Storage Spaces Direct on Intel® Xeon® Scalable Processors

Hello, Claus here again. As you have probably noticed by now, we have a great ongoing collaboration with Intel. In this blog post we are going to look at Windows Server 2016 Storage Spaces Direct on Intel’s latest and greatest hardware, which includes a new processor family, Intel® Xeon® Scalable Processors, an iWARP RDMA network… Read more

To RDMA, or not to RDMA – that is the question

Hello, Claus here again. By now, you have probably seen some of my blogs and demos on Storage Spaces Direct performance. One of Storage Spaces Direct’s advantages is RDMA networking support that lowers latency and reduces CPU consumption. I often get the question “Is RDMA required for Storage Spaces Direct”. The answer to this question… Read more

Storage Spaces Direct with Intel® Optane™ SSD DC P4800X

Hello, Claus here again. Today Intel is announcing the Intel Optane SSD DC P4800X device family, and of course Windows Server 2016 Storage Spaces Direct will support this device. The P4800X device promises better latency and better endurance, so we took these devices for a spin in a Storage Spaces Direct configuration, comparing them to the… Read more

Storage Spaces Direct throughput with iWARP

Hello, Claus here again. It has been a while since I last posted here and a few things have changed since last time. Windows Server has been moved into the Windows and Devices Group, we have moved to a new building with a better café, but a worse view 😊. On a personal note, I… Read more

Deep Dive: The Storage Pool in Storage Spaces Direct

Hi! I’m Cosmos. Follow me on Twitter @cosmosdarwin. Review The storage pool is the collection of physical drives which form the basis of your software-defined storage. Those familiar with Storage Spaces in Windows Server 2012 or 2012R2 will remember that pools took some managing – you had to create and configure them, and then manage… Read more

Storage Spaces Direct with Persistent Memory

Howdy, Claus here again, this time with Dan Lovinger. At our recent Ignite conference we had some very exciting results and experiences to share around Storage Spaces Direct and Windows Server 2016. One of the more exciting ones that you may have missed was an experiment we did on a set of systems built with the… Read more

Squeezing hyper-convergence into the overhead bin, for barely $1,000/server: the story of Project Kepler-47

The Challenge In the Windows Server team, we tend to focus on going big. Our enterprise customers and service providers are increasingly relying on Windows as the foundation of their software-defined datacenters, and needless to say, our hyperscale public cloud Azure does too. Recent big announcements like support for 24 TB of memory per server… Read more

Volume resiliency and efficiency in Storage Spaces Direct

Hello, Claus here again. One of the most important aspects when creating a volume is to choose the resiliency settings. The purpose of resiliency is to provide resiliency in case of failures, such as failed drive or a server failure. It also enables data availability when performing maintenance, such as server hardware replacement or operating… Read more

Deep Dive: Volumes in Storage Spaces Direct

Hi! I’m Cosmos. You can follow me on Twitter @cosmosdarwin. Note: This blog was updated on January 6th 2017 to align more closely to official documention. Quick Review In Storage Spaces Direct, volumes can derive their fault tolerance from mirroring, parity encoding, or mixing the two. Briefly… Mirroring is similar to distributed, software-defined RAID-1. It provides… Read more
