Common Challenges with Unified Storage Systems Today
As Network Attached Storage (NAS) continues to outpace growth expectations, storage vendors often respond to this demand by creating solutions from limited, inefficient architectures. For example, implementing NAS over SAN (which creates performance bottlenecks), providing NAS-only solutions (which creates storage silos), or providing scale-out solutions (which lack the ability to automatically distribute workloads across all nodes).
InfiniBox — A Different Approach
Unlike these solutions, InfiniBox was designed from day one to be a unified storage solution. Its core architecture is based on a data layout and metadata structure that caters to the needs of each protocol type (block and file). This core includes all the data services (snapshots, clones, dual-parity data protection, common data pooling, etc.) that both SAN and NAS need, and use. This allows INFINIDAT to offer a similar feature set on both SAN and NAS, simplifying storage administration and reducing footprint, cost and complexity.
A Modern NAS Architecture
Designing a NAS solution from the ground up to scale to over 2PB requires a lot of attention to performance optimization. With an extremely efficient Btree-based metadata, InfiniBox NAS leapfrogs the large number of indirect metadata reads required to perform a read from disk in large NAS environments. It always points directly to the iNode, reducing read latency to the absolute minimum. Combined with a thick SSD layer to cache data and metadata, InfiniBox NAS offers an ideal combination of cost and performance.
When supporting multiple storage protocols on a single array, it is important to ensure the storage solution has been designed to consider all single points of failure and maximize redundancy and self-healing aspects to surpass the market expectations. Unmatched reliability (99.99999% uptime) is delivered through an innovative self-healing architecture, high performance double-parity RAID, and comprehensive end-to-end data verification capability.
This structure provides a system that delivers no more than 3 seconds of unscheduled downtime per year. In addition, the system is based upon a fully abstracted set of software driven storage functions layered on top of very low cost commodity hardware. The result is a highly available system that supports multiple storage protocols while remaining extremely cost effective.
