During the Day 2 keynote at VMworld (August 26th, 2014), Raghu Raghuram, Executive Vice President, Software-Defined Data Center Division, went ahead and announced the upcoming improvements to vMotion that are bundled in vSphere 6. Here\u2019s a look at the details around this announcement:<\/p>\n
Upcoming new vMotion features:<\/p>\n
vMotion across vCenter Servers (VCs)
\nvMotion across virtual switches: Virtual Standard Switch (VSS), Virtual Distributed Switches (VDSs)
\nvMotion using routed vMotion networks
\nLong-distance vMotion for use cases such as:
\nPermanent migrations (often for Datacenter expansions, acquisitions, consolidations)
\nDisaster avoidance
\nSRM and disaster avoidance testing
\nMulti-site capacity utilization
\nFollow-the-sun scenarios
\nOnboarding onto vSphere-based public clouds (including VMware vCloud Air)<\/p>\n
It’s magic time

\nCrossing Data Centers<\/p>\n
As a vSphere engineer, we\u2019re usually limited to vMotion domains that are limited by a vCenter Server construct (or more specifically, the data center in many cases due to network configurations). vSphere 6 will allow VMs to vMotion across Datacenter and VC boundaries using a new workflow. You\u2019ll also be able to take advantage of a workflow that lets you hop from one network (source) to another network (destination), eliminating the need to have a single vSwitch construct spanning the two locations.<\/p>\n

The configurations targeted are:<\/p>\n
from VSS to VSS
\nfrom VSS to VDS
\nfrom VDS to VDS<\/p>\n
Routed vMotion and Increased RTT Tolerance<\/p>\n
And while you can request a RFQ (request for qualification) to use Layer 3 for vMotion, most of us are limited (or comfortable) with Layer 2 vMotion domains. Essentially, this means one large subnet and VLAN stretched between compute nodes for migrating workloads. An upcoming feature will allow VMs to vMotion using routed vMotion networks without need for special qualification. In addition, another useful feature planned will revolve around the ability to vMotion or clone powered off VMs over NFC networks.<\/p>\n
And finally, the latency requirements for vMotion are being increased by 10x. Enterprise Plus customers today can tolerate vMotion RTTs (round trip times) of 10 ms or less. In the new release, vMotion can withstand 100 ms of RTT.<\/p>\n","protected":false},"excerpt":{"rendered":"
