In some instances it may. However, this is going to depend on a few factors. TIA-942 is pretty specific about running all of your cabling accommodating growth so that you don't have to revisit these areas. This is true regardless of the type of server. There are a few reasons for this and a few reasons that you want to do this. First, you are going to get better pricing on a project basis. Second, anytime you do moves, adds and changes you run the risk of harming what already exists. Third, you lose a significant amount of air when you remove floor tiles. And lastly, you really don't want to be changing cabling or cabinets, realistically, you will change out your hardware. The cabling lasts about 10-15 years depending on the company and the standards. You may have several versions of servers in the cabinet in that same time. So you should install a quantity of cable that would support either the blade chassis or regular 1u servers. Generally you want to allow for 4 cables per server if you are using primary and secondary network connections and in-band and out of band management.
Does anyone know if deploying blade servers will decrease my cable count?
