We want to deploy Quest UCA for Skype collection and we would like to know if it is possible to use an external Cassandra database when installing.
Sorry for the late response. When you install UCA, you can select Pilot install or Production install. You can choose to deploy the Storage Engine on a standalone machine.
Please note that, generally, using a NAS/SAN device for the Storage Engine is not supported.
Please Let me know if you have any questions.
