REST APIs Virtual Storage Pools with Storage Policies CoprHD Controller Virtual Storage Arrays Traditional (eg. SAN, NAS, AFA) Open Source s/w Standard Servers ISV s/w Standard Servers Block: Automates provisioning; adds block pools to CoprHD Service Catalog; powered by ScaleIO Storage Engine: Writes object-related data (users, metadata and object location) to logical containers of contiguous disk space (128MB) called "chunk" Information is indexed in append-only pattern. Data protection on chunks that are snapped, journaled, and versioned; includes erasure coding; object recovery; HW monitoring; directs I/O to disks. Does not overwrite data, requires locking or invalidates cache. Write requests to same chunk happen simultaneously on different disk sets. Throughput takes advantage of all spindles and NICs. Small object payloads are aggregated in memory. Provides geo protection against site failures; asynchronous replication. A critical aspect of CoprHD's ability to adhere to application-based service requirements is timely awareness of the state of the physical infrastructure, including faults, performance challenges, and degradation, in addition to planned maintenance activities. Intel Rack Scale Architecture management software provides this level of awareness, and through RESTful APIs makes this information available via push and pull queries.

Advancement in technology delivers some concrete benefits before it becomes a trend. With SDS, several business outcomes and drivers, both large and small, makes the technology, a majority success for several enterprises (DellEMC, 2017) (NexentaStor). Cloud-Scale Enterprise Architecture Cloud and other service providers, generally, approach third party leaders, with various proposals, for the transformation of their workloads
