What's New in vSAN for VMware Cloud Foundation 9.1

VMware Cloud Foundation 9.1 introduces some of the biggest changes to vSAN in years, and in this episode of the Virtually Speaking Podcast, Pete and John sit down with Pete Koehler, Product Marketing Engineer for vSAN, to break it all down.   The conversation dives into how vSAN is becoming simpler to operate, more efficient at scale, and better aligned with modern application and cyber recovery requirements. Pete explains the new Auto RAID capability, the redesigned effective capacity model, enhancements to global deduplication and compression, and how vSAN is reducing operational complexity through more automated, system-managed behavior.   The team also explores native S3-compatible object storage for AI and modern applications, support for QLC drives in cyber recovery environments, improvements for migrations between OSA and ESA clusters, and expanded encryption support across storage clusters.   Topics include: • Auto RAID and simplified storage policy management • Effective capacity and easier capacity planning • Global deduplication and new compression improvements • Zstandard (ZSTD) compression for structured data workloads • Native S3-compatible object storage in vSAN • QLC storage support for cyber recovery use cases • OSA to ESA migration flexibility • Remote datastore enhancements and encryption support • Cyber recovery and disaggregated storage clusters • vSAN security improvements in VCF 9.1 Links Mentioned More Capacity with VMware vSAN Compression and Global Deduplication in VCF 9.1 https://blogs.vmware.com/cloud-foundation/2026/05/07/vsan-compression-and-global-deduplication-in-vcf-9-1/     Cost-Efficient VMware vSAN ReadyNodes Certified for Cyber Recovery Deployments https://blogs.vmware.com/cloud-foundation/2026/05/07/vsan-readynodes-cyber-recovery/     Auto-RAID in VMware vSAN for VCF 9.1 - Comprehensive System-Managed Data Resilience https://blogs.vmware.com/cloud-foundation/2026/05/08/auto-raid-in-vsan-for-vcf-9-1/     Simplifying Storage with the New Effective Capacity View in VMware vSAN for VCF 9.1 https://blogs.vmware.com/cloud-foundation/2026/05/11/effective-capacity-view-in-vsan-for-vcf-9-1/     Greater Flexibility and Security with VMware vSAN Storage Clusters in VCF 9.1 https://blogs.vmware.com/cloud-foundation/2026/05/12/vsan-storage-clusters-in-vcf-9-1/
