749680-B21 is the HPE Smart Array P244br/1GB FBWC 12Gb 2-ports Int SAS Controller. It connects to the server through x8 PCIe 3.0, for 8GB/s of maximum bandwidth, and its drive interfaces are 12Gb/s SAS and 6Gb/s SATA. The 1GB flash-backed write cache is standard, and the controller supports 64 logical drives with RAID 0 and RAID 1.
It fits the ProLiant BL460c Gen9 server blade, where it is one of three storage choices with the Smart HBA H244br and the chipset B140i. The blade has two small form factor hot-plug drive bays. HPE Secure Encryption is supported on the P244br, and its firmware is upgradeable with a recovery ROM and online drive flash with SAS drives.
The HPE Gen9 Broadwell NVMe FIO setting 825555-B21 is not compatible with the P244br. The four-port P246br, 726793-B21, is only required with a PCI expansion blade or a D2220sb storage blade, and the 2-port H244br host bus adapter is 726809-B21.
The spare number is 749800-001, a Smart Array PCIe P244br 2-port 12Gb SAS RAID controller that includes the 1GB flash-based write cache. The cache is not a separate part. Battery spares are 750452-001, a 12W 7.2V MegaCell capacitor pack, and 815984-001, an Enhanced Megacell 12W module.
