Implementação de um modelo de estrutura de rede para laboratório de alto desempenho em bioinformática

Abstract

Bioinformatics has become an area of utmost importance since its inception in the search for solutions focused on the biological nature of life. With the exponential advancement in the data generation of countless equipments as new generation sequencers, it is necessary a computational system connected in a network, which can provide necessary support for the analysis, study and manipulation of data acquired from various technologies aimed at the areas of molecular biology , biochemistry, genetics, among others. To this end, in this work, a network infrastructure solution was proposed that can serve as a basis for anyone proposing to build or deploy an infrastructure for use in the bioinformatics area. Following the most modern technological criteria and concepts on the market, a hierarchical model with two layers with redundant intermediate systems was proposed. The access layer has two link layer switches and the collapsed core layer has two multilayer switches organized in a redundancy system. This laboratory will be divided into five work sectors, with the Data Center hosting two computational process servers, a data backup server and storage for storage. The departments will be inserted in different VLANs in order to separate the broadcast domains. To avoid layer two loops, the Spanning-Tree Protocol (STP) was used. To maximize the performance of multi-layer switches, EtherChannel technology was used through the link aggregation control protocol (LACP), and for routing between VLANs, the EIGRP protocol. The security policy was to disable ports, secure passwords, sticky security with restricted ports for a MAC and access control lists for external control. It was concluded that the physical and logical topological structure used, together with the chosen services and protocols, supply the basic needs for a small laboratory for recurring activities in the area of bioinformatics.
