Data center vendors are making the most out of the fifth annual OpenStack Summit, being held in Portland, Oregon this week. Hewlett-Packard, VMware and Hortonworks are among the many firms that already made headlines at this year’s conference.  Here’s a quick recap of today’s highlights:

HP announced that it has made a significant portion of its converged infrastructure compatible with OpenStack: the 3PAR StorageServ Storage and StorageVirtual line-ups now support the platform across both iSCS and Fibre Channel.  CRN quoted Craig Nunes, the vice president of marketing for HP Storage, as saying that the upgrade fills a “big hole in terms of how Fibre Channel works with OpenStack clouds.”

VMware and Linux distributor Canonical also made news this morning.  The two announced a collaboration that will enable users to deploy VMware technologies, namely vSphere and the Nicira Network Virtualization Platform (NVP), with Canonical’s OpenStack distribution.  The latter will ship with the plugins needed to run the two solutions.

Canonical is not the only company that’s making friends at the Summit. A few hours ago we reported that Hortonworks and Red Hat pledged to support Project Savana, a Hadoop deployment tool for OpenStack created by Mirantis.

Wikibon co-founder and CTO David Floyer discussed the OpenStack community and factors that are contributing to its rapid growth on this morning’s NewsDesk segment, saying:

“The backers are two sets of people: the vendors and the users. Fundamentally it’s an open-source foundation, and this is an unusual business. To some extent people are making a debt by contributing to the code, and then they’re getting back other code from other people extending the framework.  So this is a very interesting business arrangement between the users, who are putting in real work, and the vendors who are offering up pieces of their technology to fit into this overall stack. It is a classic win-win-win situation.”
