Integrated Storage functionality allows the cloud admin to build a highly scalable and resilient SAN storage target for virtual server storage using local disks in Compute resources. Using the Integrated Storage, you can create a virtual data store in OnApp Cloud that spans multiple physical drives in Compute resources, with RAID-like replication and striping across drives. The SAN is fully integrated into the Compute resource platform, and the platform is completely decentralized: each node is capable of making decisions about data synchronization and load balancing, and communicates directly with other nodes to move content around dynamically without depending on any centralized controller. There is no single point of failure: for example, if a Compute resource fails, the SAN reorganizes itself and automatically recovers the data. The OnApp Integrated Storage makes exclusive use of CloudBoot to provision Compute resources, so Compute resources must be booted via CloudBoot in order to enable the integrated SAN functionality. For details, refer to the CloudBoot Compute resources section.
