Atlas DBs and online network

A wiki page for the discussion on how to connect Atlas online (pit) to the DB services in IT

A few acronyms

  • ATCN: ATLAS control network, the online network
    • ATCN is propagated via a fiber to the computer room
    • Switch D513-C-IPY-SHP3M-10 on RAC2 is used to associate DB servers to ATCN
  • GPN: CERN general public network
    • This is the network used by all IT services including monitor and backup
  • ONLINE: db nodes for atlas online RAC
  • OFFLINE: db nodes for atlas offline RAC

Tentative Network Diagram

atonr_network.gif

  • ONLINE:
    • connected to ATCN
    • connected to OFFLINE (only) via private network (non-routed)
    • not connected to GPN

  • OFFLINE:
    • connected to GPN
    • connected to ONLINE via private network (non-routed)
    • not connected to ATCN

  • GATEWAY:
    • bastion host, used to access ATCN from GPN

PS: Cluster interconnects can be ignored for this purpose.

Open points

  • How to access (and grant access) to(from) a series of services on GPN is needed for DB operations
    • Backup: Tivoli (access to TSM servers)
    • DBA custom monitoring
    • Oracle EM
    • Lemon and other 'sysadmin' monitoring
    • Quattor
