Since PowerStoreOS 3.0, native metro volumes have been supported for PowerStore in vSphere Metro Storage Cluster configurations. With the new Virtual Storage Integrator (VSI) 10.0 plug-in for vSphere, you can configure PowerStore metro volumes from vCenter without a single click in PowerStore Manager.
This blog provides a quick overview of how to deploy Dell VSI and how to configure a metro volume with the VSI plug-in in vCenter.
Components of VSI
VSI consists of two components—a VM and a plug-in for vCenter that is deployed when VSI is registered for the vCenter. The VSI 10.0 OVA template is available on Dell Support and is supported with vSphere 6.7 U2 (and later) through 7.0.x for deployments with an embedded PSC.
Deployment
A deployed VSI VM requires 3.7 GB (thin) or 16 GB (thick) space on a datastore and is deployed with 4 vCPUs and 16 GB RAM. The VSI VM must be deployed on a network with access to the vCenter server and PowerStore clusters. During OVA deployment, the import wizard requests information about the network and an IP address for the VM.
When the VM is deployed and started, you can access the plug-in management with https://<VSI-IP>.
Register VSI plug-in in vCenter
A wizard helps you register the plug-in in a vCenter. Registration only requires that you set the VSI Redis Password for the internal database and username/password.
After the VSI VM is configured, it takes some time for the plug-in to appear in vCenter. You might be required to perform a fresh login to the vSphere Client before the Dell VSI entry appears in the navigation pane.
From the Dell VSI dashboard, use the + sign to add both PowerStore clusters used for metro volumes.
Configure a metro volume with the VSI plug-in
As with PowerStore Manager, creating a metro volume with the VSI plug-in requires three steps:
- Create and map a standard volume.
- Configure metro for the newly created volume.
- Map the second metro volume to the hosts.
The following example adds a new metro volume to cluster Non-Uniform, which already has existing metro volumes provisioned in a Non-Uniform host configuration. Esx-a.lab is local to PowerStore-A, and esx-b.lab is local to PowerStore-B.
- Create and map a standard volume in vSphere.
Use the Actions menu either for a single host, a cluster, or even the whole data center in vSphere. In this example, we chose Dell VSI > Create Datastore for the existing cluster Non-Uniform. - Configure metro for the newly created volume.
The VSI Create Datastore wizard leads us through the configuration.- For a metro volume, select the volume type VMFS.
- Provide a name for the new volume.
- Select the storage system.
- For a metro volume, select the volume type VMFS.
In the dialog box, you can expand the individual storage system for more information. We start with PowerStore-A for esx-a.lab.
d. Map the host.
As this is a Non-Uniform cluster configuration, only esx-a.lab is local to PowerStore-A and should be mapped to the new volume on PowerStore-A.
e. Set a Capacity and select other volume settings such as Performance Policy or Protection Policy.
Wizard summary page:
Upon completion, the volume is configured and mapped to the host. The following screenshot shows the new volume, VSI Metro Volume, and the tasks that ran to create and map the volume in vSphere.
For reference, the related jobs in PowerStore Manager for PowerStore-A are also available at Monitoring > Jobs:
f. Select the VSI Metro Volume datastore, and then select Configure > Dell VSI > Storage to see the details for the backing device.
g. On the Storage Details tab under Protection, click Configure Metro.
h. In the Configure Metro Volume dialog box, specify the Remote System and whether host mapping should be performed.
Depending on host registrations on PowerStore, automatic mapping may be unwanted and can be skipped. In this example, PowerStore-B has also the esx-a.lab host registered to provide access to one of the heartbeat volumes required for vSphere HA. The host mapping operation in the Create Datastore wizard creates an unwanted mapping of the volume from PowerStore-B to esx-a.lab. To configure manual mapping after the metro volume is created, select Do not perform the host mapping operation.
The metro volume is immediately configured on PowerStore and the Metro tab in Dell VSI > Storage view shows the status for the metro configuration.
3. Map the second metro volume to the host.
Because we skipped host mapping when we created the metro volume, we must map the esx-b.lab host to the metro volume on PowerStore-B on the Host Mappings tab. Currently, the volume is only mapped from PowerStore-A to esx-a.lab.
a. Select Map Hosts > PowerStore-B to open the Map Hosts dialog box.
b. Map the volume on PowerStore-B for esx-b.lab.
The host mapping overview shows the result and concludes the metro volume configuration with Virtual Storage Integrator (VSI) plugin.
