HPE ProLiant BL490c G7 Parts

The HPE ProLiant BL490c G7 is the memory-dense half-height blade of the c-Class G7 line, sold as a virtualisation host: HPE gave it eighteen DDR3 DIMM slots and paid for them with drive bays, so internal storage is two non-hot-plug solid state drives and nothing else. 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.

BL490c G7 Platform at a Glance

• Form factor: a half-height c-Class server blade — up to sixteen fit an HPE BladeSystem c7000 enclosure at 10U, plugged vertically, and up to eight fit a 6U c3000 enclosure, plugged horizontally
• Power and cooling: supplied entirely by the enclosure; the blade carries no power supplies, fans or rails of its own, and HPE calls for ten fans in a c7000 or six in a c3000 for optimal cooling of this model
• Processors: up to two Intel Xeon 5600 series on the Intel 5520 chipset, each carrying 12MB of shared L3 cache
• Memory: eighteen DDR3 slots — nine per processor, three channels each with three slots — documented to 384GB Registered or 48GB Unbuffered
• Internal storage: two non-hot-plug 2.5-inch SATA solid state bays on a baffle above the processors, 800GB maximum on a pair of 400GB drives
• Storage controller: an embedded chipset SATA RAID controller limited to RAID 0 and 1, with hardware RAID available through a Smart Array mezzanine card
• Networking: an embedded NC553i dual-port FlexFabric 10GbE adapter carrying TCP Offload Engine, FCoE and iSCSI, plus a separate 10/100 NIC for iLO 3 — HPE rates the blade for up to 24 NICs in total
• Expansion: two x8 PCI Express mezzanine slots, feeding the enclosure's interconnect bays
• Also listed on this page: Gigabit and 10GbE mezzanine adapters, Fibre Channel and InfiniBand mezzanine HCAs, I/O Accelerator cards, the BLc PCI Expansion Blade, a StorageWorks storage blade and Ultrium tape blades — these have no category page of their own and appear in the tables below

This is the blade that traded drive bays for DIMM slots. Eighteen DDR3 slots in a half-height bay, and internal storage of exactly two non-hot-plug SATA solid state drives — 800GB at most. Power, cooling and networking all come from the enclosure, so there are no power supplies, fans or rails to buy for it.

Specifications on this page are taken from the HPE QuickSpecs for this server blade, HPE ProLiant BL490c Generation 7 (G7) Server Blade QuickSpecs, Version 16.

BL490c G7 Parts FAQ

Which enclosures take a BL490c G7?
Both c-Class enclosures. An HPE BladeSystem c7000 is 10U and holds up to sixteen of these half-height blades plugged vertically; a c3000 is 6U and holds up to eight plugged horizontally.

Does the BL490c G7 have its own power supplies and fans?
No. Power and cooling come from the enclosure. HPE does note that for optimal cooling this blade wants a c7000 configured with ten fans, or a c3000 configured with six.

What makes the BL490c G7 different from the other G7 blades?
Memory. It carries eighteen DDR3 DIMM slots in a half-height bay, which is where its drive bays went - internal storage is two non-hot-plug SATA solid state drives, 800GB at most.

How many drives does a BL490c G7 hold?
Two. Both are non-hot-plug 2.5-inch SATA bays mounted on a baffle above the processors, and no cage or backplane option adds a third inside the blade.

How does a BL490c G7 connect to the network?
Through an embedded NC553i dual-port FlexFabric 10GbE adapter, which supports FCoE and iSCSI, plus up to two mezzanine cards in the blade's x8 PCI Express slots. All of it lands in the enclosure's interconnect bays.

Is the BL490c G7 still worth buying parts for?
It remains a practical virtualisation host wherever a c3000 or c7000 enclosure is already in service, and memory and processor kits for it are plentiful. Because HPE has retired the documentation for this generation, matching part numbers to the blade you actually own carries more weight here than on a server still in production.
