VMware vSAN and VMware NSX

Overview of NSX Data Center

VMware’s NSX offering is a network virtualization platform designed for the SDDC (Software Defined Data Center). It delivers security and networking in software form – totally abstracted from any underlying physical infrastructure.

It enables the Virtual Cloud Network, which provides an all-pervasive, secure end-to-end connectivity for data and apps wherever they live.

Overview of VMware vSAN

Providing a high-performance, vSphere-native architecture to power industry-leading hyper-converged infrastructure solutions, VMware’s vSAN is a core part of the SDDC. vSAN provides users with the ability to accelerate their business by providing hyper-converged infrastructure for cloud ubiquity, leading flexibility, and seamless evolution.

vSAN is native to leading hypervisor clouds and uses existing tools for computation and storage purposes, thus optimizing and protecting your current investments. It provides leading flexibility by extending to Digital Foundation and full stack HCI while unifying resources under policy-based management.

vSAN also ensures security for data-in-flight or at-rest while enabling consistent operations from edge to core to cloud.

The Correlation Between VMware vSAN and NSX

There are many questions about the interoperability and compatibility of VMware vSAN and NSX as well as various deployment scenarios around layer-2 and layer-3 network topologies.

The truth is that NSX co-exists well with vSAN and can be deployed on the same vSphere infrastructure without issues.

Although they co-exist together, none of them depends on the other to deliver services, resources and functionalities. It is easy to mix the use cases of these seemingly separated technologies by leveraging the great integration between them.

The vSAN network stack can be configured over layer-2 and layer-3 network topologies and can support flexible deployments out-of-the-box. Aside from keeping it isolated, vSAN’s network must be managed using the networking technologies that is recommended by VMware and suitable for its deployment. These include PIM, IGMP Snooping, IGMP, and IP Multicast.

vLANs are not consumed by logical networks and tenants created by the two technologies are securely separated. Also, two different tenants can create two distinct logical networks and router events within the same subnet range without impacting each other. All router and networks created by a tenant remain dedicated to that tenant.

Furthermore, NSX’s security features that were exposed through OpenStack allows tenants to create security groups that restrict both inbound and outbound traffic, and between instances of the same network.

Why Organizations Use VMware NSX

NSX prevents the lateral spread of threats by providing application-centric security at the workload level. It enables native security and networking for all containerized workloads across multiple application frameworks while reducing the compliance scope through isolation of the systems that transmit, process and store sensitive data.

VMware NSX streamlines multi-cloud operations and ensures security and networking consistency across heterogeneous sites. It also removes operational bottlenecks from all application frameworks and platforms by automating security and networking services.

The Enterprise Plus Edition of NSX provides users with the most advanced capabilities, as well as NSX Hybrid Connect for hybrid cloud mobility and vRealize Network Insight for security and network visibility operations.

Why Businesses are Turning to VMware vSAN

Organizations can run their most critical business solutions like SAP, Exchange and Oracle on vSAN with enterprise-level performance security and reliability. vSAN comes with an all-flash architecture capable of delivering 150,000 IOPS per node with sub-millisecond latencies. It enables reduced infrastructure costs by providing enterprises with the ability to start small and scale effortlessly as their needs evolve.

VMware vSAN delivers top-notch performance while reducing TCO over conventional storage arrays. By running VMs on clusters within the data center, vSAN allows your IT staff to deliver desktop services to end users.

It also enables users to manage their branch and remote offices with little or no need for on-site IT staff. It is a simple and cost-effective solution that can be easily managed from your main data center.

Users can choose from flexible licensing options – per CPU or per VM.

By simplifying management of disaster recovery operations even in remote sites (with no on-site IT staff), vSAN helps enterprises to lower their infrastructure and operating costs. When combined with VMware’s Site Recovery Manager, vSphere Replication and vSAN can be used to automate and orchestrate the recovery of multiple VM machines.

Businesses should leverage the NSX platform for scalable and flexible network virtualization without the limitations of typical multitenant network environments. They can also use a vSphere-native, software-defined storage solution – vSAN – to control IT costs, scale for future business needs and evolve their data center without risk.
