Dell DD and PowerProtect Hardware 8.0 Features and Specifications
DD6400 cabling
Management cabling
The DD6400 provides two methods to access the system console: a dedicated iDRAC management 10/100/1000Base-T port and an RS-232 serial RJ-45 port. Both are at the rear of the enclosure.
A minimum of TIA or EIA 568-B Cat5 twisted-pair copper cables with RJ-45 jacks up to 100 m in length can be plugged into the management 10/100/1000GbE port. Cat 5E, Cat 6, and Cat6A cables, up to 100 m in length may also be used.
Serial over LAN or RJ-45 connector provides the serial console for the system. A null modem adapter is used. The system serial console is configured for a terminal type of VT100+, 115200 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
Host interface cabling
The DD6400 LOM card (DPN) provides two 10GBase-T Host Interface ports. RJ-45 connectors provide the interface to the 10GBase-T copper cables. The 10GBase-T ports support 100 m cable length with category 6 cable or 55 m with category 6 cable.
The alternate LOM (DPN) provides 1 20G SFP+ ports. The SFP+ connectors should be populated with 850 nm 10 GbE Optical Transceivers supporting the 10GBASE-SR standard (DPN or equivalent).
This set of 4-port HBAs (DPNs) supports the same cable as 10GBase-T LOM.
The SFP28 connectors on the (DPNs) 25 GbE dual port cards are populated with 850 nm 10GbE/25GbE Optical Transceivers supporting both the 10GBASE-SR and the 25GBASE-SR standard (DPN M14MK).
The SFP+ connectors on the (DPNs) 10 GbE dual port are populated with 850 nm 10 GbE Optical Transceivers supporting the 10GBASE-SR standard (DPN C5RNH).
Supported optical fiber cable lengths depend on the type of optical fiber that is connected to the SFP+ Optical Transceivers. The following table summarizes the supported 10GBASE-SR lengths that are provided by the SFP+ transceiver:
| Fiber Type | Minimum modal bandwidth @ 850 nm (MHz*km) | Operating range (meters) |
|---|---|---|
| 62.5 µm MMF (OM1) | 160 | 2–26 |
| 62.5 µm MMF (OM1) | 200 | 2–33 |
| 50 µm MMF (OM2) | 400 | 2–66 |
| 50 µm MMF (OM2) | 500 | 2–82 |
| 50 µm MMF (OM3) | 1500 | 2–300 |
| 50 µm MMF (OM4) | 3500 | 2–400 |
The FibreChannel HBA provides two 16Gbps Fibre Channel ports. The card contains two SFP+ ports that accommodate 16 Gb SFP+ Optical Transceivers.
The SFP+ connectors on the HBA are pre-populated with QLogic certified 850 nm 16 Gb Fibre Channel Optical SFPs.
The maximum supported cable distance depends on both the data rate and optical cable type (OM1, OM2 or OM3). The following table summarizes the maximum supported cable lengths:
| Data Rate | Multi-Mode Optical Cable Type | ||
|---|---|---|---|
| OM1 | OM2 | OM3 | |
| 4 Gb FC | 70 m | 150 m | 380 m |
| 8 Gb FC | 21 m | 50 m | 150 m |
| 16 Gb FC | 15 m | 35 m | 100 m |
SAS cabling
The 15-disk drive array enclosure ES40 is supported with DD6400 systems. The mini-SAS-HD cable is used to connect a DD6400 system with ES40 enclosure. There is no special keying feature to differentiate connections between the first node or the second node in an A-P HA configuration. Typical cable length and their part numbers are listed below.
ES40 shelves come with a 1M Mini-SAS-HD to Mini-SAS-HD cable. That length is enough for most installations. The cables that are listed in the table can be used but must be ordered.
| Description | Part number |
|---|---|
| 1M 12G MINI-HDX4 TO MINI-HDX4 HAL-FREE | 038-004-448-00 |
| 2M 12G MINI-HDX4 TO MINI-HDX4 HAL-FREE | 038-004-449-00 |
| 3M 12G MINI-HDX4 TO MINI-HDX4 HAL_FREE | 038-004-450-00 |
| 5M 12G MINI-HDX4 TO MINI-HDX4 CABLE | 038-004-382-01 |
