Is OpenStack appropriate for a closed network like a machine/automobile factory running hundreds of different virtualized applications that need to communicate with each other in near-real-time but not connected to the outside world/internet? More concerned about the responsiveness of the virtual apps. Is there an alternative that would provide a single pane of glass for using and orchestrating the apps? Thanks!

is there any technical reason an OpenStack based VPS provider cannot support IPv6 with full /64 allocations?

There aren't many comprehensive guides out there and the docs aren't really thorough.

How does one go about learning Openstack? I have no idea how the Openstack guys out there do/did it.

My company decided to in-house Openstack instead of using a third party (don't want to pay a third party anymore). My concern is how to effectively monitor Openstack services? I have trouble to find recent information about Openstack monitoring :/

We have looked at vendors to do an initial baseline to get us running on our hardware (a ton of used HPC nodes for hypervisors. Great nodes just not brand new). The prices from our regular folks were unbelievable.

Does anyone know of a service that would do the initial setup of Queens with our own provided hardware and not get wrapped up over certification of hardware? Then they hand us the keys and GTFO unless we have support calls. We could definitely do it ourselves but we don’t have the right FTE allocations to meet the deadline. It’s a lot of poke and experiment to add those extra features (e.g. Manila). Just buying new compute also breaks the budget

Currently we provision bare metal with XCAT and Puppet. Each tenant has its own vlan and subnet. Storage is using GPFS but we are probably going to use a new NFS appliance instead for the new Queens build.

Hi all,

Recently I have the oportunity to collaborate on the design and implementation of a new cloud cluster for a company, and I was thinking on openstack.

The current scenario it's a virtual park with more or less 500 machines running over KVM and admnistrated through virt-manager, it's not very user friendly for diferent ops because there are not configured any kind of ha or failover services between the diferent hosts, they are placed on diferent buildings, in addition we don't have a centralized management of the VMS and there are not configured any orchestration service to deploy new virtual instances, it represent lot of wasted time to implement a new service or vm for example.

Now, the IT department has purchased new hardware, with the plan to reimplement a new cluster to provide all the VMS/Services on the same place with a centralized management (like Ovirt or VSphere). I recently was thinking on a solution based on OpenStack using the KVM hypervisor, but I've a few doubs because the boss was determined that want to work with diferent requirements.

First I share the hardware that they purchased:

(NEW) * x1 Dell PowerVault MD3460 (Storage) * x2 Dell PowerEdge R740 x 2 (Storage Controller) * x4 Dell PowerEdge R440 (Compute) (OLD) * x2 IBM x3650M4 (Compute?)(Without IBM support) * x1 Lenovo RD450(Compute?)

The diferent software requirements to the new architecture was: * IBM GPFS for the filesystem (I dont know if its the most appropiate for this scenario, but it's a requirement due to a boss decision). I think that it can be exported through NFS or provisioned with a driver supported by OpenStack. * XCAT - For deploying the diferent base images through the servers. (Maybe, there are a better option, but like GPFS, it's another company requirement) * SLES- Used as the base system for the infrastructure.

I don't pretend that you design the full cluster but I'm very grateful if you can put your opinions or a posible architecture configuration using this hw and software requirements, and if you consider that there are a better alternative to OpenStack to deploy this kind of scenario, maybe OpenStack was very complex to this solution.

My principal doubt it's the use of the GPFS, I don't how can been presented to the compute nodes as a shared storage on Openstack through the two R740. Maybe NFS? Or dedicated driver?

In the other hand, i don't know if it's better to apply the role of the RD450 as compute node or better as a OpenStack controller, probably the GPFS it will mounted on the two R740 to provide storage and I dont know if it's a good decision put it with xcat services plus the Openstack services.

To close this thread, what do you thing about XCAT? How can I provide through PXE a base image with postcrips or similar to automatize the installation of the diferent cluster or controller nodes? Better Ansible maybe?

This it's my little nightmare for the next months and I appreciate your answers.

Sorry for my English.

Kind regards!
