Gluster file system supports different types of volumes based on the requirements. Some volumes are good for scaling storage size, some for improving performance and some for both. 1. Distributed Glusterfs Volume – This is the default glusterfs volume i.e, while…

Disk Performance Basics

Input/output operations per second or IOPS (IO/s), throughput (MB/s or MiB/s), and response time (ms) are the common performance measurements for storage devices, such disk drives or RAID sets. IOPS measure is generally used to describe storage device capability for handling random small block (4 – 8 KB in size) input-output (IO) requests that are typical for on-line transaction processing…
