Educational Episodes: Hyperconverged Infrastructure (HCI)

Setting up a failover cluster is a thing that admins must do. To build such cluster, you need to configure shared storage. And, there are a lot of ways to do that. Today, I’d like to discuss how to build a Windows Failover Cluster using a virtual SAN solution (StarWind Virtual SAN) as a shared storage provider.

vSphere 8 now offers the vMotion Application Notification feature, aimed at improving application migrations. Interested in the technical aspects?

Some time ago, I published here comparison of SQL Server Failover Cluster Instances (FCI) and SQL Server Availability Group (AG) performance while having them run on top of StarWind Virtual SAN (https://www.starwindsoftware.com/blog/hyper-v/can-sql-server-failover-cluster-instance-run-twice-fast-sql-server-basic-availability-groups-2-node-cluster-part-2-studying-fci-performance/). Today, I measure SQL Server AG performance on Storage Spaces. The next part sheds light on SQL Server FCI performance on S2D. Can I squeeze two times more TPM out of SQL Server FCI on S2D than SQL Server AG can provide on Storage Spaces?

Whether you’re migrating workloads or fortifying your disaster recovery (DR) strategy, the latest 8.8 release of VMware vSphere Replication has you covered.

It is the second part of my research on SQL Server Availability Groups (AG) and SQL Server Failover Cluster Instances (FCI) performance. Before, I measured SQL Server AG performance on Storage Spaces (https://www.starwindsoftware.com/blog/hyper-v/can-sql-server-failover-cluster-instance-run-s2d-twice-fast-sql-server-availability-groups-storage-spaces-part-1-studying-ag-performance/). Today, I study the performance of SQL Server FCI on S2D, trying to prove that this thing can run 2 times faster than SQL Server AG on Storage Spaces

Thick and Thin VM disks have been around for ages, yet there’s always been some controversy regarding which method is better and whether there’s any performance difference. Discover the key differences and features of Thick and Thin disks, and choose the most optimal space allocation method for your environment.

  Some time ago, I wrote an article about backup storage media. Today, I’d like to talk about secondary storage. Before I move on, I want to clarify what I mean by “secondary storage” here, just to make sure that we are on the same page. Secondary storage is the storage where the actively used data resides. It can be both some local storage like SAN or NAS, or some public cloud hot tier. Well, it’s absolutely true that you can use disk arrays too, but let’s think of them today just as NAS-like servers packed with many disks, ok? That’s entirely up to you “which side you are on”, and there’s no “one-size-fits-all” solution. NAS, SAN, and public cloud storage… Whatever secondary storage you choose, it has own pros and cons. I discuss them in this article.
