Azure Elastic SAN

Elastic SAN is a cloud-native Storage Area Network (SAN) service built on Azure. Gain access to an end-to-end experience like your on-premises SAN

Experience on-premises SAN capabilities in the cloud

Azure Elastic SAN is a cloud-native service that offers a scalable, cost-effective, high-performance, and comprehensive storage solution for a range of compute options. Get the same simplified management experience in the cloud as with your on-premises storage area network (SAN). Gain higher resiliency and minimise downtime with rapid provisioning.

Scalability up to millions of IOPS (input/output operations per second), double-digit GBps, and single-digit millisecond latencies

Data migration with a single block storage solution that supports the iSCSI remote protocol

Unified storage provisioning and multiple volume management through grouping and policy enforcement just like your on-premises SAN

Management of replication and failover with zone redundant storage (ZRS)

Simplify management across various compute options

Easily provision, manage, and scale workloads on Elastic SAN with the same end-to-end experience and resource hierarchy as on-premises SAN solutions. Extend storage support beyond Azure Virtual Machines to include Azure Kubernetes Service (AKS), Azure VMware Solution (available at a later date), cloud-native applications, and edge appliances through industry standard interface iSCSI protocols. Set consistent service management configurations at the volume group.

Scale performance cost-effectively

Migrate your data to Elastic SAN to achieve the performance of most on-premises SAN environments with the advantages of an efficient cloud-native solution. Deliver millions of IOPS, double-digit GBps throughput, and single-digit millisecond latency to your mission-critical applications. Buy storage capacity and provisioned performance in bulk at a low cost with the flexibility to share the provisioned performance target across multiple volumes.

Minimise downtime and maintain business continuity

Avoid costly downtime with zone redundant storage (ZRS) and local redundant storage (LRS) to protect business-critical data and applications that require high availability. Use ZRS for high levels of resiliency without having to set up multiple deployments of SAN arrays and a replication policy. Get synchronous replication across three zones in a region and safeguard your data in the event of a zone failure.

Comprehensive security and compliance, built in

Control usage and costs with flexible consumption-based pricing

Choose the best combination of base and capacity units for your requirements and optimise price performance. Provision storage capacity and desired performance levels separately. Lower your total cost of ownership (TCO) by purchasing storage capacity and provisioned performance in bulk.
