Recovery Points and Schedules with Near-Sync on Nutanix

Primer post on near-sync

For the GA release near-sync will be only offered with a telescopic schedule (time based retention). When you set the RPO <=15min to >=1 min you will have the option to save your snapshots for X number of weeks or months.

As example if you set the RPO to 1 min and schedule 1 month retention it would look like this:

X= is the RPO
Y = is the schedule

Every X min, create a snapshot retained for 15 mins (These are the Light-Weight Snaps. They appear as normal snap in Prism)
Every hour create a snapshot retained for 6 hours.
Every day, create a snapshot retained for 1 week
One weekly snapshot retained for 4 weeks (If you select a schedule to retain for 7 weeks, Y would be 7 weeks and no monthly snap would occur)
One Monthly snapshot retained for Y months.

Subject to change, as we’re still finalizing sizing and thresholds based on real-world testing but the user will have an option to change these retention values via NCLI.



Delete AFS Forcefully

There can be instances when graceful removal of file server does not work and you may see following errors, this can happen when the file server is not available and has been deleted without following the right process. Sometimes the FSVMs get deleted instead of using the delete workflow in file server section of Prism.

ncli fs delete uuid=________________________
Error: File server with uuid xxxxx-xxxxx-xxxxx is offline and unable to fetch file server VMs.

Use the following command to delete the file server permanently from the Minerva Database. This is run from any CVM.
minerva –fs_uuids _________________ force_fileserver_delete

file server UUID can be obtained from ncli fs ls command.


Powering Off and Starting Up AFS – Native File Services on Nutanix

There really isn’t a need to shut down AFS but moves and maintenance are a part of life. Here are the steps for a clean shutdown….


Shutting Down:
• Power off all guest VMs on the cluster, leaving only FSVM’s and CVM’s powered on.
• From any CVM run: minerva -a stop
• The stop command will stop AFS services and power off the FSVMs for all File Servers
• Once only the CVM’s remain powered on, run Cluster Stop from any CVM.
• Power Off the CVM’s and Hosts

Starting Up:
• Power on Hosts
• CVMs will auto-start once the Host is up
• Once all CVMs are up, run Cluster Start to initiate cluster services
• Verify all services are up with Cluster Status
• From any CVM run: minerva -a start
• The start command will power on the FSVMs for all File Servers and start AFS services
• Power on all remaining guest VMs



Will DR and Backup power AHV sales to 50%?

.Next has come and gone like your favorite holiday. Tons of hustle and bustle with great euphoric feelings followed by hitting a wall and being extremely tired. The Nutanix conference was chalked filled with announcements but the most powering to me were the ones related to DR and Backup. AHV being built with Cloud in mind is surging but adoption has been slowed by 3rd Party backup support. You can have this great automated hypevisor with best in class management but if you can’t back it up easily it will curb adoption.

This number will grow rapidly now with all of the backup and DR

This number will grow rapidly now with all of the backup and DR options

So before .Next 2017 DR and Backup Options for AHV included:
Commvault with support for IntelliSnapp
• Time Stream – Native DR with Time Stream
o 1 node backup with the NX-1155
o Backup/DR to Storage Only Clusters
o Cloud Connect to AWS and Azure
o DR/Backup to a full cluster.
• Any backup software with agents

After .Next 2017 announcements for AHV Backup and DR support include:
HYCU from Comtrade – Rapidly deployed software using turn-key appliances. Great choice if you have some existing hardware that you can use or place onto Nutanix. Point, click, done. Check out more here.
Rubrik – A hardware based appliances that do the heavy lifting for you. Check out more here.
Veeam – Probably best known for making backup easy on ESXi have announced support for AHV later this year. Nutanix added Veeam as a Strategic Technology Partner within the Nutanix Elevate Alliance Partner Program. Going Green!
Druva – Nutanix users can now take full advantage of Druva Phoenix’s unique cloud-first approach, with centralized data management and security. Only ESXi today and agents with AHV but agentless support is coming. More here.
• Backup and DR to full Nutanix Clusters get near-sync to achieve very low RPO. Read more on near-sync here.
Xi Cloud Services, a native cloud extension to the Nutanix Enterprise Cloud Platform that powers more than 6000 end-customers around the globe. This announcement marks another significant step towards the realization of our Enterprise Cloud vision – delivering a true cloud experience for any application, in any deployment model, using an open platform approach. For the first time, Nutanix software will be able to be consumed as a cloud service.

Maybe 50% for AHV is a lofty goal but I can see 40% by next year for new sales as people focus on their business rather than the day to day to headaches. With a very strong backing in backup and DR AHV growth will flourish.
