Low Medium High
Likelihood
Heating, air conditioning, and air quality failures are medium-likelihood, medium to high-impact
events because they are dependent on electrical power. Any power failure in the Willis Library
building or the surrounding region could shut down environmental systems in the Digital
Libraries Division offices. Local or regional power failures may shut down systems at the UNT
System Data Center at the UNT Discovery Park research campus (the off-site server facility).
Temporary environmental problems that affect human comfort may disrupt the administration of
the repository but should not lead to service outages or data loss. In the case of a long-term
disrupt in power to the server room cooling system, Lib-TACO will shutdown systems so that
they do not overheat and suffer permanent damage. Extended cooling problems could lead to
service outages. Prolonged outages are low-likelihood (not illustrated).
Management Strategy
The Digital Libraries Division depends on facilities management provided by the UNT Libraries
and UNT Facilities. Lib-TACO monitors and manages environmental conditions in the UNT
Libraries' server room.
The Digital Libraries Division and Lib-TACO carry out regular backup of data, databases, and
applications according to standard backup practices. These backups are intended to serve as
the basis for restoration of server infrastructure materials in the event of data corruption or loss.
Data stored as part of the UNT Libraries' Coda repository is migrated between two storage
facilities, one in the Willis Library, and one in the UNT System Data Center at the UNT
Discovery Park research campus.
Lib-TACO operates a redundant cooling infrastructure in the UNT Libraries' server room. There
is adequate capacity to operate the cooling systems in the event that one should fail because of
mechanical or electrical issues.
Upgrades and expansion to existing server room cooling infrastructure is in the
planning/implementation process as part of a Willis Library Mechanical Electric and Plumbing
(MEP) refresh scheduled for 2015-2016.
