Wednesday, 22 March 2006

Agenda:

  • Status of SLAC/CENIC/ASU/SASS connectivity
    • Schedule for provisioning ASU-SASS local loop
    • Additional H/W needed in the MCR
  • SASS I&T LAN Connectivity
    • System description / justification MSWord
    • Purchase of Firewall / switch / modem
    • DMZ/Telco rack configuration
      • one-off vs. MCR-like
      • UPS sizing
  • MCR location after LAT integration to spacecraft bus.

Attendees:

Bryson Lee, Len Moss, Charles Granieri, Jean-Raymond Pierre, Gary Buhrmaster, Rodney Wong, John Canfield

Discussion:

  • SASS/CENIC link: A telecon is scheduled for Wednesday, 29 March among the various players.
  • Charley provided refined pricing for the Nokia IP380, Checkpoint license, and Cisco 3560G switch
  • Decided to use the same HP enclosure (36U) as the MCR, and install two model 2200RM UPS's with NEMA 5-20P plugs. There are already multiple 120V/20A circuits available at SASS.
  • We recommend that LAT personnel familiar with the I&T flow perform a site survey at SASS. One potential concern is the distance between where the telco/DMZ rack will be positioned, and where the MCR will initially be set up for the post-arrival checkouts. It might be possible to make a fiber, rather than a copper connection between the two racks, if SASS has the necessary infrastructure and the distance is large.
  • We tabled the discussion of potentially relocating the MCR to SLAC after the LAT is integrated on the spacecraft as an idea that's better pursued through the I&T operations folks ( Neil, Ric, Ken Fouts, etc.).

Actions:

  • Gary will prepare a brief memo in advance of the local-loop telecon so everybody's on the same page. He'll try to include some estimate of installation, equipment, and recurring charges for the T3.
  • Bryson will incorporate the updated pricing information into the system-description document.
  • Bryson and Neil will present the system description and justification to Lowell Kleisner / Dick Horne next week to obtain the funding.
  • Rodney / JP / Charley will consolidate the quotes for the various components in preparation for placing the orders.

Wednesday, 15 March 2006

Agenda:

  • Status of SLAC/CENIC/ASU/SASS connectivity
    • Schedule for provisioning ASU-SASS local loop
    • Additional H/W needed in the MCR
  • SASS I&T LAN Connectivity
    • creation of DMZ b/w MCR and SASS firewalls
      • firewall rule changes
      • VLAN changes
    • DMZ host machines(s)
      • quantity & hot/cold spare operation
      • rack space / power / cooling constraints
      • network connectivity (switch ports)
      • console connectivity (KVM ports)
      • purchase lead-time
    • Alternative bidirectional file-transfer possibilities

Attendees:

Bryson Lee, Neil Johnson, Len Moss, Charles Granieri, Jean-Raymond Pierre, Gary Buhrmaster, Rodney Wong, John Canfield

Discussion:

  • Current schedule for LAT arrival at SASS is mid-July; therefore we need to have the necessary equipment in place and tested NLT 15 June.
  • We do not have enough hardware in-house to be able to pre-position and check out connectivity without robbing backup units from the MCR.
  • We do not have enough power / cooling / rack space to install additional equipment in the MCR.
  • Proposed solution is to purchase and configure additional equipment, then deliver it to SASS, do the checkouts, and leave it in place until the LAT arrives. Additional equipment includes:
    • Nokia firewall + Checkpoint license + 48-port switch
    • 2 Dell 1850 servers (DMZ hosts)
    • T3 local-loop interface hardware (TBR)
    • half-height enclosure for above
    • "ITAR" workstations (already on order)
  • Upon arrival of the LAT & MCR from NRL, John C. will unplug the firewall in the MCR from the switch, and plug in the pre-positioned firewall for immediate connectivity to SASS and SLAC.

Actions:

  • Gary will convene a telecon among SLAC, CENIC, ASU, and SASS network engineers to refine the details of the ASU-SASS local-loop connection. Tentatively scheduled for 3/15, may move to early in the week of 3/18.
  • Neil will determine the correct funding mechanism / procedure for the telco charges.
  • Charley will begin preparations to purchase the firewall, license, and switch.
  • Rodney will begin preparations to purchase the additional 1850's.
  • Bryson will assemble a system description and operations concept to provide justification for the additional purchases and define the objectives of the pre-positioning test. Draft due 3/22.
