There are a number of additional considerations if you plan to deploy an all-flash vSAN solution:. Prior to starting the proof of concept project, the following pre-requisites must be met. The following assumptions are being made with regards to the deployment:. Choosing the appropriate hardware for a PoC is one of the most important factors in the successful validation of vSAN.

Bring your own : Organizations considering vSAN for existing workloads can choose their existing hardware. This is a virtual environment and is not a true test of performance or hardware compatibility but can help stakeholders feel more comfortable using vSAN. Hosted PoCs : Many resellers, partners, distributors, and OEMs recognize the power of vSAN and have procured hardware to make it available to their current, and future customers in order to be able to conduct vSAN proof of concepts.

There is no right or wrong choice, however choosing the appropriate hardware for a POC is vitally important. There are many variables with hardware drivers, controller firmware versions so be sure to choose hardware that is on the VMware Compatibility List.

Once the appropriate hardware is selected it is time to define the PoC use case, goals, expected results and success metrics. Understanding how the solution behaves on day-2 operations is important to consider as part of the evaluation. Adding hosts, migrating VMs between nodes, and cluster creation are some of the many operations that are consistent between vSphere and vSAN, resulting in a smaller learning curve, and eliminating the need to have storage specialists.

This particular test seems to get a lot of attention during a vSAN POCs, but it's important to understand the requirements of the environment and pay close attention to details such as workload profiles.

Ideally, having a clone of an environment for testing will yield the most accurate results during the test. On the other hand, a benchmark test can also be helpful as the test tends to be faster because there is no need to clone production VMs or do additional configuration. However, such tests require that you understand the workload profile to be tested.

Conducting such a test will require knowledge of testing tools like Oracle's vdbench, how to deploy and interpret it. To make this test easier for the public, there is a fling tool available called HCIBench, which automates the deployment of Linux VMs with vdbench as a way to generate load on the cluster.These additional settings are read upon boot up, and automatically configure networking for the appliance.

One of the features announced with vSAN 6. The witness component arbitrates ownership of the virtual machine resources in the event of a failure. VMware has provided this license in the appliance free of charge. This keeps customers from having to dedicate a physical ESXi host as a witness host and the licensing that would be required for the dedicated ESXi host. This is the first nested ESXi solution that is supported from VMware and comes preconfigured with the disk configuration and network adapters to connect to the VMware vSAN infrastructure.

Login to your VMware portal and download the appliance to be deployed. On the Select name and location screen, we choose the name of the vSAN Witness Appliance, the target Datacenter and folder location in which to deploy. Choose the Name Datacenter and folder.

Choose the VMware compute cluster. In mid deployment, we review the general configuration set for the OVA appliance itself before proceeding. Accept the EULA. On the select configuration screen, you choose the configuration sizing for the vSAN Witness node. The sizing configuration is broken down as follows:. Choose the network configuration for the Witness and Management networks and the portgroups they are attached to.

Review the configuration and begin deploying the appliance. Once the appliance is up and running, it can be used in configuring a stretched or a 2-node vSAN cluster. The free licensing provided from VMware adds to the potential cost savings benefits as well.

We apply the term dataset transformations to the set of operations to create new modified versions of your original dataset or just transformations to abbreviate. Keep in mind that you can sample, filter and extend a dataset all at once in only one API request. Also when cloning a dataset, you can modify the names, labels, descriptions and preferred flags of its fields using a fields argument with entries for those fields you want to change.
