HPE sells the P204i-b as option 804367-B21: the HPE Smart Array P204i-b SR Gen10 (4 Internal Lanes/1GB Cache) 12G SAS Modular Controller. It is a type-b modular controller with 4 SAS lanes across an internal SAS port and a 1GB flash-backed write cache (FBWC) with read ahead and write-back caching.
Drives can be 12Gb/s SAS or 6Gb/s SATA on the same controller, over a PCI Express 3.0 x8 link, with up to 238 physical drives and up to 64 logical drives. RAID levels are 0, 1, 5, 6, 10 and 1 ADM, and Mixed Mode runs RAID logical drives and HBA physical drives together. HPE Smart Array SR Secure Encryption is an optional license.
The ProLiant BL460c Gen10 server blade takes either this controller or the S100i SR Gen10 SW RAID, and both support up to two SFF or four uFF hot plug drive bays. The P204i-b needs the HPE 12W Smart Storage Battery, P01363-B21, ordered separately, and the HPE Gen10 NVMe FIO Setting, 873373-B21, is not compatible with it. Further modular and mezzanine controllers are in HPE server interface cards.
