![]() A Nexus 1100 can host up to 14 VSMs and it also allows additional services such as a Network Analysis Module to be run. The capabilities and limitations of a VSM running on a Nexus1010 are the same as a VSM running as virtual appliance under ESX. For organisations where there is a very strict boundary between network management and server management, network administrators can avoid the dependency on the VSM running as virtual machine within the ESX cluster. The Virtual Supervisor Module or VSM would normally run as a virtual appliance in an ESX/ESXi cluster but it is possible to run the VSM on dedicated hardware: the Nexus 1010, 1010x and 1100. The configuration of VEMs is done via the VSM NX-OS Command-line interface. VMware KB īesides offering the NX-OS interface to configure, manage and monitor the virtual switch it also supports LACP link aggregation where the standard virtual switches only support static LAGs Therefore Nexus 1000v can no longer be used. The VEM uses the vDS API, which was developed by VMware and Cisco together VMware announced in May 2017, vDS API support will be removed from vSphere 6.5 Update 2 and later. Per infrastructure/cluster you have one VM running the Nexus 1000v as virtual appliance, this is the VSM or Virtual Supervisor Module and then on each node you would have a 'client' or Virtual Ethernet Module (VEM) a vSwitch which replaces the standard vSwitch. The 1000v is a virtual switch for use in virtual environments including both VMware vSphere and Microsoft Hyper-V It is as such not a physical box but a software application that interacts with the hypervisor so you can virtualize the networking environment and be able to configure your system as if all virtual servers have connections to a physical switch and include the capabilities that a switch offers such as multiple VLANs per virtual interface, layer-3 options, security features etc. Nexus 7000 series modular datacenter switches.The Nexus 9000 is the high-end model in the Nexus range of datacenter switches. This platform is optimized for high-density 10 Gigabit Ethernet.Ĭisco Nexus OS Software Defined Networking (SDN) allows the same policies that govern Identity and Access Management (IAM) to dictate levels of access to applications and data through a totally converged infrastructure not possible with legacy network and system access methods. NX-OS has some high-availability features compared to the well-known Cisco IOS. Beside the Nexus 7000 there are also other models in the Nexus range.Īll switches in the Nexus range run the modular NX-OS firmware/operating system on the fabric. ![]() ![]() The first chassis in the Nexus 7000 family is a 10-slot chassis with two supervisor engine slots and eight I/O module slots at the front, as well as five crossbar switch fabric modules at the rear. Cisco Systems introduced the Nexus Series of switches on January 28, 2008. The Cisco Nexus series switches are modular and fixed port network switches designed for the data center.
