HP StorageWorks Enterprise File Services WAN Accelerator 2.1.3 Release Notes (February 2006)

6
Microsoft Exchange 2003 Turbo
In addition to the acceleration for Exchange 5.5 and 2.0 messaging environments, the HP EFS WAN
Accelerator provides latency-specific optimizations for Microsoft Exchange 2003. The result is dramatically
faster Exchange 2003 e-mail performance.
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.
Job scheduling
Jobs are HP EFS WAN Accelerator command-line interface (CLI) commands that are scheduled to execute
at a time you specify. You can schedule software upgrades in the Management Console or in the CLI; you
must schedule all other jobs using the CLI only. 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 number of short lived connections such as
HyperText Transport Protocol (HTTP).
Faster CIFS folder browsing
Specific areas of CIFS improvement include faster directory browsing operations and better acceleration of
data transfers containing folders of small files.
Throughput performance statistics
Performance statistics measuring application throughput performance are now available in the
Management Console and the CLI.
SNMP enterprise Management Information Base (MIB)
A proprietary HP EFS WAN Accelerator MIB containing detailed device information and statistics is
available for seamless integration into enterprise management systems.
Reporting Improvements
Version 2.1 provides the following performance reporting improvements:
Throughput performance statistics
Performance statistics measuring application throughput performance are now available in the
Management Console and the CLI.
• Throughput statistics
• Per port/application throughput statistics
• View peaks and 95th percentile measurements
• Detailed Connection Statistics
• Byte counts per src/dest for top talkers
• Data reduction per connection
• Application and protocol error status per connection
• View optimization policy per connection
• View current or pre-existing connections
