I'm working on a solution to better cable my data center cabinets.
Currently: The prior admin ran cabling from the servers to a patch panel at the top of each rack, which then was cabled across the racks to the core. The "patch panel" was just a male to male adapter with marking and created a lot of cabling across the cabinets (1:1 cables). The issue is it takes up a lot of space, runs cabling through racks and creates additional points of failure.
Proposed: At the top of each rack I'd like to setup a X450 with two 10GE ports lagged to my S4 Core. Each x450 doesn't have the density to cover all the ports needs in each cabinet. I'd like to use B5G's for the additional ports. I was thinking to use two stacked B5G's with at least a 2 port lag (2gb) across the stack (1 to each individual B5G). I would then run the server cabling to the top of the rack and run just two fiber links across the racks to the S4 core.
Other considerations: I'm using all equipment we currently have on hand and do not have budget for anything other than adding the 10gb SFP+ ports to my S4 core. And even then...
So my question is does this setup make sense at all? I could increase the lags to 4 from the B5G's to the x450 so I'd have a 4gb connection up to the x450 (verticle), which has a 20gb lag to the S4 (horizontal). Removes the 20-30 CAT5e cables running through the cabinets horizontally as well.
Currently all servers in each rack have a 1gb connection to the S4 but many do not need dedicated 1gb bandwidth.
Guess I'm just looking for a few opinions before I spend several days pulling and re-running cables etc.
