Redundant And Scalable - HP BladeSystem c3000 Manual

Figure 16. HP BladeSystem c3000 self-sealing enclosure

Redundant and scalable

BladeSystem c3000 enclosures ship with four installed fans that provide redundancy and support up
to four half-height devices in device bays 1, 2, 5, and 6, or two full-height server blades in device
bays 1 and 2. Adding two additional fans to the enclosure allows population of eight half-height
devices or four full-height server blades.
In a four-fan configuration, the Onboard Administrator prevents server and storage blades installed in
device bays 3, 4, 7, and 8 from powering on until two additional fans are added into fan bays 1
and 3. To populate blade devices in all eight device bays, it is necessary to populate c3000
enclosures with six Active Cool fans. Figure 17 shows enclosure fan bay and device bay population
guidelines. See the Appendix for more detailed fan and device bay population guidelines.
