Whisper V2 15U 600mm(W) x 1000mm(D) Soundproof rack

The Whisper V2 (WSP2-15U-610) is a 15U – 1066mm high active sound-proof server rack, 600mm wide x 1000mm deep, with an internal usable depth of 895mm.

Whisper V2 Soundproof racks (racks) are designed and manufactured to reduce the unacceptable levels of noise from servers by up to 40dBA*. The Whisper rack's acoustic design incorporates ultra quiet fans, barrier soundproof foam & sealed doors. As a result Whisper rack is a real alternative to building server rooms / closets; since IT equipment like servers and network switches can now be located in general office space.

The original Whisper rack proved both successful and popular. Building on the experience we have made a number of changes. The new V2 is much quieter and encourages front to back cooling, something server manufacturers strongly recommend.

Most alternative acoustic racks are much larger then expected, taking up valuable room space. Some racks cannot be sited with the back close to a wall since they have back-mounted fans. This also means that the rack cannot be placed in a corner, often where most people want it. The Whisper V2, does not have any of these limitations. The Whisper is no deeper or wider than a standard rack and, due to the ultra-quiet vertical airflow, can be placed in any corner out of the way.

The decibel (dB) is a logarithmic unit, for example, an increase of 3 dB is a doubling of the "strength" of the sound, an increase of 10dB means that the sound is 10 times as loud; i.e., 70 dB is 10 times as loud as 60 dB."

Most people are not familiar with Acoustics, therefore we have tried to explain below what you can expect in simple terms. For detailed explanation on Acoustics and Decibels please see http://en.wikipedia.org/wiki/Decibel_(Acoustics)

Examples of sound levels in common environments:

74dBA = Fully populated blade server running at 80% load

60dBA = Average Server

60dBA = Normal conversation

55dBA = Background noise in an average office

35dBA = A quiet library

Whisper V2 – Noise reduction results:

The chart below shows results from tests that we carried out on the Whisper V2. You will notice that significant reductions are achieved. A 40.5dBA reduction was achieved when tested with a source noise of 90dBA, however most applications do not have such a loud source. 

Looking at a fully populated blade server which was tested the noise level was reduced from 74dBA to 45.2dBA. As 45.2dBA is less than background noise is an average office, the server noise will go unnoticed and will no longer be intrusive. No other acoustic soundproof rack at this price can keep noise level below “background noise in an average office” for the spectrum of sound source that we used for testing.

Still not sure ?

We are happy to provide a demonstration of the Whisper V2 capabilities at our Slough offices. You may wish to bring a sound recording of your server or the actual server itself.
