Facility Infrastructure and Capacity

The University has leased a caged area in CHR with a capacity to house forty (40) racks. All colocation space in CHR is allocated by DIT based upon a model using 24” X 48” 42 U racks. Although CHR is equipped with multiple and redundant Uninterruptible Power Supply (UPS) units, generators, and cooling infrastructure for reliability purposes, CHR does not guarantee a defined level of uptime. Unscheduled outages are possible, and scheduled outages might be required periodically for maintenance or upgrade purposes. 


Terms and cost of Occupancy

The University has a five-year occupancy contract with CHR, which runs from 12/01/2019 through 12/01/2024. The Occupant accepts financial responsibility from the date CHR services become available to the Occupant until the end date of the contract. The option to terminate the contract will be available to the Occupant at the date of contract expiration or renewal between the University and CHR. Changes in the scope of occupancy, and the corresponding change in occupancy cost, can only be made upon mutual agreement between the Occupant and the University.

DIT will serve as the administrative Point of Contact between the Occupant, the University, and CHR. Space and service allocations, both initial and additional, must be requested via the online using the Colocation Service Request Form. DIT reserves the right to deny any initial requests and requests for expansion while recommending alternate solutions.

All costs charged by the University to the Occupant are based upon a sustainable cost-recovery model. The signatories of this MOU will collectively facilitate the monthly payment transaction process at the time of occupancy. All costs and transactions incurred in the move and installation of equipment are the responsibility of the Occupant unless stipulated between all involved parties outside the scope of this MOU.  

Scope of occupancy is defined by physical footprint in terms of racks and rack units (U). Thirty (30) U or more up to 38 U defines one full rack (DIT reserves the top four U for networking if needed). The annual price for a rack is $2,800 ($233.33 monthly) for power density up to 5kVA. A physical footprint of 29 U or less is priced at $77 per U annually ($6.48 monthly). Racks that are reserved for future use are billed immediately upon signing this MOU, regardless of actual usage. Occupants are billed monthly. Funds are automatically transferred out of the designated KFS on the 15th day of each month.

Network one-time and ongoing fees are as follows:


Facility access and use

As part of the request, approval, and occupancy process, detailed personnel information will be provided on the Colocation Request Form regarding who will need access to CHR. DIT will facilitate the initial access approval process with CHR on behalf of the Occupant. Once the Occupant is in the CHR system, she/he/they may access CHR without DIT intervention. CHR access is available 24x7x365.


Facility oversight and communications

CHR monitors the facility 24x7, including power, cooling, and physical security. DIT monitors network connectivity to the DIT-owned network switches. Occupants monitor their own switches and systems. DIT maintains a listserv for communications with all Occupants. DIT functions as the communication Point of Contact between CHR and the Occupant. It is the obligation of the Occupant to ensure that DIT is provided with up-to-date contact information from their colleges, departments, and units.


Oversight and management of IT systems

Oversight and management of all hardware and software in the facility is the responsibility of the Occupant. DIT does not support, maintain, or administer systems owned by Occupants. DIT will assist in troubleshooting problems related to the equipment upon request. DIT manages and supports all DIT-owned and provided network switches.

Primary ownership of planning and implementing occupancy rests with the Occupant. DIT supports physical occupancy and network connectivity through collaboration in planning the move and installation, assistance in hardware transport from the facility loading dock onward, infrastructure resource assignments, and rack and cable management.



DIT will take responsibility for any equipment damaged through the negligence of DIT staff. DIT is not liable for equipment damage related to the facility infrastructure or any actions beyond the control of DIT personnel. 


Use of CHR and DIT managed space and equipment

CHR offers wireless access to all Occupants. Office space is also available for use on a short term first-come, first-served basis. All hardware delivered to CHR must be scheduled in advance with DIT. Equipment must be unpacked in the loading dock/staging area, transported to the cage space, and racked as a single exercise. No boxes, cardboard, and transport materials are permitted in the data center. General cleanliness and courtesy are expected. 


Security and acceptable use of the facility and equipment

Access to CHR is managed 24x7 by CHR security staff. Access is not transferable from one Occupant to another; however, guests can accompany an authorized Occupant following CHR security guidelines. Since the cage space is used by DIT as well as other Occupants, it is the responsibility of each Occupant to ensure that their personnel does not interfere with the operation of other equipment. Occupants are not permitted to use or interact with network, power, and cooling infrastructure outside of their own racks. Access under the raised floor and over the drop ceiling is prohibited.

The cage in CHR is accessible only to authorized University of Maryland colocation occupants, DIT support staff, authorized and accompanied guests or contractors, and CHR staff. The Occupant is responsible for determining whether cage level security is acceptable based on their compute mission and data classification. Rack-level security (locks) are mandatory. Occupants will have access to their racks via a DIT administered key management system.
