VMware and Storage crazy man, vExpert, MN VMUG leader

Repost : What is vNIC, VMKNIC, PortGroups, Uplink Ports, vPorts and VMXNET3 Adapter

Studying NSX, I found that a review of the differences between vmnics, vNIC’s, and the terminology where in order.

 

I thought this blog post did a good job of over viewing the terms.

 

What is vNIC, VMKNIC, PortGroups, Uplink Ports, vPorts and VMXNET3 Adapter

 

Virtual Networking is one of the Key components of Datacenter. If all your Critical VMs running on highly redundant & high speed SAN or Ethernet Network but if VMs can’t communicate with each other then everything is useless.
From Functioning perspective, Virtual Network in VMware is similar to Physical Networks. Like Physical networking, Virtual networking is also exercises TCP/IP stack so nothing is changed underneath.
But Virtual networking has introduced many new components or its complex terminology which is sufficient enough to confuse any new admin or anyone who is trying to familiar with VMware Networking.

In this post, I will try to make you guys familiar with VMware Networking components, Its terminology and significance of each Networking Component.”

Netapp ‘s Soldifire HCI Overview at VMworld 2017 – Tech Field Day Extra.

Netapp ‘s Soldifire HCI Overview. I had a chance to get a overview of Netapp’s new HCI Product while at Tech Field Day Extra while attending VMworld 2017.

 

I’ve long been a fan of the Solidfire Technology. From the early day’s to after the purchase and the re-branding of the product into Netapp.

 

 

Solidfire has always been built on Guaranteed Performance, flexibility & scale, and automated infrastructure and the Netapp Solidfire HCI product is no different.

 

With Netapp’s HCI Architecture, you see standard services that you would across all Netapp Products.

Uila – A view into your data center.

I recently had the chance to get a product overview of Uila.

 

What product does Uila have?

 

“Uila’s Application-Centric Infrastructure Monitoring Monitoring helps align business and IT Operations goals in a single product by providing IT Operations with the application visibility and correlated network, compute and storage insights for Private, Public and Hybrid Cloud-based Data Centers (such as VMWare, Amazon AWS, Microsoft Azure, Google Cloud, Docker Container, etc.).  “

 

Ever need to see why your developer or application owner are indicating your virtual environment is causing performance issues to their application?? Of course, it’s not VMware, but it couple be something between the virtualization layer and the application layer causing performance issues.

 

 

 

 

Sounds Great. But what does that mean? How does it work?

 

 

 

 

How do I see into my environment ?

 

 

 

Uila Shows real time, and backwards in time so you can click and dig in.

 

 

Then you can dig into Application Analysis to see what is causing the problem.

 

 

Once you find the problem, in this case Oracle_11g-n1 looks suspect..  You can dig farther in.

 

 

 

Of course you can do a root cause view.

 

And find the problem.

Big Switch – Big Cloud Fabric

A overview of Big Cloud Fabric

 

Big Switch labels Big Cloud Fabric, the ” Next-Gen Data Center Switching Fabric

From the above Link.

Big Cloud Fabric™ is the next-generation data center switching fabric delivering operational velocity, network automation and visibility for cloud-native applications and software-defined data centers, while staying within flat IT budgets.

Enterprise data centers are challenged today to support cloud-native applications, drive business velocity and work within flat budgets.

Network layer is often cited as the least agile part of data center infrastructure,especially when compared to compute infrastructure. The advent of virtualization changed the server landscape and delivered operational efficiencies across management workflows via automation. Emerging cloud-native applications are expected to demand even greater agility from the underlying infrastructure.

Most data centers are built using old network architecture, a box-by-box operational paradigm that inhibits the pace of IT operations to meet the demand of modern applications and software-defined data centers. Click here for more information on the challenges.

Software-defined data center is demanding network innovation. With virtualization going mainstream, networks are required to provide visibility into virtual machines, east-west traffic across VMs, and deliver network service connectivity easily. Networks are expected to not adversely impact software-defined data center agility by mandating manual box-by-box network configuration and upgrades. Emerging cloud-native applications require rapid application and services deployment. This demands network operations to be more automated instead of relying on manual CLI and limited GUI workflows. Lastly, infrastructure budgets trends have flat-lined in most organizations. This demands an innovative approach compared to the legacy network based on proprietary hardware that increases costs.

These network demands are met by software-defined networking (SDN) solutions. Leveraging a centralized controller, the SDN networks overcome the box-by-box operational paradigm to deliver business velocity. As applications become more distributed, SDN approaches are required for networks to become agile and automated via orchestrated workflows using RESTful APIs. By leveraging open industry-standard network hardware, SDN solutions provide vendor choice and drives down costs in a flat budget environment. This cycle of innovation has been witnessed before in the server infrastructure, driven by virtualization and containers. More recently, storage infrastructure is getting transformed as well with various software-enabled architectures.

 

Lets Dig in. Below is a overview of the Clos Fabric.

 

What are my use cases? What type of deployments support the fabric?

 

 

Who uses the product today?

