I've been asked to layout a "Best Design" for our wiring situation in our server racks. The datacenter is already in use and this is a 24/7 environment with downtime schedules tough to come by. With that said, I will only get 1 shot at completing the design and work. What I'm looking for are some suggestions, things to keep in mind, and hopefully document stencils that I could use for the proposal.
The 2 datacenters are drastically different at this time.
The first uses cat walks for wires and all direct cable runs for Cat5 and Fiber. This server room is an absolute mess. There are many cables hanging that are no longer in use, intertwined with active cables. The fiber is grouped together, but is not distinctly segregated from the rest of the cables nor is it properly protected. Power cables are run aside other cables and some cable management is used. This room is more of an issue since the only way I can foresee improving it is to completely re-wire it.
The second is fairly new and has raised floors with cable trays. It has 11 rows of racks ranging from 4-8 racks per row. Each rack has a patch panel near the base and has individual power distribution per rack. The power is located toward the bottom, front of the rack.
a) most of the servers have redundant power
b) every server has at least 1 cat 5 network cable, 1 KVM dongle connected to cat 5, and 1 power cable
c) some servers have 2 network cables, 1 kvm dongle and cat 5 cable to it, 1-2 power cables, and at least 1 fiber connection.
So any good suggestions or things you’ve done in the past to make for a clean rack would be a great help. Also, any ideas about how to keep it clean after the installation would be great as well.
Thank you in advance.
