Ethernet Growth Path
The M1000e is designed for full support of all near-, medium- and long-term I/O infrastructure needs.
While the M1000e system’s bandwidth capabilities lead the industry, the M1000e is also intelligently
designed for maximum cost, flexibility and performance benefit.
While Fabric A is dedicated to the server module LOMs, requiring Ethernet switch or passthrough
modules for I/O slots A1 and A2, Fabrics B and C can be populated with Ethernet, Fibre Channel, or
InfiniBand solutions.
