[Azure] Dedicated Hosts

With Azure Dedicated Host, you get the ability to isolate your compliance-related workload VMs, so that capacity isn’t shared to VMs catering to customers. You get a dedicated Hyper-V host that provides control over the mentioned workload separately, allowing to set the maintenance policies of the host. The service comes as a SaaS.

VMware vSAN Cluster Rebalancing: Automatic & Proactive

VMware vSAN clusters are typically aggregates of several ESXi hosts. Local disks with VM data are divided into groups there. It’s preferable that each disk’s load variance doesn’t reach 30%. If it does, there are two options: Automatic and Proactive rebalancing. Each of them has its own pros and cons; you decide which to choose.

Can SQL Server Failover Cluster Instances run on S2D twice as fast as SQL Server Availability Groups on Storage Spaces? Part 2: Studying FCI performance

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

Implement a file server in Azure without using a single VM

It’s usually quite a chore to manage file servers by using VMs. Migrating between file servers in the cloud, enacting replication with DFS-R, and such would require using redundancy mechanisms. All this makes the implementation of file servers in Azure unnecessarily complex. Well, that ship has finally sailed!
