List,
Very recently I came across a discussion with a banking corporation who are heavy users of VMware in all their Data Centre operations ..
They asked me a lot of questions in comparison with openstack vs other proprietary vendors (such as VMware. ).
As I am promoting OpenStack I need to clarify these questions raised by the organization.
I request your inputs for these queries .
1. Does OpenStack support Hyper Converged Infrastructure ? Or any HCI vendors already with OpenStack solutions? Please share the URL/link of case studies of OpenStack HCI. Any documentation/Reference to install openstack as HCI solution with supported H/W OEM details . I can try out ...
OpenStack does, as you are free to deploy the way you want. However, from my point of view, this is a bad idea: it's hard to get guaranteed I/O if you mix Ceph OSD and compute roles.
4. Does OpenStack new versions support VDI(Virtual Desktop Infrastructure) solutions out of the box.? pls give a reference link / url for the same.
Yes. 2 ways to do it: give a full PCI device to your instance, or use virtualized GPU. Nova can do both.
8. Tools to maintain multiple OpenStack Cluster
Yes.
any concept of Supervisory cluster available
I don't know what that is (and many of the VMWare concept you mentioned but I didn't quote). I hope the above helps. Cheers, Thomas Goirand (zigo)
