  • Mixed Mode runs RAID and HBA functions simultaneously

HPE Smart Array P408i-a SR Gen10 Controller

The HPE Smart Array P408i-a SR Gen10 Controller is a 12Gb/s SAS RAID card with eight internal lanes for SATA and SAS drives. It connects through a PCI Express 3.0 x8 host interface and includes 2 GB flash-backed write cache. The type-a modular design fits a dedicated storage slot without using a standard PCIe expansion slot.

Suited for internal SATA and SAS arrays.

This controller suits servers that need mixed RAID and HBA operation on internal drives with encryption for data-at-rest. It supports RAID 0, 1, 5, 6, 10, 50, 60, 1 ADM and 10 ADM. Builders who require external drive connections or a different slot form factor should look at another part.

PCI Express 3.0 x8 host interface

The card installs in a dedicated storage slot using a PCI Express 3.0 x8 link, leaving standard expansion slots free. Confirm the server has this specific slot type before ordering. The HPE Smart Storage Battery for cache backup is sold separately.

Questions about this item

What RAID levels does the 869081-B21 controller support in a live server?

The card supports RAID 0, 1, 5, 6, 10, 50 and 60, plus Advanced Data Mirroring levels 1 ADM and 10 ADM for extra redundancy.

How does the PCIe 3.0 x8 host link limit throughput on this 12 Gbit/s SAS controller?

The x8 lane at PCIe 3.0 provides roughly 8 GB/s of bus bandwidth, which is the practical ceiling even though each SAS lane can run at 12 Gbit/s.

What slot type does the P408i-a SR Gen10 need for installation?

It uses a dedicated type-a modular storage slot inside the server, so it does not consume a standard PCIe expansion slot.
