In the digital economy, most applications need to provide a 24*7 Service-Level Agreement (SLA) for every customer. The IT service department provider often faces the problems of how to make applications available at any time, how to handle Life Cycle Management (LCM), how the system infrastructure can automatically scale up and out, and so on. Most traditional infrastructure architecture has some hardware and software limitations; it cannot fulfill these requirements. You may need to integrate third-party hardware and software to fulfill these requirements. However, this will increase the cost of the total solution. When new software packages or patches are released, they need to upgrade or apply the patch to the existing traditional infrastructure architecture. At this moment, some compatibility problems between the hardware and software may exist, which is why traditional infrastructure architecture is not a good solution.

With the Hyper-Converged Infrastructure (HCI) platforms available on the market, most technical limitations of traditional infrastructure architecture can be resolved. The HCI platform can simplify most day-one deployment and day-two management activities. Dell VxRail Appliance is an HCI platform developed by Dell EMC and VMware. VxRail Appliance can provide different features, for example, hardware scaling, software package upgrade, centralized management, and LCM. In this chapter, we will discuss the VxRail system; you will get an overview of the VxRail Appliance 7.x platform.

This chapter includes the following main topics:

• What is VxRail Appliance?
• Dell VxRail architecture
• Dell VxRail features
• Dell VxRail management
• Dell VxRail documentation and resources

VxRail Appliance (as seen in Figure 1.1) is developed and powered by Dell EMC and VMware. It is an HCI appliance that is exclusively integrated and preconfigured with VMware vSphere and Virtual SAN (vSAN). VxRail platforms are fully integrated with VMware vCenter Server Appliance (VCSA) and use a VxRail Manager plugin for vCenter. The VxRail platform provides user-friendly and centralized management; system administrators can perform day-to-day activities using the VxRail Manager plugin for vCenter in a Hypertext Markup Language revision 5 (HTML5) interface:

The following table shows a summary of hardware configurations on each VxRail Series:

Table 1.1 – A summary of hardware configurations on each VxRail Series

The VxRail Appliance 7.x platform supports three types of VxRail nodes, including a VxRail node with vSAN, a VxRail dynamic node, and a VxRail satellite node. We will discuss the details in Chapter 2, Benefits of Hyper-Converged Infrastructure.

What is inside VxRail Appliance?

VxRail Appliance is a black-box solution developed by Dell EMC and VMware. VMware vSphere is preinstalled and configured on each VxRail Appliance before shipping to customers. In VxRail Appliance, there are three key elements:

• VMware SDDC technologies
• VxRail HCI system software
• Data protection options

This table shows a summary of the software inside VxRail Appliance:

Table 1.2 – A summary of the software inside VxRail Appliance

With the preceding table, we know what components make up each key element. Now we will discuss each piece of software.

VMware SDDC technologies

The following is a list of SDDC technologies:

• VMware vSAN is Software-Defined Storage (SDS) that is embedded in the kernel with VMware vSphere. You can choose the edition of VMware vSAN based on your requirements when you buy VxRail Appliance, including Standard, Advanced, Enterprise, and Enterprise Plus. Each VxRail Appliance is enabled by the vSAN feature when you power it on for the first time.

Important Note

In VxRail 4.7 or above, the VMware vSAN license is not embedded in each VxRail node. The vSAN license is enabled in the evaluation mode on each node when the customer powers it on for the first time. They need to add the vSAN license manually to each node.

• VMware vCenter Server is a central management dashboard that is used to configure and manage virtual machines. The VCSA instance license is preinstalled on VxRail Appliance. VCSA is a virtual appliance that is fully integrated with VxRail Appliance using the VxRail Manager plugin; we can manage VxRail appliances via VMware vCenter Server with the VxRail Manager plugin.

Important Note

The embedded vCenter instance license is bundled on VxRail Appliance. If you deployed the external vCenter Server for VxRail management, the optional vCenter Server instance license is required.

