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

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.

Subsystem DAQ Systems

During installation and long down times, individual detect groups may wish to run dedicated DAQ systems without the hassle of constant coordination with other detector groups. During these times, the following computers are assigned for detector groups to prevent interference.

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, iocpulser1 .

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 gluonfs1, and for fast the RAID file servers we can use gluonraid1, gluonraid2.

Crates

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.

Crate Control Module IP Addresses

IP addresses for ECAL crates

Translation Table

(n.b. the IP address for the ROCs is 129.57.135.rocid)
(for the ioc* hosts, the IP address for the controllers is 129.57.26.(1-256))

Infiniband Switch

The switch has a built in webserver for administration and diagnostics at:

http://halld-ibsw-1.jlab.org

Login using the classic "german-esque" online password. (If you do not know this, check with Dave A.)

n.b. Feb. 16, 2016 -- There were some ports that were registering continuous "symbol errors". This actually caused gluon104 to perform about 10 times slower. The ports for gluon104, gluon110, and gluon49(landed) were switched from ports 8, 7, and 29 respectively to the ones listed in the table above. The issue with gluon110 and gluon49 was noticed via the orange arrow lights on the back of the switch. (They should normally be green.)
