红帽全球峰会5.2. 网络通信
Red Hat Ceph Storage 提供两个网络：
- 公共网络，以及
- 一个集群网络。
所有 Ceph 守护进程和 Ceph 客户端都需要访问公共网络，该网络是存储访问安全区的一部分。相反，仅 OSD 守护进程需要访问集群网络（这是 Ceph 集群安全区的一部分）。
Ceph 配置包含 public_network 和 cluster_network 设置。为了强化目的，使用 CIDR 标记指定 IP 地址和子网掩码。如果集群有多个子网，请指定以逗号分隔的 IP/子网掩码条目。
public_network = <public-network/netmask>[,<public-network/netmask>] cluster_network = <cluster-network/netmask>[,<cluster-network/netmask>]
public_network = <public-network/netmask>[,<public-network/netmask>]
cluster_network = <cluster-network/netmask>[,<cluster-network/netmask>]详情请参阅 配置指南的网络配置参考。
