What is new in vSphere 6.0

At an online event at February 2 VMware announced vSphere 6.0. The software will be GA in Q1 2015.

More information on what is new in this post

The post below contains some older information.





This post is part of a serie blogposts on VMworld. For an overview of VMworld announcements see this post. 


At the August 26 keynote of VMworld VMware announced 3 new features of vSphere 6.0. The next version of vSphere is currently in a public beta. Everyone interested can download the bits and try. However the program is under NDA so information on features cannot be publicly shared.

So VMware gave a sneak preview on vSphere 6.0  yesterday. Immediately a couple of blogs published more information on those revealed features.VMware also revealed some information on vSphere 6.0 including vCenter in various breakout sessions. Derek Seaman write some great blogs covering breakout sessions. For example here his blog on a session about vCenter. Session to look for is INF2311

Eric Sloof made an interview with Mike Foley of VMware. Mike explains some new features in his video.

Lets have a look on what is new on vSphere 6.0

ESXi 6.0

  • Fault Tolerance support for 4 vCPU’s. According to a breakout session at VMworld 2014 US Fault Tolerance has been rewritten from the groud up. Info here
  • long distance vMotion. More info here and here Long distance vMotion now support 100ms roundtrip. Used to be 10ms.
  • vMotion across vCenters , vMotion using routed vMotion networks and vMotion across virtual switches
  • Using VMware NSX, network properties will now be vMotioned as well when using long distance vMotion.
  • better vSphere Web Client performance and added features. Still Flex based. Response time is enhanced greatly! The user interface of the web client now is much more similar to the C# client. So less searching for a feature you know to find in c# client.
  • Virtual Volumes. Info here
  • Virtual Datacenters. More info here
  • The vSphere Client (the C# one installed on Windows) will remain available in vSphere 6.0. According to VMware vSphere 6.0 will be the last release having C# client support. Haven’t we heard that before ;-)?

vCenter Server 6.0

Julian Wood also blogged about vCenter Server 6.0. Read his blog here.

  • vCenter 6.0 will support Fault Tolerance. 4 vCPUs, separate storage for primary/secondary VMs and 64GB of RAM
  • Content Library. A way to centrally store VM templates, vApps, ISO images and scripts. The function is similar to the Content Library of vCAC. Content Library’s are replicated over vCenter Server instances. The advantage is a central managed repository preventing for instance severalcopies of  templates of the same guest OS.
  • Certificate management will be greatly improved by a new tool
  • Platform Services Controller (PSC) which  will providings licensing, certificate management and SSO for solutions like vCenter, vCOPs, vCloud Director, vCloud Automation Center
  • PSC will support HA, Fault Tolerance and load balancer for high availability.
  • vCenter Server Appliance (VCSA) 6.0 will support 1000 hosts and 10,000 powered on VMs
  • VCSA still limited to Oracle as the only external database. No ODBC driver in Linux for Microsoft SQL Server.
  • Improved installer. It will ask configuration details, check and then do the install in one go. No seperate installations required.

The features below where not ann0unced during the keyote but where ann0unced by partners. While there is no confirmation these features will be part of vSphere 6.0 it is very likely they will.

  • NVIDIA GRID vGPU. More info and background here. Announced by VMware for 2015. 
  • vSphere APIs for IO Filtering (VAIO)
  • VMFork. A method to  instantly clone running virtual machines.

The VAIO feature was not revealed during the keynote but was mentioned in a session at TechField Day.  vSphere I/O Filters is a VMware supported method for third party vendors to allow interception of storage traffic flow between VM and the ESXi kernel. This allows for features like replication and host based read and write caching. The later allows VMware partners to develop solutions like PernixData does. PernixData developed a kernel module themself for host based read and write caching.


VMware has a course available for developers who like to learn develop vSphere I/O filters. The first two courses are scheduled for mid October and are held in Palo Alto. The program is explained in this short video.

EMC just announced a new product named ‘EMC RecoverPoint for Virtual Machines‘ which uses the VAIO.
