The Equinix CH1, CH2, and CH4 data centers are located at 350 East Cermak Rd in Chicago, which is one of the biggest carrier hotels in the world. The building is an unusual confluence of two Interconnection ecosystems, Internet Exchange and Financial Exchange. The two ecosystems create significant demand for space in the building and therefore available colocation space is limited and pricing is higher.
Although Equinix distinctly separates CH1, CH2, and CH4 into separate data centers, but in reality, the sites are in the same building. When Equinix ran out of capacity and expanded to a new floor the company gave the site a new name (ie, CH1, CH2, etc.) The chart below breaks down the sites.
|Site||Location||Gross SqFt||Usable SqFt||Power MW|
Equinix controls and manages conduit to deliver cross-connects between each of their suites in the building. From a cross-connect perspective, Equinix treats CH1, CH2, and CH4 as one large data center. If a carrier is on a different Equinix floor, they are reachable via a standard cross-connect and there are no additional charges to connect within Equinix's site(s) at 350 E Cermak beyond the standard XC fee.
However, it is expensive to connect to networks outside of Equinix space. An Intra-Building Cross Connect (IBCC) is a fiber pair (effectively a cross-connect) that runs from an Equinix suite (A-side) to the building's meet-me room (formerly Telx) on the 2nd floor. The total cost of the pair can be over $1,000 MRC. (IBCCs are at least $750 MRC and there can be Z-end charges as well.)
Equinix connects their Cermak site to Equinix CH3 via IBX Link, which is a lit transport service.
Digital Realty Trust owns the building at 350 Cermak and is Equinix's Landlord. Digital Reality also operates the building Meet Me Room (MMR) on the 2nd floor. The MMR is a legacy Telx facility.
