Traditional storage: NFS Local storage	NFS storage requirements for Db2® Requirements for Db2 on SELinux
Elastic File System (EFS) and Elastic Block Store (EBS): On Red Hat® OpenShift Service on AWS (ROSA): Install a Container Storage Interface (CSI) Driver Operator: EFS CSI Driver Operator 4.10. For more information, see AWS Elastic File Service CSI Driver Operator EBS CSI Driver Operator. For more information, see AWS Elastic Block Store CSI Driver Operator. Note: ROSA clusters already have the EBS CSI Driver Operator installed. To add a database instance, see this tutorial on Adding a database instance to an AWS ROSA cluster using the Db2 Operator. On Amazon Elastic Kubernetes Service (EKS): Install a CSI Driver: EFS CSI Driver 1.3.6 +. For more information, see Install the Amazon EFS driver. EBS CSI Driver. For more information, see Amazon EBS CSI driver To add a database instance, see this tutorial on Adding a database instance to an AWS EKS cluster, using the Db2 Operator.	Shared Storage for meta and backup (EFS): Parameters: uid: 0 gid: 0 directoryPerms: "777" provisioningMode: efs-ap fileSystemID: <efs filesystem id> Database Storage, Transactional logs, Temporary TableSpaces (EBS)
On Azure Red Hat OpenShift (RWO): To add a database instance, see this tutorial on Adding a database instance to an Azure Redhat OpenShift (ARO) cluster using the Db2 Operator. On Azure Kubernetes Service (AKS): To add a database instance, see this tutorial Adding a database instance to an Azure AKS cluster using the Db2 Operator. Tip: For clusters hosted on third-party infrastructure, such as IBM Cloud, Amazon Web Services, or Azure, it is recommended that you use storage that is native to the infrastructure or well integrated with the infrastructure, if possible.
