An administrator is designing a vSphere cluster with the VSAN default policy. The requirement is to maintain full redundancy of data and virtual disks during any patching or maintenance of this cluster.
What is needed to meet the needs of this scenario?
Show answer details
Correct answer: A
Explanation:
When not using a witness, there is a minimum requirement of 3 ESXi hosts in a vSAN cluster. This is the same for all versions. While vSAN fully supports 3-node configurations, they can behave differently than configurations with 4 or greater nodes. In particular, in the event of a failure there is no way for vSAN to rebuild components on another host in the cluster to tolerate another failure.
Also with 3-node configurations, vSAN does not have the ability to migrate all data from a node during maintenance.
Design decision: Consider 4 or more nodes for the vSAN cluster design for maximum availability References: VMware vSAN Design and Sizing Guide. Page: 51 - 6
Which VMware-recommended tool provides specific information on the best strategy for a vSAN deployment?
Show answer details
Correct answer: B
Explanation:
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 pre-configured, 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: • Pre-installed Hyper-Converged Infrastructure Software • Bundled Hyper-Converged Infrastructure Software licenses . Single vendor support from the server vendor to cover both hardware and Hyper-Converged Infrastructure Software
Incorrect answers:
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.
