NOTE:
VEX_Ports and EX_Ports cannot connect to the same edge fabric.
VEX_Ports are not supported with the DC Dir Switch MP Extension Blade.
Using FCIP and Fibre Channel routing, you can connect to local and remote fabrics without fully
merging them. This prevents unauthorized access to all devices on the local and remote fabrics.
1606 Extension SAN Switch and DC Dir Switch MP Extension Blade features and requirements
Table 150 lists the features and requirements for the 1606 Extension SAN Switch and DC Dir Switch MP Extension
Blade.
Table 150 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade features and requirements
RequirementsFeature
The 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade are supported
with the B-series switches listed in “B-series switches and fabric rules” on page 93.
These products are also supported for use as Fibre Channel switches. This provides both
Fibre Channel switch connectivity for hosts and storage systems and FCIP connectivity for
SAN extension.
Fibre Channel switches for FCIP
TCP/IP IPv4, Ethernet 10 Mb/s, 100 Mb/s, and 1,000 Mb/s
All 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade FCIP
implementations must have dedicated IP bandwidth configured as a committed bandwidth,
or using the Adaptive Rate Limiting feature. HP does not support the 1606 Extension SAN
Switch and DC Dir Switch MP Extension Blade configurations with FCIP tunnels configured
with nondedicated bandwidth. For more information, see “Configuring and monitoring
FCIP extension services” in the HP StorageWorks Fabric OS 6.x administrator guide.
For more information on dedicated IP bandwidth requirements, see Table 157 and Table
161.
Notes:
• XP Continuous Access storage systems require a minimum of 16 Mb/s IP bandwidth.
• FCIP is supported with IPsec data encryption (license required). This requires a min-
imum of firmware 6.3.0.
• FCIP is supported with FCIP FastWrite acceleration.
• The connection to the 1606 Extension SAN Switch or DC Dir Switch MP Extension
Blade FCIP port must be GbE compatible (10 GbE for the 10 GbE ports).
IP network protocols
Continuous Access EVA:
Continuous Access XP20000/24000, XP10000/12000. This requires a minimum of
firmware 6.3.0a.
See “Heterogeneous server rules” on page 185 for operating system support.
FCIP FastWrite is supported with XP Continuous Access and is not supported with
Continuous Access EVA.
Note: Use aptpolicy = 1 (port-based routing) and DLS = 0FF (dynamic load sharing) with
B-series switches, 1606 Extension SAN Switches, or DC Dir Switch MP Extension Blades
using Continuous Access EVA. XP Continuous Access supports aptpolicy = 1 and aptpolicy
= 3 (exchange-based routing) (see Table 176).
