1. Abstract
The goal of this document is to model and define management MIB for the
FCIP device so that it can be part of an enterprise class storage
network. The FCIP device is specified in the Internet-draft
<draft-ietf-ips-fcovertcpip-02.txt> [1].
Since the FCIP device is one of the SAN fabric devices, the FCIP
management
MIB is defined such that it can extend the existing framework MIB, which
is specified in <draft-ietf-ipfc-fcmgmt-int-mib-06.txt> [2], to model
the new FCIP device under the existing overall FC management framework.
This approach will enable the FCIP devices to integrate smoothly into
the SAN integrated management environment for the enterprise customer.
2. Overview of FCIP-Device Based Interconnection Model
Note that the FCIP-Device is fully described in [1] from functional
point of view; whereas this section describes the FCIP-Device from
management point of view.
The FCIP device is modeled as a "gateway" FC Connectivity Unit as the
FCIP device acts as a gateway connection unit to bridge the FC onto the
IP technology.
The FCIP-devices provides IP-based interconnection model to interconnect
the FC fabric elements. In this model, the FCIP-devices, along with
their IP-network, provides a new FCIP transport network. The FC fabric
elements (FC-FEs) will support the Logical FC Links in their overlay
network that resides on this FCIP transport network.
This IP-based FCIP Interconnection Model supports the following
topology:
- The FCIP-based transport network is formed by
interconnecting the FCIP-devices.
- The peer FCIP-devices are interconnected by the Virtual-
Links.
? An FCIP-device establishes Virtual-Links with its
peer FCIP devices.
? There will be only one Virtual-Link between two
peer FCIP devices.
- A single Virtual-Link consists of multiple sets of TCP
connections (known as the TCP Links in this document).
? There could be one of set of TCP links for
transmitting FC frames.
? There could be another set of TCP links for
transmitting control and priority messages.
- An FCIP-device may have one or more FCIP-endpoints (known
as the FCIP-ports in this document) facing the IP network.
? One FCIP-port can be used to form one or more
Virtual-Links.
- An FCIP-device may have one or more B-ports or E-Ports
facing the FC fabric side.
? These ports might connect one or more FC-FEs to the
FCIP-device.
? If the B-port is used to connect the neighboring
FC-FE and FCIP_device, it establishes a bridge-
links between the FC-FE and FCIP-device.
- The FCIP-device can work as a stand-alone box or as part
of a FC fabric element.
The MIB specified in this document supports the above FCIP-devices,
FCIP-based transport network, and FC overlay network under the existing
overall FC management framework [2] by extending/augmenting the
framework MIB [2].
Note that a Virtual Inter-Switch Link, as per [1], is a Logical FC Link
between two E-ports. The association between the Virtual Inter-Switch
Link (Virtual-Link) and the related Virtual-Links and Bridge-Links is as
follows:
? One Virtual Inter-Switch Link spans one Virtual-Link if both the
FCIP-devices, through which this Virtual-Link passes through,
operate in E-port mode.
? One Virtual Inter-Switch Link spans one Virtual-Link and two
Bridge-Links if both the FCIP-devices, through which this Virtual-
Link passes through, operate in B-port mode.
? One Virtual Inter-Switch Link spans one Virtual-Link and one
Bridge-Link if one FCIP-device operates in B-port mode and the
other FCIP-Device operates in E-port mode.