• VMware vRealize Suite is a cloud-based management software package that integrates VMware vRealize Cloud Management products, including vRealize Automation, vRealize Operations, vRealize Log Insight, and LCM on-premises. You can enable VMware vRealize products on the VxRail Appliance system at any time.
• VMware ESXi is a hypervisor that virtualizes the physical resources (for example, CPU processors, memory, storage, and networking) on the different virtual machines.

Important Note

VMware vSphere licenses are not included in VxRail Appliance. The customer can reuse existing vSphere licenses or order new licenses for each VxRail node.

• VMware Tanzu is used for modernizing your applications, which helps customers execute and manage different Kubernetes (K8s) clusters across the multicloud platform.
• VMware Cloud Foundation (VCF) is used to build up the Software-Defined Data Center (SDDC). This platform can deliver a variety of features, including VMware vSAN, VMware NSX, and VMware vRealize features.

Important Note

VMware Tanzu and VCF are optional features on VxRail; both features are not included in VxRail Appliance.

VxRail HCI system software

The following is a list of VxRail HCI system software:

• VxRail Manager is predeployed on VxRail Appliance, and it is fully integrated into VCSA with the VxRail Manager plugin. You can execute daily operations via the VxRail Manager plugin; these tasks include system scale-up and scale-out, automatic deployments, LCM, and maintenance tasks.
• SaaS multicluster management is a Dell EMC cloud platform. SaaS multicluster management collects telemetry data from each node in the VxRail cluster via the Secure Remote Services (SRS) gateway and can deliver the proactive system monitoring of VxRail Appliance systems.
• RESTful APIs are a bundled feature on VxRail Appliance that can execute management functions.
• Automation and orchestration services include VxRail Manager delivering the automated deployment and orchestration workflow in the VxRail Appliance system, for example, system scale-up and scale-out, LCM, and an active-active solution.
• Ecosystem connectors are used to integrate the software and hardware for LCM in the VxRail cluster, including automation and orchestrating services.

Data protection options

Dell EMC RecoverPoint for VMs (RP4VM) is a Continuous Data Protection (CDP) solution from Dell EMC. It can provide protection of the virtual machine with its point-in-time synchronization or asynchronization in a local VxRail cluster or across VxRail clusters between two different locations. You can manage RP4VM directly via VCSA.

Important Note

The RP4VM license includes 5 virtual machine licenses per node (E, P, V, D, and S Series) and 15 virtual machine licenses per chassis for the G Series.

VMware vSphere Replication (VR) is a disaster recovery solution at the hypervisor level; it can deliver data protection of the virtual machine with a 5-minute Recovery Point Objective (RPO) in a local VxRail cluster or across VxRail clusters between two different locations. You can manage VR directly via VCSA, and it also can work with SRM to deliver the automated failover and failback recovery plan.

Important Note

VMware SRM is the optional license for enabling disaster recovery on VxRail Appliance.You need an SRM license with at least 25 virtual machines per site.

Now that we understand which software components are bundled with VxRail Appliance, let’s look at the licensing options.

VxRail licensing

VxRail Appliance is a turnkey solution that is bundled with some software licenses on each VxRail node. It includes the following bundled VMware and Dell EMC software licenses:

• VMware vCenter Server
• VMware vSphere
• VMware vSAN
• VMware vRealize Log Insight

• Dell EMC RecoverPoint for Virtual Machines

VxRail Appliance also follows a Bring-Your-Own (BYO) vSphere license model. You can purchase VxRail Appliance with a new vSphere license or reuse any existing qualified vSphere licenses. The VxRail system supports several VMware vSphere license editions; it includes Enterprise Plus, Standard, and ROBO (Remote Office Branch Office) editions.

This table shows the difference between the preceding-supported vSphere licenses:

Table 1.3 – The difference between the preceding supported vSphere licenses

Important Note

VMware vSphere Essentials and Essentials Plus are not supported with VxRail.

