Hi, is there any minimum or recommended set of requirements for the hardware platform to host the new Brahmaputra release? i.e.: number of servers + per server (processing power+memory capacity+storage capacity). Where can this be found?

Advises, experiences?

Thanks in advance.

hey there.

In general, in OPNFV we try to stay away from saying one HW over another. We do "know" (From imperical testing) of certain platforms that work.

Cisco UCS Sunfire X4170 Hp Gen8 and Gen9 Chassis of 460gl/gi.

In terms of memory/cpu and "capacity" of your cloud system, that is really up to the aggregate of what your HW can provide minus the requirements of the components that you are using. Thus, you can use the Openstack minimum requirements + ODL requirements (if you were going to deploy that plugin/scenario) + etc + etc.

One general requirement is that your FUEL node need to have 4-6Cpus, 8GB RAM (mim) = 100-120GB. For the "networking", the hardware is up to you so long as you have a way to satisfy the networking you want to do that the software (overlay) networking level.

Since we have working virtual deploys on controller and computers as smal a 4cp/6GB RAM/250GB and computes with 2cpu/4GB RAM/150GB HD - (anything smaller and it doesnt make sense cause you will never have enough resources to bring up a instance bigger than cirros) - as a guideline to know the minimum x86 64 chip that has V/T and Hyperthreading - after that if the OS supports it / you can get a driver for your nic, you should be able to install this to anything (note: check the HCL for RDO (APEX) and MOS (OPNFV FUEL) if you want to have something they have tested.

Cheers, D
