Array Networks aCelera VA
Virtual WAN Optimization Controller

Overview:

aCelera VA Virtual WAN Optimization Controllers accelerate applications, speed data transfers and reduce bandwidth costs using a combination of application, network and protocol optimization.

Array aCelera WAN Accelerators

aCelera

TCP Optimization

aCelera is Array’s core WAN optimization feature set included with every aCelera physical and virtual appliance, as well as aCelera for Windows. TCP optimizations such as window scaling, congestion avoidance, fast convergence and selective acknowledgement promote fairness between data flows, better utilization of high and low bandwidth connections and faster recovery in the event of packet loss.

Stream-Based Differencing

Patent-pending stream-based differencing enables continuous identification and analysis of larger streams of data in sequential order. Stream-based differencing facilitates the compression, organization and differencing of all data types as part of an overall data reduction and optimization process.

Application Blueprints

Application blueprints optimize protocols so they operate efficiently across wide area networks. Using techniques such as local acknowledgement of requests, request pipelining, pre-fetching data and request bundling, blueprints significantly improve application performance. In addition, blueprints provide the application intelligence required for content-aware de-duplication.

Content-Aware-De-Duplication

Strips off TCP/IP and protocol encapsulation to create a clean history that results in better data reduction, faster data transfers and superior matching for content transferred using different protocols.

Single Instance Store

aCelera’s unique single instance store provides a scalable resource to implement data differencing such that unchanged data is not sent over the network twice. In addition, the store scales linearly with available memory and enables predictive preloading based on usage patterns.

Compression & Traffic Shaping

Compresses the first pass of data, and then uses application blueprints to perform content-aware de-duplication and prevent long-term performance degradation. For business-critical applications, traffic shaping may be used to assign guaranteed bandwidth to particular hosts, networks, ports or applications.

aCelera CMS

aCelera Configuration Management System

With aCelera CMS, administrators gain a single console from which to view and manage all aCelera WAN accelerator deployments. aCelera CMS may be used with a few instances or with thousands of appliances and provides enormous benefits in streamlining management tasks.

CMS allows policies to be managed at global level rather than device by device, and allows aCelera to be deployed anywhere in the world in less than thirty minutes. In addition, CMS simplifies change management and keeps a central backup of device configurations to ensure business continuity.
