5.8 Partitioning the Library
Depending on the height, the number of drives and used drive types it’s possible to create up to 4
logical libraries (partitions). The logical libraries are 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.
5.8.1
Drive naming
One full-high drive is "Drive 1". When using half-high drives, the first half-high drive position will be
called "Drive 1", The second half-high drive position will be called "Drive 2.
5.8.2
Mixing of drives
The 2U library will support a mix of drives from different generations (LTO2, LTO3, LTO) 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.
