Scott Lowe writing for Wikibon comments:
The release of the first beta of VMware’s VSAN product has spurred a surge of interest in the hyperconverged infrastructure space. VSAN is VMware’s software solution, which converts server-based storage into a Virtual SAN and is intended to replace traditional networked storage arrays. Hyperconverged infrastructure takes an appliance-based approach to convergence using, in general, commodity x86-based hardware and internal storage rather than traditional storage array architectures. Hyperconverged appliances are purpose-built hardware devices.
Scott really takes VSAN apart in this post and compares it to some of the hottest convergence companies out there, like Scale Computing, SimpliVity, and Nutanix.