VxRail software 4.7 or above also supports a flexible vSAN license model. You can purchase VxRail Appliance with different editions of the vSAN license. This table shows an edition comparison:

Table 1.4 – VMware vSAN editions feature comparison

This table shows an edition comparison for vRealize Operations Advanced:

Table 1.5 – VMware vRealize Operations Advanced edition feature comparison

A VMware vCenter Server Standard instance license is bundled with the VxRail cluster. VxRail Manager applies this license to the embedded VCSA during VxRail initialization.

Important Note

Transferring an embedded VCSA license to any vCenter Server is not supported. You need to prepare a new vCenter Server license for the external VCSA if you choose external VCSA during VxRail initialization.

The preceding tables help you choose the different types of VMware vSphere and vSAN licenses for VxRail Appliance based on your required functions and features.

Now that we understand VxRail Appliance and the different components and technologies used in it, let’s move on and learn about its architecture next.

The VxRail system is a turnkey solution that has been tested and validated by Dell EMC. Each VxRail node is built on a Dell PowerEdge server, and it includes the following hardware components:

• Intel Xeon Scalable processors (single, dual, or quad), up to 40 cores per processor, or an AMD EPYC processor with up to 64 cores.
• Up to 48 DDR4 Dual In-Line Memory Modules (DIMMs), it supports memory capacity ranging from 64 GB to 8,192 GB.
• A mirrored pair of BOSS SATA M.2 cards that are used to store the ESXi system on the node.
• A 10/25 GbE Network Daughter Card (NDC) used for VxRail’s predefined network connections.
• If you purchase a VxRail Hybrid node, it includes a single Solid State Drive (SSD) for the cache tier and multiple Hard Disk Drive (HDD) disks for the capacity tier.
• If you purchase a VxRail All-Flash node, it includes a single SSD or NVMe for the cache tier and SAS SSD, SATA SSD, vSAS SSD, or NVMe for the capacity tier.

Important Note

Each VxRail Series can support different maximum software and hardware configuration, for example, the number of vSAN disk groups, the number of additional network adapters, or the total number of memory and CPU cores.

Now, we will look at a diagram for the VxRail 7.0.xxx platform:

Figure 1.8 – A diagram of the VxRail 7.0.xxx platform

Figure 1.8 shows the following hardware components in this environment:

• There are four VxRail P670 Hybrid appliances (a minimum of four nodes is the recommended configuration). Each node installs an NDC with four 10 GB SFP+ ports. Two 10 GB ports are used for vSAN and vMotion networks; the other 10 GB ports are used for management and virtual machine networks.
• Two 10 GB network switches are used for VxRail’s network connectivity.
• One 1 GB network switch is used for Integrated Dell Remote Access Controller (iDRAC) connection on each VxRail Appliance.

Important Note

The minimum initial configuration of a VxRail cluster is three nodes; these three nodes must be the same model.

Now, we will discuss the logical diagram for the VxRail 7.0.xxx platform. Figure 1.9 shows the following software and hardware components in this environment:

• One VxRail 7.x cluster with four VxRail nodes, and there is a vSAN datastore across these four nodes
• One VxRail Manager virtual appliance
• One VCSA

Figure 1.9 – The logical diagram for the VxRail 7.0.xxx platform

Important Note

In VxRail 7.0 or later, there is no VMware vCenter Platform Service Controller (PSC), and vRealize Log Insight deploys automatically into the VxRail cluster during initialization.

In Figure 1.9, there are four nodes with the same model (VxRail P670) connecting to the VxRail network during VxRail initialization; then it can automatically build the VxRail cluster, and vSAN features are enabled on the VxRail cluster. By default, there are two VxRail system virtual machines that will be deployed into the VxRail cluster; they are VxRail Manage and VCSA. You can easily build the VxRail cluster in Dell EMC VxRail Deployment Wizard when every requirement is ready. You can refer to Figure 1.10 for the VxRail initialization:

Figure 1.10 – Welcome page of VxRail 7.0

Important Note

Please note that you can choose the VxRail software edition when you purchase VxRail Appliance: VxRail 4.7 or 7.0. VxRail 4.7 is shipped with VMware vSAN 6.7. VxRail 7.0 is shipped with VMware vSAN 7.0.

