# System Requirements for the IBM FlashSystem Storage Array

Before you configure your storage array, verify that your system meets the following requirements.

## Licenses

Install the following licenses.

Snapshot Type | License
--- | ---
FlashCopy | FlashCopy
Space-efficient FlashCopy | FlashCopy

## Version and Firmware

Install the following software components.

Note

- We recommend that you use certified versions. We do not certify all the minor versions of the firmware, but, if you encounter problems with a minor version during an IntelliSnap operation, we will assist you.

- Starting IBM FlashSystem firmware version 8.6.2.x onwards, IBM has deprecated the use of SMI-S. Hence, if you have upgraded your firmware version to 8.6.2.1 or above, IntelliSnap operations will run using the REST API by default. The lower firmware versions will still use the SMI-S and opening REST API Port 7443 from Client/Proxy to the array is necessary as a prerequisite.

- To enable the creation of Volume Group snapshots, after configuring the IBM FlashSystem Storage Array in the array software, add the volume to the Volume Group.

  Before creating a snapshot, verify that all volumes belong to the Volume Group, as combining Volume Group and Non–Volume Group snapshots in one operation is not supported.

## Ports

- For snap-based operations using REST API support, open port 7443 for both HTTPS and HTTP between the CommServe computer or MediaAgent and the storage array.

- For snap-based operations using SMI-S, open port 5989 for HTTPS and port 5988 for HTTP between the CommServe computer or MediaAgent and the storage array.
