VMware Inc. has quietly released an update to its NSX virtualized network platform. NSX 6.2 was slipped out the back door without any fanfare four days ago, and the lack of any raving from VMware suggests the company won’t have much to announce in the shape of software-defined networking (SDN) advancements at next week’s VMworld conference.

We say this because from the NSX 6.2 release notes, it doesn’t really look much like an update at all, in fact, it’s more of a bug fix than anything else, according the The Register. The most notable change is that NSX now requires more CPU and memory resources to get up and running – at least 16GB of memory, VMware recommends, while large installations (Vmware defines these as 100 hypervisors, 100 NSX Edges, 1,000 universal distributed firewall rules, and 10,000 non-universal distributed firewall rules) will demand at least 8GB of RAM and a minimum of 8 CPUs.

That’s not to say there aren’t any new features though. There are, including support for Cross vCenter NSX and a consistent firewall policy across multiple vCenters, plus other features that allow NSX 6.2 to run across multiple vCenter instances. There’s also a new Universal Logical Switch (ULS) and Universal Distributed Logical Router (UDLR) that gives administrators the ability for bridging to participate in distributed logical routing, and better IP address discovery so NSX can help to impose security policies.

But it’s also fair to say that much of the work that’s been done on this release has been directed at bug fixes – VMware lists more than fifty fixes and improvements, but also leaves plenty of unresolved issues that have yet to be addressed.

If this quiet and unspectacular release is anything to go by, it’s unlikely we’ll hear much more about NSX at VMworld next week. And, if that’s the case, it could spell disappointment for Wikibon principal analyst Dave Vellante, who recently expressed hopes of learning more about NSX (and VSAN)’s progress at this year’s event, noting how these services are likely to be “the next two revenue drivers for VMware,” and so VMware “has got to start delivering”.

Unfortunately for him, it looks like the only thing VMware will deliver on the NSX front is more of the same.
