HP StorageWorks Enterprise File Services WAN Accelerator 3.0.4 Command-Line Interface reference manual (AG421-96004, March 2007)

154 4 - CONFIGURATION-MODE COMMANDS
protocol connection wan send def-buf-size
Description Sets the WAN default-send buffer size for HSTCP support.
The no command option resets the buffer size to the default.
For detailed information about configuring HSTCP, see “tcp highspeed enable” on
page 193.
Syntax [no] protocol connection wan send def-buf-size <bytes>
Parameters
Usage To configure your WAN buffer size you must increase the WAN buffers to 2
Bandwidth Delay Product (BDP) or 10 MB. You can calculate the BDP WAN buffer
size. For a link of 155 Mbps and 100 ms round-trip delay, the WAN buffers should be
set to:
2 * 155 Mbps * 100 ms = 1937500 bytes
Example
minna (config) # protocol connection wan send def-buf-size 3875000
minna (config) #
protocol mapi enable
Description Messaging Application Programming Interface (MAPI) optimization is enabled by
default. The no command option disables MAPI optimization for testing purposes.
If you are experiencing problems with Outlook clients connecting with Exchange, you
can disable MAPI latency acceleration (while continuing to optimize with SDR for
MAPI) by issuing the no protocol mapi enable command.
Syntax [no] protocol mapi enable
Parameters None
Example
minna (config) # no protocol mapi enable
minna (config) #
protocol mapi 2k3 enable
Description Enables Exchange MAPI 2003 acceleration which allows increased optimization of
traffic between Exchange 2003 and Outlook 2003.
The no command option disables MAPI 2003 support.
Syntax [no] protocol mapi 2k3 enable
Parameters None
<bytes> Specifies the WAN default-send buffer size. The default value is 262140.
