Electromagnetic interference, or radio frequency interference, is when an electromagnetic field interrupts or degrades the normal operation of an electronic device. Such interference is generated on a small scale by everyday items ranging from cellular phones to fluorescent lights. Large sources of interference, such as telecommunication signal facilities, airports, or electrical railways, can interfere with Data Center servers and networking devices if they are in close proximity.
Electromagnetic interference is particularly challenging because it's not always easy to tell that your Data Center devices are being subjected to it. Even when that is known, you may not be able to immediately ascertain what the source of interference is. System administrators, network engineers, and others who work directly with the equipment are most likely to see symptoms first, even if they don't realize their cause. If you learn of a server experiencing unexplained data errors and standard troubleshooting doesn't resolve the problem, check around for possible sources of electromagnetic interference.
If your property is near an identified source of interference, locate the Data Center as far away as possible to limit the effects. All manner of shielding products—coatings, compounds, and metals; meshes, strips, and even metalized fabric—are available to block electromagnetic interference, but most of them are intended for use on individual devices rather than over a large Data Center. Again, distance from the source of interference is the best protection. So, if a Data Center is located twice as far from a source of electromagnetic interference, it receives only 1/4 of the radiation. Likewise, if a Data Center is 10 times as far away, it receives only 1/100.
SISCOM offers innovative technologies to secure data centers from electromagnetic (EM) interference through the following:
1- Environment scanning and gap analysis of data centers standards.
2- Electromagnetic wave simulation and assessment.
3- Measure the EM effect before applying the isolation equipment.
4- Using innovative materials to shape, shield or reflect the EM comes from/to the data centers.
5- Re-test and measure the EM effect after applying the isolation equipment.
