Figure 5-7. Extents Tab (Advanced View) 5.3.3 Viewing SMART Data and Attributes (SMART Data and SMART Attributes Tabs) Self-Monitoring, Analysis, and Reporting Technology (SMART) is a monitoring system for SATA drives to detect and report on various indicators of reliability, with the hope of anticipating failures. SMART is not supported on SAS drives. With SMART, a SATA 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 primary array collects the SMART information and displays it on the following read-only tabs:  Smart Data. Shows SMART overview, self-test, and offline data collection information for a SATA drive (see Figure 5-8).  Smart Attributes. Shows SMART attributes that are defined differently by each vendor (see Figure 5-9). SMART is supported on SATA drives only, not on SAS drives. The use of SATA drives is not recommended because they cannot be used in High Availability configurations. 78 Chapter 5 Managing Physical Storage

Viewing SMART Data and Attributes (SMART Data and SMART Attributes Tabs)
Self-Monitoring, Analysis, and Reporting Technology (SMART) is a monitoring system for SATA
drives to detect and report on various indicators of reliability, with the hope of anticipating
failures. SMART is not supported on SAS drives. With SMART, a SATA 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 primary array collects the SMART information and displays it on the
following read-only tabs:
Smart Data
. Shows SMART overview, self-test, and offline data collection information
for a SATA drive (see Figure 5-8).
Smart Attributes
. Shows SMART attributes that are defined differently by each vendor
(see Figure 5-9).
SMART is supported on SATA drives only, not on SAS drives.
The use of SATA drives is not recommended because they cannot be used in
High Availability configurations.
