a2PhysicalSectorSizeInBytes
Module: MYLEXDAC960SCSIRAIDCONTROLLER-MIB
OID (symbolic): MYLEXDAC960SCSIRAIDCONTROLLER-MIB::a2PhysicalSectorSizeInBytes
OID (numeric): 1.3.6.1.4.1.1608.3.2.1.2.1.13
Node type: OBJECT-TYPE
Type: DmiInteger
Access: read-only
Description: Physical Sector Size in Bytes (Default: 512 bytes).
What is a2PhysicalSectorSizeInBytes?
This read-only value reports the physical sector size in bytes of the underlying disks, with the MIB noting 512 bytes as the typical default, distinct from a2LogicalSectorSizeInBytes which is what's presented to the OS. A mismatch between logical and physical sector sizes can matter for performance tuning on 4K-native drives.