In this section, we understood the architecture of the VxRail system and the VxRail system’s virtual machines. Next, let’s look at its features.

The VxRail system can deliver different features; it includes automatic deployment, flexible scale-up and scale-out, Storage Policy-Based Management (SPBM), LCM, a single management dashboard, CDP, and a single-vendor, end-to-end ongoing support service. In day-one deployment, you can select the cluster type and then deploy the VxRail cluster and configure the SDS automatically. Compared to the traditional server storage architecture, it can minimize the deployment and configuration time. In Figure 1.11, you can see how you can select the type of the VxRail cluster in Dell EMC VxRail Deployment Wizard.

Figure 1.11 – Specifying the type of the VxRail cluster in Dell EMC VxRail Deployment Wizard

You can perform all operation tasks via VMware vCenter Server with the VxRail Manager plugin after the VxRail deployment is completed. In the VxRail Manager plugin, you can see all functions, such as Updates, Certificate, Market, and Add VxRail Hosts.

Figure 1.12 – VxRail System information

Storage Policy Based Management (SPBM) is a core feature in the VxRail cluster; the system administrator can define the availability, storage rules, and advanced policy rules. In the Availability tab, you can choose No data redundancy, 1 failure - RAID-1 (Mirroring), and 1 failure - RAID-5 (Erasure Coding). You can refer to Chapter 4, Design of vSAN Storage Policies, for more details.

Figure 1.13 – Defining the storage rules of the virtual machine storage policy

VxRail’s architecture supports flexible scale-up and scale-out. The compute and storage resources can be increased and rebalanced when adding a new node to the existing VxRail cluster (Figure 1.14). You can refer to Chapter 5, Design of Cluster Expansion, for more details:

Figure 1.14 – The Add VxRail Hosts dashboard

When a system has been live for a few years, operating system and system patch upgrades are required. In a traditional server storage environment, the system administrator may spend a lot of time on the preparation and compatibility verification before the system upgrade.

LCM is one of the key features of VxRail Appliance; VxRail’s one-click upgrade feature can easily handle LCM. The system administrator can easily upgrade the VxRail system with a single image that is prevalidated with Dell EMC and VMware. They can perform a one-click upgrade in vCenter Server with the VxRail Manager plugin (Figure 1.15). The single image includes VxRail Manager, VCSA, Dell PTAgent, VxRail Manager VIB, and VMware ESXi:

Figure 1.15 – The VxRail software update dashboard

Dell EMC RP4VM can provide data protection of the virtual machine with its point-in-time snapshots in a local VxRail cluster or across VxRail clusters between two different data centers. You can refer to Chapter 9, Design of RecoverPoint for Virtual Machines on VxRail, for more details.

VxRail’s support service can deliver single-vendor support from Dell’s support team. When the customer issues a request to Dell’s support team, they can handle and resolve the Dell and VMware technical problems. This support service works with Support Connect Gateway (SCG); it includes three types of service support-level agreements, Basic, ProSupport, and ProSupport Plus. You can refer to Figure 1.16 for details:

Note

SRS is replaced with SCG in VxRail 7.0.350 and above; it can deliver a single connectivity technology for Dell EMC products, such as server, data storage, and hyper-converged solutions. It can proactively monitor system health and create a case automatically over a secure connection.

Figure 1.16 – A comparison of Dell support services; this information is copyright of Dell Technologies (https://www.delltechnologies.com/asset/cs-cz/services/support/briefs-summaries/prosupport_enterprise_suite_brochure.pdf)
