Computer Systems

The IMSE-CNM IT infrastructure was established to support research, development and innovation in the design and testing of integrated circuits, and to help the Institute control its lab equipment and other general-purpose applications more efficiently. Structured as several virtual local networks (VLAN) with different security features and levels, it is capable of supporting all the different design tools and services available at the Institute.

    Research Network
    This network comprises a set of Solaris servers, storage systems and user terminals which facilitate implementation of the Institute’s various activities, and a Linux cluster system for accelerating the different stages in the integrated circuit design process. More specifically, its features include:
  - A central Sun server plus four Solaris-based departmental servers
  - A Linux cluster made up of 15 RedHat-based units
  - Workstations, PCs and Sun Ray network terminals
  - A disk storage system and a backup tape library
  Virtualized Services Network
    This network is based on an IBM BladeCenter virtualization system comprising four Blade servers, and features:
  - Windows Applications
  - Long Term Storage
  - Remote Access Interface
  - Support computer rooms
  Laboratory Network
    This network connects the general purpose computers installed in the Institute’s different laboratories which are used for data acquisition tasks, control, instrumentation and the automation of test processes. It also includes lab instrumentation with operating systems and communication interfaces similar to those of conventional computers such as:
  - PCs
  - Logic Analyzers
  - Modular Analysis Systems
  - Wave Generators
  - Arbitrary Function Generators
  - Oscilloscopes
  Administrative Services Network
    This network comprises two application servers in a redundant configuration and eight clients. It supports the management programs, databases and office applications used by the Institute’s administrative services.
  Demilitarized Zone (DMZ)
    This is the perimeter network made up of all the systems and services requiring access from outside the building:
  - Web server
  - Email Server
  - VPN access server
  - System for training sessions corresponding to the Master in Microelectronics
Networking and Communications

IMSE's IT Support Unit administers and manages local area network and IP address routing completely autonomously. As a research center belonging to the CSIC (Spanish National Research Council), the IMSE connects to the Internet through the CICA (Scientific Computer Centre of Andalusia) via a dedicated, 1 Gb/s fiberoptic link.
The network is based on Twisted Pair cabling, shielded in certain areas of the laboratories and, gathered together in communications racks on each floor. It supports a local area network of more than 400 connection points, all of which support speeds of up to 1 Gb/s.
The IMSE also provides primary network services for the Centro Andaluz de Biología Molecular y Medicina Regenerativa (CABIMER - Andalusian Center for Molecular Biology and Regenerative Medicine) and to the Estación Biológica de Doñana (EBD - Doñana Biological Station).

    Wi-Fi network
    To provide access to systems with wireless interfaces and support Fast Ethernet connections with the computers on the communications network, 6 access points have been installed. These connections are also available through the Eduroam network, thus further facilitating mobility for wireless users.
  Internet access
    The computer network connecting IMSE-CNM to the other CSIC institutes located in the vicinity and to the whole Spanish R&D network (RedIRIS) operates via two fiber-optic connections. One of these links the CSIC centers in Cartuja directly to CICA while the other connects the CSIC centers to the Universidad de Sevilla network.
  VPN access
    To increase the security level of the IMSE computer network, a mechanism has been put in place to remotely access the IMSE-CNM via a virtual private network (VPN) using personal digital certificates.
    As an alternative to conventional telephone communications, an IP based telephony solution has been installed. This solution, besides offering a wide range of integrated services, takes full advantage of the building's infrastructure by sharing voice and data communications on the same wiring system.
