Hardware and software requirements

The following information provides a consolidated view of the hardware and software requirements for your IBM® Power® Virtualization Center environment.

Hosts

Table 1. Hardware and operating system requirements for PowerVC hosts.
Host type Supported hardware Supported operating systems
PowerVC management server

x86_64

To determine the supported IBM Power hardware for RHEL 7 and later, see the appropriate page:

Red Hat Enterprise Linux (RHEL), version 7.n, where n is 1 or higher for IBM Power for ppc64 and ppc64le

Red Hat Enterprise Linux (RHEL) Server, version 7.n, where n is 1 or higher for x86_64

Managed hosts
IBM POWER6 or later processor classes.
  • Includes all form factors, such as chassis, rack, blade, and Power Flex.
  • All other PowerVC requirements apply, including storage, networking, guests, and so on.
  • Managed hosts should have a minimum of 4 cores and 8 GB of memory.
For details about the supported guest operating system levels for deployed virtual machines, see Supported activation methods.
Note: The version of RSCT installed on AIX® and Linux deployed guest operating systems should have the latest fix applied.
The following information describes the minimum and recommended resources required for PowerVC virtual machines. In the table, the meaning of the "Processor capacity" column depends on the type of host that is being used as the PowerVC management server.
  • If the PowerVC management server is PowerVM®, "Processor capacity" refers to either the number of processor units of entitled capacity or the number of dedicated processors.
  • If the PowerVC management server is PowerKVM or x86, "Processor capacity" refers to the number of physical cores.
Table 2. Minimum resource requirements for a PowerVC virtual machine
  Minimum Recommended
Number of virtual machines   Up to 400 401-1000 1001-2000 2001-3000 3001-5000
Processor capacity 1 2 4 8 8 12
Virtual CPUs 2 2 4 8 8 12
Memory (GB) 10 10 12 20 28 44
Swap space (GB) 10 10 12 20 28 44
Disk space (GB) 40 40 60 80 100 140
The installer has the following space requirements:
  • /tmp: 250 MB
  • /usr: 250 MB
  • /opt: 2.5 GB
  • /home: 3 GB (minimum). It is recommended that 20% of the space is assigned to /home. Examples: For 400 virtual machines, 8 GB are recommended. For 1000 virtual machines, 20 GB are recommended. For 2000 virtual machines, 30 GB are recommended.
  • The remaining space is used for /var and swap space.

Hardware Management Console

It is recommended that the HMC has all current updates installed. To see the latest updates, go to the Hardware Management Console page in Fix Central.

Table 4. HMC requirements
Item Requirement
Software level
  • 8.3.0
  • 8.4.0
Hardware level Requirements
  • Up to 300 virtual machines: CR5 with 4 GB memory
  • More than 300 virtual machines: CR6, CR7, or CR8 with 8 GB memory

Recommendations

  • Up to 300 virtual machines: CR6, CR7, or CR8 with 8 GB memory
  • More than 300 virtual machines: CR6, CR7, or CR8 with 16GB memory

Virtualization platform

Note: PowerVC does not install or configure third-party software on the Virtual I/O Server.  Any third-party software that you want to use for Virtual I/O Server resources must be installed and configured on the Virtual I/O Server before managing it with PowerVC.

It is recommended that the Virtual I/O Server has all current updates installed. To see the latest updates, review the available Virtual I/O Server updates in IBM Fix Central.

Table 5. Supported virtualization platforms.
Platform Requirement
Virtual I/O Server (VIOS) for POWER8 or earlier Version 2.2.3.x, where x is 52 or later. Version 2.2.4.x, where x is 10 or later.

The version of RSCT installed on the Virtual I/O Server should have the latest fix applied.

Network
