University Data Center: Frequently Asked Questions


Question: How much of the university’s overall server population can fit in the UDC?

Answer: That’s difficult to say, but historical growth patterns suggest there is sufficient capacity for the entirety of the university's computing footprint.  As current customers evaluate what they want to move, they find they have many options that can reduce the server and data storage footprint on campus through central services like the Virtual Machine Gateway (UT-VMG), Database Hosting, and Austin Disk; or cloud services such as Amazon Web Services (AWS) and UT Box.  Often, departments can also retire aging switches and other old network equipment where the data center provides that functionality in top-of-rack switches.


Question: What is the life expectancy of the UDC?

Answer: In general, the physical life expectancy of a data center building is different from its useful life expectancy as a data center. The latter will be dependent on the university’s computer utilization, growth and power requirements for newer server technology.

The building is designed for redundancy to allow proper maintenance to take place, which will extend its useful life. The majority of facilities on campus operate in a “run-until-fail” mode. You can’t take equipment offline, so you plan for its inevitable failure. Our building isn’t like that. It is designed to allow concurrent maintenance without affecting uptime.



Question: What kind of equipment can go into the UDC?

Answer: The West Hall and East Hall are designed to accommodate 19” rack-mountable devices. There is only a limited amount of space for non-rack-mountable equipment. There are also some hardware configuration issues that can affect whether equipment can achieve the full service levels. Please see UDC System Standards for a complete description.


Question: How often will you do maintenance on the power and network?

Answer: Typically network maintenance is performed at least twice a year and can be more frequent depending on network needs. Power maintenance is performed routinely and is dictated by each component’s specific requirements. All planned maintenance will be scheduled ahead of time and customers will be given advance notice through approved communication channels such as email distribution lists and the UT ServiceNow Alerts & Outages page.


Question: How do I request access to the facility to get to my servers?

Answer: To request building / Data Center access to the facility, submit a UDC Support request.


To support easier server management, there is a dedicated remote management network that will allow administrators to remotely access their servers as needed. The UDC operators are also available 24x7x365 to perform tasks like power cycling. Customers can call the UDC operations staff at (512) 471-0007.


Question: What if a server goes down a vendor must provide onsite emergency maintenance?

Answer: Customers should submit a UDC Support request and call the UDC operations staff at (512) 471-0007 and inform them that the vendor is expected. Operators are available on a 24x7x365 basis.


Question: What support is available to prepare servers for the redundant network?

Answer: Network connectivity is provided from A and B sources to every server for redundancy. Each server equipped with dual network interface cards (NICs) is connected redundantly to both the A and B sides of the network via the top of rack switches. Servers can go down during scheduled maintenance and unplanned events if servers are redundantly connected but not properly configured to use the network equipment using link aggregation control protocol (LACP) bonding.



Question: What is the cost to move my servers to UDC?

Answer: Rates are now based on space and are a flat $270 per Rack Unit (RU) annually.  Equipment that does not meet prescribed UDC System Standards may incur an additional one-time setup fee.


Question: My grant already includes an overhead amount that is paid to the university. Shouldn’t the co-location fee be covered by that?

Answer: Because the dynamics for individual award agreements vary, and the degree to which individual deans distribute returned overhead to principle investigators in their units varies, for all questions about how your grant- specific costs relate to co-location services and fees, please submit a UDC Consulting request.
