 Neural Framing. Neural Framing enables the HP EFS WAN Accelerator
to select the optimal packet framing boundaries for SDR. SDR encoding
provides the best optimization results when the largest buffer is available
before a flush is performed.
 Optimization Policies. Setting an optimization policy allows you more
flexibility in applying optimization techniques. For example, if you have a
network with abundant bandwidth, you do not need to perform Lempel-
Ziv (LZ) compression to obtain maximum optimization of data.
 Scheduling Jobs. Jobs are HP EFS WAN Accelerator CLI commands that
are scheduled to execute at a time you specify. You must schedule jobs
using the CLI. You can view pending, inactive, and completed jobs in the
Management Console.
 Connection Pooling. Connection pooling enables you to save an extra
round-trip across the WAN for an initial connection. Connection pooling
is useful for protocols which open a large number of short lived
connections such as Hypertext Transport Protocol (HTTP).
 Automatic Data Store Synchronization. With Automatic Data Store
Synchronization, the HP EFS WAN Accelerator automatically detects
changes in the master HP EFS WAN Accelerator data store and copies the
changes to the backup HP EFS WAN Accelerator data store without
disrupting end users.
 Authentication and Encryption. The HP EFS WAN Accelerator supports
authentication and encryption for communication between two HP EFS
WAN Accelerators using Internet Protocol Security (IPsec). The HP EFS
WAN Accelerator also supports Perfect Forward Secrecy to provide
additional security by renegotiating keys at specified intervals.
 Throughput Performance Statistics. Performance statistics measuring
application throughput are now available in the Management Console
and the CLI.
 SNMP Enterprise Management Information Base (MIB). The
proprietary HP EFS WAN Accelerator MIB monitors device status, peers,
and provides network statistics for seamless integration into network
management systems such as Paessler Router Traffic Grapher (PRTG),
Hewlett Packard OpenView Network Node Manager, and other network
management tools.
Upgrading from Version 1.2 to Version 2.1
The following section describes how to upgrade from Version 1.2 to Version
2.1. Version 2.1 interoperates with 1.2. These instructions assume you are
familiar with the HP EFS WAN Accelerator, the CLI, and the Management
Console.
IMPORTANT: Do not clear the data store before performing a software upgrade.
