Partitioning the Library
Depending on the height, the number of driv
es and used drive types it’s possible to create up to
4 logical libraries (partitions). The logical libraries also magazine related, this means the number
of available slots are aligned to the magazine borders.
When two half-high drives are installed in a 2U library, the library firmware will support
partitioning in the same way that the 4U supports partitioning with two full-high drives today. The
first partition will contain the first magazine and the first drive. The second partition will contain
the second magazine and the second drive. The mail slot (if configured as I/O) will be shared
between the logical libraries.
7.8.1 Drive naming
When one or more half-high drives are added to a 4U library, the drive naming will change.
Currently, the first full-high drive is "Drive 1" and the second full-high drive is "Drive 2". When
you consider that each full-high drive slot may contain one or two half-high drives, there are four
potential drives in the space that used to occupy two. As a result, the first half-high drive
position, or the first full-high drive position, will be called "Drive 1". The second half-high drive
position will be called "Drive 2". The third half-high drive position, or the second full-high drive
position, will be called "Drive 3". The fourth half-high drive position will be called "Drive 4".
7.8.2 Mixing of drives
The 4U library will support a mix of full-high and half-high drives in the same physical library and
the same logical library. They will support a mix of Gen from different generations (LTO2, LTO3,
LTO4, LTO5, LTO6) in the same physical library and the same logical library. They will also
support a mix of SCSI, SAS, and Fibre Channel in the same physical library and the same
logical library.
Configuration of a 1-Partition-System
Contains any drives present in any drive positions, and it will contain all four magazines. This is
not different than today.
