Dual port and Quadport IOM’s. Dell PowerEdge M1000e

Quadport Capable Hardware for the M1000e Modular Chassis

Dual port and Quadport IOM’s

The IO Modules are split into 2 types, Pass-through modules and Switches. We will focus on the PowerConnect

M6348 Ethernet switch IOM.

The M6348 is a 48 port switch with 32 internal ports meaning there are double the incoming or internal Ethernet ports compared to a dual port switch where standard dual port IOM’s have 16 internal ports. These 32 ports are mapped in a one to one ratio with the outgoing ports from a Quadport Mezzanine card. All switches have external outgoing or uplink ports. It is suggested that a quadport mezzanine will always be matched with a quad port switch like the M6348.

TechNote: Internal ports are the ports that face internally into the chassis and the external ports are the ports used to uplink to the core fabric

IO Adapters

All Dell blades feature embedded Ethernet Controllers with at least 2 discrete ports. These discrete ports are directly mapped to IOM’s installed in Fabric “A”, banks one and two. IOM slots “A1” and “A2” can only accept

Ethernet IO Modules.

Optional IO adapters or “Mezzanine cards” can be installed in a server blade to enable fabric B and C. These mezzanine cards can be dual port or Quadport. An Ethernet Mezzanine card installed in Fabric B slot in a blade will enable a Matching Ethernet IO Module to be placed in IOM slots B1 and B2. The same population rule applies for fabric “C”.

Technote: Some blades cannot support full IO capability in Fabric "C".

Refer to the IO limitation chart in this document for details

Mezzanine Card Enumeration

Mezzanine cards are identified and ordered by: MEZZn_FAB_x. Where n is 1 to the maximum number of mezz card slots in the blade, and X is the fabric position of the mezz card, either “B” or “C”. Figure 8 shows this numbering in a half height and full height blade
