Chunks run on each server node and provide three main services:
Communicates with meta, providing chunk heartbeat information, the node's used capacity, and the replication factor of extents.
Handles read or write requests from clients.
LSM (Local Storage Manager): Manages all local storage disks on this node except the system disk, including PCI-SSD, SSD, SATA, and SAS disks. Local storage disks can be categorized into cache disks and data disks based on their purpose.
Each node's chunk service registers with the meta service (the metadata service), allowing it to manage the entire cluster.
