6. After the closed-source KSAL package is installed, perform the following operations as required:
   • If you need to enable the KSAL EC algorithm in Ceph, deploy a Ceph cluster and enable the KSAL EC algorithm based on Compiling and Deploying Ceph.
   • If you need to directly invoke KSAL to optimize system performance, you can skip Compiling and Deploying Ceph and refer to KSAL Development Reference.
