1 PRODUCT BROCHURE WOS OBJECT STORAGE 360 Full Spectrum Object Storage The promise of object storage is simple: to enable organizations to build highly Performance Scalability Reliability Efficiency Security Accessibility reliable, infinitely scalable, cost-efficient storage pools for all their unstructured data needs. But those needs can vary a lot depending on data types, sizes, protection requirements and applications. Think of scale-out web environments where users will store a mix of media files. In these environments, it is very difficult to predict data types and sizes, data locality and consumption patterns. At the other end of the unstructured data spectrum, there are active archive applications where performance and data locality requirements are somewhat less important, but where efficiency and resiliency are critical. WOS is a comprehensive object storage solution, purpose-built, for all your unstructured data needs. WOS offers multiple user configuration settings to make it the ideal solution for applications ranging from web origins and collaborative workflows to content delivery and active archives. DDN has carefully analyzed contemporary storage requirements and delivered a flexible platform that has unprecedented tuning options, that enable users to give priority to the requirements that are most important for their data and applications, in every dimension. WOS is the only object storage platform that offers full flexibility in data protection schemes, delivering performance and durability optimization that complies with all storage requirements. WOS also simplifies deployment including support for a broad set of plug-n-play data access protocols including S3/Swift, NFS/CIFS/SMB and GPFS using embedded or highly scalable discrete gateways. For environments that prefer custom application integration, an embedded REST API is included.

2 FILE STORAGE VS. OBJECT STORAGE Object Storage was designed as a more scalable alternative to file storage solutions for simplified storage needs. File storage was designed for files that need to be modified or changed frequently. As such, file storage is complex to scale because of file system hierarchies and locking mechanisms, which were created to enable file modifications. This overhead drives up the management cost exponentially. FILE VS. OBJECT STORAGE File Storage vs Object Storage DDN is the only storage provider that fully embraces the fact that most unstructured data (80+%) is never modified. The performance, efficiency and scalability of WOS are beyond compare, leading to a TCO that actually decreases per storage unit as the platform is scaled out. WOS stores objects in one scalable namespace. Millions of Files Amendable Data Locking Mechanisms File System Hierarchy Complex to Scale TCO increases exponentially Hundreds of Billions of Objects Immutable Data No Locking Mechanisms One Storage Pool, Object ID s Scales Uniformly Lowest TCO When objects are stored, an identifier is created to locate the object in the namespace. Applications can very quickly retrieve the right data for the users through the object identifier or by querying the metadata information. Figure 1 - File vs. Object WOS FEATURES TRUE OBJECT STORAGE WOS is enabled through DDN s underlying NoFS (no underlying file system) architecture, which minimizes disk operations with as little as a single-disk-operation for reads, and two for writes. (This sharply contrasts with the 8-10 I/O operations that POSIX file systems require, resulting in additional performance and network overhead). Further, the infinitely variable data buckets or sector sizes used in WOS carefully balance performance and platter utilization, while keeping system overhead very low. FEDERATED GLOBAL NAMESPACE WOS Scales out in clusters of up to 256 nodes. Combine up to 32 clusters to build out an Exabyte namespace, distributed geographically. Figure 2 - WOS Features FLEXIBLE DATA PROTECTION An unparalleled choice of data protection schemes allows customers to optimize to higher levels data protection, more cost-effectively. Additional I/O performance or latency optimization is delivered for distributed environments. For archival use cases, Global ObjectAssure TM enables very high data durability and efficiency with the lowest overhead, all without sacrificing self-healing performance.

