The following information provides technical staff with detail regarding requirements,
restrictions, and recommendations for co-location of equipment.
Rack Related Information/Requirements
Due to limited space, the Research Data Center must restrict installations
to rack-mounted hardware. Standard rack space will be made available by OIT
at a cost based on the amount of rack space consumed. (# of U’s). Units
may provide their own racks providing they comply with the standards outlined
below.
Exceptions to standard racks or rack-mounted equipment require explicit approval
from the RDC Advisory Board.
- Dimensions: 42u standard computer racks or racks whose
dimensions are roughly 82”H x 24”W x 42”D (or smaller).
These racks are short enough to fit through most doorways, are narrow enough
to fit on one tile, and have a depth that won’t complicate service areas
for other racks.
- Networking: The top 4U in each rack requiring network connections
should be left empty for the installation of networking equipment. (See Network
Related Information for more specifics.)
- Console Access: Groups supplying their own racks should
plan to also supply console/remote management access as needed.
- Weight: Rack weights should be less than 1500 lbs. (loaded).
Weights over 1500 lbs. should be distributed across multiple racks.
- Air Distribution/Cooling: Most racks now cool from the
front and exhaust through the back. The room will have a “hot aisle/cold
aisle” design where cool air coming from below the floor will be forced
up the front of the racks in “cool” aisles. There are a number
of means for cooling within racks and these are left largely to the rack owner
except that if hot air is vented out of the front of the rack, special accommodations
may be necessary.
- Rack Power: Circuits for racks will be ordered through
Facilities Management and may require 4-6 weeks of lead time. OIT will try
to make available some standard circuits (typically 30A/120V) to avoid lead
time and expedite installation. Other configurations can be accommodated but
will require a specific order. In-rack UPS systems can be accommodated and
are encouraged.
- Rack Doors: Provided they do not cause problems for other
racks, there are no specific door requirements.
Network Related Information/Requirements
The following describes the network within the Research Data Center. Special/additional
network deployments may be possible.
- Network Layout: Network switches will be located outside
of the Research Data Center facility. OIT will deploy networking from the
switches to patch-panels located within racks. Wiring will be category 6.
As the need for 10G service arises we will address it on a case by case basis.
- Network Connections: Connections from the patch-panels
to the equipment will be coordinated on a case by case basis between OIT and
the equipment owner. Wiring runs must be ordered and may require 4-6 week
lead time. OIT will try to keep some network connections on hand to avoid
lead time.
- Patch Panels: Networking will be isolated for each installation
so that groups will not have to share patch panels. Panels can be run for
up to 6, 7-12, or up to 24 connections. Costs for the panels and wiring will
be figured into the rack installation costs. Rack owners are encouraged to
anticipate future needs at time of installation as additional wiring into
a rack can be disruptive to its operation.
- Subnets: The Research Data Center will be on its own subnet(s).
Greater isolation can be accommodated if required.
- Extension of Other Building Subnets: The extension of
other building subnets into the Research Data Center cannot be accommodated.
The current campus network architecture does not allow for it.
- Data Rate: Transmission speed is up to 1GB (10/100/1000).
This is direct from the network switch to the server.
- Latency: Latency is expected to be very minimal (less
than 1ms).
