New Datacenter Network Design Proposal

Sulaiman Syed Profile: Sulaiman Syed

I have mentioned the DC design that was at hand, A new network design was proposed to tackle the issues. Figure below shows the proposed design. The benefits of such design are:

DC network proposal
Image: DC design based on VSS

1-      Virtual Switching System (VSS)

  • With VSS, the two 6500 will become one.
  • This will make both 6500 active in same time, increasing the network bandwidth for all servers and applications.
  • This design will eliminate STP.

2-      User Vlans terminated at MSFC

  • This will reduce the operational and management task. It will keep the network simple, yet the Data Center will be secured by the FWSM.
  • Dynamic routing can be used between the MPLS routing, Core (6500), and future distribution switches that can/should be introduced to follow the standard hierarchy network design.
