Six Virtualization Technologies in HP-UX"

Article Title: HP-UX six virtualization technology "partition ". Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

From the perspective of HP-UNIX, virtualization technology and its related products can be divided into six basic categories based on the number of cores, servers and the number of operating system instances involved. The following shows the categories and their relationships with the processing core, servers, and operating system instances.

This article introduces the fifth type: partitioning (multiple operating systems, one multi-processor server)

If multiple cores exist, virtualization is more likely. This virtualization technology is called partitioning. HP Systems have multiple types of partitions, but they are divided into two main categories: hardware Partition and software partition.

1) hardware partitioning

Hardware partitioning is implemented at the unit board level through HP's nPartition technology. Hardware partitioning is implemented on servers that support multiple unit boards (Integrity and PA-RISC) to isolate (logically and electrically) Multiple Operating System instances. That is to say, the Unit board, core, I/O Card, and memory allocated to a hardware Partition can only be used by the operating system running in the partition. If an operating system, software, or even hardware problem occurs in a partition, the operating system and software running in other partitions are not affected.
