Installing the Closed-Source KSAL Package

Install KSAL on all nodes in the cluster. KSAL is installed using an RPM package. Decompress the ZIP package to obtain the RPM package and install KSAL.

To obtain the KSAL zstd installation package, refer to Compiling and Installing the KSAL zstd Algorithm Package.

Procedure

Obtain BoostKit-KSAL_1.10.0.zip and save it to the /home directory.
Decompress BoostKit-KSAL_1.10.0.zip in the /home directory.
```
unzip BoostKit-KSAL_1.10.0.zip
```

Install the extracted RPM package.

rpm -ivh /home/libksal-release-1.10.0.oe1.aarch64.rpm

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.
