Shared disk database architecture
A shared-disk architecture (SD) is a distributed computing architecture in which the nodes share same disk devices but each node has its own private memory. The disks have active nodes which all share memory in case of any failures. In this architecture the disks are accessible from all the cluster nodes. WebbA shared disk architecture is typically well-suited for large-scale computing that requires ACID compliance. Applications and services that require only limited shared access to data and applications or workloads that are hard to split are usually suitable for a shared disk.
