Azure Stack 101: The Definitive Introduction

Featured

Azure Stack

Microsoft’s Azure Stack is an excellent toolset that allows enterprises to run a hybrid cloud right in their own datacenters, giving them additional cloud options.

But to really use it to its best advantage, IT pros should know the ins and outs of Azure Stack so they can use it within their business IT infrastructures to better manage, speed up and control their Azure cloud deployments and workloads.

A good place to start is with a primer on Azure Stack itself to give business users a broad look at what’s under the hood of their IT infrastructure.

Infrastructure: from your Enterprise to the Starship Enterprise: Building the right Playground – Part 1

Now, if you know me or every met me in any way, you know that I am a big Trekkie. The Star Trek series was very defining for my life in my ways. From the original series to Star Trek Next Generation to DS9, Enterprise, and off course Voyager. So recently, I decided to write this blog series in a context that many of us can understand over the coming weeks. I know that Star Trek is the love of many IT Pros.  And so we began this series on infrastructure.. Continue reading

Azure Stack 101: What It Is and How It Can Help Your Datacenter

Microsoft’s Azure Stack allows enterprises to run a hybrid cloud right in their own datacenters, giving them additional cloud options.

Cloud computing continues to expand in use for a wide variety of enterprises, but it all doesn’t have to happen outside your company’s datacenters. Continue reading

Storage Spaces Direct Explained – Applications & Performance

Applications

Microsoft SQL Server product group announced that SQL Server, either virtual or bare metal, is fully supported on Storage Spaces Direct. The Exchange Team did not have a clear endorsement for Exchange on S2D and clearly still prefers that Exchange is deployed on physical servers with local JBODs using Exchange Database Availability Groups or that customers simply move to O365.

Storage Spaces Direct Explained – Management & Operations

Management & Operations
Good day everyone. It been a few weeks, like busy with work and such. Anyways, this post will go into how Management & Operations are done in S2D.  Now, my biggest pet peeve is complex GUI management and yet again, Microsoft doesn’t disappoint.  It still a number of steps in different interfaces to bring up S2D, Check out Aidan Finns blog post on disaggregated management from last year.  It still rings true to this day with the release of 2016. It shouldn’t be this complex IMO 🙁 That being said, let move to the details.

Storage Spaces Direct Explained – Storage QOS & Networking

Storage QOS & NetworkingYo everyone…This is going to be a short blog post in this series. I am just covering Networking and Storage QoS as it pertains to S2D. There are the technologies the bind S2D together.
Storage QoS

S2D is using the Storage (QoS) Quality of Service that ships with Windows Server 2016 which provides standard min/max IOPS and bandwidth control. QoS policy can be applied at the VHD, VM, Groups of VMs, or Tenant Level. Benefits include:

  • Mitigate noisy neighbor issues. By default, Storage QoS ensures that a single virtual machine cannot consume all storage resources and starve other virtual machines of storage bandwidth.
  • Monitor end to end storage performance. As soon as virtual machines stored on a Scale-Out File Server are started, their performance is monitored. Performance details of all running virtual machines and the configuration of the Scale-Out File Server cluster can be viewed from a single location
  • Manage Storage I/O per workload business needs Storage QoS policies define performance minimums and maximums for virtual machines and ensures that they are met. This provides consistent performance to virtual machines, even in dense and overprovisioned environments. If policies cannot be met, alerts are available to track when VMs are out of policy or have invalid policies assigned.

Storage QOS & NetworkingWhat’s New in Networking with S2D?
In Windows Server 2016, they added Remote Direct Memory Access (RDMA) support to the Hyper-V virtual switch.
For those that don’t know what RMDA is it technology that allows direct memory access from one computer to another, bypassing TCP layer, CPU , OS layer and driver layer. Allowing for low latency and high-throughput connections. This is done with hardware transport offloads on network adapters that support RDMA.
Back to Hyper-V virtual switch support for RDMA.  This allows you to configure regular or RDMA enabled vNICs on top of a pair of RDMA capable physical NICs. They also added embedded NIC teaming or Switch Embedded Teaming (SET).
SET is where NIC teaming and the Hyper-V switch is a single entity and can now be used in conjunction with RDMA NICs, wherein Windows 2012 Server you needed to have separate NIC teams for RDMA and Hyper-V Switch.
The images below illustrates the architecture changes between Windows Server 2012 R2 and Windows Server 2016.
