The #2729 does not provide Hardware Data Compression (HDC).
When attaching Ultra SCSI to a #2729, the instantaneous data transfer rate is 20 MB/sec,
and sustained 13 MB/sec.
The #2729 occupies one High-Speed PCI card slot. It requires OS/400 V4R1 or later. It is
supported on the 9406 Models 170 and 720, and the #5065 Storage/PCI Expansion
Tower/#5066 1.8 I/O Tower. A maximum of one #2729 can be installed in the system unit and
two #2729s in the #5064/#9364 System Unit Expansion with #9329/#9330 Expansion Unit for
PCI cards. Up to three #2729s can be installed in #5065 Storage/PCI Expansion Tower.
The #2809/#2824 PCI Feature Controller or the base PCI LAN/WAN Workstation IOP in the
#5065 Storage/PCI Expansion Tower/#5066 1.8 I/O Tower is a prerequisite for the #2729.
OS/400 V4R2 or later is required for the #2729 to support the 3995 Optical Library
Dataserver.
#2740 PCI RAID Disk Unit Controller
The #2740 is functionally equivalent to the #2726 PCI RAID Disk Unit Controller. However,
the #2740 can only be located in the System Unit. It cannot be located in the System Unit
Expansion #5064/#9364. The #2740 is supported on the 9406 Models 170 and 720 only. The
#2740 supports a maximum of 10 one- or two-byte disk units. A maximum of two RAID-5
arrays are supported on one #2740. A maximum of one #2740, #2726, #2741, #2748, or
#9728 can be installed in the system unit. The #2740 does not offer support for compression.
However, if only a maximum of 10 disks are required and there is no requirement for
compression, the #2740 should be ordered.
Concurrent maintenance of disks attached to the #2740 is only supported if the disks are
mirrored or part of a RAID array. Otherwise, the #2740 offers the same support as the #2726.
