Consolidating servers vmware
Once enabled it dramatically improves 10 Gb E performance, achieving close to 9.7 Gb of throughput.
It is unlikely that you will use one 10 Gb E network card per VM in the host; most likely, you will use one for the whole environment and then a redundant card for failover.Download our latest guide to the top strategies solution providers can leverage for starting up and securing a cloud practice, successful approaches to selling and marketing cloud, and why it is urgent for partners to transition now.The whole point of a VMware server virtualization project is to consolidate server resources, thereby saving your customers money.Slots will need to be allocated for storage I/O as well.This means that the number of slots available to you is the gating factor in the amount of VMs you can create -- not the amount of CPU or I/O resources at your disposal.But as your customers' server virtualization projects mature, you may begin to look at their unvirtualized servers and wonder if there is a way to integrate them into the virtualized environment.
The I/O performance problems, however, present a real obstacle -- high network bandwidth is a serious issue.
When using Net Queue, each VM is assigned to a virtual NIC, and each virtual NIC has its own queue, eliminating the bottleneck.
This allows you to subdivide the 10 Gb E card on a per-VM basis, delivering near-maximum throughput.
In fact, at VMworld in September, a test on a standard 10 Gb E card with standard queuing achieved only about 4 Gb of total throughput.
Better queuing in high-bandwidth environments To address limitations in its standard queuing mechanism, VMware introduced Net Queue.
But a new feature in VMware ESX Server 3.5, Net Queue, will help you virtualize those high-bandwidth servers so your customers get more oomph from server virtualization.
