text: Hosts that connect to the Storwize V7000 system with iSCSI protocol must be configured 
  correctly, as described in Chapter 3, “Planning” on page 43. 
  
  **Note:**Certain host operating systems can be directly connected to the Storwize V7000 
  system without the need for FC fabric switches. For more information, see this page of the 
  IBM System Storage Interoperation Center (SSIC). 
  
  For load balancing and access redundancy on the host side, the use of a host multipathing 
  driver is required in the following situations: 
  
  (cid:2) Protection from fabric link failures, including port failures on the IBM Spectrum Virtualize 
  system nodes 
  
  (cid:2) Protection from a host HBA failure (if two HBAs are in use) 
  
  (cid:2) Protection from fabric failures if the host is connected through two HBAs to two separate 
  fabrics 
  
  (cid:2) Provide load balancing across the host HBAs 
  
  For more information about various host operating systems and versions that are supported 
  by IBM Storwize V7000, see this page of the IBM System Storage Interoperation Center 
  (SSIC).
