Scale Out Disaster Recovery with Nutanix and @VMware SRM

VMware’s Site Recovery Manager (SRM) a disaster recovery management for virtual applications.

VMware host based replication uses VMware snapshots and replicates the snapshots from host to host. VMware snapshots suffer from degraded performance on reads to snapshots with long snapshot hierarchy, and collapsing delta files is extremely slow.

The Nutanix SRA leverages native remote replication, which provides faster and more efficient scale-out replication of Nutanix snapshots.

To use the Nutanix SRA, you must first configure the Nutanix cluster then configure the SRM servers.

Nutanix SRM Architecture


Simple View of the Nutanix SRM Architecture

Both the protected site and the recovery site have a vCenter server that manages protected VMs and an the SRM server. The Nutanix SRA is a set of scripts that must be installed on the SRM servers. The SRA uses the Prism REST API to communicate with Nutanix Operating System(NOS). NOS talks to Cerebros which runs on each host in a scale out fashion. Since recents changes are in flash and all the controller VM’s replicate the data it helps to eliminate bottlenecks in the infrastructure.


A vStore is a separate mount point within a container which has its own NFS namespace. This namespace maps to a Nutanix protection domain. Each vStore is exported as a device through the Nutanix SRA. Since Containers in Nutanix are just an away of applying a policy to a group of VM’s, it’s business as usual. You will have to move your VM’s into the new container associated with protection domain. SRM does have some baggage from the “LUN” world. Nutanix’s native replication does not have this requirement.

Come by the DR booth at VMworld 2013 where and I will fill you in on all of the Techno Wonky Bits.



EUC Tip 88: Adjusting PCoIP offload At Low Bandwidth?

When the network bandwidth for a session goes below 5 Mbps by default, display offloading is cancelled. Once the network bandwidth is above the 6 Mbps by default. The display(s) are eligible for offloading again based on the VM priority and Hardware Accelerator resource availability.

You can adjust the bandwidth for enabling and disabling the card but at lower bandwidth rates features in PCoIP software, such as client image caching will most likely provide more value.

Lots of WAN users? Probably not much need for the card. What about GPU’s in the mix? Check out

Nutanix Dedupe: Past, Present, Powerful

Screen Shot 2013-08-19 at 9.20.58 PMToday Nutanix with the help our brilliant Engineering team released Dedupe for RAM and Flash and a future release will allow dedupe for the capacity tier. This new feature is apart of the 3.5 code release and is available to all Nutanix customers. The release has over 75 features including, a new REST-API, a New UI and a Site Recovery Adapter for VMware’s SRM.

Dedupe will allow for even lower latency’s, lower TCO for Flash and keep Nutanix in the lead on Scale Out Technologies. I want to talk about the importance of this feature in terms of the history of Nutanix, and the impact on the future of the Data Center.

EUC Tip 88: When Should I Use HTML Access with VMware Horizon View?

HTML Access uses more bandwidth and CPU than PCoIP. Some operations may show better performance, but HTML Access is not as optimized as PCoIP. HTML Access is intended for quick and convenient access, not as a replacement for full-time usage. Remember to enable and start the windows firewall before installing the Blast agent on your virtual machine. If you don’t have the ports open you will need TCP 8443 open.
