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 […]
In the previous parts we’ve configured our network infrastructure with DCB and set QoS policies to ensure traffic bandwidth. But there is more! In this part I’m going to shown known and unknown tips and tricks that optimizes your network infrastructure.
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 […]
When configuring DCB on Windows Server 2016, you can create policies to tag specific traffic with a specific priority to let DCB handle the right QoS. For more info how this works, please see this blog series: http://www.darrylvanderpeijl.com/windows-server-2016-networking-rdma-dcb-pfc-ets-etc/ When you have multiple types of traffic that you want to separate into DCB priorities, e.g. Storage and […]
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 […]
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 […]
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 […]
With more and more details coming available on Microsoft Azure Stack we can see the direction Microsoft is taking and giving us a peek under the hood of Microsoft Azure itself. Azure Stack will be consistent with Azure and Microsoft is bringing the Azure bits to your datacenter with Azure Stack, we will get the […]
