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.

xtract

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.

Test

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. 🙂
