Designing a modern VMware availability and disaster recovery strategy often feels like a forced choice between two competing priorities: achieving near-zero downtime or protecting workloads across long geographic distances. VMware Stretched Clusters are exceptionally effective at delivering continuous availability across…
Side‑by‑Side Architectural Comparison Category VMware Stretched Cluster VMware Live Site Recovery (VLSR) Primary Purpose Disaster avoidance through continuous availability Disaster recovery through orchestrated failover and failback Failure Model Survive site failure while workloads continue running Accept outage, then recover workloads…
Use this table to determine whether a stretched cluster is the right architectural choice for a given environment. How to Use This Matrix ✅ Decision Matrix Decision Area Question to Ask Stretched Cluster: YES When… Stretched Cluster: NO When… Business…
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…
