We developed WOS to support very large volumes of unstructured data with unlimited scalability. Read more…

We developed WOS to support very large volumes of unstructured data with unlimited scalability. WOS delivers the most intelligent capacity for any environment by offering scaling in three dimensions: the total volume of storage, the number of objects and the number of sites. Applications may not have high scalability requirements for all three dimensions initially, but over time those requirements can change due to external elements. To ensure you efficiently grow at every stage, WOS lets you start small and scale without boundaries. With WOS, a fully functional storage could can be deployed with a single node, and then seamlessly scale in all three dimensions by non-disruptively adding nodes, sites and applying or defining new storage management policies.

  • A single federated WOS namespace can be scaled to 32 trillion objects and more than an Exabyte of capacity
  • WOS deployments can start with a single node and seamlessly scale to over 8,000 nodes with predictable scale-out performance
  • WOS is 30% more space efficient than the competing solutions with up to 3.6 Petabytes of storage capacity per rack
  • The number of sites can be seamlessly scaled to meet changing requirements for collaborative workflows, content distribution or disaster recovery
  • With WOS, there are no forklift upgrades—when it's time to add capacity, you can simply add more nodes to the system

THE MOST COST-EFFICIENT DISK STORAGE FOR LARGE VOLUMES OF UNSTRUCTURED DATA

WOS enables even greater efficiencies to give you ultra low TCO. Read more…

To overcome the challenges associated with unstructured data growth, WOS delivers the most cost-effective and efficient approach to managing the long-term storage of massive amounts of data. Designed for comprehensive efficiency across the storage environment, WOS enables organizations to scale their storage infrastructure while maintaining a low TCO.

Optimized CAPEX and OPEX: WOS reduces both CAPEX and OPEX with improved storage efficiency. With 15 to 20% better efficiency than file system based storage (object on Linux or NAS), WOS reduces power usage, floor space, improves network efficiency to preserves LAN and WAN bandwidth (no data rebuild traffic on network) and reduces the amount of storage administration effort (20+PB managed by a single full time employee). The cost savings can be as high as 60% compared to traditional (SAN/NAS) solutions.

Maximum Storage Utilization: At scale WOS, delivers a significantly lower cost per useable TB than file system based storage. WOS enables the customer to utilize a much higher percentage of the systems storage capacity, enabling up to 95% storage utilization with little to no performance degradation. Contrast this against file system based storage (object on Linux or NAS) that typically suffer significant performance lose at maximum utilization levels of just 75%.

Storage Tiering: WOS offers two very distinct levels of storage performance and cost, enabling you to implement a very efficient two-tiered storage strategy. The WOS7000 provides a performance tier while the WOS Capacity appliance provides a 30% lower cost optimized tier. The two-tiered approach allows customers to assign different categories of data to different tiers of storage in order to reduce total storage cost. Using WOS policies and flexible data protection schemes the customer can configure the data protection and storage efficiency based on the storage tier.

WOS Capacity Appliance: The WOS Capacity appliance is a capacity and cost optimized storage solution that maximizes storage capacity with 96 hot-swappable drives and a single single Object Storage Server (OSS) in just five rack-units (5U). Utilizing low cost 8TB SATA SMR drives specifically designed for archiving, the Capacity appliance provides 768TB of raw capacity and support for 8 Billion objects at an industry leading cost per TB.

DESIGNED FROM THE GROUND UP FOR EXTREME EFFICIENCY

WOS has been meticulously designed to easily and reliably store Exabytes of your data in the simplest manner at the lowest cost. Read more…

For organizations concerned about total cost of ownership (TCO), most object storage platforms fall short when delivering comprehensive cost efficiencies for infrastructure, management and bandwidth. Many platforms are cost efficient in at least in one particular configuration, but only for limited use cases and for a very limited range of parameters.

