Here is a snippit:
This appliance really packs a punch. The XML Gateway moves processor-intensive XML tasks from application servers to the network itself. While other vendors rely solely on hardware acceleration cards, like the Tarari XML Accelerator, Vordel leverages its own XML Acceleration Engine (VXA) for XML processing. This approach enables Vordel to offer XML acceleration in both software- and hardware-based appliances.
The hardware-based XML Gateway appliance runs on Vordel's VX Platform, a pre-hardened deployment environment. Essentially, the VX Platform sits atop theDell ( Dell) PowerEdge line of servers and is available in two form factors, depending on processing requirements. The VX platform offers cryptographic acceleration via an nCipher nShield Hardware Security Module (HSM), which applies SSL acceleration to transport-level security. Using redundant power supplies, network interfaces, and RAID-configured disks, the VX Platform eliminates single points of failure and offers high availability out of the box.
Vordel surrounds XML Gateway with a diverse and well-featured toolset. The Vordel Policy Director offers centralized policy creation and management, Vordel Reporter provides visibility and reporting on Web service metrics, and SOAPbox is a testing suite for XML applications. Each of these tools was easy to work with once set up and configured.
