This vBrownBag presentation provides an overview of the integrations available for running vSphere in an OpenStack environment.

Transcript of VMware vSphere in an OpenStack Environment

  • 1.VMware vSphere in an OpenStack Environment A quick, informal, and unofcial look at VMware vSphere in an OpenStack environment Scott Lowe, VCDX 39 vExpert, Author, Blogger, Geek http://blog.scottlowe.org / Twitter: @scott_lowe

2. Agenda OpenStack Compute (Nova) integration OpenStack Block Storage (Cinder) integration VMware OpenStack Virtual Appliance (VOVA) Q&A 3. OpenStack Compute (Nova) Integration As of Grizzly, two drivers are available for integrating vSphere into OpenStack: ESX driver (compute_driver=vmwareapi.VMwareESXDriver) VC driver (compute_driver=vmwareapi.VMwareVCDriver) ESX driver is unable to take advantage of advanced capabilities (no vMotion, no DRS, no HA) VC driver enables the use of vMotion, DRS, HA within OpenStack deployments 4. OpenStack Compute (Nova) Integration: ESX Driver ESX driver uses one nova-compute instance per ESXi host This nova-compute instance typically runs as a VM on the ESXi host it is managing Not really being developed/enhanced over time (effort is going into VC Driver) 5. OpenStack Compute (Nova) Integration: VC Driver The VC Driver was rst introduced with Grizzly Abstracts an entire cluster as a single nova-compute instance Details of ESXi clusters are hidden from OpenStack This enables HA, DRS, vMotion, etc. Original Grizzly version was single-cluster driver To scale to multiple clusters, youd need multiple nova- compute instances These nova-compute instances could run as separate VMs or as processes on the same VM 6. OpenStack Compute (Nova) Integration: VC Driver VC Driver in Havana will introduce multi-cluster operation Allows for a single nova-compute instance to represent multiple clusters Uses multiple cluster_name parameters in nova.conf, one for each cluster Still have the option of using multiple nova-compute instances to represent multiple clusters 7. OpenStack Compute (Nova) Integration: VC Driver 8. OpenStack Compute (Nova) Integration: VC Driver 9. OpenStack Block Storage (Cinder) Integration New to Havana, not present in Grizzly Allows for persistent block storage volumes to be stored as VMDKs on VMFS datastores Supports create, attach, detach, destroy operations 10. OpenStack Block Storage (Cinder) Integration 11. VMware OpenStack Virtual Appliance (VOVA) A VMware Fling-type tool designed to help VMware administrators kick the tires with vSphere and OpenStack An all-in-one deployment of OpenStack packaged up as a vApp Leverages vApp properties to automatically congure OpenStack and VCDriver Get it here: https://communities.vmware.com/docs/DOC-24626 Provide feedback!