WOS maximizes efficiency for any use case and gives you the most cost efficient infrastructure for mixed workloads of both large and small files. WOS offers the overall best efficiency, including infrastructure cost (raw storage, data center, etc.), management cost (how many people are required to manage the infrastructure) and bandwidth consumption.

True Object Storage Maximizes Efficiency
WOS began as a clean sheet of paper, designed as true object storage to overcome the limitations and of traditional block and file storage systems. WOS is enabled through DDN’s underlying NoFS™, (No File System) a flat single layer, address structure that minimizes read and write operations to disk and enables the system to deliver consistent and predictable performance regardless of object count or storage capacity.

WOS NoFS pure object architecture eliminates all file system overhead and utilizes 99% of disk capacity. The infinitely variable data buckets or “sector” sizes used by NoFS eliminate traditional file system waste and file fragmentation to deliver reliable performance and the highest possible storage utilization at any scale. This delivers the most cost efficient disk storage solution available for large volumes of unstructured data; offering as much as 20% better storage efficiency than object storage systems built on top of Linux file systems.

Self-Healing Architecture: ObjectAssure has self-healing capabilities that reduce the management effort. To prevent silent data corruption ObjectAssure employees a continuous background data scrub that detects and repairs media errors to maintain data durability. In case of a failed drive, ObjectAssure only has to reconstruct the actual data that was lost, as opposed to the entire disk. This dramatically improves data protection by reducing the rebuild window.

Reliable, Secure Global File Management: WOS is the only object storage platform that offers a choice of data protection mechanisms to ensure the highest data durability and availability. WOS Gateways leverage WOS object storage replication policies to provide data protection, disaster recovery and low latency access by applications in multiple, geographically distributed locations to enable a global workflow.

PULSE-POUNDING PERFORMANCE

Explosive throughput and IOPS deliver faster ingest and high-octane application response for mixed-workloads and metadata. Read more…

When it comes to superior performance, you can expect the highest performing object storage from DDN. WOS delivers extreme performance optimization for millions of small files processed per second and up to TB/sec of large file throughput with the lowest network latency. To ensure the most comprehensive set of capabilities, WOS provides the highest performance results for throughput, IOPS and latency. A single WOS Cluster can provide up to 3 million IOPS and 300GB/s throughput (up to 32 clusters can be aggregated for higher performance). Additionally, the flexible data protection options of WOS further enhance overall system performance by conserving network bandwidth, minimizing latency and by providing rapid data recovery.

Optimized For Small and Large Files
Unlike other object storage platforms, WOS is optimized for both large and small objects. Most object storage platforms are not optimized for small objects, so IOPs tends to be neglected in performance conversations. WOS is the only object storage system that is optimized for high-speed throughput of large data volumes and super-fast I/O operations for small files. WOS allows you to mix KB and TB sized objects on a single high performance platform with greater disk efficiency.

Higher Performance for Large Files
Developed for video streaming, content distribution and other large data transfer or high throughput use cases, WOS performance enhancements deliver a significant reduction in latency and time to first byte of data for more predictable quality of service (QoS) for latency-sensitive applications.

The Most Efficient IOPS for Object Storage
With the highest throughput and IOPS, WOS enables faster ingest and application response for today’s mixed workloads and metadata. WOS NoFS is highly efficient with regard to disk I/O, requiring only one I/O per read and two I/Os per write. This model enables WOS to provide very high I/O rates for small files and very high throughput for large files. Large files are segmented and distributed across multiple drives to improve parallelism and throughput.

Increased Performance for File Access Protocols
WOS' cache-first architecture and solid state storage tier enables NAS interface performance to be scaled to meet application demands while providing low-latency global access to data stored in the WOS cloud, regardless of its location.

Latency-Aware Access Manager
WOS optimizes user response time through the use of a latency map to all storage nodes. In large environments with many storage nodes or in distributed environments, when multiple object instances are available WOS automatically retrieves an object from the storage node with the lowest latency.
