VVOL management is enabled in IBM Storwize V7000 in the System section, as shown in  Figure 5-70. The NTP server must be configured before enabling VVOL management. It is  strongly advised to use the same NTP server for ESXi and for IBM Storwize V7000. Restriction:  You cannot enable VVOLs support until the NTP server is configured in  Storwize V7000. For more information about VVOLs, see the following publications: 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. Chapter 5.
