vSphere 7 - Identify vSphere distributed and standard switch capabilities

In VMware vSphere, a switch is a virtual networking device that allows you to connect virtual machines to each other, and to physical network adapters on the host. There are two types of switches in vSphere: standard switches and distributed switches.

vSphere 7 - Describe Datastore Clusters

In Objective 1.6.4 of vSphere’s exam, we must describe datastore clusters. Here, we overview what is datastore cluster and storage DRS. It is critical to identify core Storage DRS features and requirements. Also, it is important to understand DRS initial placement and ongoing balancing and aggressiveness levels.

vSphere 7 - Describe vSphere High Availability

This article focuses on objective 1.6.4 – Describe vSphere High Availability. Here, we overview the concept of vSphere HA and Primary and Secondary hosts. Next, we study vSphere availability settings, including failures and responses in HA, admission control, and heartbeat datastores.

vSphere 7 - Describe How DRS Scores Virtual Machines

This objective needs to describe how Distributed Resource Scheduler (DRS) scores virtual machines. Here, we overview the Old DRS model vs. the new one presented in vSphere 7. Then we study in-depth how VMware DRS scores the virtual machines.

vSphere 7 - Describe vSphere Enhanced vMotion Compatibility (EVC)

In objective, we quickly describe vSphere Enhanced vMotion Compatibility (EVC). First, let’s take a look at VMware vMotion. Then, an overview of how EVC works and some of its basic concepts.

vSphere 7 - Describe Distributed Resource Scheduler (DRS)

In objective 1.6.1, you need to describe Distributed Resource Scheduler (DRS). First, let’s study what DRS is and its key features. Then, let’s take a look at the DRS’ major requirements and key topics: DRS automation and aggression levels, and DRS rules.

vSphere 7 - Describe ESXi Cluster Concepts

Objective 1.6 is a parent of multiple key topics discussing vSphere clustering. Therefore, this article is a quick introduction and an overview of all the essential concepts to understanding ESXi clusters.

vSphere 7 - Describe Instant Clone Architecture And Use Cases

In objective 1.5, you need to describe instant clone architecture and use cases. First, let’s study virtual machine cloning types and techniques, and also compare the critical capabilities of each one. Then we can move to the instant clone topic, study architecture, operation, and use cases. 

vSphere 7 - Differentiate Between vSphere NIOC And vSphere SIOC

There are three ways to manage I/O traffic in vSphere: Network I/O Control (NIOC), Storage I/O Control (SIOC), and Storage Distributed Resources Scheduler (SDRS). This article (Objective 1.4) focuses on how to differentiate between vSphere Network I/O Control (NIOC) and vSphere Storage I/O Control (SIOC). 

vSphere 7 - Describe Basic Storage Concepts In K8s, vSAN, and vVols

The target of objective 1.3.4 is to describe basic storage concepts in K8s, vSAN, and vVols. vVols is critical, and in this objective, we go deep into its concepts, components, and architecture. Here we study key storage concepts of vSphere with K8s, which is now known as vSphere with Tanzu. Finally, we should explore vSAN.

Unable to delete inaccessible datastore

Unable to delete an "inaccessible" datastore

I was switching my storage array, so I migrated the VMs from that old datastore/storage to a new datastore/storage. The old datastore was shared by 3 ESXi hosts, no cluster. After migrating the VMs and unmount/delete the datastore, it was still presented in two of the ESXi hosts and was marked as inaccessible.

Unable to Access the VCSA 6.7 via WinSCP

One of the many and easiest ways to get the logs from the ESXi hosts and vCenter Server Appliance (VCSA), is accessing directly to the files directory using tools such as WinSCP, which helps to transfer the files between a local and a remote computer ( Ex. VCSA). I never have had issues with the ESXi hosts and WinSCP, however, trying to access the VCSA is a different story.
