OVERVIEW

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 minimize downtime with rapid provisioning.
  • 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 (in preview), cloud-native applications, and edge appliances through industry standard interface iSCSI protocols. Set consistent service management configurations at the volume group.

  • 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.
  • 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.

  • Gain access to an end-to-end experience like your on-premises SAN and breakthrough innovation with Azure Elastic SAN. See how to easily provision, manage, and scale business-critical workloads on Elastic SAN. Learn in-depth about the performance and storage capacity required to scale terabytes of data cost-effectively.
