that used to occupy two. As a result, the first half height drive position, or the firstfull-high drive position, will be called "Drive 1". The second half height driveposition will be called "Drive 2". The third half height drive position, or the secondfull height drive position, will be called "Drive 3". The fourth half height driveposition will be called "Drive 4".Important: In a 4U library a full height drive sled may be installed in drive slot 1(drive will occupy slot 1 and slot 2) or drive slot 3 (drive will occupyslot 3 and slot 4). A full height drive sled should never be installed indrive slot 2 (drive will occupy slot 2 and slot 3).Mixing of DrivesThe library will support a mix of full height and half height drives in the samephysical library and the same logical library. They will support a mix of Gen 3,Gen 4, and Gen 5 drives 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 physicallibrary and the same logical library; however, mixing drive interface types in thesame logical library is not recommended.Configuration of a 1 - Partition SystemA one partition system configured for a 4U library contains any and all drivespresent in any drive positions, and it will contain all four magazines.When configured with one logical partition, the Element Address assignments willbe as follows:v DTE assignments will be as shown in Figure A-1.v STE assignments will be as shown in Figure A-4 on page A-6.Configuration of a 2 - Partition SystemA two partition system must have a minimum of two drives, but may have threeor four drives. Partition 1 will contain any drives in drive position 1 and driveposition 2. Partition 1 will also contain magazine 1 and magazine 2. Partition 2 willcontain any drives in drive position 3 and drive position 4. Partition 2 will alsocontain magazine 3 and magazine 4.When configured with two logical partitions, the Element Address assignmentswill be as follows: DTE assignments will be as shown in Figure A-2 on page A-5.STE assignmentsv Logical Library 1: Slot 1 through slot 21 4096 (x1000) through 4116 (0x1014)a77ug161Drive 3258Element AddressDrive 2257Element AddressDrive 1256Element AddressDrive 2257Element AddressDrive 1256Element AddressDrive 3258Element AddressDrive 4259Element AddressDrive 3258Element AddressDrive 1256Element AddressDrive 1256Element AddressDrive 2257Element AddressMagazine1Magazine2Magazine3Magazine4Front sideDrive 4259Element AddressFigure A-1.
