The workload type that describes I/O sizes for read and write operations that areless than or equal to 16 KBwhile file sizes are10 MB or moreisRandom. In Nutanix Files, workload types are used to optimize share performance based on I/O patterns. Small I/O sizes (≤16 KB) indicate a random access pattern, as opposed to sequential, even if the files themselves are large (≥10 MB). This is common in workloads like databases or virtual desktops, where small, non-contiguous I/O operations are performed on larger files.
TheNutanix Unified Storage Administration (NUSA)course states, “A Random workload type in Nutanix Files is characterized by small I/O sizes, typically 16 KB or less, regardless of file size, as it reflects random access patterns rather than sequential ones.” The Random workload type optimizes the share for such patterns by adjusting caching, prefetching, and data placement to handle frequent small I/O operations efficiently, even when the files are large.
TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “workloads with I/O sizes of 16 KB or less, even on large files (e.g., 10 MB or more), are classified as Random, as the small I/O size indicates non-sequential access patterns.” Large file sizes do not necessarily imply sequential I/O; the I/O size itself determines the workload type, and 16 KB or less is typical of random access.
The other options are incorrect:
Sequential: Sequential workloads involve larger I/O sizes (typically >64 KB) and contiguous access patterns, such as those seen in media streaming or backups, not small I/O sizes like 16 KB or less.
Asynchronous: Asynchronous is not a workload type in Nutanix Files; it may refer to replication or I/O handling methods but is not relevant here.
Default: The Default workload type applies a balanced configuration but does not specifically optimize for small I/O sizes like the Random type does.
The NUSA course documentation emphasizes that “I/O sizes of 16 KB or less, even with large file sizes, indicate a Random workload type in Nutanix Files, ensuring optimal performance for random access patterns.”
