Quadport Capable Hardware for the M1000e Modular Chassis

Page 2

Introduction:

The Dell M1000e Modular chassis brings a rich assortment of IO capabilities into a relatively small space.

This document introduces QuadPort Mezzanine Cards and PowerConnect M6348 switch that further scales

Network density.

The M1000e Chassis, Blades and IO Modules

The M1000e chassis supports up to 16 Half Height server blades, 8 full height server blades or a logical mix of the

two. It also supports up to 6 IO Modules. We will focus on the Intel Quadport Gigabit ET Mezzanine card, the

Broadcom NetExtreme II 5709 Quad Port Ethernet Mezzanine Card, and the Dell PowerConnect M6348 switch

IOM.

IO Fabric Banks

Chassis IO is segregated into 3 discrete data paths by letter: A, B and C. These paths are described as “FABRICS”

and support Ethernet, Fibre Channel or InfiniBand. These discrete fabric paths are split into 2 IO “Banks”, bank one

and two. Each Blade IO adapter can have either 2 or 4 ports depending on capability. These ports are split out

evenly to IOM banks one and two to allow for redundancy. When you deploy your Ethernet, iSCSI or FibreChannel

networks, span their redundant links across banks one and two for maximum availability. We denote the discrete

IOM with the fabric Identifier and the Bank number.

Example: “A1” denotes Fabric “A” in bank “1”. “C2” Denotes Fabric “C” in Bank “2”. This translates into the

following logical mapping in figure one and the physical layout in figure two.

Figure 1 shows a half height blade with dual port LOMS and Mezzanine Cards and dual capable IOM’s. Figure 2

shows the numbering of each IOM slot and IOM banks one and two and six Dell Gigabit Ethernet pass-through

modules installed in all 6 IOM bays.

TechNote: “Quad port ” implies these components are fully compatible

with other Quadport devices. Quadport capable devices are also

compatible with “dual port” devices minus the availability of connectivity

with the 2

pair of IO channels
