The HPE BladeSystem PCI Expansion Blade provides PCI card expansion slots to an adjacent c-Class blade server. This blade expansion unit uses the c-Class midplane to pass standard PCI signals between adjacent enclosure bays, to allow a c-Class blade server to add off-the-shelf PCI-X or PCI-e cards. Customers would need one PCI Expansion Blade for each c-Class server blade needing PCI card expansion. Any PCI card from third-party manufacturers that works in HPE ProLiant ML and HPE ProLiant DL servers should work in this PCI Expansion Blade. HPE does not offer any warranty or support for third-party PCI manufactured products. HPE does joint market with selected PCI manufactures via the HPE BladeSystem Solutions Builder Program.
