VMware NSX -- More Than Just Hype
Pros
- Broadcast Suppression: By suppressing broadcast traffic, we have been able to deploy a single VDI network in a /18 network space, allowing for rapid growth and proper DHCP lease timing for a VDI instant clone environment.
- Networking HA: Leveraging internal mechanisms for high availability, it provides disaster resiliency to a virtual networking environment.
- Cost Savings: All available features of NSX are licensed simultaneously. Load balancers, firewalls, and routers are all licensed as features, not per object, allowing for the deployment of as many of these objects as are needed.
Cons
- Firewall rules can break all communication. If a rule is improperly written, it can block all communication to the hosts, vCenter(s), and NSX components, requiring lengthy recovery times.
- If NSX components break, it can break the entire system if it is not properly designed. No components are required to manage NSX which should exist behind NSX networks, just like no vCenter components should exist behind vCenter objects (VVols, VSAN, DVS).
Return on Investment
- Increased security.
- Increased agility.
- Increased flexibility.
