Dell M1000e Maximum Theoretical Bandwidth
• Two switches with up to two data lanes per blade (4 lanes)
• Four switches with up to four data lanes per blade (16 lanes)
This configuration appears to provide the highest theoretical bandwidth possible.
To calculate the maximum theoretical bandwidth using the same assumptions described above, the Dell M1000e chassis would have 16 blades with 20 data lanes each, or 320 total data lanes:
• 170Gbps half-duplex per blade (4 data lane at 2.5Gbps each in Fabric A(2 data lane = 1.25Gbps x Quad Port) and 16 data lane at 10Gbps each in Fabric B and C, inbound or outbound)
• 340Gbps full-duplex per blade (inbound and outbound data rates added together)
• 5.44Tbps full-duplex per chassis (16 blades x 340Gbps)
This value base in 2008
Currently,
Fabric A – 2 (RDNT) x 10Gb (10Gb DP) x 2 (full-duplex) = 40Gb
Fabric B – 2 (RDNT) x 56Gb (FDR IB) x 2 (full-duplex) = 224Gb
Fabric C – 2 (RDNT) x 56Gb (FDR IB) x 2 (full-duplex) = 224Gb
488Gb per blade full duplex x 16 blades = 7.808Tb
