May 17, 2017VCMP Guest Provisioning Resources
Hi
I am trying to create VCMP guest but need to understand how VCMP guest resource allocation work.
My reference is from https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/vcmp...

May 17, 2017Yes, that's right. The memory isn't added together from all the slots, rather the guest only gets the memory per slot i.e. 6GB in your example. This is so you can lose a slot, or slots, and still function.
This is the key bit:
It is important to understand that the total amount of memory available to a guest is only as much as the host has allocated to each slot. If you instruct the host to allocate a total of two cores per slot for the guest (for example, 6 GB of memory depending on blade model) and you configure the guest to run on four slots, the host does not aggregate the 6 GB of memory on each slot to provide 24 GB of memory for the guest. Instead, the guest still has a total of 6 GB of memory available. This is because blades in a chassis operate as a cluster of independent devices, which ensures that if the number of blades for the guest is reduced for any reason, the remaining blades still have the required memory available to process the guest traffic.
Hope this helps,
