starting up VCL (probably from scratch)
Dear VCL users,
We have been exploring a lot of information related to VCL since the IBM
cloud conference that took place about a year ago...
The objectives are clear, and the NCSU deployment explains a lot about how
VCL actually works...yet one topic seems to remains "obscure".
Please excuse my question if it seems to be naive, but what if somebody ask
you folks specifically about "the minimum" requirements (hardware and
software) for a private cloud with VCL to run??. What would you say?
Please remember that occasionally we need to explain such an abstract
concept to non-IT people and when the specifics come to mind, this question
seems to be natural.
I tried in a previous e-mail to find this out asking what it takes to
prepare a VCL demonstration, but I still feel unable to state what to
prepare…
Any comments on the matter?? (greatly appreciated)

Thank you Josh ...the information really clarifies the matter.
By the way, I think it would be a great idea to post this information on
the VCL module website

Oscar,
If you just want do demonstrate how VCL works, that could be done with a
desktop class system with 60 GB of drive space and 4 GB of RAM. That would
give you enough to have a Linux and a Windows image and 2 VMs that could be
deployed.
If you want a system to be able to run a small pilot for a single class of
around 30 students, you could target a system that would handle 10 concurrent
users. That would mean you would need to be able to run 11 VMs concurrently -
1 for the VCL system and 10 for users. You could do this on a single server.
The software being made available to the users and the type and speed of the
drives in the system greatly affects things, but shooting for light to medium
load software and slower drives, you could probably get by with 48 GB of RAM
and 5 drives in a RAID-5 configuration with 750 GB of usable space. You'd
probably be okay with 2 quad core processors.
I'm not sure how to answer the "minimum software" part. It's really up to you
as to what software you want to provide to your users. The VCL system runs on
Linux - we typically recommend using CentOS. You can use KVM as your
hypervisor or ESXi in the free license mode. If you just want to provide
Linux images to your users, then there would be no software licensing costs.
If you want to provide Windows images, you'll need to talk to your Microsoft
sales rep. Things seem to vary from one rep to another as to what things need
to be licensed.
