Green Data Center Design and Management: Data Center Design Consideration: Meet Me Rooms (MMR)
Meet me rooms provide high bandwidth connectivity directly within the data To be of practical use, telecom carrier links and data center cages need to be. In contrast, a true definition of a meet-me room (MMR) is a physical space (two for redundancy) located in the building envelope of a colocation. A "meet-me room" (MMR) is a place within a colocation centre (or carrier hotel) where telecommunications companies can physically connect to one another and.
The following discussion outlines alternative solutions to ameliorate these kinds of challenges and present some best practices. Space Requirements Although this observation will not help me win friends with carriers and Internet providers, the unstated goal of outside sales staff working for service providers is to grab as much space as they can in a new facility, thereby limiting the available space for competitors.
I am not suggesting this is a sanctioned practice; it is, however, the reality in the competitive colo market. The goal of the data center operator here should be to involve service providers early in the process and to provide space in the MMR for each of them, within reason. If you are too tough on the carrier, remember this—they need not choose your facility, and should you alienate any carriers, the pool of potential tenants will likewise decrease.
An occasional, gentle reminder of this fact normally paves the way to an agreement on space requirements. Cabinets A carrier will generally ask for at least two four-post, inch-high cabinets in each MMR using our model of a ,square-foot colocation facility with redundant connections.
If the operator is providing only AC power, the carrier may request additional rack space for rectifiers and batteries, should they be using DC equipment.

The best practice is to meet with the intended carriers all at once to create a rack and space solution that they can all agree on. Although this may be a difficult task to schedule, it will be worthwhile to reach an agreement on one typical rack type and one layout look and feel.
Clients who inspect your facility before signing a contract will appreciate a consistent look to this space. Permitting odd-size cabinets combined with open-frame racks of all colors and widths will detract from a professional look and limit the usefulness of space for new or different functions.

Location The location of the MMRs would be outside the computer rooms, in the secure data center space. Placing the MMR on an outside wall is ideal if the space will double as the point of entry so that equipment and workers can go in and out using external doors without disrupting data center operations; just remember to secure the external area with bollards or some other type of protection from vehicle incidents.
Depending on the expected tenant population, though, locating the MMR on an exterior wall and even near a loading dock could be a deal breaker for security reasons.
If your expected tenant population requires significantly more security than normal commercial businesses, the MMR should not act a main point of entry but should instead be placed within the data center, away from external walls.
Although some standards exist, the business uses of the operators and tenants will dictate the type of cross-connect being employed.
Each method has challenges in a colo facility, and each challenge can be met so long as they are identified early and planned for. While not a complete list, the most common connection methods are as follows: Direct connect—Here each carrier connects directly with the client from the carrier-equipment rack in the MMR to the client-side demarcation point or equipment rack, which is also located in a secure half of the MMR see figure, illustration 1.

Drawbacks include higher upfront costs to carriers and operators, who may never connect to every client, and loss of operator cross-connect fees.
In addition, carrier agreements should include adherence to your standards. These standards need to outline access-control, cross-connect, interconnect, and direct-connection means and methods, as well as installation and pathway standards, cable count and color standards, and labeling criteria.
Only permit third-party MMR management companies to have access to both rooms. Make sure this access is authorized, authenticated and audited. Connection Methods — A good cable installer can be assigned to the task of managing the MMR as long as the standards are well documented and SLAs between that company and the operator exist. Pathway Standards — The MMR space above the ceiling is not limitless; as such, controls must be put in place to ensure large and typically unused conduits are not positioned between data connection points.
Traditional cable tray is a sure means of transporting media; most clients will claim that cable trays are an inherent security risk, however.
The use of flexible armored cable is something all operators should consider.
It is lightweight, able to bend and ultra-thin compared with conduit. Color Codes — Color coding the media is a best practice for many reasons. Colors can designate fiber-types, counts, installation dates and specific client connections. Mining out the infrastructure of past clients is easy once the cables are identified, and identification by color is a quick means of disposal.

Designing this zone is extremely important. The two do not mix well for obvious reasons, so designing the EF is key to a successful space.
How do you want to make your MMR secure? Who will be granted access, and at what level will the access be granted? All security measures should be considered at different levels, from IP Cameras to biometrics at room and rack level. There are many options, but the main consideration is that the security fits the profile of the customer services it is protecting.
We should also consider latency.
Minimal connection points improve service; however, not providing managed connection points for the infrastructure will also increase the risk of poor cabling practices and overloading conveyance systems.
This is the homerun versus structured cabling debate which could itself be a whole other blog. Essentially, minimal performance gains can potentially increase downtime in the future due to poor practice and overloading.
This needs clear direction as future refurbishment projects are challenging and time-consuming to complete, i. If we can avoid such projects with good initial design practices then we should strive to do so.
