6.10.2 Viewing SMART Information for a Drive Self-Monitoring, Analysis, and Reporting Technology (SMART) is a monitoring system for computer hard disks to detect and report on various indicators of reliability, with the hope of anticipating failures. With SMART, a hard disk's integrated controller works with various sensors to monitor various aspects of the drive's performance, determines from this information if the drive is behaving normally or not, and makes available status information to software that probes the drive and look at it. The xStack Storage Array collects the SMART information and displays it on the management console in tow collections. This information consists of: SMART data that serves as a summary of the overall status. SMART attributes that are defined differently by each vendor. To view SMART information for a drive, select a drive under Blade A Base Pool in the Logical Resources or on the Physical Resources tab. You can then use the second tab to view information collected from the SMART data (see Figure 6-11). You may notice a slight delay, as the xStack Storage Array polls this information from the drive (SMART data is polled from the drive every 10 seconds). The third tab displays the SMART attributes in a table (see Figure 6-12). Again, you may notice a slight delay, as the information is polled from the drive (the displayed information refreshes every 10 seconds).

Monitoring the xStack Storage
6.10.2
Viewing SMART Information for a Drive
Self-Monitoring, Analysis, and Reporting Technology (SMART) is a monitoring system for computer
hard disks to detect and report on various indicators of reliability, with the hope of anticipating
failures. With SMART, a hard disk's integrated controller works with various sensors to monitor
various aspects of the drive's performance, determines from this information if the drive is
behaving normally or not, and makes available status information to software that probes the
drive and look at it.
The xStack Storage Array collects the SMART information and displays it on the management
console in tow collections. This information consists of:
°
SMART data that serves as a summary of the overall status.
°
SMART attributes that are defined differently by each vendor.
To view SMART information for a drive, select a drive under
Blade A Base Pool
in the
Logical
Resources
or on the
Physical Resources
tab. You can then use the second tab to view information
collected from the SMART data (see Figure 6-11). You may notice a slight delay, as the xStack
Storage Array polls this information from the drive (SMART data is polled from the drive every 10
seconds). The third tab displays the SMART attributes in a table (see Figure 6-12). Again, you may
notice a slight delay, as the information is polled from the drive (the displayed information
refreshes every 10 seconds).
