A group of us just published an analysis of VMworld (Breaking Down VMworld), and I thought I’d take this opportunity to add some additional color to the analysis. The report is an excellent synthesis of our analysis, the work of a talented team of collaborators with my two cents thrown in as well, but I wanted to emphasize a few additional impressions, primarily around storage, converged infrastructure, and the overall tone of the show.
First, storage. If they ever need a new name for the show, they might consider “StorageWorld” – it seemed to me that just about every other booth on the show floor was about storage. Cloud storage, flash storage, hybrid storage, cheap storage, smart storage, object storage … you get the picture.[i] Reading about the hyper-growth of storage and the criticality of storage management to the overall operation of a virtualized environment does not drive the concept home in quite the same way as seeing 1000s of show attendees thronging the booths of the storage vendors, large and small, for days on end. Another leading indicator, IMHO, was the “edge of the show” booths, the cheaper booths on the edge of the floor, where smaller startups congregate, which was also well populated with new and small storage vendors – there is certainly no shortage of ambition and vision in the storage technology pipeline for the next few years.
Last year at VMworld I noted Xsigo Systems, a small privately held company at VMworld showing their I/O Director technology, which delivereda subset of HP Virtual Connect or Cisco UCS I/O virtualization capability in a fashion that could be consumed by legacy rack-mount servers from any vendor. I/O Director connects to the server with one or more 10 G Ethernet links, and then splits traffic out into enterprise Ethernet and FC networks. On the server side, the applications, including VMware, see multiple virtual NICs and HBAs courtesy of Xsigo’s proprietary virtual NIC driver.
Controlled via Xsigo’s management console, the server MAC and WWNs can be programmed, and the servers can now connect to multiple external networks with fewer cables and substantially lower costs for NIC and HBA hardware. Virtualized I/O is one of the major transformative developments in emerging data center architecture, and will remain a theme in Forrester’s data center research coverage.
This year at VMworld, Xsigo announced a major expansion of their capabilities – Xsigo Server Fabric, which takes the previous rack-scale single-Xsigo switch domains and links them into a data-center-scale fabric. Combined with improvements in the software and UI, Xsigo now claims to offer one-click connection of any server resource to any network or storage resource within the domain of Xsigo’s fabric. Most significantly, Xsigo’s interface is optimized to allow connection of VMs to storage and network resources, and to allow the creation of private VM-VM links.
