Create Switch Metadata CSV

This page provides directions on constructing the switch_metadata.csv file.

Prerequisites

  • The SHCD file for the system.

    Check the description for component names while mapping names between the SHCD and the switch_metadata.csv file. See Component Names (xnames).

Overview

This file is manually created to include information about all spine, LeafBMC, CDU, and leaf switches in the system. None of the Slingshot switches for the HSN should be included in this file.

The file should have the following format, in ascending order by component name (xname):

Switch Xname,Type,Brand
d0w1,CDU,Dell
d0w2,CDU,Dell
x3000c0w38,LeafBMC,Dell
x3000c0w36,LeafBMC,Dell
x3000c0h33s1,Spine,Mellanox
x3000c0h34s1,Spine,Mellanox

The above file would lead to this pairing between component name and hostname:

Hostname Component Name
sw-spine-001 x3000c0h33s1
sw-spine-002 x3000c0h34s1
sw-LeafBMC-001 x3000c0w38
sw-LeafBMC-002 x3000c0w36
sw-cdu-001 d0w1
sw-cdu-002 d0w2

The hostnames are automatically generated in ascending order by switch type.

Switch brands

The general guidelines for any abbreviations are that MLNX or MLX is for Mellanox and DL is for Dell. All other switches are HPE Aruba switches.

The brand name of the management switches can be determined from one of two places:

Device Diagrams tab

The Device Diagrams or River Device Diagrams tab of the SHCD has pictures and diagrams of the components of the system including the management network switches. This will have a long name which shows the part number and the vendor name.

Rack Layout tab

The Rack Layout or River Rack Layout tab shows the part number in the context of its location within the cabinet.

Part Number Brand
Aruba 8320 48P 1G/10GBASE-T and 6P 40G QSFP with X472 (JL481A) Aruba
Aruba 8325-23C 32-port 100G QSFP+/QSFP28 (JL627A) Aruba
CS-XGE40-MLNX-2100-16 Mellanox
HPE Aruba 6300M - switch - 48 ports - managed - rack-mountable Aruba
JL625A - Aruba 8325-48Y8C BF 6 F 2 PS Bdl Aruba
XC-XGE-48P-DL2 Ethernet switch (Dell S3048-ON) Dell
XC-XGT-48P-DL2 Ethernet switch (Dell S4048-ON) Dell

Format

Spine and leaf switches use the format xXcChHsS. LeafBMC switches use xXcCwW. CDU switches use dDwW.

Directions

  1. Identify the switches in the SHCD.

    Look for the following:

    • The slot numbers for the LeafBMC switches (usually 48-port switches)

      • In the above diagram this is x3000u22

    • The slot numbers for the spine switches

      • In the above diagram these are x3000u23R and x3000u23L (two side-by-side switches)
      • Newer side-by-side switches use slot numbers of s1 and s2 instead of R and L

  2. Each spine or leaf switch will follow this format: xXcChHsS:

    This format also applies to CDU switches that are in a River cabinet that make connections to an adjacent Hill cabinet.

    • xX : where X is the River cabinet identification number (the figure above is 3000).
    • cC : where C is the chassis identification number.
      • If the switch is within an air-cooled cabinet, then this should be 0.
      • If the switch is within an air-cooled chassis in an EX2500 cabinet, then this should be 4.
    • hH : where H is the slot number in the cabinet (height).
    • sS : where S is the horizontal space number.

  3. Each LeafBMC switch will follow this format: xXcCwW:

    • xX : where X is the River cabinet identification number (the figure above is 3000).
    • cC : where C is the chassis identification number.
      • If the switch is within an air-cooled cabinet, then this should be 0.
      • If the switch is within an air-cooled chassis in an EX2500 cabinet, then this should be 4.
    • wW : where W is the slot number in the cabinet (height).

  4. Each CDU switch will follow this format: dDwW:

    If a CDU switch is in a River cabinet, then follow the naming convention in earlier “spine or leaf switch” step instead.

    • dD : where D is the Coolant Distribution Unit (CDU)
    • wW : where W is the management switch in a CDU

  5. Each line in the file must specify the type: leaf, CDU, LeafBMC, or Spine.

  6. Each line in the file must specify the brand: Dell, Mellanox, or Aruba.

  7. Create the switch_metadata.csv file with this information.

    See the example files in the next section for reference.

Examples of switch_metadata.csv

Example: Two Aruba CDU switches, two Aruba LeafBMC switches, four Aruba leaf switches, and two Aruba spine switches:

Switch Xname,Type,Brand
d0w1,CDU,Aruba
d0w2,CDU,Aruba
x3000c0w31,LeafBMC,Aruba
x3000c0w32,LeafBMC,Aruba
x3000c0h33s1,leaf,Aruba
x3000c0h34s1,leaf,Aruba
x3000c0h35s1,leaf,Aruba
x3000c0h36s1,leaf,Aruba
x3000c0h37s1,Spine,Aruba
x3000c0h38s1,Spine,Aruba

Example: Two Dell CDU switches, two Dell LeafBMC switches, and two Mellanox spine switches:

Switch Xname,Type,Brand
d0w1,CDU,Dell
d0w2,CDU,Dell
x3000c0w36,LeafBMC,Dell
x3000c0w38,LeafBMC,Dell
x3000c0h33s1,Spine,Mellanox
x3000c0h34s1,Spine,Mellanox

Example: Two Dell LeafBMC switches and two Mellanox switches in the same slot number:

Switch Xname,Type,Brand
x3000c0w38,LeafBMC,Dell
x3000c0w36,LeafBMC,Dell
x3000c0h33s1,Spine,Mellanox
x3000c0h33s2,Spine,Mellanox
