PowerShell Interactive Mode (add-pssnapin) The PowerShell Interactive Mode allows you to run individual PowerShell commands inside the PowerShell mode. View some of the PowerShell cmdlets here. The Add-PSSnapin command allows you to load Nutanix PowerShell cmdlets into the PowerShell environment. Convert the raw password to a secure string. This step is required because the Nutanix…
Postman Powerful HTTP client for testing web services. Makes it easy to test, develop and document APIs by allowing users to quickly put together both simple and complex HTTP requests. Google Chrome app for interacting with HTTP APIs. It presents you with a friendly GUI for constructing requests and reading responses. Offers an add-on package…
Understanding REST API REST API is also known as Web Services API because behind the scenes, REST API calls are nothing but HTTP requests used to retrieve information from, or making changes to, the cluster. Response Codes In response to an HTTP request, the server (cluster) returns a HTTP response which carries a Response Code….
Jumbo Frames Due to the additional network configuration required, Nutanix does not recommend configuring jumbo frames on AHV for most deployments. However, some scenarios such as database workloads using Nutanix Acropolis Block Services (ABS) with iSCSI network connections can benefit from the larger frame sizes and reduced number of frames. To enable jumbo frames, refer…

I covered Compression, Deduplication, and Erasure Coding in the NCP Study Guide. However, there’s always more to learn! Compression Workloads Recommended for Compression Almost all Workloads Not Ideal for Compression Encrypted datasets Already compressed datasets (for example, images, audio, or video) Deduplication Workloads Recommended for Deduplication Base images (cache)—you can manually fingerprint them using vdisk_manipulator P2V and V2V when using Hyper-V (ODX…
Capacity Runway Capacity Runway focuses on consumption from three resource buckets, which include Storage capacity CPU Memory The capacity runway shows the number of days remaining before a resource is consumed. The multi-cluster view is shown as a table and individual cluster is shown as a graph. It uses machine learning algorithms to forecast capacity….
What is X-FIT? X-FIT is a distributed time series analysis and forecasting system that uses an ensemble of models. The models compete in a distributed tournament, where the system performs cross-validation and selects the top models based on the mean absolute scaled error (MASE) on the out-of-sample forecasts during the cross validation. Then the final…
