Network Stack Comparison

  1. SCSI --> SCSI->Physical

  2. FCIP --> SCSI->FC->FCIP-TCP-IP->Ethernet->FCIP->Physical (远程FC SAN环境容灾场景)

  3. FCoE --> SCSI->FE_>FCoE-Ethernet->FCoE->Physical

  4. FC --> SCSI->FC->Physical

FC Protocol Stack

FC Flow Control

  1. BB_Credit

NPV

  1. 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)
  2. 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)
  3. 解决了连接结构中的Domain_ID数量激增问题。

iSCSI Addresses and Name

  1. IQN: iSCSI Qualified Name
  2. EUI: Extended Unique Identifier
  3. NAA: Network Address Authority

  1. 提高吞吐量
  2. 分发流量

延伸VLAN(Stretched VLAN)

  1. A VLAN that spans multiple sites and enables OSI Layer 2 communication between a group of nodes over an OSI Layer 3 WAN infrastructure, independent of their physical location.
