Power Supply |
Two Power Supplies (AC or DC) |
Management by Cisco UCS Manager |
- Increases flexibility with a range of interconnect solutions, including copper Twinax cable for short runs and fiber for long runs
- Consumes less power per port than traditional solution
- Helps enable cost-effective connections on fabric extenders with Cisco Fabric Extender Transceiver (FET) optics
- Allows all elements connected to the interconnects to participate in a single, highly available management domain
|
Unified Fabric |
- Decreases total cost of ownership (TCO) by reducing the number of NICs, HBAs, switches, and cables needed
- Transparently encapsulates Fibre Channel packets into Ethernet
|
Fabric Extender Architecture |
- Scales to 20 chassis without adding complexity by eliminating the need for dedicated chassis management and blade switches and by reducing the number of cables needed
- Provides deterministic latency for optimized application performance
|
SFP+ ports |
- Increases flexibility with a range of interconnect solutions, including copper Twinax cable for short runs and fiber for long runs
- Consumes less power per port than traditional solutions
- Helps enable cost-effective connections on fabric extenders with Cisco Fabric Extender Transceiver (FET) optics
|
SFP28-compatible ports |
Allows fixed ports to be configured to operate in 10/25 Gigabit Ethernet mode with the transceiver options specified for use with SFP28-compatible ports |
QSFP28-compatible Ports |
Allows all ports to be configured to operate in 40/100 Gigabit Ethernet mode with the transceiver options specified for use with QSFP28-compatible ports |
Transceivers |
The Cisco UCS 6400 series FIs support a wide variety of 10/25/40/100 Gigabit Ethernet connectivity options using Cisco 10/25/40/100 Gbps modules. Unified ports (UP) on the Cisco UCS 6400 series FIs support 10/25 Gigabit Ethernet connectivity or 8/16/32 Gigabit Fibre Channel. |
Port-based Licensing |
Helps enable a pay-as-you-go model, allowing customers to add capacity as the networking needs of an individual system increase |
Front-to-Back Cooling |
Fan side intake, port side exhaust |
Redundant hot-swappable fans and power supplies |
- Helps enable high availability in multiple configurations
- Increases serviceability
- Provides uninterrupted service during maintenance
|
Rear Ports |
Helps keep cable lengths short and efficient |
Performance |
- Provides high-speed, low-latency connectivity to the chassis
- Provides approximately 50% reduction in end-to-end system latency (latency is less than 1 microseconds)
|
Lossless Fabric |
Provides a reliable, robust foundation for unifying LAN and SAN traffic on a single transport |
Priority Flow Control (PFC) |
- Simplifies management of multiple traffic flows over a single network link
- Supports different classes of service, helping enable both lossless and classic Ethernet on the same fabric
|
Systemwide Bandwidth Management |
Helps enable consistent and coherent quality of service (QoS) throughout the system |
