FC Protocol Stack
FC Flow Control
- BB_Credit
NPV
- NPV交换机跟NPIV交换机连接的那个端口叫NP_port（NPIV交换机端口还是F_port）
- 支持NPV的交换机用作直通设备(不需要ID domain，不执行连接结构服务）
- 解决了连接结构中的Domain_ID数量激增问题。
iSCSI Addresses and Name
- IQN: iSCSI Qualified Name
- EUI: Extended Unique Identifier
- NAA: Network Address Authority
Link aggregation
- 提高吞吐量
- 分发流量
