Description: Cisco UCS storage:LocalDisk:physicalBlockSize managed object property
What is cucsStorageLocalDiskPhysicalBlockSize?
This OID reports the physical, as opposed to logical, block size of this local disk. An admin distinguishes physical from logical block size when troubleshooting performance issues on drives that use a larger physical sector size internally while presenting a smaller logical one, since misalignment there can hurt write performance. If a drive shows unexpectedly poor write performance, an admin would compare this physical block size against the logical block size to check for a sector-alignment mismatch.
