text: **3.3 Connectivity planning**
  
  IBM Storwize V7000 offers a wide range of connectivity options, both to back-end storage and 
  to hosts. They include Fibre Channel (FC) SAN (8 and 16 Gbps, including direct attachment 
  for some purposes), iSCSI (with 1 Gbps and 10 Gbps ports, depending on hardware 
  configuration), and FCoE connectivity on 10 Gbps ports. 
  
  Storwize V7000 supports SAN routing technologies between Storwize V7000 and storage 
  systems if the routing stays entirely within Fibre Channel connectivity and does not use other 
  transport technologies, such as IP. However, SAN routing technologies (including FCIP links) 
  are supported for connections between the Storwize V7000 and hosts. The use of 
  long-distance FCIP connections might degrade the storage performance for any servers that 
  are attached through this technology. 
  
  Table 3-1 lists the fabric type that can be used for communicating between hosts, nodes, and 
  back-end storage systems. All fabric types can be used at the same time.
