PowerEdge M1000e Technical Guide 46
The M1000e system management hardware and software includes Fabric Consistency Checking,
preventing the accidental activation of any misconfigured fabric device on a server module. The
system will automatically detect this misconfiguration and alert the user of the error. No damage
occurs to the system, and the user will have the ability to reconfigure the faulted module.
M1000e I/O is fully scalable to current and future generations of server modules and I/O Modules.
There are three redundant multi‐lane fabrics in the system, as illustrated in Figure 29.
In its original configuration, the M1000e midplane is enabled to support up to four Gigabit Ethernet
links per server module on Fabric A. Thus, potential data bandwidth for Fabric A is 4 Gbps per half-
height server module. A future midplane upgrade may enable higher bandwidth on Fabric A.
The M1000e provides full 10/100/1000M Ethernet support when using Ethernet passthrough modules
enabling you to connect to any legacy infrastructure whether using Ethernet passthrough or switch
technology. This technical advance uses in-band signaling on 1000BASE‐KX transport and requires no
user interaction for enablement.
Figure 29. High Speed I/O Architecture
Fabric B and C are identical, fully customizable fabrics, routed as two sets of four lanes from
mezzanine cards on the server modules to the I/O Modules in the rear of the chassis. Supported
bandwidth ranges from 1 to 10 Gbps per lane depending on the fabric type used.
