The VxRail Advantage – Management Overview
The purpose of this Sample Question Set is to provide you with information about the Dell EMC VxRail Specialist for Implementation Engineer exam. These sample questions will make you very familiar with both the type and the difficulty level of the questions on the DES-6322 certification test. To get familiar with real exam environment, we suggest you try our Sample Dell EMC VxRail Specialist Certification Practice Exam. This sample practice exam gives you the feeling of reality and is a clue to the questions asked in the actual Dell EMC Certified Specialist – Implementation Engineer – VxRail (DCS-IE) certification exam.
These sample questions are simple and basic questions that represent likeness to the real Dell EMC DES-6322 exam questions. To assess your readiness and performance with real time scenario based questions, we suggest you prepare with our Premium Dell EMC VxRail Specialist Certification Practice Exam. When you solve real time scenario based questions practically, you come across many difficulties that give you an opportunity to improve.
Find out what you need to know as you investigate if Dell EMC VxRail HCI with vSAN hyper-converged software meets the needs of your organization’s workloads and use cases.
The VxRail appliance combines Dell EMC PowerEdge servers with VMwares vSAN storage virtualization software to deliver a turnkey, rackscale appliance that aims to ease hyper-converged infrastructure deployment. Dell EMC and its VMware subsidiary are market leaders in the hyper-convergence market.
A software-defined infrastructure, hyper-convergence consolidates compute, storage and network resources and hypervisors into highly scalable appliances called nodes that form a cluster with a minimum of three nodes. If additional storage or compute power is needed, admins can just attach an additional node to the cluster.
According to the latest numbers from IDC, Dell and VMware hold the largest share of the hyper-converged branded and software market categories, respectively. IDC reported in its September 2019 Worldwide Quarterly Converged Systems Tracker that Dell Technologies led the hyper-converged infrastructure (HCI) market in branded revenue, with $533.2 million in revenue, accounting for 29.2% of the market. VMware landed on top in the hyper-converged software category with $694.1 million in revenue, making up 38% market share.
The overall success of vSAN, with more than 20,000 customers, and the tight integration of Dell and VMware since the former acquired EMC in 2016 are the main reasons for this HCI dominance. The most visible example of this success is the co-engineering of the VxRail appliance.
In this article, we explore some of the basics of VxRail and this partnership for organizations considering using an HCI deployment and cluster based on the VxRail appliance for their data center. We examine what VxRail is, how it works and the versions of the appliance that have been optimized for different use cases and workloads. We also learn about VxRail management, security, backup and business continuity, as well as how the VMware Cloud Foundation (VCF) on VxRail extends the VMware-Dell EMC partnership to simplify the deployment of hybrid private clouds.
The Dell EMC VxRail appliance is a hyper-converged infrastructure product based on VMware vSAN storage virtualization software.
As far as maximum size, the math is easy: up to 64 nodes in a cluster, and each server supports up to 35 capacity devices (five disk groups, seven capacity devices each). A bit of quick math yields a max of 2240 capacity devices. Using 4TB drives, that’s just shy of 9PB raw in a single cluster. Probably more than you need.
Not really. Although we support 1Gb, 10Gb is highly recommended. Our internal testing shows that you need to get into nosebleed multi-million IOPS territory before network overhead even starts to become a factor. For those folks (and they are out there!), there’s 40Gb. We also have a deep-dive network design guide if you’re doing a very large multi-rack cluster.
However, for many customers, manageability is the big win. As the VDI admin creates user pools and assigns policies for performance, protection and persistence — all of that just flows downwards to vSAN via a shared policy mechanism. That means that the admin can easily reconfigure their VDI environment without having to explicitly reconfigure an external storage array. We hear that’s a pretty cool feature.
The second is sizing. Some VMware admins try to design their own configs, and are rather new to storage. They might not understand the performance implications of using, say, a single 4TB 7200 RPM NL-SAS drive vs. four 1TB 10K SAS drives — or might try to use super low-end components.
You can achieve a similar effect with vSAN by setting the striping policy to a higher number. This will be effective for smaller numbers of VMs, but loses effectiveness if the entire cluster is busy. However, we’d encourage you to test what you actually plan to use — which most often is multiple VMs on a cluster, each doing different things.

FAQ
What is VxRail used for?
What are the components of VxRail?
The VxRail minimum cluster configuration consists of three nodes with a maximum of 64 nodes. VMware two-node models hold one to two nodes in a rack mount chassis. Provides a software stack for SDDC building blocks that include compute, network, storage, and management.
