This month Cisco announced a new addition to the UCS family – a mini Fabric Interconnect, called the UCS 6324 Fabric Interconnect, which unlike the ones before it plugs directly into the UCS 5108 chassis. With connectivity for up to 15 servers (8 blade servers and up to 7 direct-connect rack servers), the 6324 is geared toward small environments.
6324 FI Overview
- 16 x 10GbE internal ports (2 per 1/2 width slot)
- 4 x 10Gb SFP+ external uplink ports
- 1 x 40Gb QSFP+ scalability port
- 1 x 10/100/1000 Mbps Management port for out-of-band management
The 4 external uplink ports can be configured as 1/10 Gigabit Ethernet or 2/4/8-Gbps Fibre Channel ports. The scalability port is designed to allow for connectivity to up to 4 x UCS rack servers with a post-release feature of also allowing a 2nd UCS 5108 chassis to interconnect.
The 6324 FI provides Layer 2 forwarding with support for:
- VLAN trunks
- IEEE 802.1Q VLAN encapsulation
- Support for up to 512 VLANs and 32 virtual SANs (VSANs) per interconnect
- Jumbo frames on all ports (up to 9216 bytes)
- Link Aggregation Control Protocol (LACP): IEEE 802.3ad
- Internet Group Management Protocol (IGMP) Versions 1, 2, and 3 snooping
- Advanced EtherChannel hashing based on Layer 2, 3, and 4 information
- Pause frames (IEEE 802.3x)
- Layer 2 IEEE 802.1p (class of service [CoS])
It is also rumored that UPDATED – based on the information from UCSGuru (below) a new an updated UCS 5108 blade chassis will be coming out soon which will allow for heartbeat and cluster connectivity between the UCS 6324 FI modules inside a chassis as well as support for “dual voltage” power supplies.
