Storageflex WDS WAN Accelerator
Overview
In today’s competitive environment, employees in remote offices need
real-time access to applications and data to stay productive.
Storageflex's WAN Data Services (WDS) Accelerator dramatically
boosts the performance of TCP applications over the wide area
network by up to 100 times, providing remote users with reliable,
real-time access from any location.
The WDS Accelerator lets companies to centralize data and data
management, decreasing remote office IT costs and improving
protection for all enterprise data. The WDS Accelerator also lets
you send more data over existing WAN bandwidth, so that you can
reduce recurring costs and maximize data throughput.
·
Scalable Data Referencing reduces bandwidth consumption up to 95%
·
Application-Specific Optimizations dramatically increase throughput
·
Virtual Window Expansion increases amount of data sent in a single
round
·
High-Speed TCP for blazing fast replication and backup
·
Proxy File Services provide data access even when the WAN goes down

Network Integration and Scalability
·
In-path: Installs transparently in-line and provides automatic
fail-to-wire
·
Out-of-path: “One arm” attachment to routers/ switches with direct
configuration, WCCP, policy based routing, and L4 switch redirection
modes
·
Multi-port Interfaces 4 Port GigE Card available (optional, models
520 and higher). Up to twelve Ethernet ports per WDS appliance
(3010, 3510, 5010) support scalability and redundant WAN router and
switch configurations
·
Asymmetric Routing Connection forwarding for support of incoming and
outgoing route asymmetry
·
Network Topology Full mesh, hub and spoke, and multi-drop topologies
supported
·
Clustering Serial (in-path), Parallel (out-of- path), or Virtual
In-Path clustering for massive scalability
High Availability and
Security
·
Dual watchdog timers ensure no loss in network connectivity in the
event of hardware or software failure
·
N:1 and 1:1 Hot-standby redundancy and N:1 Redundancy clustering for
in-path and out-of- path configurations
·
RAID and dual power and power supplies protect the system from hard
drive or power supply failure
·
Authentication: RADIUS and TACACS+ support for authenticating access
·
Encryption: Configurable IPsec encryption for WDS-to-WDS
communications
·
Scheduled over-the-wire software upgrades with dual image, rollback,
and scheduled restart/ reboot
