It’s been over a decade since hyper converged infrastructure (HCI) disrupted technology. An ideal architecture for HCI would be a simple, modular architecture, in which all datacenter components (compute, storage, and networking) are consumed in a virtualized way to simplify allocating and managing resources. With this architecture, all physical components reside in the same box. When we combine these boxes, we can scale our datacenter power in all resource domains to accommodate almost any type of workload. This is due to extremely fast processors, large and efficient storage devices, and advanced network connections.
If we abstract the hardware layer in this architecture and imagine a solution that fills all the roles previously described, (virtualization of the three infrastructure domains, compute, network and storage) VMware can easily come to mind. VMware has a strong portfolio of software defined compute (vSphere), storage (vSAN), and networking (NSX family) to create a best of breed hyper-converged infrastructure product.
It will come as no surprise that VMware leads the HCI market due to its vSAN based systems, as reported by IDC1:
In this VMware led market, Dell PowerEdge servers stand out as a logical choice in terms of providing the modular box (server), for this hyperconvergence paradigm. Dell Technologies, as a global server market leader (Worldwide Server Market, IDC), has a long tradition of Ready Systems that allow a simpler customer deployment experience.
Dell EMC vSAN Ready Nodes (vSAN Ready Nodes) are a great example of an HCI implementation, providing a robust and mature datacenter platform — pre-configured, tested, and certified to run VMware vSAN.
This HCI market is especially relevant as its current growth rate far surpasses that of the server market. According to Gartner2 while the server market is growing at 5.6%, the HCI market is increasing by 23 percent (IDC3). That represents a growth rate more than four times that of the server market:

In this prosperous landscape, Dell Technologies holds an outstanding leading place, with a wide portfolio of HCI offerings, led by Dell EMC VxRail in tandem with vSAN Ready Nodes. More than 20 years of collaboration endorses the relationship between Dell Technologies and VMware, specifically in the server space, where we have worked to simplify our joint customers’ technology experience.4
Dell EMC Ready Nodes simplify and accelerate infrastructure modernization providing IT a strategic advantage with their flexibility, simplified operations, and breadth of choice.
This leadership is founded on four pillars:
- Form factors: Dell Technologies offers an unmatched portfolio of vSAN Ready Nodes options, ranging from 1 to 2U rackmount servers, tower models, and MX series blade options. There are more than 250 different configurations available for Dell EMC vSAN Ready Nodes. As part of this rich offering, Dell provides unique solutions that scale up to four processors per node.
- Identity Module: This module declares the system a vSAN Ready Node, distinguishing it from a standard off-the-shelf server. All vSAN Ready Node capabilities derive from this Identity Module, facilitating the Day 0 operations provided by vLCM in unison with OMIVV.
- OMIVV (OME): The Dell EMC Open Manage Integration for VMware vCenter (OMIVV) is designed to streamline the management processes in your data center environment by allowing you to use VMware vCenter Server to manage your full server infrastructure, both physical and virtual.
- vSphere Lifecycle Management (vLCM): Consistency across ESXi hosts is essential for creating reliable and high performing platforms, but it is difficult to obtain, especially at scale. vLCM solves the complexity by enforcing consistency across ESXi hosts in a cluster using a declarative model. vLCM not only accomplishes this by using an ESXi base image but extends it with the desired state for firmware and driver versions as well.

Today, most technology companies in the IT space work to offer customers not only the best technology innovations but also those that help simplify their day-to-day lives.
One example of this is the new vCenter plug-in for NSX-T, introduced with vSphere 7.0 Update 3c and NSX-T 3.2. Through this new deployment method for NSX-T, management and operations users can now use NSX-T as a plug-in for vCenter, similar to how earlier versions of NSX were configured. Through wizard-assisted operations, security policies can easily be configured, deployed, and operated within vCenter.
Figure 1. The new vCenter plug-in for NSX-T simplifies security deployment and operations
For Dell HCI platforms such as VxRail, vSAN Ready Nodes, and PowerEdge servers hosting vSAN-based workloads, NSX becomes an optimal network and security engine.
Figure 2. Dell HCI platforms such as VxRail or vSAN Ready Nodes become the perfect targets for the new vCenter plug-in
The whole process is simple. It can be completed by following these steps:
- Install NSX-T Manager and provide a license key.
- Install the new method to configure and operate NSX security, the vCenter plugin for NSX.
- Configure the distributed firewall policies for the HCI cluster:
a. Define infrastructure services as needed (DNS, DHCP, custom…).
b. Create the environment to consume the defined infrastructure services.
- Define how the elements in the environment can communicate with each other.
- Define communication strategies for applications in the environment.
- Review and verify the defined security policies before they are published and effective.