3 SELF-HEALING ARCHITECTURE ObjectAssure, a unique form of erasure coding, has self-healing capabilities that reduce the management effort. In case of a failed disk, ObjectAssure only reconstructs the actual data that was lost, as opposed to the entire disk. In the event of an object read error, WOS automatically recreates the object from a replica or parity to fulfill the request and then replaces the object to restore compliance with the specified data protection policy. These automatic features dramatically increase data availability and reduce operator intervention. LATENCY-AWARE ACCESS MANAGER METADATA SEARCH WOS avoids scalability bottlenecks by storing metadata in key-value stores, rather than in scale-limiting metadata databases. A highly parallelized backend metadata search allows users to query one or more indexed fields of user-specified metadata across petabytes of objects. MULTIPLE HARDWARE PLATFORM CHOICES WOS is available preinstalled on: DDN high-density, high-performance storage appliance with the option of lower cost archive tier, Node configurations; or on an OCP-ready platform appliance for scale-out web applications. In distributed environments with replicated data, WOS minimizes the access latency for end users. When a user requests an object, WOS automatically retrieves the object from the geographic node with the lowest latency. WOS BENEFITS FLEXIBILITY WOS provides full flexibility to build the right storage infrastructure for any mix of applications. Customers can tune their infrastructure to meet the requirements for their data and application needs. EXABYTE-SCALE Storage platforms can be scaled in three dimensions: the total volume of storage; the number of objects; and the number of sites. It is possible to deploy a fully functional storage cloud with just a single WOS appliance, and then scale seamlessly by nondisruptively adding more nodes. A federated WOS namespace has capacity for up to one exabyte and 32 trillion objects. Figure 3 - Flexible Data Protection EASIER ACCESSIBILITY WOS provides the most complete choice of interfaces, including RESTful APIs and file system gateways from S3/Swift, NFS, CIFS and GPFS to the WOS object store. In addition, interfaces with WOS is offered from third party ISV s and DDN offers a complete WOS Partner development program for users that prefer to do custom integration with their own in-house applications. MORE EFFICIENCY WOS was designed as a single storage solution for all your unstructured data needs, to easily and reliably store petabytes of information at the lowest cost. DDN maximizes storage efficiency through the NoFS architecture, which keeps the solution easy to manage at scale (one infrastructure). Some customers manage up to 20PB with just one full-time employee. The TCO can be further optimized by leveraging the WOS Capacity nodes and ObjectAssure, which provides the highest durability, with the lowest overhead of any object storage solution on the market. COMPLETE RELIABILITY WOS provides full data protection with a wide choice of user-selected protection schemes. Data protection policies can be selected per object: synchronous and asynchronous replication; local ObjectAssure (Erasure Coding); replicated ObjectAssure or Global ObjectAssure (Hierarchical Erasure Coding). This enables customers to design their infrastructure specifically to support their required SLAs. HIGHER PERFORMANCE Storage performance is measured in throughput, IOPS and latency. WOS provides the highest performance results for all three dimensions and multiple clusters can be combined for even higher performance.

4 WOS USE CASES WOS enables customers to build the perfect storage platform for any data type or size. The platform can be tuned to support any application that needs to store and access large volumes of unstructured data. Policies can be set per object, so a single WOS infrastructure can be used to support several applications. For example, it is possible to use WOS for a combined sync and share/disaster recovery/archiving solution at the same time - or to build a scale-out web application that will be generate billions of small files and deliver the high throughput required to stream high-resolution, large movie files. WOS use cases are extended with a mix of in-house developed solutions, integrated applications from third party ISV s and reference architectures through the WOS Partner program. With its rich choice of API s and fi le system gateways, WOS can easily be integrated for Custom Applications as well. WOS currently supports a wide variety of use cases with pre-integrated partner solutions.

WOS ACCESS WOS Access is a family of high performance; high availability gateways that provide multi-protocol S3, NFS/CIFS and GPFS access to DDN s WOS object storage platform. WOS Access gateways provide logical separation of interface overhead and functions from the WOS storage platform enabling interface performance to scale independently of storage capacity to support any performance or capacity requirement. WOS Access gateways can synchronize across multiple, geographically distributed sites to present a single, federated namespace, making them the perfect solution for organizations that require multisite collaboration and/or disaster protection. In distributed collaborative environments, the intelligent location-aware capability assures that users will always access data from the nearest WOS node, providing local LAN level performance. Mission critical applications and collaborative environments require non-stop access to information. WOS Access gateways are also designed to deliver highavailability and provide non-disruptive automatic failover between local gateways, assuring constant access to information in the event of a failure.

6 WOS SPECIFICATIONS It is possible to deploy a fully functional storage cloud with a single WOS system, then scale as needed by adding more nodes, more geographic locations or an archive node tier. A cloud can be created out of any number nodes that have IP connectivity to each other, regardless of their physical location. Storage managers create zones in the WOS cluster, assign nodes in each and create the policies used to manage their cloud storage cluster. The WOS High Performance Appliance node is a four-unit (4U), rack-mountable enclosure that houses two power cooling modules, two controllers, and slots for 60 disks. The controllers provide system management and host connectivity interfaces. The two controllers are redundant and hotswappable modules, which provide intelligence and active/active data protection features.
