can be spread across four or eight disk units. A maximum of three RAID-5 arrays are

supported on one #2726. Disk units not supported in a RAID-5 array can be attached to the

#2726 in either unprotected or a mirrored environment.

Concurrent maintenance of disks attached to the #2726 is only supported if the disks are part

of a RAID array or are mirrored.

The supported internal tape drives include:

• 1.2G ¼-inch Cartridge Tape Unit Kit, #1349

• 2.5G ¼-inch Cartridge Tape Unit Kit, #1350

• 13G ¼-inch Cartridge Tape Unit Kit, #1355

• 7G 8mm Cartridge Tape Unit Kit, #1360

• 2.5G ¼-inch Cartridge Tape Unit, #6481

• 4G ¼-inch Cartridge Tape Unit, #6482

• 13G ¼-inch Cartridge Tape Unit, #6485

• 16 G ¼-inch Cartridge Tape Unit

• 25G ¼-inch Cartridge Tape Unit, #6486

• 7G 8mm Cartridge Tape Unit, #6490

The #2726 occupies one High Speed PCI card slot. It is supported on the 9406 Model 720

only. A maximum of one #2726, #2740, #2741, or #9728 can be installed in the system unit

and one #2726 or #2741 in the #5064/#9364 System Unit Expansion with the #9329

Expansion Unit for PCI cards. If RAID is to be implemented or more than five disk units are

required in the system unit, the #2726 should be ordered in place of a #9728 Base PCI Disk

Unit Controller.

The #2726 does not offer support for compression. The #2741 PCI Raid Disk Unit Controller

supports compression when used with V4R3, and it effectively supersedes the #2726. If a

maximum of only ten disks is required and there is no requirement for compression, the

#2740 can be ordered as an alternative to the #2741.

#2729 PCI Magnetic Media Controller SCSI PCI

The #2729 PCI Magnetic Media Controller SCSI provides for attachment of one of these

devices:

• 3490E-C11/C22/C1A/C2A ½-inch Cartridge Tape Subsystem with #5040

• 3490E-E01/E11 ½-inch Cartridge Tape Subsystem

• 3490E-F00/F01/F11/F1A ½-inch Cartridge Tape Subsystem

• 3494-L10 ½-inch Cartridge Tape Library Control Unit Frame (one 3490E-C1A/C2A with

#5040 or one or two 3490E-F1A)

• 3494-L12 ½-inch Cartridge Tape Library Control Unit Frame (one or two 3590-B1A)

• 3494-D10 ½-inch Cartridge Tape Library Device Frame (one 3490E-C1A/C2A with #5040

or one or two 3490E-F1A)
