Virtual combat: One of the network design vswitch

Problem Description:

What kind of vswitch is best for your environment? vsphere Standard Switch (vSS), vsphere distributed switch (VDS) or Cisco Nexus 1000v?

Scenario One:

A small company is expected to deploy ESXi host 5 in a virtual environment, and there is currently no budget to buy software licenses. IT staff has a certain knowledge of VMware, practical experience and need to accumulate.

Recommended programs:

Vsphere Standardswitch (VSS)

The Management plane is used to change the vswitch configuration, and Dataplane is used to specifically transfer packets.

With VSS, each host has its own management plane and Dataplane. There is no interaction between hosts.

Choose the reason:

VSS can save money without having to purchase a Enterpriseplus license. The number of hosts is low and the configuration of small environments is relatively less complex, and the VSS solution based on the ESXi host can meet the requirements

The impact of this design decision:

Because VSS needs to be configured on each ESXi host, it is best to consider using script or VMA to avoid configuration inconsistencies.

Scenario Two:

A company's virtualization design scheme is more complex, ESXi host 20, there will be expansion in the future. Hope to simplify day-to-day maintenance as much as possible, and hopefully maximize the use of virtualized platforms to run critical applications.

Recommended Solutions

ESXi Admin uses VSS, others use VDS

In the case of VDS, the Management plane is implemented by the vcenter focus. This ensures that the changes on the Vswich configuration are centralized and do not need to be set on each host.

Because each host has its own data Plane. This will not affect the transfer of virtual machine packets even when vcenter downtime. affects only management functions.

Choose the reason:

Hybrid scenario: ESXi Management Using VSS, others using VDS

In the case of vcenter downtime, the ESXi can still be managed directly.

Many of the features that are unique to VDS are also available. For example, Pvlan can be easily implemented in the virtual layer of network isolation, without the need for physical network management intervention.

The impact of this design decision:

It is best to consider using host profile,script or VMA to avoid inconsistencies in the VSS configuration.
