The "Hard Disk Performance" function periodically tests the read/write speed (MB/s) of hard disks or file systems (Filesystem) to understand Disk I/O performance. If the monitored target's test value is lower than, nonexistent, or higher than the alert value, an alert message will be issued.


Introduction to Server Storage System Architecture
➢Local hard disk: Includes options for RAID architecture or RAM Disk
➢Remote storage system mount: Can mount other hosts or dedicated storage systems (such as NAS, SAN) to meet different application needs

I/O Read/Write Performance Test
For the I/O read/write performance of the server storage system, we mainly evaluate the read/write rate per second (MB/sec), and test targets include file systems or disk partitions.

Key to System Performance: Disk I/O
In addition to CPU and memory, Disk I/O performance is also a crucial factor affecting the overall performance of the server. When users or application systems experience slow speeds or data processing delays, optimizing hard disk performance becomes an essential strategy.

Factors Affecting Disk I/O Performance
➢Frequent program writes
➢Insufficient cache memory buffer capacity of RAID controller cards
➢Poor network speed of mounted storage systems
➢Low Disk IOPS
➢Ongoing disk array rebuild operations

Importance of Monitoring Hard Disk Performance
By regularly testing the read/write speed (MB/s) of hard disks or file systems, we can accurately grasp Disk I/O performance. In case of abnormal detection values, timely warnings can be issued, enabling operations personnel to conduct in-depth analysis using this data and effectively prevent more serious problems.
