HPE Smart Array P408e-p SR Gen10 Controller

The HPE Smart Array P408e-p SR Gen10 Controller is a 12Gb/s SAS RAID card that connects to externally attached drives through a PCI Express 3.0 x8 host interface. It provides eight external SAS lanes for SAS or SATA 600 devices and includes 4 GB flash-backed write cache. The controller supports advanced RAID levels and operates in Mixed Mode for simultaneous RAID and HBA operations.

Suited for external storage arrays.

This controller targets administrators who need to attach external SAS or SATA storage enclosures to a Gen10 server while using hardware RAID with flash-backed write cache. It also fits environments that require simultaneous RAID and HBA functionality through Mixed Mode operation. Buyers who need internal drive connectors or internal cabling should consider a different adapter.

Eight external SAS lanes define connectivity

The single specification that decides fitment is the eight external SAS lanes provided by the controller. These lanes determine how many externally attached SAS or SATA drives can be connected and whether the card matches the external enclosure cabling plan. Verify the lane count against your enclosure requirements before purchase.
