Definition of Terms

The following terms are used to describe features, attributes, and processes in the HP

EFS WAN Accelerator:

‹Optimization. The process of increasing data throughput and network performance over the WAN using the HP EFS WAN Accelerator. An optimized connection exhibits bandwidth reduction as it traverses the WAN.

‹Scalable Data Referencing (SDR). The proprietary algorithms that allow an arbitrarily large amount of data to be represented by a small number of references to the HP EFS WAN Accelerator data store. As data flows through the HP EFS WAN Accelerator, all TCP traffic is mapped onto references to data that is stored on either side of the link. This technology increases WAN network performance and decreases consumed bandwidth.

‹Auto-discovery. Auto-discovery is the process by which the HP EFS WAN Accelerator automatically intercepts and optimizes traffic on all Internet Protocol (IP) addresses and ports. By default, auto-discovery is applied to all IP addresses and the ports which are not secure or interactive.

‹Fixed-Target. Fixed target rules directly specify out-of-path HP EFS WAN Accelerators near the target server that you want to optimize. You determine which servers you would like the HP EFS WAN Accelerator to optimize (and, optionally, which ports), and add fixed-target rules to specify the network of servers, ports, and out-of-path HP EFS WAN Accelerators to use.

‹Pass-Through. Pass-through describes WAN traffic that traverses the network unoptimized. You define pass-through rules to exclude subnets from optimization. Traffic is also passed through when the HP EFS WAN Accelerator is in bypass mode. Pass-through might be due to in-path rules or because the connection was established before the HP EFS WAN Accelerator was put in place or before the HP EFS WAN Accelerator service was enabled.

‹Bypass. The HP EFS WAN Accelerator is equipped with a bypass interface to prevent a single point of failure. If there is a serious problem with the HP EFS WAN Accelerator or it is not powered on, it goes into bypass mode and the traffic is passed-through unoptimized.

‹Failover. You can deploy redundant HP EFS WAN Accelerators in your network to ensure optimization continues if there is a failure in one of the HP EFS WAN Accelerators. You can enable failover support in the Management Console or you can use the HP EFS WAN Accelerator command-line interface (CLI).

Bypass Mode

The HP EFS WAN Accelerator is equipped with one of the following types of bypass interfaces (depending on your order):

‹HP EFS N2c WAN Accelerator 2-port NIC Card

‹HP EFS N4c WAN Accelerator 4-port NIC Card

‹HP EFS N2f WAN Accelerator 2-port NIC Card
