Revision as of 12:14, 14 October 2013
Below we propose a design for fiber connections between the Rack Room and the Hall, and network switch and terminal server placement.
- Elliott Wolin, Mark Dalton
- 11-Oct-2013
Notes
- Based on 10**8 photons/sec, 200 kHz trigger rate, existing L1 rejection algorithm, block=1 mode, no compression.
- Ethernet port counts from Fernando's rack layouts and information from Dave Butler concerning other controls requirements.
- We own about 15 24-port managed switches with 10 GBit/s fiber uplinks, some being used in EEL building and other places.
- 8-port managed switches with 1 GBit/s fiber uplinks exist.
- Only managed switches (no hubs!) allowed in hall.
- Fibers come in bundles of 12 or 24, 2 fibers needed for one uplink.
- Standard JLab practice is to terminate all fibers in patch panel when bundles installed.
- Bundle/patch panel installation is expensive, can run much cheaper patch fibers from switch in one rack area to patch panel in nearby rack area.
- DAQ crates require two Ethernet connections each, one for the ROC and one for the fan tray.
- ROC's each need an RS232 connection to a terminal server, terminal servers require an Ethernet connection.
- Each terminal server has xxx ports.
- Need direct fiber link to ROC if max bandwidth > 80 MB/s.
- Switches can uplink 1.25 GBytes/sec.
