Which of the following is TRUE about WAFL?

WAFL, which stands for Write Anywhere File Layout, is a file system specifically designed for use with NetApp storage systems. The statement that WAFL organizes blocks of data into files and stores metadata in Inodes is true because WAFL functions by allocating disk space dynamically, allowing data to be written in an optimized manner. It efficiently organizes the data blocks and maintains file system integrity by using Inodes to store metadata, which includes information like file size, ownership, and data block locations.

This organization facilitates fast access and management of storage resources, ensuring that data retrieval and integrity checks can be performed efficiently. WAFL's design is particularly well-suited for environments where performance and reliability are critical, such as enterprise data centers.

The other options describe aspects that do not reflect the true nature of WAFL. For instance, WAFL is not a protocol, nor is it limited to SSDs; it is a file system that functions across various types of storage media. Additionally, WAFL does utilize Inodes to manage metadata, which is contrary to what is stated in one of the wrong options.