 

 

How do I deploy this with my existing data center, do I need to worry about my legacy network working with Big Switch?

 

What has defined customer success?

API’s are key, how do you leverage them for automation?

 

 

How do you enable me to out scale my competitors?

 

How do you allow me to see inside my network?

 

How do you support multi tenancy?

 

 

 

 

Thanks

Big Switch – Container Integration

I had a the opportunity of a Big Switch and Containers overview.

From the Big Switch Page above.

 

Single SDN Fabric for Multi-Container Ecosystems.

Big Cloud Fabric delivers network automation, deep visibility and rapid container-to-container troubleshooting in multi-container environments.

Containers are a new atomic unit of computing that is ideal for emerging cloud-native, distributed applications. Data center operators are evaluating various container technologies, including Docker, Kubernetes, Mesosphere and Red Hat OpenShift.

Containers offer a layer of abstraction, not unlike to what virtual machines offered when virtualization first arrived on the scene. However, Containers are lightweight in using the host footprint because they share an underlying operating system unlike a VM which hosts its own guest OS.

Comparison chart of VMs and Containers

Containers enable micro-services based distributed applications where an application is decomposed into multiple network-connected micro-services, with each micro-service packaged in its own container. This highly-distributed application architecture leads to tremendous increase in east-west traffic compared to monolithic applications.”

 

 

What about Bare-Metal networking Support?

 

 

Container Fabric Automation, Network visibility, and Operational Simplicity, what does that mean?

 

What about a example of container visibility?

 

 

How do I troubleshoot?

 

 

How about event monitoring, and logging?

 

Additionally watch the Big Switch Kubernetes Demo

Register Storage Providers for Virtual Volumes? Why VVOL’S?

One of the main reasons I wanted to upgrade my lab to vSphere 6.5 was to play with VVOL’s or Virtual Volumes.

Why VVOL’s? Good Question. Lets Look at what is new in Virtual Volumes.

 


 

See What’s New: vSphere Virtual Volumes

Source http://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/products/virtualvolumes/vmware-whats-new-vsphere-virtual-volumes.pdf

 

“By transitioning from the legacy storage model to Software-Defined Storage with Virtual Volumes, customers will gain the following benefits:

 

  • Automation of storage “class-of-service” at scale: Provision virtual machines quickly across data center using a common control plane (SPBM) for automation.
  • Self-Service capabilities: Empower application administrators with cloud automation tool integration (vRealize Automation, PowerCLI, OpenStack).
  •  Simple change management using policies: Eliminate change management overhead and use policies to drive infrastructure changes.
  • Finer control of storage class of service: Match VM storage requirements exactly as needed with class of service delivered per VM.
  • Effective monitoring/troubleshooting with per VM visibility: Gain visibility on individual VM performance and storage consumption.
  • Non-disruptive transition: Use existing protocols (Fiber channel, ISCSI, NFS) across heterogeneous storage devices.
  • Safeguard existing investment: Use existing resources more efficiently with an operational model that eliminates inefficient static and rigid storage constructs.

Sounds good, Since I have a Solidfire in my lab that supports it, and it’s enabled. Whats first?

 


 

The first step is to Register the Storage Provider.

 

“Your Virtual Volumes environment must include storage providers, also called VASA providers. Typically, third-party vendors develop storage providers through the VMware APIs for Storage Awareness (VASA). Storage providers facilitate communication between vSphere and the storage side. You must register the storage provider in vCenter Server to be able to work with Virtual Volumes.

After registration, the Virtual Volumes provider communicates with vCenter Server. The provider reports characteristics of underlying storage and data services, such as replication, that the storage system provides. The characteristics appear in the VM Storage Policies interface and can be used to create a VM storage policy compatible with the Virtual Volumes datastore. After you apply this storage policy to a virtual machine, the policy is pushed to Virtual Volumes storage. The policy enforces optimal placement of the virtual machine within Virtual Volumes storage and guarantees that storage can satisfy virtual machine requirements. If your storage provides extra services, such as caching or replication, the policy enables these services for the virtual machine.

Verify that an appropriate version of the Virtual Volumes storage provider is installed on the storage side. Obtain credentials of the storage provider.

1

Browse to vCenter Server in the vSphere Web Client navigator.

2

Click the Configure tab, and click Storage Providers.

3

Click the Register a new storage provider icon ().

4

Type connection information for the storage provider, including the name, URL, and credentials.

5

Specify the security method.

Action

Description

Direct vCenter Server to the storage provider certificate

Select the Use storage provider certificate option and specify the certificate’s location.

Use a thumbprint of the storage provider certificate

If you do not direct vCenter Server to the provider certificate, the certificate thumbprint is displayed. You can check the thumbprint and approve it. vCenter Server adds the certificate to the truststore and proceeds with the connection.

The storage provider adds the vCenter Server certificate to its truststore when vCenter Server first connects to the provider.

6

To complete the registration, click OK.

vCenter Server discovers and registers the Virtual Volumes storage provider.

Next up. Making a Datastore within it.
