#5709 RAID Enabler Card
The #5709 RAID Enabler Card has 16 MB write cache. It supports up to eight
disk unit positions in the Model 520 and 550 system unit and up to six disk unit
positions in the Model 570 system unit. The #5709 is not supported on the Model
595. The #5709 provides RAID capability to the embedded SCSI controller. It
plugs into its own specific internal slot and does not require or use a PCI card
slot. Hardware disk compression is not supported.
In the Model 520 you can use the #5709 with or without a #6574 4-Disk Slot
Expansion. When installed without a #6574, the #5709 supports four disk units.
When installed with a #6574, the #5709 supports a maximum of eight disk units.
In the Model 550 you can use the #5709 with a #6592 4-Disk Slot Expansion.
When installed without a #6592 the #5709 supports four disk units. When
installed with a #6592, the #5709 supports a maximum of eight disk units.
The #5709 is an optional feature for the Model 520 and 550. It is required for the
Model 570.
It is supported in Models 520, 550, and 570 with i5/OS V5R3.
It is not supported on the Model 595
The #5709 is a Customer Install Feature.
#5712 PCI-X Tape Controller
The #5712 is an Ultra SCSI controller for attachment of two external tape devices
or an external CD-ROM device that has a single-ended SCSI interface.
Each port of the #5712 PCI-X Tape/DASD Controller
supports one, or a
combination, of these devices:
Note: The i5/OS operating system does not have the capability to interface
directly to the embedded SCSI controller. The #5709 communicates solely
with the embedded controller. An IOP must be present for the #5709 to
communicate with the i5/OS operating system.
Note: The #5712/5702 is the best choice when the customer is using i5/OS
V5R3 or OS/400 V5R2 and the tape drive being attached uses an Low Voltage
Differential (LVD) SCSI interface such as the 358x LTO-2, 7207-330 (30GB
QIC) and 7206-VX2 (80GB VXA-2).Note the #5712/5702 is rated at up to 160
MBps. This is a good match for 358x LTO-2 tape drives.
