Cabling for Large configurations

Rack to Rack connections between Visio pages

  • With front view you can have up to six racks per page
  • With rear view you can have only up to two racks per page
  • If your solution includes more than two racks you will have to split your rear view drawing over two or more pages
  • In that case you might have to run cables from one page to another in rear view
  • I made an additional shape “ Rack to Rack 24 port rear“ for running cables between pages, L/R variants

Example: Rack-to-Rack connect shape

rack_to_rack_left

Usage:

  • Can run 12 cable pairs
  • Use ports 13-24 for running cables between adjacent pages
    • Node4&3 page to Node2&1 page
  • Use ports 1-12 if you have skip one page in order to reach your destination page
    • Node6&5 page to Node2&1 page
    • Cables passing trough Node4&3 page
  • Show me quote with more than six racks and I will be happy build a 48 port version of the shape 🙂

Example: “Rack to Rack 24 port R” shape

rack_to_rack_example1

  • Location of “Rack to Rack 24 port R” shape
    • Top right corner of drawing, just in side the margin shape
  • Cables running toward racks located on pages to the right

Example:”Rack to Rack 24 port L” shape

rack_to_rack_example2

  • Location of “Rack to Rack 24 port L” shape
    • Top left corner of drawing, just in side the margin shape
  • Cables running toward racks located on pages to the left
  • 10 GbE Netapp cables terminating in a switch on this page
  • 1GbE Mgmt cables passing this page to following page

Example use case 1:

rack_to_rack_example3

  • Initial setup:
    • two nodes in one rack
    • Cluster interconnect & management switches in the same rack as controllers
    • Additional rack with disk shelves
  • Expansion
    • Additional two nodes + disks in one rack
    • Additional rack with disk shelves
  • You have to run Cluster Interconnect and management cables for new nodes to another page with switches
  • Four Racks total on two separate rear view pages

Example use case 2:

rack_to_rack_example4.png

  • Six Rack Example
  • 2 Nodes / Rack pair
  • Cluster Interconnect in Rack 3
  • Management Switches in Racks 2

Using switch shapes in multi-page drawings

  • You can use Mid mounted switch boxes to assign ports from switches that are not located with the same pages as originating ports
  • Reserve ports by cabling both ends of cable shape to same port
    • This way the cable is just “End Shape” with “Zero Legs”
  • Sometimes you can just use these to reserve ports and skip running cables between pages
    • if you decide skip running cables between pages, reserve ports with “Zero Legs” cables both in controller and switch ports
