Lukas Lundell describe opportunities for integrating the Nutanix hyper-converged appliance and Nutanix’s Acropolis solution with an OpenStack cloud deployment. Lukas describes how the Nutanix Distributed Storage Fabric and the Acropolis APIs along with the Nutanix OpenStack drivers to build a scalable foundation for any OpenStack cloud deployment.
When I first heard that Nutanix was creating a Volume API to give access to virtual machines via iSCSI I thought it was just arming our customers another option in running MS Exchange. I was sitting in Acropolis training last week and it dawned on me how great this will be for containers and OpenStack. So what is Nutanix Volume API all about?
The volumes API exposes back-end NDFS storage to guest operating system, physical hosts, and containers through iSCSI. iSCSI support allows any operating system to use the storage capabilities of NDFS. In this deployment scenario, the operating system works directly with Nutanix storage bypassing any hypervisor.
Volumes API consists of the following entities:
iSCSI target and group of disk devices.
Storage devices in the volume group (displayed as LUNs for the iSCSI target).
Allowing a specified initiator IQN access to the volume group.
The following image shows an example of a VM running on Nutanix with its operating system hosted on the Nutanix storage, mounting the volumes directly.
Now your OpenStack and containers instances can be blown away and your data will persist! I think this is a big plus for Nutanix and containers running on the Acropolis hypervisor. Future integration with Docker Plugins should now be easier.
OpenStack has been around for a few years now and a lot of people including myself are trying to figure out the larger role in will play in the coming years. Nutanix takes the system approach to OpenStack to deliver enterprise class availability and to address provisioning times by using storage intelligence combined with Flash.
Nutanix NDFS also provides an advanced and unique feature set for OpenStack based
private clouds. Key features include:
• Simplicity – The same great platform that simplified your virtualization
deployment can simplify the compute and storage deployment for key
OpenStack services (Glance, Nova, Horizon, Keystone, Neutron, Cinder,
• Single Scalable Fabric – NDFS provides a single fabric for data storage that
integrates seamlessly with OpenStack services. NDFS-based storage is
easy to provision, manage, and operate at scale.
• Hypervisor Agnostic – Just like OpenStack, Nutanix NDFS was designed from
the ground up to be hypervisor agnostic. Nutanix enables customers to
choose between KVM, Hyper-V, and the VMware ESXi hypervisor for
deployments of OpenStack.
• Enterprise Ready – Nutanix enables a full set of enterprise storage features
including Elastic Deduplication, Compression, In-Memory and Flash-based
Caching, VM-Data Locality, intelligent Information Lifecycle Management (ILM),
Snapshots, Fast Clones, and Live Migration.
