What is Fibre Channel?
•Fibre Channel is a Storage Area Network Used in Data Centers
– NOT Ethernet
– Different cables, ports, and switches

Server Requirements
– Parallel LAN/SAN infrastructure
– Inefficient use of network
infrastructure
– 5+ connections per server to
higher adapter and cabling costs:
• Adds downstream port costs; capital
expenditures and operating expenses
• Each connection adds additional
points of failure in the fabric
– Longer lead time for server
provisioning
– Multiple fault domains to complex
diagnostics
– Management complexity:
firmware, driver patching, and
versioning

GE = Gigabit Ethernet
FC = Fiber Channel
HBA = Host Bus Adapter
Consolidating Ethernet with 10 GE to
the Server
10GE
 10/40 GE ethernet great reduces
the need for Ethernet Port.
 (1) 10GE port = (10) 1 GE ports!
GE = Gigabit Ethernet
Fibre Channel over Ethernet
FCoE
Benefits
 Mapping of FC frames
over Ethernet
 Enables FC to run on a
lossless Data Center
Ethernet network

Fibre
Channel
 Wire Server Once
 Fewer cables and adapters
and switches
 Software Provisioning of I/O
 Interoperates with existing
SANs
 No gateway—stateless
 Standard – June 3, 2009

Non-UNIFIED I/O for Compute
• Consider a deployment of 64 blade servers in 8 chassis
with each blade having three 1Gb network interfaces
and 2 Fibre Channel interfaces and each chassis having
1 management interface
• 328 cables
• Typical Cisco UCS
– 36 cables
– More bandwidth

Unified Computing System
• Unified fabric
• Unified management
• Service profiles
– Allows specification of server
– Provisions all aspects of server
• NICs, VLANs, QoS, UUIDs, WWN, VSAN, BIOS
• High density
• “Wire once” model

– FC or FCoE connectivity to Storage or
SAN
– FCoE connectivity to blade server chassis
– Always installed in pairs
•
Blade Chassis
– (2) Fabric Extenders
– (8) slots per chassis
•
UCS Blade Servers
– B-series blades
• 12 – 32 Cores per blade
– Virtualization Interface Card (VIC)

Cisco UCS Fabric Interconnect
The BRAINS!
• Define a UCS Compute Domain
– Provides unified network connectivity
to chassis and blades
• 10 Gigabit Ethernet
• Fibre Channel over Ethernet (FCoE)
– IP connectivity to IP Aggregation Layer
– IP connectivity for NAS file storage
– Embedded UCS Management

Cisco UCS 6100 Fabric Interconnect
• The management and communication
backbone of a UCS System.
• Provides both network connectivity and
management capabilities to all attached
blades and chassis.
• Line-rate, low-latency, lossless 10 Gigabit
Ethernet and Fibre Channel over Ethernet
(FCoE) functions.
• Typically deployed in redundant pairs.
