HP StorageWorks Enterprise File Services WAN Accelerator 3.0.4 release notes (AG421-96006, March 2007)

HP StorageWorks Enterprise File Services WAN Accelerator 3.0.4 release notes 5
Improved CIFS optimizations
RiOS v3.0 provides additional improvements for a number of Windows file sharing applications and use
cases.
Proxy File Service v3.0
Proxy File Service (PFS) has been updated with RiOS v3.0. PFS provides continuous access to remote file
data during WAN disruptions and provides high speed local file delivery with automated origin server
replication. PFS v3.0 includes improvements in the areas of manageability and scalability. With PFS v3.0
you no longer need to install the HP EFS Remote Copy Utility (EFS RCU) on the Windows server; all the EFS
RCU functionality is embedded in the HP EFS WAN Accelerator, simplifying configuration and
management of PFS shares. PFS is available on the HP ProLiant DL320-520, DL320-1010, DL320-1020,
DL320-2010, DL320-2020, DL380-3010, and DL380-5010 models.
Asymmetric route detection
A prerequisite to HP EFS WAN Accelerators optimizing TCP flows is that all packets for each TCP
connection must pass through the same pair of HP EFS WAN Accelerators. This is a requirement for
packets traveling in both directions across the WAN. However, in asymmetric networks where a client
request traverses a different network link than the server response, the packets traveling in both directions
might not always pass through each HP EFS WAN Accelerator. RiOS v3.0 includes an intelligent scheme
for detecting asymmetric routing environments, reporting when the problem is found, and automatically
passing through traffic for subsequent connections (asymmetric routes may still be removed by using
WCCP). The result is better visibility and interoperability for environments with asymmetric routes.
Client-side connection forwarding
While asymmetric route detection helps identify problems, client-side connection forwarding takes it a step
further by allowing optimization in environments where asymmetric routing occurs on the client-side. In
addition, client-side connection forwarding provides interoperability for environments that use per-packet
load balancing. The combination of server-side and client-side connection forwarding plus asymmetric
route detection streamlines HP EFS WAN Accelerator deployments in the most complex network
environments, while keeping the simplicity of in-path designs.
Netflow export
RiOS v3.0 provides the ability to export real-time flows from an HP EFS WAN Accelerator to a third party
Netflow collector. From the Netflow collector, you can view byte counts by port, per source or destination
IP address, or from a specific interface. You can obtain traffic views for optimized and pass-through traffic
separately or aggregated, and top-talker and listener tallies from a Netflow v5 compatible collector.
New reporting and statistics
RiOS v3.0 provides dramatic improvements in the area of visibility and reporting for device and global
monitoring. Key improvements include:
• Port and application auto-discovery—All TCP traffic flowing through an HP EFS WAN Accelerator is
inspected, and detected ports are automatically added to the management system reporting facility.
Each port is labeled with the name of common applications associated with the ports.
• Pass-through traffic statistics—Port and application byte count statistics are provided for all TCP traffic
that is passed through the HP EFS WAN Accelerator unoptimized. You can view how much and what
type of traffic is optimized versus unoptimized traffic through the HP EFS WAN Accelerator.
• Performance statistics by QoS class—The QoS feature in RiOS v3.0 delivers the ability to view
performance reports by traffic class. Class traffic reporting, including bytes and packets sent versus
bytes and packets dropped, enables you to view how QoS shapes the traffic to enforce configured
policies.
Increase in connection limit
The connection limit has been increased for the following models when running on 3.0 code: HP ProLiant
DL380-3010 (2400 to 3000) and DL380-5010 (4500 to 5000).
