Server Blade, Expansion Blade, and Fan Population Guidelines
Expansion blades
Expansion blades consist of storage blades, tape blades, and the PCI Expansion Blade. Up to 4 expansion blades are supported per HP
BladeSystem c-Class c7000 Enclosure. Expansion blades may be installed in the same zone as half-height and full-height server
blades. An expansion blade is installed directly above a server blade, also known as a partner server blade. An overview of the
expansion blade population rule best practices are summarized below. For detailed expansion blade rules and guidelines, please see
the documentation that ships with the enclosure and expansion blade.
Expansion blade population best practices for half-height server blades:
1.
One half-height partner server blade supports one expansion blade.
2. Identify the partner server blade to be installed with the expansion blade. The two blades always occupy a pair of slots as
follows: 1 & 2, 3 & 4, 5 & 6, and 7 & 8.
3. Each c3000 zone contains a removable divider (also known as a device bay shelf) that is used to support half-height devices.
This divider is remains installed whether the half-height devices are server or expansion blades.
Expansion blade population best practices for full-height server blades:
1. A full-height server blade may be mixed with half-height expansion blades in zone 2 (the upper zone) of the c3000 enclosure;
mixing is not allowed in zone 1 (the lower zone).
2. The full-height partner server blade must be installed in the lower bays 3 and 7 and half-height devices directly above in bays 4
and 8.
3.
The full-height server partner blade supports one or two expansion blades in bays 4 and 8.
4.
Before installing any full-height server blades, remove the bay divider that is used to support half-height devices.
5.
A mini-divider is installed between bays 4 and 8. A mini-divider is shipped with each c3000 enclosure.
6.
If installing only one expansion blade, install the expansion blade in bay 8. The remaining half-height bay (bay 4) may be
populated with either a half-height device bay blank of a half-height server blade; the half-height server blade may not be
partnered with the expansion blade.
7. If installing two expansion blades, the expansion blades may be two storage blades, two tape blades, two PCI Expansion Blades,
or a mixture of any two.
NOTE: Please read the RTF card (included with each c3000 enclosure) and the "HP BladeSystem c3000 Setup and Installation Guide" for
more information on using bay dividers and the mini-divider for mixed configurations.
NOTE: For detailed expansion blade rules and guidelines, please see the documentation that ships with the enclosure and expansion
blade.
