Infrastructure

Teide supercomputer is a general purpose High Performance Computing infrasctructure. It is composed of 1100 Fujitsu computer servers, with a total of 17800 computing cores and 36 TB of memory, a high-performance network and a parallel system of NetApp storage. Managed by the Instituto Tecnológico y de Energías Renovables (Institute of Technology and Renewable Energies), Teide supercomputer  is housed in D-ALiX datacenter which provides high available electrical and cooling infrastructure, and high speed internet connectivity.

Compute nodes

The core of the compute nodes are FUJITSU PRIMERGY CX250 S1 servers. These servers feature the latest in Intel Sandy Bridge processors, allowing to obtain not only the best performance but also a great energy efficiency. The CX250 servers are housed in multi-node PRIMERGY CX400 chassis in a ratio of 4 CX250 nodes per CX400 chassis.

Sandy bridge Platforms

The computing core of the infrastructure is formed by 1028 nodes with Intel Sandy Bridge processors:

  • Two Intel Xeon E5-2670 processors with 8 cores / 16 T @ 2,60 GHz 16 MB
  • 32 GB RAM DDR-3 1600
  • 500GB HDD
  • Advanced remote management
  • 2 Gigabit ethernet ports
  • 1 IB QDR enhanced port

Ivy bridge Platforms

72 Ivy Bridge processor technology are also available:

  • Two Intel Xeon E5-2670v2 with 10 cores / 20 T @ 2,60 GHz 16 MB
  • 32 GB RAM DDR-3 1600
  • 500GB HDD
  • Advanced remote management
  • 2 Gigabit ethernet ports
  • 1 IB QDR enhanced port

Fat nodes

There is a fat node platform formed by three FUJITSU PRIMERGY RX500 servers with the following hardware setup:

  • Four Intel Xeon E5-4620 processors with 8 cores / 16 T @ 2,20 GHz 16 MB
  • 256 GB RAM DDR-3 1600
  • 2 300GB HDD in RAID 1
  • Advanced remote management
  • 4 Gigabit ethernet ports
  • 1 IB QDR enhanced port

Storage

The storage solution is based on NetApp technology and fulfills a dual purpose, on the one hand meet all technical requirements for supercomputing solution and secondly ensure high degree of flexibility. The main features of this system are:

  • 500TB net
  • The storage array is configured in cluster mode having all the redundant elements to deal with potential hardware failure.
  • Two types of disk
    • SAS : The fast disks are configured using 24 expansion trays SAS interface drives with 450GB drives and working at 15KRPM.
    • SATA: Slow disks are configured using 24 expansion trays SAS interface drives with 3TB disks working at 7.5KRPM.
  • To improve the overall performance of read operations on SATA disks, the system has 512GB FlashCache memory per node, which perform the automatic caching of the most accessed data blocks.
  • It is considered the RAID-DPTM (double parity) use for all RAID groups. RAID groups are grouped into "Aggregates" stripping the information to optimize the performance and safety. Each RAID-DP group is sized to reach a configuration with 14 data disks and 2 parity.
  • There are a set of global spare disks according to best practices.

Networking

Teide-HPC networking solution relays on a four networks topology, each one with a specific purpuose. Three networks are based on ethernet technology and are used for Out-Of-Band management, on band management and storage access. The fourth network is an Infiniband technology one, used to inter-node communication in parallel processing.

Connectivity

Two login nodes are provided to give users access to Teide-HPC infrastructure, this nodes allow the use of the scheduling system. There are also two transfer nodes which permit high speed data transfers accesing to the data network backbone.

Teide Supercomputer is conected to internet through the Spanish academic and research network, Rediris, with a 10 Gb link.

Proyecto ALiX

Proyecto Alix (Alix Project) is a Council of Tenerife proposal which has been led by the Instituto Tecnológico y de Energías Renovables (Technological Institute of Renewable Energy), ITER SA Its main objective is to improve the competitiveness of the ICT sector in the Canary Islands, which is conducted through its three pillars:

  • D-ALiX. Datacenter ALiX project. Placement services and offers a competitive offer massive external communications.
  • Canalink. Responsible for laying and launched a neutral submarine cable system.
  • IT3. Responsible for the deployment of a terrestrial fiber optic ring island in Tenerife.

RedIris

RedIRIS is the Spanish academic and research network that provides advanced communication services to the scientific community and national universities. It is funded by the Ministry of Economy and Competitiveness and is included in the Ministry's map of Special Scientific and Technological Facilities (ICTS). It is managed by the Public Corporate Entity Red.es, which reports to the Ministry of Industry, Energy and Tourism.
