I recently posted a converged networks design for Hyper-V on SMB 3.0 storage with RDMA (SMB Direct). Guess what – it was *consultant speak alert* future proofed. Take a look at the design, particularly the rNICs (NICs that support RDMA) in the host(s): There you have 2 non-teamed rNICs. They’re not teamed because RDMA is … Continue reading “A Converged Networks Design For SMB 3.0 Storage & SMB Direct Live Migration”
When you are done reading this post, then see the update that I added for SMB Live Migration on Windows Server 2012 R2 Hyper-V. Unless you’ve been hiding under a rock for the last 18 months, you might know that Windows Server 2012 (WS2012) Hyper-V (and IIS and SQL Server) supports storing content (such as … Continue reading “A Converged Networks Design For Hyper-V On SMB 3.0 Storage With RDMA (SMB Direct)”
Back in January I posted a possible design for implementing iSCSI connectivity for a host and virtual machines using converged networks. In that design (above) a pair of virtual NICs would be used for iSCSI, either in the VM or the management OS of the host. MPIO would “team” the NICs. I was talking with … Continue reading “Another WS2012 Hyper-V Converged Fabric Design With Host & Guest iSCSI Networks”
I’ve done a lot of posts over the last year on converged fabrics in Windows Server 2012 Hyper-V, not to mention nearly 100 pages on the topic in the new Hyper-V book. Pretty much all of them center on using PowerShell to create your converged fabric in the management OS of the host itself. But … Continue reading “Comparing Methods To Implement Converged Fabrics For Windows Server 2012 Hyper-V”
A friend recently asked me a question. He had recently deployed a Windows Server 2012 cluster with converged fabrics. He had limited amounts of NICs that he could install and limited number of switch ports that he could use. His Hyper-V host cluster is using a 10 GbE connected iSCSI SAN. He also wants to … Continue reading “A WS2012 Hyper-V Converged Fabric Design With Host And Guest iSCSI Connections”
Last week I published a script to create a converged fabric clustered host. I wrote that script using the beta of Windows Server 2012 (“8”). But since then, the release candidate has come out. And wouldn’t you know it, some of the PowerShell cmdlets in the RC have changed. Here’s a summary of the changes: … Continue reading “Updated: PowerShell Script To Create A Converged Fabric For Clustered Windows Server 2012 Hyper-V Host”
Here’s a listing of each of my posts from the past 2 weeks on the subject of WS2012 Hyper-V converged fabrics: Windows Server 2012 Hyper-V Making Converged Fabrics Possible Windows Server 2012 Hyper-V & Data Centre Bridging (DCB) Windows Server 2012 Hyper-V & Network Card (NIC) Teaming Windows Server 2012 Hyper-V & The Hyper-V Extensible … Continue reading “All My Windows Server 2012 Hyper-V Converged Fabric Posts From The Past 2 Weeks”
Converged fabrics give us options. There’s no one right way to implement them. Browse around TechNet and you can see that. That means we have options, and options are good. Maybe you don’t like options, so maybe you pick an architecture, script the deployment, and reuse that script for every host configuration. The benefit of … Continue reading “Some Different Converged Fabric Architectures For Windows Server 2012 Hyper-V”
Note: This post was originally written using the Windows Server “8” (aka 2012) Beta. The PowerShell cmdlets have changed in the Release Candidate and this code has been corrected to suit it. After the posts of the last few weeks, I thought I’d share a script that I am using to build a converged fabric … Continue reading “PowerShell Script To Create A Converged Fabric For Clustered Windows Server 2012 Hyper-V Host”
Assuming that you converge all fabrics (including iSCSI and that may require DCB for NICs and physical switches) then my recent work in the lab has found me another reason to like converged fabrics, beyond using fewer NICs. If I am binding roles (parent, live migration, etc) to physical NICs then any host networking configuration … Continue reading “Another Reason To Use Converged Fabrics – Abstract The Host Configuration”
