Cisco Metacloud September 2017 Update (Metacloud version 4.6)

This 4.6 release of Cisco Metacloud contains the full availability of the Nimble storage driver, support for Vector Packet Processing (VPP), support for Red Hat Enterprise Linux (RHEL) 7.4, and bug fixes for the Dashboard, Orchestration templates, live migration, and storage.

Feature Updates

The following feature updates and improvements have been included in the 4.6 release:

  • The Nimble storage driver is now fully supported in the 4.6 release. See Nimble Storage Driver.
  • Vector Packet Processing (VPP) is now enabled in the 4.6 release. VPP is a very fast software switch for highly network-intensive applications. VPP supports high-performance VM dataplane traffic. Metacloud integrates VPP with a VPP-agent to enable Layer 2 high performance VM throughput. Typically, VPP targets NFVi use cases or specific VNFs. VPP replaces LinuxBridge technology when you require high VM traffic throughput. If you are interested in using VPP in your Metacloud environment, contact your Cisco account manager.

    For more information on VPP, see The Fast Data Project.

The following bug fixes have been applied in the 4.6 release:

  • Storage volumes are now correctly removed and are no longer listed as “in use” after the attached server is deleted.
  • Live migrations now complete correctly.
  • Compute nodes no longer experience packet loss.
  • Orchestration templates now correctly launch instances.
