Description
HP offers multiple FCoE solutions, from fabric-edge solutions using FCoE CNAs and CN switches
integrated with existing FC target environments, to full FCoE end-to-end solutions using CNAs, CN
switches and FCoE storage targets.
The HP FCoE fabric-edge solution deploys FCoE technology in existing Ethernet and FC environments
with the benefit of convergence at the server and fabric edge using CNAs and CN switches. This
solution provides this benefit in addition to investment protection by allowing FCoE to be integrated
with existing HP Fibre Channel SANs.
The HP end-to-end FCoE solution for EVA storage systems provides an FCoE technology implementation
from server to storage. This solution consists of FCoE CNAs, CN switches, and FCoE storage targets
using the MPX200 Multifunction Router integrated with the EVA family of storage systems. Two FCoE
end-to-end configurations are supported:
• Direct-connect—Provides 10-GbE FCoE and optionally, iSCSI connectivity for up to two EVA storage
systems without requiring any Fibre Channel switches.
• Fabric-connect—Provides additional connectivity, allowing for up to four EVA storage systems using
a fabric connection between the MPX200 and EVAs.
The FCoE product set consists of the following:
• HP B-series and C-series CN switches—Provide a bridge function from the CN to separate Ethernet
and FC fabrics, or support end-to-end FCoE when used with CNAs and the MPX200 with FCoE
target functionality
• HP CN1000E and CN1000Q CNAs—Converge Ethernet and FC technologies in the server over
10-GbE links to converged network switches
• HP MPX200 Multifunction Router FCoE—Provides FCoE target functionality when integrated with
EVA storage systems (for more information, see the HP StorageWorks SAN Design Reference
Guide and the HP StorageWorks MPX200 Multifunction Router User Guide).
Benefits
This section describes some of the benefits of FCoE technology. The convergence of Ethernet and FC
provides the same level of connectivity as previous technologies, but requires:
• 50% fewer switches in each server rack—Only two CN ToR switches, compared with four (two
network and two FC) switches per rack with separate Ethernet and FC switches
• 50% fewer adapters per server
• 75% fewer cable connections
