 ## Azure Elastic SAN

Azure Elastic SAN delivers a cost-effective, performant, and reliable block storage solution that connects to a variety of Azure compute services over iSCSI protocol. Elastic SAN enables a seamless transition from an existing SAN storage estate to the cloud without having to refactor customer application architecture. 
+[Azure Elastic SAN](storage-configuration-azure-elastic-san.md) is a network-attached storage offering that provides customers a flexible and scalable solution with the potential to reduce cost through storage consolidation. Azure Elastic SAN delivers a cost-effective, performant, and reliable block storage solution that connects to a variety of Azure compute services over iSCSI protocol. Elastic SAN enables a seamless transition from an existing SAN storage estate to the cloud without having to refactor customer application architecture. 
 
-This solution can scale up to millions of IOPS, double-digit GB/s of throughput, and low single-digit millisecond latencies, with built-in resiliency to minimize downtime. Use Azure Elastic SAN if you need to consolidate storage, work with multiple compute services, or have workloads that require high throughput levels when driving storage over network bandwidth. However, since achieving desired IOPS/throughput for SQL Server workloads often requires overprovisioning capacity, _it's not typically appropriate for single SQL Server workloads_. Combining other low-performance workloads with SQL Server might be necessary to attain the most cost-effective solution. 
-
-When considering VM sizing and performance for Azure Elastic SAN, it's important to understand that storage communication occurs over the network. For example, the VM size E4d_v5 does not support Azure Premium Storage but works well with Azure Elastic SAN as it supports up to 12,500-Mbps network throughput. When using Azure Elastic SAN with this VM size, you must ensure the network and storage throughput requirements for your workload fall under the 12,500-Mbps network throughput limit. 
-
-Determine your network and storage requirements before deploying your SQL Server VM with an Azure Elastic SAN, and then carefully monitor network and storage utilization to confirm the chosen VM can accommodate the workload. To learn more, review [VM performance with Elastic SAN volumes](/azure/storage/elastic-san/elastic-san-performance) and [Elastic SAN metrics](/azure/storage/elastic-san/elastic-san-metrics). 
-
-> [!CAUTION]
-> - VM sizing with Elastic SAN must accommodate production (VM to VM) network throughput requirements in addition to storage throughput. When using Elastic SAN, VM sizes that optimize for IO throughput might not be as cost-effective as VM sizes that optimize for network bandwidth. 
-
-
-Consider placing SQL Server workloads on Elastic SAN for better cost efficiency because: 
-
-- **Storage consolidation and dynamic performance sharing**: Normally for SQL Server on Azure VM workloads, disk storage is provisioned on a per VM basis based on your capacity and peak performance requirements for that VM. This overprovisioned performance is available when needed but the unused performance can't be shared with workloads on other VMs. Elastic SAN, similar to on-premises SAN, allows consolidating storage needs of multiple SQL and non-SQL workloads to achieve better cost efficiency, with the ability to dynamically share provisioned performance across the volumes provisioned to these different workloads based on IO demands. For example, in the East US region, say you have 10 workloads that require 2-TiB capacity and 10K IOPS each, but collectively they don't need more than 60,000 IOPS at any point in time. You can configure an Elastic SAN with 12 base units (1 base unit = $0.08 per GiB/month) that will give you 12 TiB capacity and the needed 60K IOPS, and 8 capacity-only units (1 capacity-only unit = $0.06 per GiB/month), which gives you the remaining 8-TiB capacity at a lower cost. This optimal storage configuration provides better cost efficiency while providing the necessary performance (10K IOPS) to each of these workloads. For more information on Elastic SAN base and capacity-only provisioning units, see [Planning for an Azure Elastic SAN](/azure/storage/elastic-san/elastic-san-planning#storage-and-performance) and for pricing, visit [Azure Elastic SAN - Pricing](https://azure.microsoft.com/pricing/details/elastic-san/).
-- **To drive higher storage throughput**: SQL Server on Azure VM deployments occasionally require overprovisioning a VM due to disk throughput limits for that VM. You can avoid this with Elastic SAN, since you drive higher storage throughput over compute network bandwidth with the iSCSI protocol. For example, a Standard_E32ds_v5 VM is capped at 51,200 IOPS and 865 MBps for disk/storage throughput, but it can achieve up to a maximum of 2,000 MBps network throughput. If the storage throughput requirement for your workload is greater than 865 MBps, you won't have to upgrade the VM to a larger SKU since it can now support up to 2,000 MBps by using Elastic SAN.
+This solution can scale up to millions of IOPS, double-digit GB/s of throughput, and low single-digit millisecond latencies, with built-in resiliency to minimize downtime. Use Azure Elastic SAN if you need to consolidate storage, work with multiple compute services, or have workloads that require high throughput levels when driving storage over network bandwidth. However, since achieving desired IOPS/throughput for SQL Server workloads often requires overprovisioning capacity, _it's not typically appropriate for **single** SQL Server workloads_. To attain the most cost-effective solution with Elastic SAN, consider using it as storage for multiple SQL server workloads, or a combination of SQL Server and other low-performance workloads.
 
+Consider placing SQL Server workloads on Elastic SAN for better cost efficiency, storage consolidation, dynamic performance sharing, and to drive higher storage throughput.
