![]() ![]() The network switch uses VLAN IDs to segregate traffic among the different VLANs operating on the same link. Each VLAN is assigned a distinct VLAN identification (ID). Use VLANs to minimize the number of required physical connections and NICs while concurrently separating traffic. Each VLAN is essentially an independent logical network operating with other VLANs over the same physical connection. ![]() Oracle Database Appliance Virtualized Platform supports multiple VLANs on the same network interface card (NIC) port. On shared disks, virtual machines can start automatically whenever the repository becomes available, can run on a preferred node, and can start or failover to the other node if the preferred node is unavailable. When you use a shared repository hosted on shared disks, the virtual machines consume space in Oracle Automatic Storage Management ( Oracle ASM) disk groups, DATA and RECO. VLANs help you partition network traffic for your virtual machines. Shared repositories provide high-availability options, more storage, and reduce the use of internal storage. To obtain the most flexible shared machine environment, use a shared repository with Virtual Local Area Networks (VLANs). When you create virtual machines in the default repositories, the virtual machines can only run on the node where they are located and therefore have no failover capability. Some of these options require additional network configuration outside of the Oracle Database Appliance servers.īy default you have one local repository on each node and the maximum size is dependent on the hardware:ģ50 GB on Oracle Database Appliance X5-2 Virtualized Platformģ50 GB on Oracle Database Appliance X4-2 Virtualized Platformģ50 GB on Oracle Database Appliance X3-2 Virtualized PlatformĢ50 GB on Oracle Database Appliance Version 1 Based on your requirements, you might provide high-availability options, reduce interference between competing virtual machines for CPU and network access, and provide more storage space and enable automatic startup for virtual machines.
