**Table 1** Parameter description
Parameter	Description	Example Value
hostname	Host name	ceph1
nodeid	Node ID	1
ip	IP address of the current node	90.90.26.86
local_ipv4_addr	IP address for communication between the Global Cache client and server	192.168.1.86
public_ipv4_addr	IP address for connecting the Global Cache process to the ZooKeeper cluster	192.168.1.86
cluster_ipv4_addr	IP address for connecting to the BDM of the Global Cache server	192.168.2.86
pt_num	Number of partitions (number of drives x 30)	For a three-node cluster: 180
pg_num	Number of position groups (number of drives x 30)	For a three-node cluster: 180
device:id:0	Drive partition managed by the BDM NOTICE: In the bdm.conf configuration file, path/to/your/disk is the default device managed by the BDM. Change it based on site requirements. Generally, the WAL and DB partitions of Ceph use part of the NVMe space, and you need to manually create the NVMe partition of BDM. In the current version, the Cache Cluster Manager (CCM) must have two partitions. In the current version, ensure that the WCachePool has 200 GB space, the IndexPool has 700 GB space, and the RCachePool uses the remaining space.	nvme0n1p13
device:id:1	Drive partition managed by the BDM	nvme1n1p13
zk_server_on	Specifies whether the current node is used as the ZooKeeper server. 1 indicates yes, and 0 indicates no.	1
ccm_monitor	Specifies whether the current node is used to deploy CCM. 1 indicates yes, and 0 indicates no.	1
