We are using multiple storage backend / topology on our side ranging from ScaleIO to CEPH passing by local compute host storage (were we need cold storage) and VNX, I have to said that CEPH is our best bet. Since we use it we clearly reduced our outages, allowed our user advanced features such as live-migration, boot from volumes and on top of that a better and more reliable performance.
Yet we still need to get live and cold migration the same features set as our users/customers are really expecting us to provide a seamless experience between options. I can’t really speak out about real numbers but I’m within the video game industry if that help to drive support and traction/interest. Thanks for the survey btw. Kind regards, Gaël.
