dptScsiDevWriteMode
Module: DPT-SCSI-MIB
OID (symbolic): DPT-SCSI-MIB::dptScsiDevWriteMode
OID (numeric): 1.3.6.1.4.1.1597.1.4.1.1.33
Node type: OBJECT-TYPE
Type: DeviceWriteMode
Access: read-only
Description: The write modes are Write-back and Write-through, with write-back being the default.
In write-back mode the controller will cache the data and return completion to the host before the data is written to disk. This is the highest performance mode.
In write-through mode the controller will always write the data to disk before posting complete to the host. The data may or may not be placed into the controller's cache.
What is dptScsiDevWriteMode?
Reports whether this device uses write-back (cache the write, acknowledge immediately, higher performance) or write-through (write to disk before acknowledging, safer) caching, with write-back as the default. Switch to write-through if you need maximum data-safety guarantees at the cost of write performance.
