vSAN Max separates the storage layer from compute — purpose-built storage-only nodes serve multiple vSphere clusters over the network. Compute clusters scale for CPU/RAM needs; storage clusters scale for capacity and IOPS needs, independently.
With up to 24 storage nodes and 360 TiB per node, a single vSAN Max cluster reaches 8.6 PB of raw capacity. Erasure coding and compression extend usable capacity further, making it viable for primary storage at data lake scale.
Built on vSAN ESA with NVMe TLC throughout, vSAN Max delivers over 3.6 million IOPS per cluster — enabling consolidated storage for dozens of compute clusters and the most latency-sensitive workloads.
A single vSAN Max storage cluster can be mounted by more than 100 vSphere compute nodes across multiple clusters — providing centralised NVMe storage with HCI simplicity, without the per-host storage overhead of traditional vSAN.
vSAN Max supports stretched clusters across data centres for high availability — synchronous replication between sites with a third-site witness ensures storage survives site-level failures without RPO impact.
November 2025 updates reduced minimum cluster requirements significantly: vSAN-Max-XS nodes now need just 2 NVMe devices and 24 cores, with raw capacity starting from ~80 TB — making vSAN Max accessible for mid-market deployments.
VMware vSAN Max is Broadcom's answer to the limitations of traditional HCI scale — by disaggregating storage from compute, vSAN Max enables organisations to grow each resource tier at its own pace. Instead of adding compute every time storage needs to grow (or vice versa), dedicated vSAN Max storage clusters serve multiple vSphere compute clusters across the network, providing centralised, high-performance, software-defined storage without external SAN hardware.
Built entirely on the vSAN Express Storage Architecture (ESA), vSAN Max inherits all of ESA's efficiency and performance advantages: single-tier NVMe storage, RAID-6 erasure coding at RAID-1 performance, and enhanced compression. Each vSAN Max storage cluster scales to 24 NVMe storage nodes, with each node contributing up to 360 TiB of raw NVMe capacity — reaching 8.6 PB per cluster with over 3.6 million IOPS. The storage cluster is presented to vSphere compute clusters over 25/100 GbE networks, appearing to workloads exactly like locally-attached vSAN storage.
Management remains entirely within vCenter Server — there is no separate management layer for vSAN Max. Storage policies, health monitoring, performance metrics, and capacity planning are all visible in the vSphere UI. vSAN Max is licensed per TiB on a subscription basis, separate from the per-core vSAN entitlement included in VCF or VVF, making it easy to right-size storage investments independently of compute licensing.
Replace multiple SAN arrays with a single vSAN Max cluster — serving all vSphere compute clusters with consistent, policy-driven NVMe storage at lower TCO than traditional storage hardware.
Petabyte-scale NVMe capacity with 3.6M IOPS serves AI training data pipelines — provide compute clusters with low-latency access to datasets without the bandwidth constraints of traditional NAS.
vSAN Max provides the storage backbone for VMware Cloud Foundation private clouds — a single storage cluster serves all VCF workload domains, managed through a unified vCenter console.
When storage capacity runs out but compute is adequate, vSAN Max allows storage-only scale-out — add NVMe storage nodes to the Max cluster without touching compute infrastructure.
