If you require application acceleration, virtualization, consolidation, cloud computing or disaster recovery, Array aCelera can help.

Stream-Based Differencing

Array’s patent-pending stream-based differencing enables continuous identification and analysis of larger streams of data in sequential order. Streambased differencing facilitates the compression, organization and differencing of all data types as part of an overall data reduction and optimization process. Stream-based differencing efficiently utilizes system capacity to optimally support a large history database that scales along with available resources.

Single Instance Store

Single instance store provides a scalable resource to implement data differencing so that unchanged data is not sent over the network twice. The store also prevents multiple copies of the same data from being stored and maintained and enables predictive preloading based on usage patterns. The history store scales linearly with memory, and storage space adjustments are easy to implement both on physical appliances and in virtual environments.

Single instance store allows aCelera to scale to support the needs of large deployments while maintaining high levels of performance, and is critical to supporting individual users without over-utilizing data stores in the data center or cloud. Single instance store also enables peak performance for complex environments such as meshed networks.

Proxy & Connection Handling

Proxy and connection handling technologies with protocol transparency for CIFS, MAPI, HTTP, HTTPS, RPC-to-NFS and others are lightweight and high performance and are designed to integrate with and take advantage of high-performance appliances and virtualization platforms. Proxy and connection handling is not tied to underlying hardware or operating systems and scalability varies by physical appliance or with the size of CPU and memory in virtual environments.

Forwarding Plane

Forwarding plane is a proprietary technology that allows aCelera to statefully track hundreds of thousands of flows with minimal CPU impact. The forwarding plane also allows for the most flexible deployment and support of network topologies including WCCP, VRRP, PBR and static routing.

Compression

Compression provides an ideal balance between data reduction and maximized throughput by performing compression on the first pass of data and then leveraging application acceleration blueprints to deliver content-aware de-duplication that separates encapsulation from the payload to prevent long-term performance degradation.

Content-Aware De-Duplication

aCelera content-aware de-duplication goes beyond that of other WAN optimization vendors. As data streams are processed, aCelera segments and builds histories and distinguishes the protocol used to transfer the content. By stripping off both TCP/IP and protocol encapsulation, aCelera creates a clean history based on pure content.

Because disk space is not filled with protocol encapsulations that will never be matched in the future, it can be used more effectively to enable better long-term performance; moreover, content that is written cleanly gets better matching. As a result, aCelera delivers better data reduction, faster data transfers and superior matching when content is transferred using different protocols.

TCP Optimization

TCP optimization makes transfers more efficient across wide area networks and enables better utilization of both high and low bandwidth environments, faster recovery after packet loss and bandwidth fairness with other data flows. TCP optimization features include:

Window Scaling – Increases the default 64K TCP window size to ensure efficient throughput in long fat networks

Slow Start with Congestion Avoidance – Determines available bandwidth and avoids sending more data than networks can handle

Fast Convergence – Rapidly increases throughput of each new TCP connection to ensure optimum throughput

Selective Acknowledgement – Precisely determines packets lost during transmission, retransmits only lost packets

Application Blueprints

Legacy application protocols, such as CIFS for file sharing or MAPI for mail, were not designed to run over wide area networks. These protocols break data up into chunks and wait for one chunk to be received before sending another. This is known as chattiness, and chattiness can only be solved by applying application-level intelligence and optimization.

aCelera application blueprints optimize protocols so they operate efficiently across wide area networks. They use techniques such as local acknowledgements of requests, request pipelining, pre-fetching data and combining requests together to significantly accelerate applications. In addition, application blueprints provide application intelligence to the aCelera de-duplication engine to enable content-aware de-duplication.

Traffic Shaping & Secure WAN

Integrated traffic shaping and SSL encryption allow IT to prioritize and secure traffic on the network. Leveraging traffic shaping, guaranteed bandwidth may be assigned to particular hosts, networks, ports or applications. Moreover, by enabling encryption, accelerated traffic can be transmitted over SSL connections to ensure security for traffic sent between aCelera appliances.

aCelera Configuration Management System (CMS)

The aCelera configuration management system enables global configuration and deployment of physical and virtual aCelera appliances. CMS uses templates, so that settings that are common between appliances can be easily managed from one configuration. Changes only need to be made once and will propagate throughout the system, creating simplicity and eliminating errors.

CMS provides IT administrators with an easy-touse solution for centralized provisioning, drag-anddrop configuring, appliance management and a centralized view of entire aCelera deployments.

CMS was designed with the needs of the CIO and IT administrator in mind, optimizing operational efficiency for branch acceleration management and thereby lowering TCO for the enterprise.

aCelera Mobile

aCelera Mobile provides application acceleration using software installed on laptop computers for users who work remotely and independently and mobile users based out of remote offices. aCelera Mobile allows users to benefit from downloads that others in the remote office have already made.

Array’s approach to creating peering relationships between aCelera history stores allows multiple users’ histories to benefit each other, a feature which is a key differentiator between aCelera and competing solutions. Leveraging the same features and capabilities present on aCelera physical and virtual appliances, Array is able to extend industry-leading WAN optimization performance to remote and mobile environments and users.

Flexible Platform Options

aCelera is available as a physical appliance or as a virtual appliance or as software for Windows Server. Deployed as a physical appliance, aCelera is packaged on Array’s high-performance WAN Series hardware to provide the right balance of price, performance and scalability. Deployed as a virtual appliance, aCelera may be installed on industry-leading VMware ESXi hypervisors and may be scaled by increasing CPU cores, memory and disk space. Moreover, aCelera virtual appliances and software can easily be downloaded to remote locations and provisioned dynamically for desired user workloads.

In the data center, aCelera may be deployed on WAN Series hardware or stored on the disks in a SAN and automatically deployed to one or more virtual machines. By deploying the right combination of physical and virtual appliances, IT can achieve the optimal balance of performance, scalability, security, availability and affordability.
