HP StorageWorks Enterprise File Services WAN Accelerator 2.1 Installation and Configuration Guide (November 2005)

16 1 - OVERVIEW OF THE HP EFS WAN ACCELERATOR
 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 end-
point.
 Port Labeling. You can assign a port label to a set of ports when you
define configuration rules in the HP EFS WAN Accelerator. For example,
you can specify a port label for a set of ports when you define fixed-target
rules in the HP EFS WAN Accelerator.
 Backward Compatibility. The HP EFS WAN Accelerator version 2.1
software is backward compatible with version 1.x systems.
 High Speed TCP. For HP EFS WAN Accelerator DL380-5010
configurations, High Speed TCP provides dramatic acceleration and
throughput for high bandwidth networks where the WAN pipe is large
but latency is high.
 Proxy File Service. You can enable Proxy File Service (PFS) support if you
have a Series, 1010, 2010, 3010, or 5010. PFS provides fast access to local
files, accelerated access to files requiring SMB signing, and continuous
access to files in the event of WAN disruption. PFS allows you to store
local copies of files at a remote site (that is, a branch office) in an
integrated virtual file server resident on the HP EFS WAN Accelerator.
PFS requires the HP EFS Remote Copy Utility (HP EFS RCU). For detailed
information, see the HP EFS WAN Accelerator Deployment Guide.
 Microsoft Exchange 2003 Protocol Acceleration. 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. Microsoft Exchange 2003 Protocol Acceleration
dramatically improves Exchange 2003 email performance.
 Network Interface Card Support. The HP EFS WAN Accelerator now
supports multiple HP EFS N4c WAN Accelerator 4-port NIC and Two-
Port Fiber Gigabit-Ethernet Bypass cards. When there are multiple
physical links going from the Local Area Network (LAN) to the WAN you
can use the HP EFS N4c WAN Accelerator 4-port NIC interface to build
multiple pairs of LAN and WAN interfaces (or multiple relays). The Two-
Port Fiber Gigabit-Ethernet Bypass card enables you to connect to fiber
optic devices in your network.
 Microsoft Structured Query Language (MS-SQL) Acceleration Module.
Enabling the MS-SQL Acceleration Module allows you to send SQL
requests and responses between clients and servers to improve
optimization for applications such as Microsoft Project 2003 (MS Project).
This feature is optional. If you want to optimize other applications that
use MS-SQL, contact HP Professional Services at
www.hp.com to assist you in configuring MS-SQL in the HP EFS WAN
Accelerator.
 Improved Common Internet Filing System (CIFS) Performance. Specific
areas of CIFS improvement include faster directory browsing operations
and better acceleration of data transfers containing folders of small files.
