SSD TRIM
If a volume consists entirely of SSDs (Solid State Drives), we recommend enabling SSD TRIM. This feature
optimizes the read and write performance of volumes created on SSDs, increasing efficiency as well as
extending the lifetime of your SSDs.
Before trying to set up SSD TRIM, please see DSM Help for detailed instructions and more limitations.
Note:
SSD TRIM is only available on certain Synology NAS models and RAID types.
Some SSD models are not able to perform SSD TRIM on RAID 5 and RAID 6 volumes. Please refer to the
compatibility list at www.synology.com.
Manage iSCSI LUNs
iSCSI is an Internet Protocol based storage networking standard for linking data storage facilities. iSCSI
facilitates data transfer over local area networks (LANs), wide area networks (WANs), or the Internet. By mapping
iSCSI Targets and iSCSI LUNs, client servers can access space on a storage server as if it were a local disk.
iSCSI LUN Types
Synology NAS currently supports the following types of iSCSI LUNs:
iSCSI LUN (Regular Files): This type of iSCSI LUN is created by designating a portion of a volume. It may be
later expanded as needed. This type of iSCSI LUN provides flexibility of dynamic capacity management with
Thin Provisioning.
iSCSI LUN (Block-Level): This type of iSCSI LUN is created on a RAID Group and provides flexibility of
dynamic capacity management in addition to optimized access performance. You can expand this type of
iSCSI LUN later using unallocated space on the RAID Group.
Create, Edit, or Remove iSCSI LUNs
You can manage iSCSI LUNs by going to Main Menu > Storage Manager > iSCSI LUN. For detailed
instructions regarding how to create, modify, or remove iSCSI LUNs, please refer to DSM Help.
