5 Hours of Coverage, Response Times & Escalation

For all requests, the ITS goal is to have a staff member assigned and acknowledge requests within 4 business hours of receipt. Campus priorities may require exceptions to this goal during certain times of the Academic year.

5.1 Hours of Coverage

The Data Center Services are provided 24 hours a day seven days a week except for periods of planned maintenance.

5.5 Other Requests

Requests for service features and functions not yet implemented can be submitted to the ITS Support Center though the online ticket system, SlugHub.

6 Maintenance and Service Changes

Some Data Center Services have pre-scheduled maintenance windows (which are superseded by campus-wide change-restricted days, as noted on the ITS Maintenance Calendar). Most maintenance will not impact service; in the event that maintenance is expected to result in a service outage, ITS will provide at least two weeks’ notice. These pre-scheduled maintenance windows are listed on the Data Center service web pages and on the ITS Maintenance Calendar.

See the ITS and Campus SLA for details of our standard maintenance and service process.

7 Pricing

Some Data Center Services are provided without charge to customers through IU funding. For other services, ITS covers the costs relating to these services in order to encourage members of the UCSC community to use the central computing facilities and to take advantage of the secure and power-protected environment. These include the following services:

  • Physical Server Hosting
  • Private Cloud Computing in the UCSC Data Center, using Joyent (when fully self-managed)
  • 24x7 Data Center Operations
  • Campus Active Directory (AD) - file storage and sharing, authentication, printing
  • Kerberos Authentication
  • Storage - AFS storage for students, faculty, and staff, accessible through the Unix timeshare, NFS storage for servers managed by the DCO Unix team

For Cloud Computing through AWS, services are arranged on behalf of the customer; costs are passed through without mark-up.

Other Data Center Services are provided through individual arrangement with customers, and recharge rates (or cost pass-through) apply. This includes the following services:

  • Virtual Hosting in the UCSC Data Center
  • Managed Services (including server administration)
  • Data Backup and Recovery

Data Center Billing

For customers who arrange for recharge or pass-through services, charges will be billed at the close of each month in the Pinnacle billing system, then transferred to FIS Banner. Questions regarding billing or specific charges should be sent via email to

Data Center Recharge Methodology

The total annual recharge estimate is a combination of known fixed costs and projections of variable costs. While the actual time spent providing Managed Services (which include systems administration) can vary from month to month, support hours are calculated by averaging annual support and normalizing support over a three- to four-year period. The method enables consistent budgeting and avoids cost spikes when major system enhancements or replacements take place.

Due to a general-fund offset provided by the campus, Managed Services (including systems administration) are provided at a reduced rate, and physical-server hosting services are provided at no cost. These funding offsets are intended to encourage campus departments to use the Data Center rather than departmental space to host their servers and applications, since the Data Center provides a secure and reliable environment.

Some Data Center charges (e.g. backups) are calculated using actual consumption of the service, and as a result these charges vary each month.

In some cases, departments provided a permanent transfer of funds to ITS for their services. In such cases, these funds are reflected as funding offsets on the monthly billing statement, and are used to reduce the overall monthly recharge.

For each recharge service, a rate packet is submitted to the Campus Direct Costing Committee containing all applicable templates. More information is available here: UCSC Recharge Rates
