text: **Internal storage**
  Internal storage refers to an array of MDisks and drives that are held in IBM Storwize V7000 
  enclosures. 
  
  **Internet Small Computer System Interface qualified name**
  iSCSI qualified name (IQN) refers to special names that identify both iSCSI initiators and 
  targets. IQN is one of the three name formats that is provided by iSCSI. The IQN format is 
  iqn.<*yyyy*-*mm>*.<*reversed domain name*>. For example, the default for a Storwize V7000 
  canister can be in the following format: 
  
  iqn.1986-03.com.ibm:2076.<*clustername*>.<*nodename*> 
  
  **Internet storage name service**
  The internet storage name service (iSNS) protocol that is used by a host system to manage 
  iSCSI targets and the automated iSCSI discovery, management, and configuration of iSCSI 
  and FC devices. It was defined in Request for Comments (RFC) 4171. 
  
  **Inter-switch link hop**
  An inter-switch link (ISL) is a connection between two switches and counted as one ISL hop. 
  The number of hops is always counted on the shortest route between two N-ports (device 
  connections). In an IBM Storwize V7000 environment, the number of ISL hops is counted on 
  the shortest route between the pair of canister that are farthest apart. The V7000 supports a 
  maximum of three ISL hops.
