1. Maximum supported speeds may be limited by installation of lower speed devices, controllers or cable lengths greater than 2 meters.
2. Rack installation cable management requires devices to have a minimum cable length of 2 meters. Cable length requirements will vary based on placement within a single or multiple rack suite.
3. Attachment to wide ultra SCSI controllers limits operational speeds to Ultra SCSI (40 MB/s) for cables up to 2 meters in length and Fast/Wide SCSI (20 MB/s) for cable lengths between 2 meters and 4.3 meters. Ultra2 SCSI controllers and cables allow cable
lengths of up to twenty meters at up to 40 MB/s.
4. Attachment to wide ultra SCSI controllers limits operational speeds to Ultra SCSI (40 MBps) for cables up to two meters in length and Fast Wide (20 MBps) for cable lengths between 2 meters and 4.3 meters. Ultra2 SCSI controllers and cables allow
cable lengths up to 20 meters at up to 80 MBps.
5. Maximum speeds may be limited by the installed devices or SCSI controller.
6. Daisy chaining tape enclosures is not supported at this time.
7. Requires 68-pin External Multimode LVD/SE SCSI Terminator (P/N 00N7956).
8. NetMEDIA Systems Management Adapter (P/N 10L7113) may be installed in a
Expansion Unit
termination when the is powered off. External connector is 0.8-mm VHDCI.
9. Connection to either IBM SAN Fibre Channel Managed Hub (P/N 35L1647) or Netfinity Fibre Channel PCI Adapter (P/N 01K7297) requires short wave fibre cables from Cable Group D.
10. Cable lengths exceeding 4.3 meters are NOT supported for attachment to non-Ultra-2 controllers.
11. Installations with cable lengths greater than 2 meters are limited to SCSI Fast/Wide speeds of 20MB/S .
12. RAID support for tape drives is limited to Non-RAID functions and utilisation of a dedicated channel.
13. Maximum speeds may be limited by the enclosure or installed devices.
14. Netfinity 7600 also includes a Netfinity ServeRAID-3HB Ultra2 SCSI Adapter (P/N 37L6086). See ServeRAID-3HB for connectivity requirements.
15. Does not support external attachment of SCSI devices attached to optional controllers.
16. Converts a F0.8mm into a F68-pin connector for attachment of an external M68 cable .
17. Supports attachment to Ultra-2 or single-ended SCSI controllers with operational speeds of up to Ultra-2. Controller, storage unit, cable length or storage device limitations may apply (see Max. MB/sec row and column above).
18. Netfinity EXP200 (P/N 00N6xxx) and EXP300 (P/N 19K11xx) include a single 2 metre Ultra2 SCSI cable similar to Netfinity 2 M Ultra2 SCSI Cable (P/N 03K9310).
19. See Fibre Array Solutions section for device attachment.
20. Short wave GBICs are included with various devices. See Fibre Array Solutions section for specific details.
21. The RAID adapter has both an internal and external port. Only one of the two ports may be used. The internal HDDs are attached to the RAID adapter therefore the external port must not be used.
22. No external SCSI port is available on these systems. A supported optional controller must be installed. See the systems section to determine which controllers and external storage units are supported then refer back to this table for cable requirements using the
controller row. The Netfinity 4000R does not support customer installation of adapters that must be installed inside the server. Non-standard features must be installed at the factory. Contact your IBM Marketing Representative for more information.
23. Not supported for use in a rack. Rack installations require a minimum cable length of two meters.
Instructions:
Identify Desired Controller Row and Storage Unit Column. The intersection of row and column contains the cable group letter which supports the
connection. Go to the cable group under the corresponding storage unit for specific support. Read all Notes for row, column, and any cable group footnotes.
