VMWare NSX-T vs NSX-v: Complete Comparability

October 3, 2022

Virtualization has drastically modified the best way information centres had been constructed earlier. The vast majority of fashionable information centres use {hardware} virtualization expertise and deploy bodily servers as hypervisors to run digital machines on bodily servers. This improves scalability, flexibility and saves working prices.

Networks are essentially the most essential elements of information centres together with virtualized information centres the necessity for big and complicated community configurations for his or her virtualized environments. Software program outlined community structure goals to make the community agile and versatile sufficient to reply to altering enterprise necessities in a fast method.

VMware NSX is a community virtualization resolution which permits to construct software program outlined networks in virtualized information centres. NSX is available in two totally different flavours: NSX-v and NSX-T

At the moment we glance extra intimately about two flavours of NSX particularly NSX-v and NSX-T from VMware associated to virtualization of community assets utilizing NSX, their variations, benefits and so forth.

NSX-v was designed for vSphere deployments and architected on a single NSX-v supervisor platform tied to a single VMware vCentre server occasion. NSX-v is the unique NSX platform after VMware buy in 2012 for Nicira.

It’s tightly built-in with VMware vSphere and particular to vSphere hypervisor environments developed earlier than NSX-t. Deployment of NSX-v and t are fairly related. NSX supervisor is deployed as VM on an ESXi host utilizing a digital equipment however guarantee to register NSX supervisor on vSphere vCentre for NSX-v.

Set up VIBs (kernel modules) on ESXi hosts to allow a distributed firewall, routing and VXLAN if utilizing NSX-v. Set up NSX edge as VM on ESXI (for NSX-v). NSX for vSphere makes use of DLR or distributed logical router and centralized routing. Routing kernel module is current on every hypervisor to carry out logical routing between interfaces on distributed routers.

Options of NSX-v

NSX-v affords integration with 3rd occasion companies similar to agentless antivirus, firewalling, intrusion detection and prevention methods, site visitors inspection companies
Kernel degree distributed firewalls

Use case for NSX-v

Safe finish consumer
DMZ wherever
Utility continuity
Catastrophe restoration
Multi information heart pooling
Cross cloud

VMware NSX-T is the following era fashionable VMware NSX information heart resolution. It covers all VMware platforms together with vSphere. The ‘T’ stands for ‘Transformers. It helps you to rework the preliminary use case of community virtualization with NSX-v into the dominion of public cloud and fashionable workloads containerization.

It’s designed for various virtualization platforms and multi-hypervisor environments and will also be used the place NSX-v isn’t possible to deploy. NSX-T helps community virtualization stack for KVM, Docker, Kubernetes and OpenStack in addition to AWS native workloads. It may be deployed with no vCenter server and used throughout heterogeneous computing methods.

NSX supervisor might be deployed as a digital equipment on a KVM host as VMware NSX-T to create a cluster of NSX managers. Kernel modules needs to be put in on KVM hypervisors. There isn’t any risk of set up of edges as digital machines on ESXi in case of NSX-T. Edge set up over the KVM hypervisor isn’t supported.

Options of NSX-T

Scale out networking by federating and administration of quite a few installations of VMware NSX throughout a number of places
Gives full stack networking for contemporary functions
Intuitive dashboard and capabilities

Use circumstances for NSX-T

Micro segmentation
Automation of IT
Developer cloud
Multi-tenant infrastructure

Comparability Desk: NSX-T vs NSX-v

Under desk summarizes the distinction between the 2:

Operate	NSX-T	NSX-v
Pre-requisites (vCenter server dependency)	Doesn’t require vCenter server and allow you to instantly work together with ESXi hosts and onboard them as clear nodes	It’s VMware vSphere resolution solely. Requires connection to vCenter server for integration with ESXi hosts
Overlay Expertise	Makes use of generic community virtualization encapsulation (GENEVE) because the overlay community encapsulation protocol	Makes use of digital extensible LAN (VXLAN) as overlay expertise which creates virtualized community infrastructure
MTU	Minimal 1700 bytes	Minimal 1600 bytes
Routing	Makes use of multi-tier routing structure referred to as TIER-0 and TIER-1 routing topology	Makes use of conventional routing construction
Multi cloud capabilities	True multi cloud platform which permits digital networking capabilities leveraging in each on premises and cloud	Restricted to vSphere environments therefore not thought of a multi cloud platform
Life cycle	NSX-T is successor to NSX-v	Going to be finish of life in 12 months 2022 and prolonged technical steerage will finish in 12 months 2023
Options	It may work with out vCenter, it helps two tier distributed routing, it helps kernel degree distribution firewall and so forth.	It helps ARP suppression, IP deal with scheme configuration is carried out manually, it can’t work with vCenter and so forth.
Hypervisor Assist	VMware ESXi, KVM, Kubernetes, Docker, Public cloud workloads(AWS, Azure, Google), and so forth.	VMware ESXi
NSX Supervisor & Controller	NSX administration can have upto 3 member clusters, with impartial NSX managers to keep away from an outage.	NSX controller deployed as 3-node cluster to a single NSX supervisor (& therefore a single level of failure)
Overlay Switching	Makes use of N-VDS for ESXi and OVS (Open vSwitches) for KVM hosts	Creates logical networks on high of VDS (vSphere Distributed Change)
Kubernetes Assist	Utilizing NCP (NSX Container Plug-in)	No Assist
Supported Environments	Helps multi-cloud, multi-hypervisor & naked steel workloads. It additionally helps cloud native apps	Finest Suited to On-premise workloads
