Installing the enclosures

Figure 10

Cabling connections between dual controllers and drive enclosures of mixed type

The figure above shows a sample fault-tolerant cabling scenario on left, and a straight-through cabling

scenario on right. Both diagrams show drive enclosures of mixed type. Do not mix SAS1.1 and SAS2.0

expanders, except as described in

Additional cabling considerations

on page 26. Avoid mixing them

except when upgrading legacy systems.
In the illustration on the left, note that the D2700 6Gb drive enclosures could alternatively be cabled before

the P2000 6Gb drive enclosures. The illustration at the right shows a D2700 6Gb drive enclosure before a

P2000 6Gb drive enclosure, MSA70 3Gb drive enclosure, and MSA2000 3Gb drive enclosure. Note that

the MSA2000 3Gb drive enclosure is cabled after the other drive enclosures, using straight-through

cabling.
Although 6Gb drive enclosures can be cabled after an MSA70 3Gb drive enclosure, performance of the

6Gb devices will be limited to 3Gb.

IMPORTANT:

For comprehensive configuration options and associated illustrations, refer to the HP

P2000 G3 MSA System Cable Configuration Guide.
