  1. OVSA Preliminary Design Review Dale E. Gary Professor, Physics, Center for Solar-Terrestrial Research New Jersey Institute of Technology EOVSA ethernet network

  2. Overview of Network Topology Antenna Network Optical Switch Copper Switch Office/Lab Network Connections 10 Gbe Switch OVSA Preliminary Design Review outline

  3. OVSA Preliminary Design Review Network topology • Local copper switch in antenna controller, for LANs in each antenna (100Base-T). • Dedicated optical fiber switch for network between antennas and electronics room (100Base-LX) • Copper switch in electronics room, for rest of network and connection to back-bone (1000Base-T), • ½ T1 line = 768 Mb/s. • 8-port switches for office LANs

  4. OVSA Preliminary Design Review Moxa 4-port unmanaged switch Provides NTP to both cRIO and antenna controller. Provides LAN for fast communication between controller and cRIO. Antenna LAN

  5. Cisco fast ethernet (100 Mb/s) 24-port switch with SFP (small form-factor pluggable) module slots (24 fast ethernet + 2 Gbe). 16 GLC-FE-100LX modules (1310 nm, single-mode) 1 1000Base-T module for connection to copper switch The Cisco SFP modules are $250 each, but can get Cisco-compatible for $80 each. OVSA Preliminary Design Review Fiber switch

  6. Cisco 1 Gb/s 24-port switch with RJ-45 connectors 2 1000Base-T SFP modules, one going to the fiber switch and one going to the OVRO network (½ T1 line = 768 Mb/s) Further fan-out in individual offices and lab, for non-critical systems and VOIP phone system VLANs (virtual LANs) can be set up to provide 1 Gb/s speed of connections between critical systems. If faster connections are needed, a dedicated 10 Gbe connection could be established between two systems. OVSA Preliminary Design Review Copper switch

  7. The offices and labs will have voice (VOIP) and data connections (on separate VLANs). Further fan-out for printers, etc., can be set up via 8-port switches in individual offices. Anything critical should have a dedicated connection to the main copper switch. OVSA Preliminary Design Review Office/lab connections

  8. The correlator will use a 10 Gbe switch to interconnect the F-engines and X-engines, and also to provide one or two ports for connection to the DPP. The size, manufacturer, and model, remain to be determined, based on final design of the correlator in terms of number of ROACH-2s needed. For the prototype, we will not require a switch since there is only one connection needed from the single X-engine board to the proto-DPP. OVSA Preliminary Design Review 10 Gbe switch
