HP StorageWorks 6100 - Enterprise Virtual Array User Manual page 76

• Local IP Address The IP address to be used by the GigE port. An uninitialized port has an IP
address of all zeros.
• Remote IP Address The IP address of the GigE port on the remote router.
• Subnet Mask The subnet mask used by the GigE port.
• Gateway IP Address The gateway IP address used by the GigE port.
• Jumbo Frames Provides a dialog box for enabling and disabling Jumbo IP frames. When disabled,
the MTU is 1,500 bytes; when enabled, the maximum MTU is 9,000 bytes. When other is se-
lected, the MTU size can be set between 1,000 and 9,000 bytes.
• TCP Window Size Contains a dialog box that provides three options for TCP window size: 8,192,
16, 384, and 32,768 bytes. The default is 32,768.
• Window Scaling Contains a dialog box that provides for enabling and disabling TCP window
scaling. The default is Disabled. When enabled, the Window Scaling Factor is used.
• Window Scaling Factor Contains a dialog box that provides six options for TCP window scaling:
0, 1, 2, 3, 4, 5, 6, and 7.
• TCP Port Number Provides a dialog box that enables the user to define the destination TCP port
number used by the FCIP route. This port number must be the same on both routers participating
in the FCIP route (local and remote routers must be using same port number). The default port
number used by FCIP is 3225.
• GigE Port Speed Provides a dialog box that contains four options for the GigE port speed: Auto,
10, 100, and 1000: The port speed rate is Auto.
• Port Speed Mode Provides a dialog box that contains three options for the link rate mode: Auto,
half duplex, and full duplex. This dialog box is available only when the GigE port speed is set to
something other than Auto.
• GigE Port Flow Control Provides a dialog box for enabling and disabling GigE port flow control.
The default is Enabled. This dialog box is available only when the GigE port speed is set to
something other than Auto.
• VLAN Enabled Provides a dialog box for enabling and disabling VLAN support. The default is
Disabled.
• VLAN ID Provides a dialog box that enables the user to define the VLAN ID. This dialog box is
available only when VLAN is enabled. The VLAN ID must be the same on both gateways particip-
ating in the FCIP route (local and remote gateways must be using same VLAN ID) and the Ethernet
switches.
• VLAN Priority Provides a dialog box that contains eight options for the VLAN priority: 0 through
7. This dialog box is available only when VLAN is Enabled.
• FCIP SW Compression Provides a dialog box for enabling and disabling FCIP compression. The
default is Disabled.
• Bandwidth (Mbit/sec) Provides a dialog box that enables the user to define the maximum
bandwidth (in Mb/s) used by the GigE port during transmits. The range of values supported is 1
to 1,000 Mb/s. This setting enables the user to limit the bandwidth used by the FCIP route so as
not to consume all the available link bandwidth. For example, if the slowest link in the WAN being
used is a DS-3 link, then the maximum available bandwidth is 45 Mb/s. To limit the FCIP route
to 33% of the overall link bandwidth, set the bandwidth to 15 Mb/s.
HP StorageWorks Continuous Access EVA/XP replication solution requires dedicated bandwidth
for the intersite link. If other applications share the intersite link, some method of QoS must be
used to ensure that the replication application has uncontested access to the allocated bandwidth.
