Correct Answer: CDE

One of the Space Efficiency features of Virtual SAN 6.2 that is available for both All-Flash and Hybrid configurations, is the introduction of Sparse Virtual Swap files. Swap files on Virtual SAN by default, are created with the .vswp 100% reserved. In a thin provisioned/guaranteed capacity perspective, it could be said that they are effectively Lazy Zeroed Thick (LZT).

RAID-5/6 erasure coding is a space efficiency feature optimized for all-flash configurations of Virtual SAN

6.2.

Virtual SAN 6.2 introduces space efficiency features optimized for modern all-flash storage, designed to

minimize storage capacity consumption while ensuring availability. One of these features is near-line

deduplication and compression.

Correct Answer: ABE

A:

1.

Navigate to the vSAN cluster in the vSphere Web Client Navigator, and select a host.

2.

Click the Monitor tab and click Performance.

3.

Select vSAN - VMkernel Adapters, and select a VMkernel adapter, such as vmk1. Select a time range for your query.

4.

vSAN displays performance charts for the VMkernel adapter, including throughput, packets per second, and packets loss rate.

BE: When the performance service is turned on, the cluster summary displays an overview of Virtual SAN performance statistics, including Virtual SAN IOPS, throughput, and latency. At the cluster level, you can view detailed statistical charts for virtual machine consumption and the Virtual SAN back end.

Correct Answer: D

vSAN ReadyNode Configurator Selecting a vSAN ReadyNode is simple. Choose the vSAN version you want to deploy, pick a ReadyNode profile based on your specific needs, select your preferred server vendor, and then pick one of the available models.

Note: vSAN ReadyNode are x86 servers, available from all the leading server vendors, that have been preconfigured, tested and certified for VMware Hyper-Converged Infrastructure Software. Each ReadyNode is optimally configured for vSAN with the required amount of CPU, memory, network, I/O controllers and storage (SSDs, HDDs or flash devices).

Some ReadyNode are available with additional options aimed at simplifying purchasing, deployment, and support. These options are only available for select server vendors and ReadyNode models:

1.

Pre-installed Hyper-Converged Infrastructure Software

2.

Bundled Hyper-Converged Infrastructure Software licenses

3.

Single vendor support from the server vendor to cover both hardware and Hyper-Converged Infrastructure Software

B: VMware Virtual SAN Sizing Tool All Virtual SAN customers and enthusiasts can easy get sizing ideas and estimations on the amount hardware resources necessary to support a particular Virtual SAN design. All you will need to do is provide a few virtual machine inputs based on capacity, performance, and availability requirements. The purpose of this tool is to help determine the hardware specifications for hosts in a Virtual SAN cluster required to run a set of virtual machines defined by a set of input characteristics.
