Wednesday, 22 March 2006
Agenda:

- 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
- creation of DMZ b/w MCR and SASS firewalls
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.
