Resiliency on HyperScale X Appliance

HyperScale X platform resilience is a function of system architecture and best practices implemented to deliver the required level of service. On HyperScale X platform, the inherent application level resilience of a distributed deduplication database and index cache is complimented by the scale-out architecture, which uses standard servers with redundant components. Data resilience on HyperScale X platform is based on (4+2) erasure coding, where each block of data is broken into 4 chunks of data and 2 chunks of parity and distributed across the nodes in the pool. The (4+2) erasure coding is the only method used and it provides for tolerance from multiple levels of hardware failure. Implementing industry best-practices such as mirrored root disk and separate subnet/VLAN for public data protection traffic and private storage pool traffic over bonded network interfaces, further enhances resilience at the node-level.
