VMware vCenter Server Performance and Best Practices for vSphere 4.1

En till whitepaper som beskriver en del tips och trix.

Fyra huvudområden som tas upp är (lite "svengelska" här också):
- Prestandaförbättringar i vSphere 4.1 jämfört med vSpere 4.0
- vCenter server sizing riktlinjer och mjukvarukrav
- Best Practices för prestanda övervakning, "tuning" och felsökning.
- praktikfall som visar prestandaförbättringar i vSphere 4.1

Hela White pappret hittar man här (är på 46 sidor):  VMware vCenter Server Performance and Best Practices for vSphere 4.1.

Några anteckningar:
Significant performance improvements have been made in vSphere 4.1 compared to vSphere 4.0. The following list highlights some of the most important performance improvements:

  • •Improved performance at higher vCenter Server inventory limits – up to 7 times higher operational throughput and up to 75% reduced operational latency
  • •Improved performance at higher cluster inventory limits – up to 3 times higher operational throughput and up to 60% reduced operational latency
  • •Faster vCenter Server startup – around 5 minutes for maximum vCenter Server inventory size
  • •Better vSphere Client responsiveness, quicker user interaction, and faster user login
  • •Faster host operations and VM operations on standalone hosts – up to 60% reduction in latency
  • •Lower resource usage by vCenter agents by up to 40%
  • •Reduced VM group power-on latency by up to 25%
  • •Faster VM recovery with HA – up to 60% reduction in total recovery time for 1.6 times more VMs
  • •Better load balancing with improved DRS/DPM algorithm effectiveness
