VMware vSAN – les basiques

What Virtual SAN Delivers

Radically Simple Storage

Make your job easier by simplifying storage provisioning and management for vSphere. Deploy storage with just a few mouse clicks from the vSphere Web Client and enjoy native integration with the VMware stack. Virtual machine-centric storage policies automate storage services levels on a per-VM basis.

Advanced Availability and Management

Customers of all industries and sizes trust Virtual SAN to run their business-critical workloads, from key business applications to thousands of virtual desktops. Virtual SAN ensures that data is never lost if a disk, host, network or rack fails and can even tolerate entire site failures with synchronous replication and stretched clusters.

50% Lower TCO

Deploy on inexpensive industry-standard server components to remove large, upfront investments. Eliminate siloed, purpose-built hardware and automate management of storage service levels through VM-centric policies. Further improve TCO with storage efficiency features like deduplication and enhanced automation capabilities.

Exceptional Performance

Built on an optimized I/O data path in the hypervisor and designed for flash speeds, Virtual SAN delivers much better performance than a virtual appliance or external device. Experience up to 100,000 IOPs per host with all-flash and scale up to 64 hosts per cluster—a perfect match for virtual desktops, remote IT and business critical applications.

Enterprise-Ready Storage

Trust your mission-critical applications with the only hypervisor-embedded storage solution. Virtual SAN delivers all-flash performance with up to 100,000 IOPs per host, support for vSphere availability technologies like High Availability (HA), asynchronous replication, stretched cluster capabilities, and storage efficiency features for all-flash including deduplication, compression and erasure coding.

Linearly Scalable Storage

Virtual SAN delivers predictable, elastic and non-disruptive scaling of storage and compute resources, eliminating costly forklift upgrades. Every Virtual SAN cluster can scale out one node at a time or scale up by adding capacity to existing hosts and is capable of achieving over 8 PB of raw storage capacity.


All-Flash Performance

Virtual SAN is the only hyper-converged storage solution delivered directly from the hypervisor, resulting in a flash-optimized architecture that delivers as much as 100,000 IOPS per all-flash node.

Hypervisor-embedded architecture

Leverage the shortest, most efficient I/O data path for optimized performance with the least impact on CPU and memory resources.

All-Flash architecture

Deploy an all-flash architecture with flash-based caching and SSD data persistence to provide up to 100,000 IOPS per host with consistent, low latency.

Server-side caching

Improve virtual machine performance and minimize storage latencies by caching and accelerating read/write disk I/O traffic through enterprise-grade, server-side flash cache.


Automatically rebuild and rebalance storage to align with the storage service levels assigned to each virtual machine in the cluster.

Quality of Service (QoS)

Automatically limits and monitors the IOPS consumed by specific virtual machines, eliminating noisy neighbor issues.

Storage Efficiency

Virtual SAN enables the most cost-efficient all-flash performance by delivering up to 10x greater storage utilization through data reduction technologies to optimize data footprint.

Deduplication and Compression

Optimizes all-flash storage capacity with as much as 7x data reduction while having minimal impact on server CPU and memory resources.

Erasure Coding

Increases usable storage capacity by up to 2x with the same high levels of data resiliency. Tolerate one or two failures with single parity or double parity protection.


Virtual SAN delivers enterprise availability for the most demanding business critical applications, capable of delivering 99.999% uptime and beyond with built-in and tunable failure tolerance settings.

Built-in failure tolerance

Maximize resiliency with built-in distributed RAID, cache mirroring, and per-VM control by specifying how many host, network, disk, or rack failures to tolerate.

Stretched Cluster

Enable enterprise-level availability that ensures no data loss and near zero downtime even in the event of an entire site failure with synchronous replication between two data centers.

Interoperability with the VMware stack

Leverage core vSphere features such as High Availability (HA) and Distributed Resource Scheduler (DRS) along with vSphere snapshots and VMware Site Recovery Manage.

5 Minute RPO with vSphere Replication

vSphere Replication for Virtual SAN provides asynchronous VM replication with RPOs of up to five minutes.


Virtual SAN provides the simplicity of managing storage along with compute and networking in a single, tightly integrated interface–the vSphere Web Client.

Single-pane-of-glass management

Eliminate the need for training on specialized storage interfaces and tools by using vSphere Web Client-based management to provision storage in two clicks.

VM-centric policy-based control and automation

Deploy storage policies with a single click to automatically provision storage resources–no LUNs or RAID configurations necessary.

Health Service

Perform hardware, firmware, and driver compatibility checks directly from the vSphere Web Client, along with real-time diagnostics and reporting on performance and storage capacity.


Virtual SAN is radically simple, enterprise-class software-defined storage powering VMware hyper-converged infrastructure. Get started by learning about Virtual SAN at your own pace or learn with us. We offer a variety of ways to experience the benefits of hyper-converged infrastructure (HCI) and Virtual SAN, from live webinars to self-paced on-demand courses.