The Benefits of Composable Infrastructure for VMware Cloud Foundation on vSAN Ready Nodes
Thu, 25 Aug 2022 17:14:52 -0000|

Discussions comparing the public cloud to on-premise architectures have shifted to discussions about the best way to build a hybrid model.
Multi-cloud delivery services alongside on-premise infrastructure seems to provide the versatility that organizations need for business critical missions, however they are often complex and costly. Ending up with multiple administrative teams, toolkits, and processes doesn’t appeal to most organizations as a winning horse.
As usual, simplicity comes to our rescue. An integrated offering that provides customers with the advantages of both the public cloud and an on-premise infrastructure helps organizations with the following:
- Control infrastructure price and performance
- Improve their deployment times and thus time to value
- Minimize cost and complexity, through a single set of skills and tools
Most organizations that are interested in these benefits are not prepared to build a hybrid cloud themselves. Running an on-premise datacenter or building assets in the main public cloud tends to be more familiar for most IT teams, but managing both at the same time may be beyond the capabilities of some existing IT teams.
In these cases, a trusted partner that brings guidance and innovation to follow this path is crucial. Such a partner can provide a set of familiar management tools with all the administrative and analytics capabilities required to monitor business workloads—such as tools that can be extended to multiple public cloud providers, giving organizations the advantages of compelling cost, efficiency, and speed.
Because most organizations today are using virtualized on-premise infrastructure, VMware comes to my mind as a perfect partner for this journey, having a mature technology offering to help companies build a hybrid cloud.
VMware on Dell offers infrastructure to build a foundational hybrid cloud. This architecture makes the on-premise more cloudy and enables workload mobility to place every workload, whether it is in a public cloud or in our on-premise infrastructure.
Dell PowerEdge MX offers a software defined data center that empowers organizations towards a hybrid cloud model. For example, when this infrastructure is coupled with VMware Cloud Foundation (VCF) and VMware on AWS organizations can build a hybrid cloud using popular VMware tools and capabilities.
Figure 1: MX composable infrastructure chassis
MX chassis is built with capabilities that perfectly match vSAN requirements. Each node can hold six drives, which ensures that that two of the drives are caching devices within the vSAN cluster for optimal performance.
A low latency smart fabric is built into the MX design. This minimizes the risk that lack of throughput or excessive latency presents for a hybrid cloud deployment. Expandable and extensible by design, the MX family can deliver cloud value across many technology generations.
Dell MX management is integrated with VMware Cloud Foundation 4.x. The MX hardware has the systems’ management and APIs to hook into the VMware consoles that customers are used to. This way we can deploy VCF into the MX infrastructure though a simplified path that eliminates tedious stepwise processes around setup, monitoring, provisioning, and management.
Dell and VMware have also worked together to improve telemetry and insight, giving operators an improved view of resource utilization for each node and chassis in the MX infrastructure.
In summary, the advantages of running VCF on Dell vSAN Ready Nodes based on PowerEdge MX servers include:
- A scalable network design that provides a low latency, automated and not oversubscribed fabric to support any workload deployment the business may need
- A secured stack all the way from the hardware to the VMware management console
- An integrated management with tool set that helps IT admins provision, monitor, and maintain their MX based vSAN Ready Node farm. One console can manage multiple chassis and even other server and storage types.
Figure 2: MX integrated management simplifies hybrid cloud operations
One way to see the integration of VCF with MX based vSAN Ready Nodes in action is to deploy a new workload cluster of Dell vSAN Ready Nodes MX750c into an existing VCF infrastructure.
Principled Technologies performed this test and showed how simple and straightforward the expansion process is with MX servers. They also showed, by following the same expansion process with two generations of MX servers (MX740c and 750c), that the tools and processes remain the same across server generations.
The engineers completed the expansion process in just two hours and 21 minutes. It took the same time for each of the two server generations.
For more information about this test case, see the Principled Technologies report.
Although building a functioning hybrid cloud to support real business workloads may look complex, it can be simplified if by using the proper technologies and tools. VCF combined with Dell vSAN Ready Nodes MX composable infrastructure offers a perfect duo to reach an organization’s hybrid cloud goals.
