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…
Previously, I posted about the replication of two HCIs using array-based or vSphere-based replication. This article addresses a third way or an addition to the two previously mentioned options. Dell Recovery Point for VMs (RP4VMs) synchronizes virtual machines to destination…
As I mentioned in the last article, I will write a new article about a disaster-avoidant solution I am deploying where it makes sense. Disaster avoidance in this setting means that we have a platform that is able to absorb…
I work in a manufacturing organization. I design and build systems to support the production of Biologicals that will be injected into patients. Unplanned downtime impacts our ability to deliver products to the market. The biologicals go through maturing phases…
Scenario: Suppose a company called XYZ Corporation heavily relies on virtualization technology for its IT infrastructure. They have many virtual machines running critical applications, and a vCenter Server manages these virtual machines. XYZ Corporation has decided to implement vCenter HA…
In this blog post, we’ll explore what vCLS is, how it works, and the benefits it provides for virtualized environments. What is vSphere Cluster Services? vSphere Cluster Services (vCLS) is a new feature introduced in vSphere 7.0 that provides a…
So we designed, or at least we thought about designing, a VMware Stretched Cluster in the last post. Now we will look into which failure scenarios we have designed a solution to protect us against. Assumptions: For this blog post…
