Whats new in vSphere 5.5

Posted by on August 26, 2013 in vSphere | 0 comments

With all the crazy media traffic going on this week with VMworld this post will probably get little attention. But I wanted to put something together that summarizes the updates in vSphere 5.5

I’m not going into in depth coverage of each of these you can find that at the link to the VMware PDF at the end of the post. I have offered my commentary on the items that I think are the most interesting.

vSphere ESXi Hypervisor Enhancements

  • Hot-Pluggable SSD PCI Express (PCIe) Devices
  • Support for Reliable Memory Technology
  • Enhancements for CPU C-States

Virtual Machine Enhancements

  • Virtual Machine Compatibility with VMware ESXi™ 5.5
  • Expanded vGPU Support (Now support GPUs from Intel and AMD, good to see the hardware list expand this will only help in adoption)
  • Graphic Acceleration for Linux Guests

VMware vCenter Server Enhancements

  • VMware® vCenter™ Single Sign-On
  • VMware vSphere Web Client
  • VMware vCenter Server Appliance™
  • vSphere App HA (I like the idea of this, this initial offering is very limited in apps that are supported. Also the required setup seems to be a lot for what you are able to accomplish)
  • vSphere HA and VMware vSphere Distributed Resource Scheduler™ (vSphere DRS) (Good to see these features become more integrated and work together better.)
  • Virtual Machine–Virtual Machine Affinity Rules Enhancements
  • vSphere Big Data Extensions

vSphere Storage Enhancements

  • Support for 62TB VMDK (While not a huge demand for this it’s been a long time coming.)
  • MSCS Updates
  • vSphere 5.1 Feature Updates
  • 16GB E2E support
  • PDL AutoRemove
  • vSphere Replication Interoperability
  • vSphere Replication Multi-Point-in-Time Snapshot Retention (This was good to see additional capabilities added to the vSphere replication. Should be welcomed by customers adopting this method.)
  • vSphere Flash Read Cache (Nice to see this but I wonder how much value this offers given what some 3rd party vendors have recently brought to market. Might end up being something that you turn on for some added benefit and you use a 3rd party for the very intensive needs.)

vSphere Networking Enhancements

  • Link Aggregation Control Protocol Enhancements
  • Traffic Filtering
  • Quality of Service Tagging
  • SR-IOV Enhancements
  • Enhanced Host-Level Packet Capture
  • 40GB NIC support


You can find the full list and details about all the new features and updates in the vSphere 5.5 release PDF.
