TGT 服务器的优化块设备协议 • NBD • Linux专有块设备协议 • iSCSI • 广泛支持的外部设备协议（块，磁带等）Curve云原生存储支持块设备 • 通过NBD，只支持Linux • 通过SDK API，目前只支持Linux • PFS • 扩大使用范围 • 通过iSCSI支持更多系统，例如Windows, 类UNIX系统等，使用两项基础 技术 • TCP/IP Client端: iscsi initiator，系统自带 • Linux open-iscsi • Windows iSCSI 发起者 • 服务器端 • 必须是CurveBS原生支持的平台，因为需要curve原生接口，目前是LinuxiSCSI target服务器 • LINUX LILO • 一般用于输出内核本地块设备 • TCMU • 作为LILO支持用户态的接口 • 如何评价LILO rve, brpc, c++, protobuf 等) • TCMU多了一层转接，配置过程复杂，业界踩的坑不够多。 • TCMU的用户态代码会受到框架约束，不够灵活。iSCSI target 服务器 • TGT(STGT) • 比较久的历史，原来叫STGT，后来改成TGT • 纯用户态，不与内核绑定 • 支持复杂的存储系统，例如ceph rbd, sheepdog, glfs • 纯C代码，外加一些脚本
