HP StorageWorks Enterprise File Services WAN Accelerator 2.1.5 Release Notes (392363-004, June 2006)

HP StorageWorks Enterprise File Services WAN Accelerator 2.1.5 release notes 7
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
• Apply TCP keep-alive or reset to a specified connection
• Connection Count Trending
• Data Store Hit Rates and Disk Space Used
• 3D Rendition of Traffic Patterns
• Five Minute Trending Interval
• Improved Traffic Summary Statistics
Limitations
• Samba SMB client on Linux with either a Windows or Samba server gains only bandwidth
optimization, not latency optimization.
• An SMB mount from Linux to any CIFS server is not significantly accelerated. (It performs Scalable Data
Referencing but does not perform Transaction Prediction.)
• CIFS performance degradation occurs with multiple sets (pairs) of in-path HP EFS WAN Accelerators
(Bug #3746).
For example:
client->DL320-2010->WAN->DL320-2010->DL320-1010->DL320-2010->server
This problem is dependent on this configuration. Contact HP Technical Support for further information at
