Are newer, high-density servers too much for older rack cooling technology?

Feb 16, 2021

For problems encountered when renovating data center facilities, to choosing between reducing, reusing or recycling assets, OceanTech offers guidance on the process. We've gathered some helpful tips for frequently asked questions about old servers and data center overhauls.

Today, the power density for fully loaded server racks is 8 kW to 10 kW, with blade systems in the 12 kW to 16 kW range. Aging data centers and server rooms may have difficulty cooling these rack densities, in which case you should run some racks less than full and plan to incorporate new cooling infrastructures in the future.

Older rack cooling technology might not handle higher server density well. In a data center, the cooling system's capability must equal the heat from server density for proper performance; an older system may be inadequately matched to cool higher server densities.  Since vendors are building energy-efficient technology into new server platforms, compute capacity can grow while the cooling system stays the same. But with an increase in rack server density, cooling with traditional technologies such as computer room air conditioners is extremely difficult. Consider data center renovations in order to match rack cooling technology with server density.

How ITAD Reduces Costs

How ITAD Reduces Costs

Large technology companies operate data centers at a scale that’s difficult to imagine, even for those in the industry. New IT assets are what keep these organizations running. On top of the constant need for the latest, cutting-edge hardware, IT leaders in these organizations are keenly aware of the sensitive personal data that will be stored on those assets.

Why ITAD. The legal case

Why ITAD. The legal case

No two companies are exactly alike, so no two companies will have the same motivations to work with an ITAD provider. However, most companies fall into three primary categories: Legal, Ethical/Social, and Economics.
Today we’ll cover the legal reasons for ITAD; the laws that govern privacy and the penalties that follow if you don’t follow them. Most of them will cover data privacy, but there are also environmental laws you should consider.
