LUN can be mapped to multiple iSCSI Targets to perform storage operations such as read or write.

Manage Hard Disks

tab allows you to monitor the status of the hard disks installed in your Synology NAS, providing
options to manage and analyze hard disk performance and health. To see this tab, go to
click HDD/SSD. For more detailed instructions, please see
Enabling Write Cache Support
Enabling write cache support enhances the performance of your Synology NAS. Only certain hard disk models
support this feature. To ensure data protection while using write cache support, usage of a UPS device is
strongly recommended. We also suggest the system be shut down properly every time after use. Disabling write
cache will reduce the chances of data loss caused by abnormal power outages, but system performance will
decline.
Running S.M.A.R.T. Tests
Disk S.M.A.R.T. tests examine and report the status of your hard disk, alerting you to possible disk failures. We
recommended promptly changing your disk if any errors are detected. S.M.A.R.T. tests can also be scheduled to
run automatically by creating tasks.
Checking Disk Info
The
Disk Info
section displays a hard disk's model name, serial number, firmware version, and total size.
