Environment Requirements

This document provides guidance based on the TaiShan server and openEuler OS. Before performing operations, ensure that your software and hardware meet the requirements.

Hardware Requirements

Table 1 lists the hardware specifications.

**Table 1** Hardware requirements
Item	Specification
CPU	Huawei Kunpeng 920 processor
Server	TaiShan 200 server (model 2280)
Server	TaiShan 200 server (model 5280)

OS and Software Requirements

Table 2 lists the OS and software requirements.

**Table 2** OS and software requirements
Item	Version
OS	openEuler 20.03 LTS SP1
OS	openEuler 22.03 LTS SP1
Ceph	14.2.8

As a Huawei-developed closed-source algorithm library, the KSAL is available only for Huawei Kunpeng processors.

Cluster Planning

This document describes how to enable the KSAL EC algorithm in Ceph as an example. A three-node cluster is planned, including three Ceph server nodes and three Ceph client nodes. If you need to directly invoke the KSAL to optimize the system performance, you can plan a cluster based on your requirements.

During Ceph compilation, a server is required for compilation. You can deploy another server outside the cluster or a client node in the cluster as the compilation server.

Figure 1 shows the cluster networking.

Table 3 describes the nodes in the cluster.
