The Storage Performance Development Kit (SPDK) provides a set of tools and
|
|
|
|
|
libraries for writing high performance, scalable, user-mode storage
|
|
|
|
|
applications. It achieves high performance by moving all of the necessary
|
|
|
|
|
drivers into userspace and operating in a polled mode instead of relying on
|
|
|
|
|
interrupts, which avoids kernel context switches and eliminates interrupt
|
|
|
|
|
handling overhead.
