Recently, Cisco released the latest component for their UCS architecture, the 6324 Fabric Interconnect.
The new FI replaces the 2000 series Fabric Extender IOM in the 5108 Blade chassis, and provides the same management capabilities and XML API as the full sized rack mounted Fabric Interconnects. Obviously this form factor supports a smaller UCS domain (8 Blades and up to 4 C series rack mounts), but is ideal for somewhere that doesn’t require all the expansion capabilities of a full-scale UCS solution.
So let’s look at the high level architecture of the 6324. It’s IOM form factor will save rack space over the full size FI, and will provide up to 500Gbps switching capacity, 80Gbps uplink bandwidth per chassis, and 20Gbps per FI to each server. As is standard in UCS-world, they support lossless 10GbE unified fabric capabilities and FCoE.
Each FI supports the following:
- 4 SFP+ ports, supporting 1GbE, 10GbE, FC, or FCoE
- 1 QSFP+ port, supporting 40GbE or FCoE
- 16 10GBASE-KR lanes as server ports
- 500Gbps throughput
- Sub-microsecond latency
- 16 QoS hardware queues
There’s much more information on Cisco’s datasheet here, but that covers off the main technical information around the new FI.
I’m looking forward to seeing some pricing information around these, if the price point matches the market that these are aimed at I expect to be seeing a lot of them in the next few months.
