HPE ProLiant BL685c G7 Parts

The HPE ProLiant BL685c G7 is the four-socket AMD Opteron member of the c-Class blade family: a single-wide, full-height server blade carrying 32 DDR3 DIMM slots, two hot-plug drive bays and three mezzanine slots, and drawing its power and cooling from the enclosure around it. Every part below is genuine HPE, available new and refurbished, and tested for compatibility before it ships. Live pricing for each part number appears in the tables further down this page.

BL685c G7 Platform at a Glance

• Processors: up to four AMD Opteron processors on the AMD SR5690 and SP5100 chipset, in two-processor and four-processor configurations only — never one, never three
• Memory: 32 DDR3 Registered DIMM slots, eight behind each processor across four channels of two slots, documented to 1TB
• Drive bays: two hot-plug small form factor SAS, SATA or solid state bays, with SAS, SATA and SSD drives unable to be mixed in one blade
• Maximum internal storage: 2.4TB on two 1.2TB SAS drives, 2.0TB on two 1TB SATA drives, or 3.2TB on two 1.6TB solid state drives
• Storage controller: HPE Smart Array P410i with a 1GB flash backed write cache, supporting RAID 0 and RAID 1
• Networking: two embedded HPE NC551i dual-port FlexFabric 10Gb Converged Network Adapters carrying TCP Offload Engine, FCoE and iSCSI, plus a separate 10/100 adapter dedicated to iLO 3
• Expansion: three I/O mezzanine slots, all x8 PCIe 2.0, routing to the enclosure interconnect bays rather than to brackets on the blade
• Power and cooling: supplied entirely by the enclosure — the blade has no power supplies, fans or rails of its own, and HPE specifies ten fans in a c7000 and six in a c3000 for this model
• Enclosure footprint: up to eight blades in a 10U BladeSystem c7000, or up to four in a 6U c3000, each taking a full-height bay
• Management: embedded HPE iLO 3, an internal USB connector, an internal MicroSD card slot and a TPM 1.2 option

A BL685c G7 brings nothing to the rack but itself. There are no power supplies, no fans and no rails in this blade — the c3000 or c7000 enclosure supplies all of it, and HPE specifies ten fans in a c7000 and six in a c3000 for this model. Expansion works the same way: the three mezzanine slots route into the enclosure's interconnect bays, not into brackets on the blade.

BL685c G7 Parts FAQ

How many processors does a BL685c G7 take?
Four AMD Opteron processors at most, and HPE supports two-processor and four-processor configurations only. That is why every processor option kit for this blade contains two processors rather than one.

Does the BL685c G7 have its own power supplies and fans?
No. It is a c-Class server blade, so power and cooling come from the enclosure it plugs into. HPE specifies ten fans in a c7000 enclosure and six in a c3000 for this model.

How many BL685c G7 blades fit in an enclosure?
Up to eight in a 10U BladeSystem c7000, or up to four in a 6U c3000. It is a single-wide, full-height blade, so each one consumes a full-height bay.

How many drives does a BL685c G7 hold?
Two, in hot-plug 2.5-inch bays that take SAS, SATA or solid state drives. The three types cannot be mixed in one blade, so both bays carry the same kind of drive.

What networking is built into the BL685c G7?
Two embedded NC551i dual-port FlexFabric 10Gb Converged Network Adapters, supporting TCP offload, FCoE and iSCSI, plus a separate 10/100 adapter dedicated to iLO 3 management. Each 10Gb port autosenses between 1Gb and 10Gb.

Do add-in cards for this blade fit a standard PCIe slot?
No. The three expansion slots take c-Class mezzanine cards. Each is an x8 PCIe 2.0 connection that routes into the enclosure interconnect bays instead of terminating in a bracket on the blade.
