This page provides the information on conventions on IP name and address on the devices routed off the Hall D main Cisco router.

Hall D Internal Networks

Purpose Network VLAN Number of Addresses Broadcast Address
DAQ VLAN 635 256
Controls VLAN 526 512
General VLAN 672 1024
Development VLAN 694 256
Infiniband Local 256

IP Name Conventions

Desktop Computers and Servers

  • Use gluonxx.jlab.org for the online servers main IP addresses. The name comes from GLUex ONline abbreviation. Here xx is a number.
    If we want to keep the same name for Lelvel 3 farm servers, then we will need to use gluonxxx.jlab.org.
  • The additional Ethernet ports will be labeled gluonxx_y.jlab.org for servers with multiple interfaces.
  • We can divide the numbers into ranges for different types of servers, see the table below.
    Note that Level3 is the only one with three digits after "gluon"
  • Use gluonnon-numeric-string.jlab.org for aliases. The character that follows gluon should not be a digit character which would identify this as an alias rather than the main IP address.
Type Name Range
Desktops gluon00 - gluon19
General Purpose Servers gluon20 - gluon39
DAQ EMUs gluon40 - gluon59
Level3 gluon100 - gluon999
Online Aliases gluonnon-numeric-string

Controllers and fan trays for VXS/VME crates

  • Use "rocname" for interface 0 which will be used by the fast DAQ. For instance rocfdc1
  • For the fan trays we can use "vmename". For instance, vmefdc1 .
  • For controls and monitoring we can use interface 1 on the controller called "iocname". For instance, iocfdc1 .

Crate numbering

  • The the fan tray and ROC for any crate will have matching names (e.g. rocfdc1 and vmefdc1 refer to the same crate)
  • The numbering scheme for any detector system will go in order of precedence from North to South then left to right and then from top to bottom. In other words, the first crate in a detector system is the North-most, leftmost, topmost crate for that detector system. The numbers then increase down, then to the right and then to the South. (Left is while facing the front of the crate.)

Embedded devices

  • Continue notation "hallddevice", where device is the name that describes the device type and the number of that device. For instance, hallden2t2.jlab.org or halldbrooks1.jlab.org. Or for High Voltage and Low Voltage devices halldcaen1, halldmpod1, halldcan1. For the main file server we can use halldfs1, and for fast the RAID file servers we can use halldraid1, halldraid2.

Crate Names

  • Each major detector component will have a number of crates named based on its GlueX name, followed by one or two digits specifying the number of the crate.
  • If more than one detector component is a part of one crate only one name is assigned, preferably of the larger one or a name that can characterize both detectors, e.g. use "tagx" for TAGM&TAGH crates.
  • Numbering assignment with respect to the geographical location (the map) will need to be created out before requesting IP names. The map should define one-to-one corresponds between this detector-based scheme and one based on the geographical location ordering of the crates in the racks and the Hall.
  • The VME crates with the JLab discriminators are separated from the other VXS crates, they are considered as a separate "detector" for the naming purposes.
