Corelink Data Centers: Colocation

Thanks for the interesting and informative post. I look forward to more in the future.

When I look at some of the storage in my lab; with "controllers" that are PCs running Linux, if they had SSDs inside; they'd be "Storage Nodes", in the same Grid with my VM-Host Nodes. I might pair them up with DRBD over a private 10 GigE LAN for redundancy. Or maybe I'd use Glusterfs to replicate across a few of them. Then I'd have a distributed configuration management tool to organize VM access to shared storage; served by that backend. I'd probably also cache the readonly sections of my VM images on the VM-Host Nodes themselves, maybe using even more SSDs installed there too. My Datacenter then has loads of off the shelf servers; arranged in various topologies, connected to a converged fabric, various amounts of direct attached SSD, with nodes running storage, network, or compute software roles. Plus a lot of very clever grid based mgmt software.
