ENAGAS - Communications and Security team responsible

  • April 2010 - Present (4 years)

Enagas is the Technical Manager of the Spanish Gas System and the main carrier of natural gas in Spain. The work of the company focuses on the transportation of Natural Gas around the Iberian Peninsula, although in recent months the company has launched its horizontal expansion overlooking Latin America. The work environment is critical and we must ensure communication at all times. The company has approximately 1500 employees throughout Spain, in more than forty different locations. And now we have an office in Mexico.

My work in this company ranges from the coordination of the team that keeps the communication network systems and information security, to the launching and implementation of complex and innovative technical projects.

I coordinate a team of ten people, five of them are in charge of maintaining the network, and five of providing infrastructure to the two data centers of the company located in different geographical locations. These data centers are composed of advanced technologies and multi-vendor, but our work is mainly developed with equipment of the leading company in the sector, Cisco Systems. Also, I manage equipment from leading manufacturers in the market such as F5, PaloAlto, CheckPoint, HP, Juniper, BlueCoat, McAfee, etc.

Our primary responsibility and goal is to maintain the network stable and to facilitate the communication between all the employees of Enagas. That permits the normal course of their duties and contributes to them giving additional services to make their work easier. All of this from a point of view completely oriented to the Enagas business. Under our responsibility are critical services such as Email, Internet browsing, the network connection of the remote offices, the information security of the company, phone and video conferencing services, wireless network, etc.

Some of the projects I have done:

  • Implementation of new CPD in Zaragoza
  • Enagas is a company in constant expansion. In 2012, the company decided to build a new data center in Zaragoza to provide redundancy to their most critical services. This project involved the design and interconnection of the network infrastructure required to host services in both active-active data centers. Operated primarily with Cisco technology, implementing innovative protocols like OTV, although using other technologies and manufacturers such as F5, BlueCoat, Juniper, CheckPoint...

  • Core network renewal
  • In 2011 Enagás conducted a technology renewal of all of their network infrastructure in the data center of Madrid. In this project all the old infrastructure was migrated to new Cisco equipment including equipment such as the Cisco Catalyst 6509, Nexus 5548, Nexus 2232PP, 2248 and 2224, FWSM, ACE, WiSM. During the project the necessary migration plans were made to minimize the impact on services.

  • Production environment virtualization
  • Enagas has virtualized their production servers to VMWare technology. We deployed the project usign HP c7000 chassis with Virtual Connect technology, inside of these servers we installed VMware ESX. The connectivity to the VMWare ESX was provided using these Virtual Connect. Subsequently connectivity for virtual environment was provided installing Cisco Nexus 1000v devices.
