6 Scaling VCF Domains Beyond a Single MX7000 Chassis | Document ID
2 Dell EMC PowerEdge MX7000
With kinetic architecture and Agile management, the PowerEdge MX portfolio dynamically configures
compute, storage, and fabric, increases team effectiveness, and accelerates operations. The responsive
design delivers the innovation and longevity customers of all sizes need for their IT and digital business
transformations.
Key features of PowerEdge MX7000 include:
• 7U modular enclosure with eight slots that can accommodate 2S single or four 4S double-width
compute sleds and 12 Gb/s single-width storage sleds.
• 25 Gb Ethernet, 12 Gb SAS, and 32 Gb Fiber channel I/O options.
• Three I/O network fabrics—two for general use and one for storage only; each with redundant
modules.
• Multichassis networking up to 10 chassis.
• Single management point for compute, storage, and networking.
• High-speed technology connections, now and into the future, with no midplane upgrade.
2.1 MX7000 Chassis Group
MX7000 supports the creation of an MCM (Multi Chassis Management) Group. An MCM group is one or more
MX7000 chassis that are cabled and configured to be managed from a single lead chassis. The MCM group
allows all the resources of the lead and member chassis to be managed from the OME-Modular interface of
the lead chassis. MCM groups can span from a single MX7000 chassis up to a maximum of 20 MX7000
chassis.
There must be two MX9002m management modules in every chassis of an MCM group. Even in a single
member MCM group both management modules must be present.
MCM groups are defined by the PowerEdge MX9002m management modules. MCM groups can be created
with a single chassis and then expanded as more chassis are cabled together. Since there are no IOMs that
support a network fabric capable of spanning 20 chassis a single MCM group can contain multiple network
fabrics.
A backup lead chassis can be assigned in the event that the lead chassis becomes unavailable. Before an
MCM group of two or more chassis can be created the PowerEdge MX9002m modules must be cabled
together as shown in figure 1.
