You must configure the NAS server so that the HNAS software and HDP software can work together.
Important: No configuration changes are required on the
NAS server to work with
HDP pools.
The high-level process for using HDP pools with a NAS server is as follows:
-
Configure the HDP pools and DP-Vols on the storage:
- Use your storage configurator to create an HDP pool containing sufficient pool volumes to meet your immediate requirements for capacity and performance.
- Using your storage configurator, create DP-Vols on the HDP pool. The total capacity of the DP-Vols should significantly exceed that of the pool volumes in order to fulfil future storage requirements. There should be enough DP-Vols to provide enough queue depth for good performance. As a guideline, DP-Vols usually have a capacity of 8 TiB.
- Place the new DP-Vols into host groups and assign host LUNs to them. Before assigning host LUNs, enable Host Mode Option 7 and 68 on every host group so that the server can detect the new DP-Vols automatically. Alternatively, assign host LUNs to the DP-Vols and then run the server's scsi-refresh command.
-
Use the
HDP-based storage on the
NAS server:
- Allow access to the DP-Vols (SDs) on the NAS server. You can allow access using NAS Manager or the command line interface (see the sd-allow-access command).
-
Create the
NAS server storage pool from the
HDP DP-Vols.
Note: If you plan to create tiered file systems, you must create a tiered storage pool using DP-Vols from two HDP pools.To display a table that relates server device identifiers to DP-Vol internal LUNs, use the sd-list --hdp command. This information is useful when you create the storage pool. See the span-create man page.
- Create the file system on the storage pool.
- Format the file system.
- Mount the file system.
If you are using the command line interface, the filesystem-create -b4 or filesystem-create -b32 syntax can create, format, and mount a file system in a single step. See the Command Line Reference for your system.
