extreme levels of availability—the ability to scale dynamically
without having to reconfigure their network devices—while also
minimizing costs and downtime. IBM System Networking uses
industry-leading Layer 2-7 Ethernet switching experience to
deliver iFlow Director (patents pending)1—a high-throughput,
low-latency, traffic load distribution system in a 10 Gbps
Ethernet switch for BladeCenter H and HT.
IBM iFlow Director
High availability and reliability
iFlow Director is designed with a number of advanced features
to deliver high availability in mission-critical environments.
The solution is built around industry-leading hardware to
help eliminate any single point of failure. iFlow Director uses
BladeCenter innovations—like internal monitoring, redundant
mid-plane, redundant network connections per blade, redun-
dant power supplies and fans—and switching features like
uplink failure detection and controlled failover with network
interface card (NIC) teaming to deliver high availability.
Supported BladeCenter chassis
iFlow Director also includes these high availability features:
