Blade servers: small in size, big on energy costs

Today’s blade servers are not directly related to virtualization but are often considered since the concept involves several kind of consolidation (physical, logical, partitioning, etc.).

Blade servers, which are deemed the next big thing in hardware, are also a big energy drain in an enterprise, according to a recent study that looks at the latest advances in server technology.

The results of the study by TheInfoPro (TIP) Inc., a New York research firm, reveal that these new server technologies have not provided heating and cooling advantages. TIP recently released the second half of a server study it conducted in 2005. The research examined the concerns of 133 server professionals.

Despite their intense heat production, the slim servers are indeed a priority for IT managers. According to TIP’s survey, 62% of the respondents said they will spend more money on blade servers in the next year.

Gill said blade vendors are realizing that excess power is a problem in terms of energy efficiency, and there is an initiative among them to create blades that are more energy-efficient. A number of groups have suggested that vendors should develop a standard for measuring energy efficiency and then develop technology accordingly. He also noted that virtualization technology would alleviate some problems with power efficiency and consolidation…
