A PowerStore host object must be created for each Linux server that has its storage serviced by PowerStore. To simplify defining the logical server objects in PowerStore, create them after completing the following steps:

1. Configure the appropriate hardware for the physical server, and rack and cable the server.

2. Zone the server into the fabric.
3. Power on the database server.
4. On the database server, enable the HBAs in QLogic BIOS.
5. Allow PowerStore to see the enabled HBAs in the server as it interrogates the fabric.

Installing at least two 32 Gb dual-port HBAs in the physical server is recommended. Two dual-port HBAs provide redundancy of initiator ports and HBAs. More HBAs or HBA ports might be necessary to provide the bandwidth necessary to support the expected database I/O performance requirements. When selecting which slots should be used for HBAs, consider which CPU is controlling the slot. Dell Technologies recommends balancing PCIe slots across CPUs to optimize performance.

Perform the following steps to define a host object in PowerStore T models:

1. In PowerStore Manager, select Compute > Hosts Information.

2. Click ADD HOST.

3. In the Add Host wizard, enter the Host Friendly Name and Operating System. Then, click NEXT.

4. Select the Initiator Type that should be used for this host. Then, click NEXT.

5. If NVMe was selected in the previous step, go to step 8. Otherwise, if Fibre Channel was selected, select the host initiators belonging to the physical server and click NEXT.

6. Review the host properties and click ADD HOST.

7. PowerStore Manager displays the newly added host object.

8. If the initiator type was set to NVMe, select the initiator that has an Identifier value matching the database server’s NQN. Then, click NEXT.

9. Review the request to create the host object. If the request is correct, click ADD HOST.

If Oracle RAC is used, repeat this process for each host that belongs to the Oracle cluster.
