It has been pretty standard practice when installing new communications cabling to leave the old cabling in place because it is costly and time-consuming to remove. Abandoned cable, however, creates a significant fire hazard. In fact, the National Electrical Code now requires the removal of accessible portions. The problem is not the copper wire but the plastic insulation and jacket. These can create the same fuel load as gasoline. When heated, the plastic can release gasses, which can stop respiration or blind. Another issue is the lead content in the jacket, which can be ten percent by weight. When the PVC in the jacket breaks down, it releases lead dust, which then blows around the facility. Once the abandoned cable has been removed, remember to minimize the amount which ends up in a landfill or incinerated by recycling as much of the plastic and metal it contains as possible.
Looking to improve the efficiency of your data center? Virtualization is one option that more data center operators are considering. Virtualization is a process that reduces the number of servers in a data center by combining the jobs several servers do onto one.
Virtualization might seem like an IT matter, but for ultimate success, facilities departments should play a role in the process. Some questions facility executives should ask:
Have the old servers been removed? One potential pitfall is that a data center moves to virtualization, but some old servers are left running.
Assuming the old servers have been removed, has the chiller and fan output been adjusted for the new heat load? Less servers means less heat, which should allow for cooling savings.
Finally, what about incentives? Some utilities, such as Pacific Gas and Electric, offer incentives for server virtualization. Such incentives typically need to be applied for before starting a virtualization project.
To make efficient use of available daylighting, choose a ceiling panel with a high light reflectance rating. If a ceiling can reflect most daylight back into a space, the amount of artificial lighting can be decreased, saving you money. LR-1 rated panels reflect the most daylight back into a space — 75 percent or more. LR-2 and LR-3 rated panels do not reflect as much light and may not be suited for spaces where daylight maximization is a goal.
