FCIP is supported between pairs of 1606 Extension SAN Switches and DC Dir Switch MP Extension
Blades, or between a 1606 Extension SAN Switch and a DC Dir Switch MP Extension Blade.
10 FCIP is not supported in between the 1606 Extension SAN Switch or DC Dir Switch MP Extension
Blade and the MP Router, 400 MP Router, or MP Router Blade. See
SAN Switch and DC Dir Switch MP Extension
FCIP tunnels (virtual E_Ports) pass traffic between the SAN extension devices.
11 The 1606 Extension SAN Switch supports up to 8 FCIP tunnels.
The DC Dir Switch MP Extension Blade supports up to 20 FCIP tunnels.
IPsec is not supported on the 1606 Extension SAN Switch or DC Dir Switch MP Extension Blade
12
running Fabric OS 6.3.0.
FCIP FastWrite and Fibre Channel FastWrite support:
FCIP is supported with FCIP FastWrite SCSI write acceleration when using firmware 6.3.0a
or later with XP Continuous Access. FCIP FastWrite is not supported with Continuous Access
EVA.
13
Note: FCIP FastWrite and IPsec are mutually exclusive and cannot be configured simultaneously.
Fibre Channel FastWrite—FC FastWrite is currently not supported with the 1606 Extension
SAN Switch or DC Dir Switch MP Extension Blade.
For redundancy, HP recommends using a minimum of two EX_Ports (router IFLs) for each fabric
connected to a 1606 Extension SAN Switch or DC Dir Switch MP Extension Blade. The number
of EX_Ports required is based on the performance requirements for all devices shared by fabrics
through the router.
14
Calculate the number of EX_Ports using a 5:1 ratio of standard ISLs or switch device ports to
router EX_Port IFLs. Monitor port performance to determine if this ratio is acceptable based
on usage. Use the portperfshow command to monitor router port performance.
For very high bandwidth requirements and applications, use a ratio of 3:1 or 1:1.
Supports routing between B-series secured and nonsecured edge fabrics using advanced security
15
features or ACLs.
Supports routing between B-series and M-series/McDATA edge fabrics. See the HP StorageWorks
Fabric interoperability: Merging fabrics based on M-series and B-series Fibre Channel switches
application notes at http://hp.com/go/sdgmanuals.
16
Note: Continuous Access products are not supported in routed fabrics using both B-series and
M-series/McDATA edge fabrics.
Supports the following features:
8 Gb/s on FC ports
17 FCIP Trunking
Adaptive Rate Limiting
10 GbE ports (DC Dir Switch MP Extension Blade)
