text: To use an IP-based quorum application as the quorum device for the third site, no Fibre 
  Channel connectivity is used. Java applications are run on hosts at the third site. However, 
  strict requirements on the IP network exist, and some disadvantages with the use of IP 
  quorum applications. 
  
  Unlike quorum disks, all IP quorum applications must be reconfigured and redeployed to 
  hosts when certain aspects of the system configuration change. These aspects include 
  adding or removing a node from the system, or when node service IP addresses are 
  changed. 
  
  For stable quorum resolutions, an IP network must provide the following requirements: 
  
  (cid:2) Connectivity from the hosts to the service IP addresses of all nodes. If IP quorum is 
  
  configured incorrectly, the network must also deal with possible security implications of 
  exposing the service IP addresses because this connectivity can also be used to access 
  the service GUI. 
  
  (cid:2) Port 1260 is used by IP quorum applications to communicate from the hosts to all nodes. 
  
  (cid:2) The maximum round-trip delay must not exceed 80 ms, which means 40 ms in each 
  direction. 
  
  (cid:2) A minimum bandwidth of 2 MBps is ensured for node-to-quorum traffic.
