### Attached disk configuration options

Attached disks rely on the Azure Blob storage service. Each standard disk is capable of a theoretical maximum of approximately 500 input/output operations per second (IOPS). Our premium disk offering is preferred for high-performance database workloads and can achieve up to 5000 IOPS per disk. You can use a single disk if that meets your performance needs. However, you can improve the effective IOPS performance if you use multiple attached disks, spread database data across them, and then use Oracle Automatic Storage Management (ASM). For more information, see [The Foundation for Oracle Storage Management](https://www.oracle.com/technetwork/database/index-100339.html). For an example of how to install and configure Oracle ASM on a Linux Azure VM, see [Set up Oracle ASM on an Azure Linux virtual machine](configure-oracle-asm.md).

We recommend placing the VMs in the same availability set to allow Azure to place them into separate fault domains and upgrade domains. If you want to have geo-redundancy, set up the two databases to replicate between two different regions and connect the two instances with a VPN Gateway. To walk through the basic setup procedure on Azure, see [Implement Oracle Data Guard on an Azure Linux virtual machine](configure-oracle-dataguard.md).

With Oracle Data Guard, you can achieve high availability with a primary database in one VM, a secondary (standby) database in another VM, and one-way replication set up between them. The result is read access to the copy of the database. With Oracle GoldenGate, you can configure bi-directional replication between the two databases. To learn how to set up a high-availability solution for your databases using these tools, see [Active Data Guard](https://www.oracle.com/database/technologies/high-availability/dataguard.html) and [GoldenGate](https://docs.oracle.com/goldengate/1212/gg-winux/index.html) documentation at the Oracle website. If you need read-write access to the copy of the database, you can use [Oracle Active Data Guard](https://www.oracle.com/uk/products/database/options/active-data-guard/overview/index.html).

In addition to having a high availability and disaster recovery solution architected in Azure, you should have a backup strategy in place to restore your database. To walk through the basic procedure for establishing a consistent backup, see [Overview of Oracle Applications and solutions on Azure](./oracle-overview.md).
