I got this questions two times this week “What is the benifit of VMware Enterprise Plus?” when I was a VMware customer I went Enterprise Plus right away…Lots of people complained however its great value IMO. Perhaps the biggest value of Enterprise plus is just the licensing core count increase from 6 to 12. The current Nahalem EX processors are at 8 cores, and AMD are at 12….Besides this however there are other great features:
- Host Profiles- These are used to automate configurations and ensure compliance; VMware is adding more and more configuration parameters that are included in each release.
- 8 Core SMP virtual machines
- Network I/O Control this is used to QOS virtual network resources
- Storage I/O Control- priortization for VMs resources to shared storage, redistibutes vms un
- Distributed Virtual Switch- Besides trimming down to one switch, and then adding in hosts for consistency a few other benefits…PVLANS, Load Based Teaming, ingress traffic shaping , required for Cisco Nexus 1000v integration
Here is a quick few use cases and review on Pvlans (they were new to me) :
- Communities can communicate with eachother in community and router use case: DMZ with 1 app server and 1 corresponding database server.
- Isolated- Can only communicate with router use case: in a DMZ where you have a standalone webserver that doesn’t have the needs to communicate to other servers in the DMZ as often the case with DMZ; 2nd use case in a desktop vdi enviroment where desktops don’t need to communicate with eachother (This example is from Eric Slueth blog video on Pvlans)
- Promiscous – For routers.
