vSAN for Mixed Workloads: Policy Design and the OSA-to-ESA Transition (opens in new tab)

💡 What is vSAN OSA & ESA? VMware vSAN Original Storage Architecture (OSA) is the legacy disk-group-based architecture designed for mixed magnetic/SSD environments. The newer Express Storage Architecture (ESA) is optimized entirely for high-performance NVMe drives, eliminating disk groups in favor of a single Storage Pool. Enterprise architecture often requires running highly divergent workloads on shared physical infrastructure. Balancing the deterministic latency needed for transactional pro...
