Comments

We're planning to tentatively test the waters with UMD/EMI by installing a supplimentary cream CE with it, however like our peers we'd rather let the dust settle for a bit and only swap over when the benefits outweight the risks.

Topic: Protected_Site_networking

• Both the local user and grid site are on separate, routable subnets
  
• The Tier-2 is actually split across two, the "Grid" and the "HEC".
  
• The Tier-2 is further split between a private and public VLANs.
  
• There is a 10G backbone to the Tier 2 network.
  
• There is a 1-Gb dedicated light path from the Tier-2 to RAL, and we also share the University's link to Janet (although I believe we are capped at 1Gb/s).
  
• All switches are managed by ISS. We have access to the University Cacti pages.
