What do you mean by EMC?
Ans: EMC stands for Electromagnetic compatibility, which enables various electronic devices to work without the use of mutual interference. EMC establishes the bridge between electrical and electronic equipment in the electromagnetic environment. All electronic devices are very potential devices to emit different electromagnetic fields. This also helps to limit the unintentional generations, propagation, and operates without the need for mutual interfaces.

Some storage controllers also support LUN Masking.

Ans:
What is LUN Masking and why we need it?
Ans: LUN is a Logical unit number, which offers an authorized process available for some host. LUN can be implemented at the HBA level (HOST bus adapter).
The purpose of using LUN masking is to write volume labels at the windows based servers, and also renders the LUN mask system unusable by any other operating system and reduces the data loss.
