Description: Cisco UCS lstorage:VirtualDriveDef:readPolicy managed object property
What is cucsLstorageVirtualDriveDefReadPolicy?
This sets the read-ahead behavior for this virtual drive, for example normal, read-ahead, or adaptive read-ahead. An admin selects read-ahead specifically for workloads with sequential access patterns, since pre-fetching upcoming blocks improves throughput there but wastes cache bandwidth on a purely random-access workload like a transactional database. Setting this to read-ahead on a media-streaming virtual drive would let the controller pre-fetch upcoming sequential blocks before they're requested.
Examples
