For your edge-core-cloud scenarios

Networking solutions

Fujitsu has developed a suite of top-of-rack switches that support flexible and efficient scale-out server infrastructures, especially in combination with new modular servers. This approach results in several improvements, including infrastructure efficiency for cloud computing, end-to-end virtualization and consolidation. Close partnerships with network technology partners complement the portfolio for building complete IT infrastructures. Storage-area networks (SANs) will continue to be the backbone of the data center network for the next investment cycle, but they need enhancements in terms of bandwidth and management functions. To do this, Fujitsu partners with Broadcom, which recently acquired Brocade, the leading provider of SAN switches. And a lot of new use cases are based on Ethernet networks, with bandwidths of up to 100 Gbit and increasingly virtualized fabric architectures for building dynamic data centers. Fujitsu also partners with Extreme Networks, which offers the best of breed, high performance IP Networking Switches. And it goes without saying that Fujitsu server and storage systems are fully compatible with products from all important network switch vendors, including Cisco.

UltraScale ICL trunking - - - - - - - Chassis-to-chassis linkage through connectors on the Core Routing (CR) blade Can configure the following maximum QSFPs per trunk depending on blade type, connecting:
  • Up to four 4×32 Gbps QSFP ports in a trunk group to form a 512 Gbps trunk between two Brocade CR32-4 blades. For trunks containing four or fewer QSFP ports, ports in a trunk must be located in the same port group on each blade
  • Up to four 4×32 Gbps QSFP ports in a trunk group to form a 512 Gbps trunk between a Brocade CR32-4 and CR32-8 blade. For trunks containing four or fewer QSFP ports, ports in a trunk must be located in the same port group on each blade. A minimum of two QSFP connections are required for a trunk, and up to four 4×16 Gbps QSFP trunks between pairs of Brocade CR32-8 (CR32-4) and CR16-8 (CR16-4).
