830824-B21 is the HPE option part number for Smart Array P408i-p SR Gen10 (8 Internal Lanes/2GB Cache) 12G SAS PCIe Plug-in Controller. It is a plug-in RAID storage controller on a PCIe 3.0 x8 host bus, with eight channels supporting 12Gb/s SAS and 6Gb/s SATA devices. A 2GB cache buffer backs write operations, and the controller supports RAID 0, 1, 1 ADM, 10, 10 ADM, 5, 50, 6 and 60 across up to 64 LUNs. Use it when a configuration calls for hardware RAID across hard drives and disk arrays in a supported Gen9 v4 CPU server platform.

FREQUENTLY ASKED QUESTIONS ABOUT 830824-B21
What is the difference between 830824-B21 and 836269-001?
They are the same physical controller under two HPE part-numbering schemes. 830824-B21, the subject of this page, is the option part number, the number used when ordering the controller as a configurable or aftermarket option. 836269-001 is the spare part number, which is how the same board is identified for service replacement. The hardware, specifications and RAID capabilities are identical; only the ordering context differs.
What RAID levels does 830824-B21 support?
The P408i-p SR Gen10 supports RAID 0, RAID 1, RAID 1 ADM, RAID 10, RAID 10 ADM, RAID 5, RAID 50, RAID 6 and RAID 60. That covers striping, mirroring, advanced data mirroring, single- and dual-parity sets and their nested variants. The controller supports a maximum of 64 LUNs, so plan array and logical drive counts within that limit for the configuration you are building.
What is the host interface and drive interface?
The card installs in a PCIe 3.0 x8 slot as a plug-in form factor controller. On the storage side it provides eight channels supporting 12Gb/s SAS and 6Gb/s SATA, with two SATA 6Gb/s / SAS 12Gb/s connectors. Supported devices are hard drives and disk arrays. Confirm the target server has an available PCIe 3.0 x8 electrical slot before ordering.
How much cache does the controller have?
830824-B21 carries a 2GB buffer. This cache is used to accelerate read and write operations against attached SAS and SATA drives and is part of the base card rather than a separate module. If your configuration is being sized against a cache requirement, 2GB is the figure to record for this part number.
Which servers is 830824-B21 listed as compatible with?
Listed compatibility covers HPE Gen9 platforms with v4 CPUs: BL460c, DL60, DL80, DL120, DL160, DL180, DL360, DL380, ML110, ML150, ML350, XL170r, XL190r and WS460c. Verify the receiving server has an appropriate PCIe 3.0 x8 slot and internal drive cabling for the eight-lane configuration before finalizing the build.
