Network Topology

ChivaNet's primary Internet connection is provided by a T1/DS1 line carrying an MPLS link to the CoreSite LA1 data center in Los Angeles, California. This resilient circuit is protected by a 4-hour SLA.

We have a second Internet connection served by Comcast Business, at 300Mbit/s symmetric.

We host our own authoritative DNS servers on-premises at our 1DCA facility (see https://datashed.tech/wiki for more information on this facility)

Local equipment includes:

  • Edge Router: Cisco 3845
  • Access Server: Cisco 3845 with 2 analog modem boards
  • Core Router: Cisco 7204VXR
  • Core Switch: Cisco Catalyst 6506 with 2x Sup32 supervisors in a redundant configuration
  • In-Rack Access Switches: Arista DCS-7050S-64 48-port 10G
  • Servers:
    • Oracle SPARC T4-1 (database)
    • Sun Fire T2000 (DNS)
    • Dell/EMC PowerEdge R730 (virtualization)
    • HP ProLiant DL360 gen10 (3x) (virtualization)

    • IBM System x3650 M3 (Fibre Channel SAN)
    • Brocade SilkWorm 200e (Fibre Channel Switch)



Power Infrastructure

We use CyberPower and PowerWare rackmount UPSes for power conditioning and backup power, and APC smart power distribution units. The local electric utility is exceptionally robust, and power outages are rare, and generally do not significantly impact availability.

Grid power is supplemented by 33 photovoltaic panels connected through microinverters to a networked Enphase monitoring system.

You can see current power usage at https://power.datashed.tech/.



HVAC

The 1DCA facility is cooled by a 4-ton air conditioning unit, with a supplemental fresh air intake/exhaust system that reduces HVAC system load during the colder months. The two elements of the HVAC system are automatically switched by an in-house hardware and software solution called FACON (FAcilities CONsole), which has several temperature and humidity probes monitoring interior and exterior conditions, and automates the selection of HVAC and fresh air.

FACON monitoring will alert 1DCA operators in cases of an exceptional thermal condition.
