5486IOA.fm Draft Document for Review October 18, 2004364 IBM Eserver i5 and iSeries System HandbookThe #0120 7210-020 Attachment Specify is required for each 7210-020 ExternalCD-ROM Drive to be connected directly (not daisy chained) to the systemthrough a #5702.The #0162 Extended Single Ended Attach Specify is required when thesedevices are directly attached (not second on a daisy chained string) to an iSeriesserver, via a #5702 PCI-X Ultra Tape Controller: 7329-308 SLR100 ¼-inch Tape Autoloader 7210-025 External DVD-RAMThe #5702 PCI-X Ultra Tape Controller is hot pluggable.When used as a Direct Attached Adapter, order the #0624 in place of the #5702.#5703 PCI-X RAID Disk Unit ControllerThe #5703 PCI-X RAID Disk Unit Controller is an Ultra3 SCSI controller with acache size of 40 MB that provides RAID-5 protection for internal disks andinternal tape units, CD-ROM, DVD-RAM, and DVD-ROM units. The #5703 hastwo Ultra3 SCSI buses and runs on a U320 (320 MB/s) data rate.In addition to providing RAID-5 protection for disks, the #5703 is designed towork as a high performance controller for disks protected by system mirroring ordisks with no protection. In the RAID-5 configuration, disk unit protection isprovided at less cost than mirroring, and with greater performance than systemchecksums.The #5703 controller supports a maximum of 12 disk units. DASD compressionis not supported.Note: If the 7210-020 is daisy chained with another external device, the #0120specify code must not be present.Note: If either of these devices is daisy chained with another device, the#0162 specify code must not be present.Note: The #5702 has both internal and external SCSI ports. Devices cannotbe attached both internally and externally on the same bus.
