 ## What is Azure Elastic SAN?
 
-Azure Elastic SAN is a managed, shared block storage service. It provides a central pool of storage capacity and performance, including IOPS and throughput. From this pool, you create multiple volumes and attach them to many compute resources. Instead of provisioning and tuning individual disks for each workload, Elastic SAN allocates storage from a single capacity pool and distributes performance across attached volumes. This approach suits environments with many dynamic workloads where demand changes over time and unused performance from one volume serves other volumes. Elastic SAN is typically used for shared, scalable block storage across many volumes or nodes. It also supports faster volume attach and detach for orchestrated workloads, higher volume density per node, and centralized provisioning and management of storage capacity and performance.

 Expanding the capacity of an Elastic SAN through Azure Container Storage is currently unsupported. You can [resize Elastic SAN](../elastic-san/elastic-san-expand.md) directly from the Azure portal or by using Azure CLI.
