VMworld attendees get to the Docker booth to save money & time like Visa.

    The Docker booth is right beside the Nutanix booth at VMworld this year so I have seen lots of people there but not 23,000 but there should be. Docker had been apart of all the announcements if you realized it our not. Lots of talk about Google with Kubernetes. Kubernetes still requires Docker as the container engine so whether it’s Swarm or Kubernetes you’re going to be using Docker. If you want Enterprise support Docker is both you want to be visiting and learning what they can do to develop better end to end software while saving you money.

    With Docker EE has been in production at Visa for over 6 months and is seeing improvements in a number of ways:

    Provisioning time: Visa can now provision in seconds rather than days even while more application teams join the effort. They can also deliver just-in-time infrastructure across multiple datacenters around the world with a standardized format that works across their diverse set of applications.
    Patching & maintenance: With Docker, Visa can simply redeploy an application with a new image. This also allows Visa to respond quickly to new threats as they can deploy patches across their entire environment at one time.
    Tech Refresh: Once applications are containerized with Docker, developers do not have to worry about the underlying infrastructure; the infrastructure is invisible.
    Multi-tenancy: Docker containers provides both space and time division multiplexing by allowing Visa to provision and deprovision microservices quickly as needed. This allows them to strategically place new services into the available infrastructure which has allowed the team to support 10x the scale they could previously.

    Visa moved a VM-based environment to containers running on bare metal and saved the time to provision and decommissioned its first containerized app by 50%.By saving time and money on the existing infrastructure and applications, organizations can reinvest the savings — both the time and money — in transforming the business.

    BTW Nutanix can do bare-metal or run AHV to provide great experience for containers with our own Docker Volume plugin.


    #Nutanix #AFS – Cannot access folders/files created with a dot “.”

    You may experience issues with third party application when accessing folders/files with a dot “.” prefix in the name such as “.profile” or “.build”.

    One of the error messages may look like the one below.

    Error mesessage
    The “.profile” has different permissions.

    This is pertaining folders like “.profile” or “.build”. If can create the folders and see them, but when trying to access them with programs, it throws access errors. The “dot files” have different permissions.

    There is a configuration option called “hide dot files” in AFS. This “hide dot files” configuration option is enabled by default in AFS.

    You can run the following command on one of the FSVMs to turn off the “hide dot files” option globally.

    scli smbcli global "hide dot files" No

    Example of the command run successfully below.
    nutanix@NTNX-x-x-x-x-A-FSVM:~$ scli smbcli global "hide dot files" no
    No existing config 'hide dot files' in smb.conf. Creating a new entry now..!
    smb.conf update is successful


    Nutanix Docker volume plugin updated

    Last week Nutanix published an update to the Nutanix docker volume plugin with support ubuntu, docker datacenter compatibility and improved logging among other improvements.

    Supported scopes for the plugin are global and local. Any other value in Scope will be ignored, and local is used. Scope allows cluster managers to handle the volume in different ways. For instance, a scope of global, signals to the cluster manager that it only needs to create the volume once instead of on each Docker host.


    Move Your DBs From Cloud or 3-Tier Clunker to Nutanix with Xtract

    Xtract for DBs enables you to migrate your Microsoft SQL Server instances from non-Nutanix infrastructures (source) to Nutanix Cloud Platform (target) with a 1-click operation. You can migrate both virtual and physical SQL Servers to Nutanix. Xtract captures the state of your source SQL Server environments, applies any recommended changes, recreates the state on Nutanix, and then migrates the underlying data.

    Xtract is a virtual appliance that runs as a web application. It migrates your source SQL Server instances to Nutanix in the following four phases:

    Scanning. Scans and discovers your existing SQL Server environments through application-level inspection.
    Design. Creates an automated best practice design for the target SQL Servers.
    Deployment. Automates the full-stack deployment of the target SQL Servers with best practices.
    Migration. Migrates the underlying SQL Server databases and security settings from your source SQL Servers to the target SQL Servers.
    Note: Xtract supports SQL Server 2008 R2 through SQL Server 2016 running on Windows 2008 through Windows 2012 R2.

    Xtract first scans your source SQL Server instances, so that it can generate a best-practice design template for your target SQL Server environment. To scan the source SQL Server instances, Xtract requires the access credentials of the source SQL Server instances to connect to the listening ports.

    You can group one or more SQL Server instances for migration. Xtract performs migrations at the instance level, which means that all databases registered to a SQL Server instance are migrated and managed as part of a single migration plan. Xtract allows you to create multiple migration plans to assist with a phased migration of different SQL Server instances over time.


    Once the full restore is complete and transaction logs are in the process of getting replayed, you can perform the following actions on your SQL Server instances:

    In the Migration Plans screen, you can perform one of the following:

    Start Cutover
    The cutover operation quiesces the source SQL Server databases by placing them in the single user mode, takes a final backup, restores the backup to the target server, and then brings all the databases in the target server online and ready for use. This action completes all migration activities for a migration plan.


    The test operation takes a point-in-time copy of the databases in the source instance and brings them online for testing in the target SQL Server instance. This action does not provide a rollback. Once a Test action has been initiated, you can perform tests on the copy. However, if you want to perform a cutover after the Test operation, you should begin again from the scanning phase.

    Come to the Nutanix Booth at VMworld in Vegas to see it in action. One-click yourself out of your AWS bill.


    Top 10 Reasons Why Nutanix Is The Best Platform For Horizon View

    1) Turn key-solution for desktops and RDSH with vGPU.
    2) All roads lead to a non-persistent desktop, which means App Volumes and UEM or 3rd Party (Liquidware). Best home for user and profile data is Acropolis File Services(AFS). VDI is scale out, so should your NAS.
    3) Easy restore of user files setting on AFS.
    4) Easy DR for AFS.
    5) AFS Home Share can spread over mutiple VMs allowing for only 1 Group Policy to manage.
    6) Data locality for boot storms if you’re not using instant-clones and protection from noisy neighbour under load.
    7) 2nd Copy of all data is placed based on capacity and performance to help with #5.
    8) Shadow Clones and inline-dedupe for App Volume for in-memory Applications.
    9) One Click Upgrades to get features, maintenance and security fixes without having to upgrade ESXi.
    10) Over 400 health checks to make sure your desktops run smoothly.


    NTC Pro Tip: Volume Groups to Save Bandwidth

    Nutanix Technology Champion

    Today there is no way to exclude certain disks from being replicated with protection domain on Nutanix. If you have a database that your dumping backup files to it can be problematic. To get around the problem you can use a Volume Group for the backup drive. When you go to select your SQL VM make sure to unselect “auto protect related entities” if you have Nutanix Guest Tools as it will automatically add the Volume Groups for you.

    By using a volume group on AHV and ESXi, ADS will automatically hosts the vDisks on nodes that are lightly loaded if load becomes heavy. No user action need. One-Click, so you can find another problem to pound your head against the desk for. 🙂


    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.
