This section describes:
Storage pools in protection domains are preconfigured at the factory. Each time that you add devices to the system, you must map the devices to storage pools. Additional storage pools can be created both from the CLI and from the UI.
Note: PowerFlex recommends having a minimum of two storage pools in a protection domain.
Volumes are created from storage pools and can be exposed to the hypervisor as a local storage device using the storage data client (SDC). When a volume is configured from a storage pool, it is distributed over all devices residing in that pool. Each volume block has two copies on two different SDSs, enabling the system to maintain data availability following a single point of failure.
Volumes can be:
Dell Technologies recommends using thick provisioning for creating PowerFlex volumes that will be used as datastores for the SAP HANA persistence.
As an administrator, add volumes as follows:
Multiple volumes are created with the same name, but with a different number appended to each volume.
Map PowerFlex volumes to all vSphere servers in the cluster before you create a datastore on the volumes. The PowerFlex SDC on the vSphere server presents the volumes to the ESXi operating system.
To map volumes using the PowerFlex UI:
To create a VMFS datastore on a PowerFlex volume:
Each PowerFlex device is shown as an EMC Fibre Channel Disk followed by an ID number that has eui as a prefix.
The following figure shows the New Datastore page before completion of the create operation:
The datastore that you created is connected to all the vSphere servers in the cluster and is available to all VMs.
