The AmpliStor Object Storage system is built on a scale-out commodity-based platform. The system is designed to provide high-throughput, high storage density, low power consumption, and low cost of ownership. The system provides the highest levels of durability and availability, through an architecture that has no single points of failure, and provides redundancy over low-cost components. Through the patent-pending BitSpread erasure coding software, the system can tolerate failures of disk-drives, storage modules, controllers, network switches and even site-level failures – without the need to increase storage capacity by a factor of 2-3 X, as is common in other systems. This leverages the low cost platform components to drive the lowest possible TCO.
The system is comprised of three component tiers to enable independent scaling of capacity, bandwidth and performance resources, AmpliStor Controllers and AmpliStor Storage Nodes:
AmpliStor Controllers
AmpliStor Controllers are high-performance, standard Intel ® Xeon® based servers that are pre-packaged with Amplidata’s BitSpread software, MetaStore, and management framework. Controllers provide high-performance access over multiple 10 GbE network interfaces, and can serve data over a variety of network protocols including http/REST object interfaces, and language-specific interfaces such as Microsoft .Net, Python or C. Controllers are equipped with additional 10 GbE ports to interface to the back-end storage pool. Controllers operate in a highly available cluster of Controllers, to provide fully shared access to the storage pool, metadata caching in high-performance SSD’s and protection of metadata. Full specifications are provided in the AmpliStor data sheet.
AmpliStor high-density Storage Nodes: AS20 & AS30
The storage component of the AmpliStor Optimized Object Storage (OOS) system, the AS20 and AS30 Storage Nodes are designed to provide a high-density, power-efficient and cost-effective modular storage. Providing industry-leading storage density with 20 or 30TB capacity in a 1U rack-mount server enclosure. Through the use of a low-power processor, and equipped with ten (10), 2 or 3TB “Green” SATA disk drives, with a maximum power consumption of only 65 Watts (nominal) – 140 Watts (peak), or less than 5 watts per Terabyte. Storage Nodes are connected to the network over redundant Gigabit Ethernet network interfaces. The capacity, density, low-power consumption and overall low TCO of the AmpliStor Storage Node makes it an ideal fit for large, unstructured data applications for Active Media Archives, Online Applications, and Enterprise Big Data Archives. Full specifications are provided in the AmpliStor data sheet.
Integrated Network Fabric
AmpliStor utilizes a dedicated 10GbE / 1GbE redundant Ethernet fabric to interconnect Storage Controllers and Storage Nodes comprising the storage pool. Network fabric components include redundant, high-performance network switches. This enables multiple Gigabytes per second of throughput from a single AmpliStor rack, and scalability of a single system across multiple racks to enable systems that provide tens of Petabytes in a single system, with unified Namespaces and Single System Management views.
