Abstract

With the application of the Institutional Technical Reserve for Connectivity of previous years, important improvements were made to the institutional Data Center as the complete replacement of the air conditioning system, with the installation of new precision in-row appliances, the replacement of the raised floor, with the use steel plates with cellular concrete filling, the replacement of the partitions with masonry walls, changing the doors, replacing the ceiling covering by flameproof plates and LED fixtures. The installation of two new redundant air conditioning unit stook up the space of one rack each. However, the removal of evaporators from the deactivated air conditioning system in an adjoining room, separated by dry-wall, allowed the expansion of the Data Center in six more racks, as soon as a new expansion is necessary. This allowed the maintenance of ideal temperatures of functioning, with the devices operating alternately in 99.9%to optimize energy consumption and conserve the entire system. In addition, the planned internal confinement for the Data Center with doors that secrete the air from the cold aisle and promote air circulation between the two hot aisles increased the overall thermal efficiency of the system, maintaining the more stable temperature; allowing switching between the two devices without greater imbalances between hot corridors and greater energy savings. With the adjustments made in the Data Center area, the teams of support and infrastructure were brought together in a single environment, with comfort air conditioning units in a Network Operations Center – NOC where monitoring of links, services, servers, information about the system support to the Data Center such as the operation of UPS and air conditioning can be monitored by professionals and related by cause and effect, including in response to user call openings and phone calls. Another aspect observed is that with an increase in the processing in 2018, the provision of new services; the increment of document storage systems and other teaching media research and assistance (classes, documents, videos and image diagnostics, among others); increased monitoring of services and transaction logs forced an increase in of primary storage capacity, the acquisition of secondary storage that it will still be insufficient to meet future demands. The current storage park already exceeds 500Tb gross and should triple in 3 years, with the current main storage of research and computational environment (VMs) for the same purpose already has eight years of use and is no longer supported by the manufacturer, thus making it susceptible to electrical and mechanical problems inherent in the time of use in operation.
