5.2.2 vCloud Director Database

Architecting a vCloud Director Solution : Cloud Management Components : 5.2 vCloud Director : 5.2.2 vCloud Director Database

The following are vCloud Director database design considerations:

• Microsoft SQL and Oracle database servers are supported with following high availability options. See the VMware Knowledge Base article Supported high availability options for the vCloud Director database (2037802) (http://kb.vmware.com/kb/2037802).

o Oracle RAC

o Microsoft SQL Failover Cluster

vCloud Director 8.20 additionally supports Microsoft SQL AlwaysOn Availability Groups (https://kb.vmware.com/kb/2148767) in single subnet mode.

• Follow the recommended practices on configuration of the vCloud Director database as specified in the VMware Knowledge Base article, Installing and configuring a vCloud Director 5.1 or 5.5 database (2034540) (http://kb.vmware.com/kb/2034540).

• Collocate the vCloud Director database with vCloud Director cells on the same site to minimize network latency.

• For Microsoft SQL, additional performance improvements can be achieved by changing MS SQL TDS to 1472 (to avoid fragmentation) or to increase it to 8060 while enabling jumbo frames on the vCloud cell – MS SQL network.

• Make sure that the database supports necessary number of connections generated by vCloud Director cells.
