Redundant FCIP network structure example In a high-availability FCIP configuration, pairs of MPX200 routers and two independent IP networks provide full redundancy. Loss of connectivity through one of the IP networks does not result in a loss of connectivity between the fabrics. The redundant configuration can be either a single HP StorageWorks MPX200 Multifunction Router 1-GbE Base Chassis with an HP StorageWorks MPX200 Router 1-GbE Upgrade Blade, or an HP StorageWorks MPX200 Multifunction Router 10-1 GbE Base Chassis with an HP StorageWorks MPX200 Router 10-1 GbE Upgrade Blade. Note that FCIP is currently supported only on MPX200 1 GbE ports. See Figure 78. Figure 78 MPX200 high-availability configuration with fully-redundant long-distance links . Using FCIP to encapsulate FC packets With FCIP, gateways transport FC frames over an IP network. From the perspective of the local and remote fabrics, the FC devices accessed through the gateways appear to be part of one unified fabric. This is possible because FC traffic is carried over the IP network in such a way that the FC fabric and all FC devices on the fabric are unaware of the presence of the IP network. Once configured, FCIP instances on each gateway become active and establish their connectivity through the IP network. The FC devices in the local fabric access the FC devices in the remote fabric using FC frames. The FC frames are encapsulated in IP packets by the local gateway and then transmitted to the remote gateway. The remote gateway strips the IP packet data and passes only the FC frames to the remote FC devices. The gateways deployed for FCIP are configured to use TCP, which uses standard TCP flow control and error recovery algorithms. FCIP Impact on existing iSCSI configurations This guide includes samples of FCIP and iSCSI configurations to illustrate some of the many possible configurations available. Despite the number of permutations, there are really only two basic FCIP configurations: a dedicated FCIP blade and a shared iSCSI/FCIP blade. A dedicated MPX200 blade running only FCIP does not have any impact on a dedicated MPX200 blade running iSCSI. There is, however, an impact and possibly changes required for existing MPX200 iSCSI configurations when FCIP is added to the same blade. Also consider this possibility when planning a new iSCSI/FCIP mixed blade configuration. 118 MPX200 FCIP

Redundant FCIP network structure example

In a high-availability FCIP configuration, pairs of MPX200 routers and two independent IP networks

provide full redundancy. Loss of connectivity through one of the IP networks does not result in a loss

of connectivity between the fabrics.

The redundant configuration can be either a single HP StorageWorks MPX200 Multifunction Router

–

GbE Base Chassis with an HP StorageWorks MPX200 Router 1

–

GbE Upgrade Blade, or an HP

StorageWorks MPX200 Multifunction Router 10

–

1 GbE Base Chassis with an HP StorageWorks

MPX200 Router 10

–

1 GbE Upgrade Blade. Note that FCIP is currently supported only on MPX200

1 GbE ports. See

Figure 78

Figure 78 MPX200 high-availability configuration with fully-redundant long-distance links

Using FCIP to encapsulate FC packets

With FCIP, gateways transport FC frames over an IP network. From the perspective of the local and

remote fabrics, the FC devices accessed through the gateways appear to be part of one unified fabric.

This is possible because FC traffic is carried over the IP network in such a way that the FC fabric and

all FC devices on the fabric are unaware of the presence of the IP network. Once configured, FCIP

instances on each gateway become active and establish their connectivity through the IP network.

The FC devices in the local fabric access the FC devices in the remote fabric using FC frames. The

FC frames are encapsulated in IP packets by the local gateway and then transmitted to the remote

gateway. The remote gateway strips the IP packet data and passes only the FC frames to the remote

FC devices. The gateways deployed for FCIP are configured to use TCP, which uses standard TCP

flow control and error recovery algorithms.

FCIP Impact on existing iSCSI configurations

This guide includes samples of FCIP and iSCSI configurations to illustrate some of the many possible

configurations available. Despite the number of permutations, there are really only two basic FCIP

configurations: a

dedicated FCIP blade

and a

shared iSCSI/FCIP blade

A dedicated MPX200 blade running only FCIP does not have any impact on a dedicated MPX200

blade running iSCSI. There is, however, an impact and possibly changes required for existing MPX200

iSCSI configurations when FCIP is added to the same blade. Also consider this possibility when

planning a new iSCSI/FCIP mixed blade configuration.
