Multitenancy and vCMP virtualization in F5 Big-IP

Multi-tenant environment (BIG-IP hardware chassis) and Virtualization (vCMP functionality) are 2 of the most debatable models, with each setup having its own features and benefits depending on volume of traffic we have in our environment.  Let’s have a brief comparison of their features before actually focusing on vCMP d\feature on BIG-IP Viprion. Below is the table –

Below illustration shows the problem which we have in Multi-Tenant Environment: –


Now, let’s start focusing on the real topic – vCMP. vCMP feature allows BIG-IP to virtualize its hardware to provide multiple instances . vCMP stands for Virtualized Clustered Multiprocessing. vCMP is a hypervisor in F5 which allows you to divide one physical high powerful F5 device into multiple independent virtual F5 devices.

Below are the key takeaways of vCMP –

Some key notes on vCMP

  • vCMP host is the hypervisor which allows you to create and configure BIG IP Instances.
  • This Instances are known as vCMP guests.
  • For every guest, vCMP host allocates CPU and memory to it.
  • A guest consists of a TMOS instance, plus one or more BIG-IP modules.
  • Each guest has its own share of hardware resources that the vCMP host allocates to the guest, as well as its own management IP addresses, self IP addresses, virtual servers, and so on.
  • Each guest can use TMOS features such as route domains and administrative partitions to create its own multi-tenant configuration.
  • Each guest requires its own guest administrator to provision, configure, and manage BIG-IP modules within the guest.
  • Depending on the hardware model, a vCMP system can support up to approximately six guests.
