  **IP Quorum**
  Starting with IBM Spectrum Virtualize V7.6, a new feature was introduced for enhanced 
  stretched systems, the IP Quorum application. By using an IP-based quorum application as 
  the quorum device for the third site, no Fibre Channel connectivity is required. Java 
  applications run on hosts at the third site.
