Q and A: I only have two NICs on my Hyper-V host. Should I team them or not?

Question via e-mail: I am using blade servers for my Hyper-V cluster and I can only have two NICs per blade in this configuration. I am considering two options on how to configure the NICs: 1)      Use one NIC for internal network and one NIC for external network, connected to the virtual switch2)      Team the two NICs together and use the same path for all kinds of traffic What would you recommend? Answer If you're using clusters, I assume you're concerned with high... [Lire la suite]

Everything you want to know about Network Teaming in Windows Server 2012

I was recently given a pointer to the following document: Windows Server 2012 NIC Teaming (LBFO) Deployment and Management It is a very comprehensive guide to setting up network teaming in Windows Server 2012, and discusses many of the common questions that I hear about network teaming (it also discusses network teaming an Hyper-V at length). If you are using (or are planning to use) Hyper-V on Windows Server 2012 in a production environment – you really should read this document, so you understand all the options that are now...

Why can you not use NIC Teaming with iSCSI Binding?

I had an interesting discussion recently with a number of my colleagues around the requirement to place additional uplinks (vmnics) on a virtual switch that are not used by iSCSI binding into the 'Unused' state. One would think that it might be useful to team these uplinks, placing some in Standby mode so that in the case of a failure on the active link, the iSCSI traffic could  move to the standby uplink. But the requirement is that other vmnics must be put into the 'Unused' state and not teamed. Why? This requirement... [Lire la suite]

Activate multi-NIC vMotion in ESXi 5

n vSphere 5 we have support for using multiple Vmkernel ports enabled for vMotion. Having more than one physical network card for vMotion allows us to utilize them simultaneous, even when only transferring a single virtual machine. If having spare NICs we could use up to 16 Gigabit cards and four 10 Gbit NICs just for vMotion. Having 16 extra network ports might not be too common, but the performance increase can be great when just adding another vmnic for the vMotion traffic. --> Please see the rest on the blog...

Using the multiple NICs of your File Server running Windows Server 2008 (and 2008 R2)

1 - Overview When you set up a File Server, there are advantages to configuring multiple Network Interface Cards (NICs). However, there are many options to consider depending on how your network and services are laid out. Since networking (along with storage) is one of the most common bottlenecks in a file server deployment, this is a topic worth investigating. Throughout this blog post, we will look into different configurations for Windows Server 2008 (and 2008 R2) where a file server uses multiple NICs. Next, we’ll... [Lire la suite]
