for Oracle RAC on GCP
FlashGrid can be deployed in a variety of configurations. Select one that best suits your specific set of HA, performance, capacity, and cost requirements.
Two RAC nodes
The configuration with two database nodes provides tolerance against failure of a single node. Multi-AZ deployment recommended for protection against failure of an entire AZ.
Three RAC nodes
The configuration with three database nodes provides tolerance against simultaneous failure of 2 nodes. Multi-AZ deployment recommended for protection against failure of an entire AZ.
FlashGrid Storage Fabric software turns locally attached disks into shared disks accessible from all nodes in the cluster. The sharing is done at the block level with concurrent access from all nodes.
In 2-node or 3-node clusters each database node has a full copy of user data stored on locally attached Persistent SSD disks or on local SSDs. FlashGrid Read‑Local™ Technology allows serving all read I/O from the locally attached disks and increases both read and write I/O performance. Read requests avoid the extra network hop, thus reducing the latency and the amount of the network traffic. As a result, more network bandwidth is available for the write I/O traffic.
FlashGrid Cloud Area Network™ (CLAN) enables running high-speed clustered applications in public clouds or multi-datacenter environments with the efficiency and control of a Local Area Network.
Network capabilities enabled by FlashGrid CLAN on GCP:
FlashGrid allows you to right-size your cluster at the start and resize later as needed. No need to over-provision in advance for future growth.
