Hot plugging (also called hot swapping) is the ability to add and remove devices to a computer system while the computer is running and have the operating system automatically recognize the change. This is useful when a system component fails as it enables a new device to be installed without system downtime.

Hot swapping is the term given to the process of replacing a key component of a computer system while it’s still running. Essentially you change a specific part without having to switch it or the whole system off. This enables a business to continue utilising the system without experiencing any kind of downtime.

This may sound like a relatively strange process given that we are all told to power down devices before making changes; but it is highly effective when changing the components a build. 693648-B21 Hot Swap Hard Drive.


Serial Attached SCSI (SAS) is a technology designed to move data to and from computer storage devices such as hard drives and tape drives. It is a point-to-point serial protocol that replaces the parallel SCSI

Serial Attached SCSI (SAS). SAS is the logical evolution of SCSI including its long-established software advantage and the serial physical connection interface. With enterprise storage requirements escalating and becoming more complex factors such as larger capacity greater density security scalability and accessibility are more critical than ever. Serial Attached SCSI (SAS) meets all these demands while providing the highest performance.
