Fibre Channel over Ethernet (FCoE)
Summary
– Network Convergence promises to deliver reduced cost and complexity
when provisioning and managing data center services
•
•
•
Reduced infrastructure costs by leveraging common fabric elements
Reduced administration costs by consolidating management
Quicker time to deployment by rebalancing and allocating fabric resources to new services
– I/O Consolidation is the logical first ‘incremental’ step which can deliver 80%
of the benefits of total convergence solution to simplify data center networks
and reduce costs
•
•
FlexFabric offers reduced cost and complexity and a migration path to 10G connectivity while
helping to ensure business continuity
Storage I/O Consolidation via FCoE can leverage and extend existing Ethernet and Fibre
Channel storage networks investments
– Customers want standards-based products that will support full Network
Convergence when these ‘solutions’ are fully-developed
•

Fibre Channel over Ethernet (FCoE), the protocol, is a standard. FCoE for Network Convergence
-(end-to-end implementation), requires data center bridging (DCB) protocols, which are not yet
ready for prime-time
HP offers a full range of tested and certified I/O consolidation products and solutions that
provide immediate benefits and will support future Network Convergence deployments

Fibre Channel over Ethernet (FCoE)
Background
– Convergence - of networks, infrastructure, technologies is a trend ultimately driven by virtualization and the desire
to reduce the cost and complexity that can result from
networks deployed to address it - partly reality, partly hype
– Storage networking has strict requirements and
imperatives required to ensure proper operation
• Lossless
delivery, high performance, vendor end-to-end testing and
integration to ensure solution integrity
• Customers
deploy and manage Fibre Channel Storage Area
Networks (FC-SANs) separately (w/dedicated staff) from Ethernet
networks

FCoE/DCB/CEE technologies
– Fibre Channel (FC) is a gigabit-speed network technology standard
used for storage networking and Storage Area Networks (SANs)
– Fibre Channel over Ethernet (FCoE), supported by a list of data center
bridging (DCB) protocols (DCB + enhancements to Ethernet =
Converged Enhanced Ethernet - CEE), allows Fibre Channel traffic to
run over 10 Gbps Ethernet networks
Ethernet
Fibre
Channel
– FC requires high performance and ‘lossless’ operation (ie dropped
packets not allowed)  FCoE/CEE must ensure lossless operations
– FCoE has been ratified, the complete set of DCB/CEE protocols has

FCoE Sales Overview
Network Convergence vs I/O Consolidation
– Network Convergence = collapsing FC-SANs onto Ethernet networks
(storage I/O all the way to storage devices, including FC switches/directors)
•
Requires full DCB support, implies substantial realignment of server/storage management practices
•
NOT supported by standards today
– I/O Consolidation = consolidating infrastructure at the server edge only (FC +
Ethernet server interfaces, FC + LAN switches)
•
Requires only partial DCB support, minimal impact on existing server/storage management
practices
•
Supported by standards today

I/O Consolidation Benefits
– Reduced cost/complexity (at the server edge - where it
has the biggest positive impact):
• Fewer
CNAs instead of multiple NICs and HBAs
• Fewer
FCoE switches instead of dedicated Ethernet and FC switches
• Fewer
SFP+ cables instead of dedicated Ethernet and FC cables
– High performance migration path: can be a
‘springboard’ to jump from older 100Mbps/2/4 Gbps FC to
10GbE/8Gb FC technology
– Business Continuity: compatible with existing FC SANs
(FC directors, FC storage systems), does not disrupt
existing storage/server network management models

HP position and recommendations
– I/O consolidation = a good 1st step in the evolving journey to full-blown
network convergence which will track to the development of DCB/CEE
standards-development (in which HP has a leadership role)
– Longer-term network convergence will require further standards
development and new operating & management models (storage<>networking)
– This is storage networking - imperatives that apply to ‘pure’ FC storage
networks also apply here; end-to-end certification required for assured
operation (as provided by HP)
– Focus on solving real problems (e.g. improving economies and simplifying the
network where you can have the greatest impact), don’t jeopardize ongoing
operations
– Adopt more aggressive convergence strategies in alignment with business
objectives and as protocols mature (don’t get locked into proprietary/prestandard end-end FCoE implementations)

The Convergence Challenge…
What’s Right For Your Business?
Convergence Objectives
Challenges to Address
• Reduce LAN & SAN costs
• Governance
− less equipment to buy, install
& maintain
− less to power and cool
− less management effort
− who “owns” infrastructure
management responsibility?
• Performance
− how to maintain end-to-end
performance?
• Infrastructure
− How to transition infrastructure
deployment and management
to a ‘converged’ infrastructure

Converge First At The Server Edge
The server edge
is most complex
Far less complexity
beyond server edge
• Most cables connect servers to
edge (access) switches
• Most switches connect to servers
Core
Switch
• Most data traffic is server to server
• Many workloads sharing one edge
• More NICs to connect
• More switches to connect
• More cables and clutter
Biggest opportunity for
consolidation

Use top-of-rack switching for I/O virtualization and
convergence; the 80/20 Benefits rule applies
Key Findings
– Top-of-rack convergence provides the largest benefit with the least disruption.
– Using a single technology for LAN and storage area network (SAN) access
within the rack can deliver savings without requiring a converged backbone.
– Although the FCoE standard has been approved, it is only a piece of the
standards puzzle required to construct converged networks
Recommendations
– If you decide to adopt FCoE/(CEE) as your I/O virtualization technology, use a
phased approach to deployment to avoid vendor lock-in and increased long-term
costs.
– Be wary of vendor claims that you can build a standards-compliant end-to-end
converged data center network today, or within the next 18 months.

HP’s FCoE Strategy
– Non-proprietary solutions must be flexible and
provide long term investment protection
– Convergence at the server edge (I/O consolidation)
is the most difficult…but also provides the biggest
ROI
– Networks using HP’s BladeSystem Virtual Connect FlexFabric Module
can provide immediate benefits of I/O consolidation with the ultimate in
deployment simplicity and flexibility
– Networks using HP’s A5820 FCoE solution can offer unprecedented
modular resiliency and flexible service delivery in a fixed form factor at
a disruptive price point
– HP partners with top OEM companies to ensure open compatibility and
choice

Ethernet
− CEE is new Ethernet infrastructure that implements DCB
− The term “CEE” was coined by an ad hoc industry group that put
together the original proposals for DCB to the IEEE
− There are hardware and software changes required for CEE,
so legacy Ethernet gear is not designed for converged traffic
