Indicates the supported LBA data size. The value is reported in terms of a power of two (2^n). A value smaller than 9 (for example, 512 bytes) is not supported. If the reported value is 0h, then the LBA format is not supported or is used. DUMMYSTRUCTNAME.RP Indicates the relativ...

LBA是一个整数,通过转换成 CHS 格式完成磁盘具体寻址 ATA-1规范中定义了28位寻址模式,以每扇区512位组来计算,ATA-1所定义的28位LBA上限达到128 GiB。2002年ATA-6规范采用48位LBA,同样以每扇区512位组计算容量上限可达128 Petabytes 由于CHS寻址方式的寻址空间在大概8GB以内,所以在磁盘容量小于大概8GB时,可以使用CH...

■ Oracle 6.4 TB NVMe SSD should be formatted using a label of type EFI (format -e command). Ensure that when the EFI label is created by ZFS, the default start sector is 256, which aligns S1 with 128k (if the block size is 512). The vtoc label default cylinder size is 50176 (...
