New Features of VMware vSAN 7.0: Simplified Lifecycle Management, Native File Services, and Cloud‑Native Storage Enhancements

VMware recently released vSphere 7.0, and the most interesting part for many is the storage updates. This article focuses on the new capabilities of vSAN 7.0, while other core storage integrations will be covered later.

vSAN is now a fundamental building block of the cloud, deployable in private‑cloud vSphere, VMware Cloud Foundation, and even AWS public cloud.

vSAN 7.0 introduces three main features: a simpler lifecycle management, native file services, and cloud‑native storage enhancements.

The new version lays the foundation for a unified mechanism that updates both software and firmware via the vSphere Lifecycle Manager (vLCM). This unified approach is valuable for SDS vendors, as managing firmware alongside software improves performance and stability.

vSAN now supports a native file system (currently NFS only), eliminating the need for third‑party file services such as Nexenta and simplifying deployments.

Because of the new file service, vSAN can be integrated with Kubernetes via the CSI interface, although block remains the only officially supported protocol at the time of writing.

CSI also supports vVols, snapshots, encryption, and resizing. VMware has partnered with MinIO to provide S3‑compatible object storage, enabling a unified block, file, and object service stack across vSphere, Kubernetes, and MinIO.

Additional enhancements include improved extended‑cluster and two‑node topology management, smarter VM placement, witness‑host failover handling, and intelligent capacity balancing across sites.

Operational and management improvements feature integration of VMware Skyline with vSphere Health and vSAN Health for unified cloud analytics, more detailed VM‑level capacity reporting via UI and API, and clearer visibility of memory usage per host.

The vSAN capacity view now visualizes data replicated by vSphere, and the UI shows per‑host memory consumption for better hardware planning.

Hardware, elasticity, and usage enhancements include support for 32 TB SSDs with improved deduplication, hot‑plug NVMe support, and relaxed requirements for shared disks (no longer requiring Eager Zero Thick), benefiting Oracle RAC deployments.

In summary, vSAN 7.0 delivers simpler lifecycle management, unified block‑and‑file storage, extended data services (Kubernetes integration), and numerous efficiency and operational improvements.

The author notes that while this is not the first overview of vSAN 7.0, it is the first to include a PPT for easier understanding, and promises a future article on vSphere 7.0 core storage enhancements.

The article also mentions a tech preview of vSAN autonomous driving (performance auto‑tuning) that has not yet been released.
