Linux网络服务——CentOS7挂载iscsi网络存储
iscsi网络存储简介
iSCSI，即Internet SCSI，是IETF制订的一项标准，用于将SCSI数据块映射为以太网数据包。从根本上说，它是一种基于IP Storage理论的新型存储技术，该技术将存储行业广泛应用的SCSI接口技术与IP网络技术相结合，可以在IP网络上构建SAN。简单地说，iSCSI就是在IP网络上运行SCSI协议的一种网络存储技术
iscsi的组成
- iSCSI IniTIator或者iSCSI HBA iSCSI Target 以太网交换机 一台或者多台服务器
主机规划
| 名称 | IP地址 | 硬件配置 |
|---|---|---|
| iscsi服务端 | 192.168.100.20 | 1核2G |
| iscsi客户端 | 192.168.100.19 | 1核2G |
配置iscsi网络存储挂载
iscsi服务端配置
# 安装iscsi服务端
yum install targetd targetcli -y
# 调用targetcli进行设置
[root@server ~]# targetcli
