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…
Determine correct system storage settings for compression, deduplication, erasure coding and validate expected savings
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…
Monitor CPU/Memory utilization to identify problems and propose solutions
Metric Chart Create a chart with an analysis focus on metrics like IOPs, Latency, or Bandwidth. Can have more than one (1) selected Entity. Analysis of multiple Entities against a single Metric. Entity Chart Create a chart with a focus on an entity like a Host or a Virtual Machine. Can have more than one…
Describe and monitor storage performance and methods of optimization
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…
