WHAT IS A CISCO SWITCH SERIES
The 2000 series consists of 4 different models. In combination with the 5000/6000/7000 mother-switch you can create a so-called Distributed Modular System. The interconnection between this 'remote line card' and the 5000 or 7000 parent switch uses either proprietary interfaces (CX-1 for copper or the short or long range Cisco Fabric Extender Transceiver (FET) interfaces), or standard interfaces (Cisco SFP+ SR and LR fibre interface modules or SFP+ Twinax cables). The Nexus 2000 series are fabric extenders (FEX): 'top of rack' 1 U high system that can be used in combination with higher end Nexus switches like the 5000, 6000 or 7000 series: the 2000 series is not a 'stand-alone' switch but needs to be connected to a parent and should be seen as a 'module' or 'remote line card' but then installed in a 19" rack instead of in a main switch-enclosure. 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.
WHAT IS A CISCO SWITCH UPDATE
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.
WHAT IS A CISCO SWITCH SOFTWARE
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.

The Nexus 9000 is the high-end model in the Nexus range of datacenter switches. Cisco 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.
