Abstract
So far, storage nodes talk to each other only for the DR or backup/archival purposes. In the case of scale-out NAS, there were some proprietary protocols being used along with the dedicated or distributed metadata server. However, the advent of cloud brought a new requirement on the storage where each of the storage nodes need to talk to each other and bring the hot data near the application across datacenters. The communication between the storage nodes should be standard-based to form a global cloud. This topic covers how storage nodes can communicate with each other on the iSCSI standard protocol to form a storage grid and serve the same set of data across multiple datacenters to application instances.
