What is a stretched cluster A vSAN stretched cluster is a deployment model where a single vSAN cluster is extended across two geographically separated data centers, with a third site hosting the Witness Appliance. This architecture provides site‑level resilience by synchronously mirroring data between two active…
Storage Policy–Based Management (SPBM) is the backbone of how VMware vSAN delivers predictable, workload‑aligned outcomes. Instead of carving LUNs or managing fixed RAID groups the old-fashioned way, policies define the storage behavior of each VM and each VMDK—granular, dynamic, and…
As virtualization continues to mature and hybrid cloud models become the norm, one architectural principle consistently proves itself essential for both resilience and security: the separation of workload and management. In VMware environments—whether traditional vSphere, VMware Cloud Foundation (VCF), or hybrid…
At VMware Explore, I attempted to take a VCF certification as it was free of charge, so why not? I have no working experience with the product, so it went as expected. I have to study and retry. However, i…
As mentioned in the previous post, I am gathering an overview of vSphere infrastructure in an easy, absorbable format. What other information is good to understand. Output: Fetching vSphere Cluster Information…Cluster Information:Cluster Name: ClusterNameNumber of Hosts: 2DRS Enabled: TrueHA Enabled:…
KPIs, or Key Performance Indicators, in an IT system context are measurable metrics used to evaluate the performance, reliability, and efficiency of the system. These indicators help Key Performance Indicators, or KPIs, are measurable metrics used to assess the performance,…
Some scripts that I use to manage vSphere Turn off SSH if running Count the number of VMs that are in each vSphere cluster List the 10 largest VMs per cluster Per RAM Example output Export to CSV as well…
I wrote the post explaining what Admission control is So, if we have Slot Policy in Admission control active, how do we determine the maximum number of VMs we can run? We can calculate it manually or we can calculate…
