  1. Portuguese Grid Infrastruture(s) Gonçalo Borges Jornadas LIP 2010 Braga, Janeiro 2010

  2. Portuguese EGEE Infrastructure 8 Sites LIP-Lisboa, LIP-Coimbra NCG-INGRID-PT UPorto (3 clusters) UMINHO-CP, DI-UMINHO IEETA CFP-IST Resources 2500 job slots Hundrends of Terabytes for Storage space Support for more than 20 VOs WLCG,EGEE, EELA INGRID, IBERGRID 2

  3. RCTS • 10 Gbps link between Lisbon and Porto • ~ 1 Gbps to other important regions • Important improvements are foreseen • Better International high speed connectivity • New links through Spain are (almost) operational • Minho and Galicia • Spanish Estremadura •  5 Gbps • Better Geant connectivity • Better redundancy • Ring between both countries 5 Gpbs 5 Gpbs

  4. INGRID overview INGRID:Iniciativa National GRID Push for resource sharing in Portugal Follows the path of EGI Helps to fulfill the Portuguese responsibilities in the framework of present European Projects EGEE, WLCG, IBERGRID... INGRID Management Commitee: FCT, UMIC and LIP (technical coordination) Steps towards INGRID deployment... Selection of 13 pilot applications HEP, Weather Forecast, Civil Protection, ... Deploy a dedicated data centre to host resources Located in Lisbon @ LNEC Works as the INGRID seed / core infrastructure 4

  5. Facilities @ INGRID main node Computer room area 370m2 85 cm raised floor Electrical power: 1st step:1000 kVA 2nd step 2000 kVA Protected power 5x UPS 200kVA Diesel generator Chilled water cooling: Chillers with free-cooling (2x375kW) Close-control units (6x150kW+47kW) Fire detection Very Early Warning Smoke Detection Fire extinction being installed 5

  6. Different VLANs: Scalability, Security, Easier Management Inbound/Outbound traffic to the grid local farm via 2 linux boxes FW/NAT servers connected to the central switch at 10 Gbps. Network @ INGRID main node Vlan Grid Cluster Vlan Routers Vlan Support Services FW/NAT 1 Vlan ISCSI Arrays Vlan Site Services FW/NAT 2 Central 10 Gigabit Ethernet switch Vlan Core Services Vlan User Services FW 10 Gbps LIP-Lisbon + LIP-Coimbra Internet 3.5 Gbps 6

  7. Topology @ INGRID main node Computing Blade Centres SGE cluster ... Firewall Core 10gigabit Ethernet switch Support Services Blade Centres net ... Storage = Lustre + StoRM 7

  8. Core Services Fault Tolerance Redundant services distributed between 2 blade centres Solution based on Xen Virtual machines Xen images available Storage accessible via Internet SCSI (iSCSI) Controlled by OCFS2 shared cluster file system... guaranties full data coherence and data integrity in simultaneous data accesses from multiply hosts ISCSI ARRAY 1 12 x 1TB SATA disks Raids 10, 6 LUNS 2 x 512 MB iSCSI controllers Blade centre ... OCFS2 Filesystem Xen Images Repository ISCSI ARRAY 6 12 x 1TB SATA disks Raids 10, 6 LUNS Blade centre 2 x 512 MB iSCSI controllers Central 10 Gigabit Ethernet switch 8

  9.
