Strategies for Deploying Blade Servers in Existing Data Centers
Blade servers have a major advantage over traditional ones@improving processing ability while using less power per server. But, with their smaller footprint

fan cooling  There are some effective fan assist devices that couple to the rack; these are described in greater detail in APC White paper #42, Ten Steps to Solving Cooling Problems Caused by High Density Server Deployment . Isolating racks. Isolating racks away from rows in an area open on all sides is sometimes used in an attempt to reduce the density in an area and to allow more vented floor tiles to be associated with a rack. However, this approach allows hot exhaust air to return around the sides of the rack to Read More...
Dell's 8-CPU Intel Servers Increasing Its Enterprise Focus

An Improved Architecture for High-efficiency, High-density Data Centers
Globally, data center power and cooling infrastructure wastes more than 60 million megawatt-hours per year that do not contribute usefully to powering IT

fan cooling  power is going to fan and humidification. This is a factor of four reduction in loss. The above chart was developed assuming a chilled water design, tier 4 design, 3-foot raised floor for the room cooling solution, and an average power of 10kW per rack. This data is only for the CRAH unit and does not include the chiller, pumps, and cooling tower. These devices can be studied separately or combined with the CRAH to obtain the overall cooling efficiency of the data center. Note that the chiller and Read More...

Deploying High-density Zones in a Low-density Data Center
New power and cooling technology allows for a simple and rapid deployment of self-contained high-density zones within an existing or new low-density data center

fan cooling  each rack, requiring extra fan power. In addition, if there is no raised floor there can be substantial mixing of the cool supply air with warm exhaust air in the room, which will require lowering the supply temperature far below what is needed at the IT racks. Hot spots can force lowering the supply temperature even further to control overheating. Too-low supply temperature can risk condensation on the cooling coil, which results in wasteful dehumidification-rehumidification and reduction of system Read More...
The Advantages of Using Hardware-based TCP Fan-out for High-Performance Messaging
Multicast-based messaging systems are limited in use to point applications under very controlled conditions due to their tight coupling to the Layer 2 network

fan cooling  of Using Hardware-based TCP Fan-out for High-Performance Messaging Multicast-based messaging systems are limited in use to point applications under very controlled conditions due to their tight coupling to the Layer 2 network, lack of management and control, and lack of robustness. This white paper explores the key disadvantages of multicast, and explains the benefits of a hardware-based solution with embedded support for point-to-point ‘unicast’ distribution and message routing.

fan cooling  I am an avid fan of the cinema. I get my business and leadership knowledge from reading articles. Books on politics capture my attention. I am an advocate of equality, which implies that unjust inequalities disturb me. The most recent book I read was Robert Reich’s Aftershock , which describes the 2008 economic global meltdown and its current effects. Regarding my favorite place on earth, since I travel extensively for SAS, I will reply with my standard “which country do you like best?” answer. It Read More...

However, the native storage virtualization capabilities shipped with VMware ESX Server do not provide the same benefits and hardware reductions as those seen in the server space. Many customers have experienced an increase in storage requirements after implementing their virtual infrastructure. The reasons for this increase are many, including but not limited to a requirement for a shared storage Read More...
