5.2.1 Partition granularity

Partition granularity refers to the smallest unit of the components making up a partition.
The names that indicate granularity include SB, IOU, DU and PCI_Box. The following table lists the partition
granularity of the components that constitute a partition.

SB partition granularity
The partition granularity of the SB is one physical SB.
IOU partition granularity
The partition granularity of the IOU is one physical IOU.
DU partition granularity
The partition granularity of the DU is a physical DU divided in two. Since four HDDs can be installed in each
physical DU, the partition granularity of the DU is two HDDs.

IOU#3
PCI_Box partition granularity
PCI_Box partition granularity is a physical PCI_Box divided into two. The partition granularity of the PCI_Box
is called the PCI_Box LH. The PCI_Box LH is a PCI_Box divided into two.
One PCI_Box LH can be connected to one IOU. The PCI_Box LH belongs to the connected IOU. In other
words, the PCI_Box LH is incorporated in the partition to which the connected IOU belongs. The connection
between IOU can PCI_Box is optional. For details, see
