aCeleraWAN Optimization
Array’s award-winning aCelera WAN optimization
controllers help enterprises eliminate network
constraints and accelerate application performance
to provide a LAN-like experience when accessing
applications and data from branch offices, data
centers or the cloud. Array Networks®
pioneered
application-level acceleration and currently leads the
way in cross-platform support for physical and virtual
appliances and software-only WAN optimization.
Combining advanced features for application and
data acceleration with flexible deployment options,
aCelera WAN optimization controllers are future-
proof IT investments that minimize costs and enable
further consolidation of IT operations. 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. Stream-
based 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-to-
use solution for centralized provisioning, drag-and-
drop 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.
The aCelera Advantage
Array aCelera delivers superior acceleration,
the ability to scale seamlessly, flexible hardware
and software options for data center, cloud and
remote environments, comprehensive centralized
management and integration with 3rd party
management systems, end-to-end security and
pricing that is 30-50% less expensive versus rival
solutions – enabling greater ROI in less time.
