I never really do opinion posts, but when I started writing this.. text just kept coming.. enjoy 🙂 So the word is officially out. Windows Server Software-Defined (WSSD) is going to be rebranded to Azure Stack HCI for Windows Server 2019. When I first heard about it I was, probably just like you, surprised and […]

Two-way mirror vs Nested resiliency
In this blogpost I’m testing out the new resiliency method which we can use with 2-node clusters in Windows Server 2019. This blog is not meant as performance showcase for the hardware but to show the differences between a regular Two-way mirror and nested resiliency volume. Why do I want nested resiliency? Nested resiliency helps […]
Storage Spaces Direct – Cache Disk Status
Storage Spaces Direct can make use of cache disks if you have provided SSDs or NVMe SSDs in your nodes. Normally the capacity disks are bound to cache disks round-robin, see the official Microsoft doc here. If you suspect or see that one node is not getting the right performance numbers you might wonder if […]
Windows Server 2016 Networking – Part 1- RDMA, DCB, PFC, ETS, etc
In this multi-part blog series I’m going to try to clear some fog around the networking parts needed in Windows Server 2016, especially when using Storage Spaces (Direct). I’ll be touching multiple areas, things that were new to me (I’m not a network guy) such as DCB and and PFC, but also recommendations on the […]
Storage Spaces Direct Needs Rebalance
When you write or delete a lot of data in your storage pool it could be that your volumes end up with the operational status of “Needs Rebalance” This operation needs to be executed by the Administrator (Yes, i’m pointing at you right now) when your disks need a rebalance. You can use the following […]
No disks with supported bus types found to be used for S2D
I had some HP DL380’s to test Storage Spaces Direct (S2D) and walked into the following error: Enable-ClusterStorageSpacesDirect : No disks with supported bus types found to be used for S2D At line:1 char:1 + Enable-ClusterStorageSpacesDirect + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : ObjectNotFound: (MSCluster_StorageSpacesDirect:root/MSCLUSTER/…ageSpacesDirec t) [Enable-ClusterStorageSpacesDirect], CimException […]
Resize Storage Spaces Direct Volume
In this blog post I will show you how to resize a Storage Space AKA virtual disk based on Storage Spaces Direct. The first thing is to understand that Multi-Resilient volumes are created differently comparing to a Parity or Mirror volume. A Multi-Resilient volume makes use of two tiers instead of one and therefore when expanding […]
