Figure B-5. The c3000 Enclosure is divided by sheet metal panels into 2 full-height zones. Each horizontal zone is divided vertically by a removable shelf to make a maximum of 8 half-height device bays. These zones reflect the PCIe bus mapping in the signal midplane and limit placement of the server blade/storage blade combination. The signal midplane has a direct PCIe link connecting adjacent paired device bays. Important: The server blade/storage blade relationship cannot extend horizontally beyond the vertical dividers between full height device bays, nor can it span the removable bay shelf dividing the zone into half-height device bays
.
The enclosure comes preinstalled with removable full-height dividers between the top four device bays and the bottom four device bays. In addition, there is a half-height divider available for use between device bays 4 and 8 if the full-height divider is removed. Using these combinations of dividers, the following combinations of server blades can be installed:
•8 half-height server blades with both full-height dividers installed
•4 full-height server blades with both full-height dividers removed
•4 half-height server blades in the bottom half of the enclosure with 1 full-height divider installed
•2 full-height server blades in the bottom half of the enclosure with 1 full-height divider removed
•4 half-height server blades in the top half with 1 full-height divider installed
•2 full-height server blades in the top half with 1 full-height divider removed
•1 full-height server blade and 2 half-height server blades in the top half with 1 full-height divider removed and the half-height divider installed
CAUTION
If a full-height server blade is installed in device bay 1/5 and half-height server blades are installed in device bays 2 or 6, removing the full-height server blade leaves server blades installed in device bays 2 and 6 unsupported. This might cause damage to the server blades and the enclosure connectors.
Removing the full-height divider in the bottom half of the enclosure allows only full-height server blades to be installed in the bottom half of the enclosure.
Removing the full-height divider in the top half of the enclosure requires either installing only full-height server blades in the top half of the enclosure or installing the half-height divider between device bays 4 and 8. Installing the half-height divider enables installation of two half-height devices (two server blades, one companion blade and one server blade, or one blade blank and one companion blade or server blade) in device bays 4 and 8 and 1 full-height server blade in device bay 3/7.
