The Quest Server Virtualization Group just released itslatest Technical Brief titled: Monitoring Physical Storage Beneath the Virtual Infrastructure.
Virtual infrastructures add layers of abstraction that hidekey physical storage performance information. When virtual machines (VMs) orentire virtual infrastructures begin to perform poorly, virtual administratorscan’t see beyond logical datastores to determine if physical storage components(i.e. switches, LUNs, arrays and filers) are actually causing the problem.Conversely, traditional storage administrators can’t see which VMs areoverloading their physical storage devices, making it difficult to properlybalance storage resources across entire virtual infrastructures.
This technical brief covers both the obstacles and proposedsolutions in identifying and resolving storage related issues in virtualizedenvironments quickly and accurately.
