In This Chapter Overview of the HP EFS WAN Accelerator This chapter provides an overview of the HP EFS WAN Accelerator. This chapter includes the following sections: “Overview of the HP EFS WAN Accelerator” next “New Features” on page 15 “Upgrading from Version 1.2 to Version 2.1” on page 17 Overview of the HP EFS WAN Accelerator The HP EFS WAN Accelerator uses Scalable Data Referencing (SDR) and Transaction Prediction (TP) to optimize throughput and save bandwidth in Wide Area Networks (WANs).
Bypass Mode Data Transfer. The HP EFS RCU efficiently transfers data from a client to a specified target directory on a server across the WAN. The HP EFS RCU eliminates extra round-trips caused by Common Internet File System (CIFS), reducing that amount of time it takes to transfer data across the WAN. 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.
If there is a serious problem with the HP EFS WAN Accelerator, it goes into bypass mode to prevent a single point of failure. If the HP EFS WAN Accelerator is in bypass mode, you are notified in the following ways: The Intercept/Bypass status light on the bypass interface is triggered. For detailed information about bypass card status lights, see Appendix A, “Status Lights, Technical Specifications, and Regulatory Information.
16 Serial Cascading. Serial Cascading enables multi-site deployments where server end-points are located at intermediate sites and connections between the client and the server pass through intermediate HP EFS WAN Accelerators to reach their final destination. HP EFS WAN Accelerators direct client-side auto-discovery packets to the correct endpoint. Port Labeling. You can assign a port label to a set of ports when you define configuration rules in the HP EFS WAN Accelerator.
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.
The following upgrade instructions assume that you have a network of 10 HP EFS WAN Accelerators. In this example, you upgrade part of your network, then upgrade the remaining HP EFS WAN Accelerators. To upgrade from 1.2 to 2.1 1. Connect to the Management Console on each HP EFS WAN Accelerator. 2. Install the 2.1 image in the Setup: Software Upgrade page. 3.

In This Chapter Installing and Configuring the HP EFS WAN Accelerator This chapter describes how to install and configure the HP EFS WAN Accelerator.
Choosing a Network Deployment Before you begin the installation and configuration process, select a network deployment: Physical In-Path. In a physical in-path deployment, the HP EFS WAN Accelerator is physically in the direct path between clients and servers. The clients and servers continue to see client and server Internet Protocol (IP) addresses. Physical in-path configurations are suitable for any location where the total bandwidth is within the limits of the installed HP EFS WAN Accelerator.
Figure 2-3. Out-of-Path Deployment Servers LAN Switch HP EFS WAN Accelerator Router Router Switch HP EFS WAN Accelerator Checking Your Inventory Your shipping carton contains the following items: The HP EFS WAN Accelerator—the HP ProLiant DL320-510, DL320-1010, DL320-2010, DL380-3010, or DL380-5010 (depending on your order) One CAT-5E straight-through cable One CAT-5E crossover cable One RS-232 serial null modem cable One or two rack mount power cables (depending on your order).
A standard electronic environment where the ambient temperature is between 10º C and 35º C (50º F and 95º F) and the relative humidity is between 10% and 90% (non-condensing). For detailed information, see Appendix A, “Status Lights, Technical Specifications, and Regulatory Information.” Ethernet connections available within the standard Ethernet limit. Space on a two or four post 19-inch rack. A clean power source dedicated to computer devices and other electronic equipment.
NOTE: The HP EFS WAN Accelerator automatically negotiates duplex settings. If one end of the link is set to auto-negotiate and the other end of the link is not set to autonegotiate, the duplex settings default to half-duplex. This duplex mismatch passes traffic, but it causes late collisions and results in degraded optimization. To achieve maximum optimization set the devices to 100 or full. Mounting the HP EFS WAN Accelerator to a Rack Refer to the instructions that came with your rack kit.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. These requirements apply to the modified work as a whole.
If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission.
[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users.
We call this license the “Lesser” General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances.
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1.
Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4.
You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License.
9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10.
Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and “any later version”, you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14.
