Integrity Virtual Machines (also called Integrity VM). This Release Notes document describes the changes in this version of the Integrity VM product.

The Integrity VM Version 3.5 release introduces new accelerated storage and networking products to improve the overall I/O performance for Integrity VM. These new Accelerated Virtual I/O (AVIO) products provide up to a 60% reduction in service demand and as much as a twofold improvement in throughput over the existing fully-virtualized storage and networking Integrity VM solutions. Performance depends on the application workload, and in general, is better with larger message sizes.

HP Integrity Virtual Machines A.03.50 is supported as a host on HP Integrity servers or nPartitions running HP-UX 11i v2 December 2007 0712 or later. For complete information about the requirements for installing Integrity VM, see the HP Integrity Virtual Machines Installation, Configuration, and Administration manual.
