virtualDiskReadPolicy
Module: ArrayManager-MIB
OID (symbolic): ArrayManager-MIB::virtualDiskReadPolicy
OID (numeric): 1.3.6.1.4.1.674.10893.1.1.140.1.1.11
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Indicates whether the controller's read cache will be used when reading from a virtual disk. Note: Virtual Disks on a PV660F do not have a read cache policy. Possible values: 1: Enabled - Read Ahead 2: Disabled - No Read Ahead 3: Adaptive Read Ahead
What is virtualDiskReadPolicy?
Shows how the controller's read-ahead caching behaves for this virtual disk: always reading ahead, never reading ahead, or adaptively switching based on access patterns, which affects sequential-read performance. The source notes that virtual disks on a PV660F controller don't support a read cache policy at all.
