Overview

  • HP nPartitions

    Cell-based HP servers enable you to configure a single server complex as one large system or as multiple smaller systems by configuring nPartitions. Each nPartition defines a subset of server hardware resources to be used as an independent system environment. An nPartition includes one or more cells assigned to it (with processors and memory) and all I/O chassis connected to those cells. All processors, memory, and I/O in an nPartition are used exclusively by software running in the nPartition. Thus, each nPartition has its own system boot interface, and each nPartition boots and reboots independently. Each nPartition provides both hardware and software isolation, so that hardware or software faults in one nPartition do not affect other nPartitions within the same server complex. You can reconfigure nPartition definitions for a server without physically modifying the server hardware configuration by using the HP software-based nPartition management tools.

  • HP vPartitions

    vPars is a Virtual Partitions product that enables you to run multiple instances of HP-UX simultaneously on one hard partition by dividing that hard partition further into virtual partitions. Each virtual partition is assigned its own subset of hardware, runs a separate instance of HP-UX, and hosts its own set of applications. Because each instance of HP-UX is isolated from all other instances, vPars provides application and Operating System (OS) fault isolation. Each instance of HP-UX can have different patches and a different kernel.
