698532-B21 HPE Smart Array P431 4GB FBWC Controller
HP
HPE internal replacement Smart Array P431 12Gb/s 2-port external SAS PCIe 3.0 x8 RAID controller kit with 4GB Flash-Backed Write Cache (FBWC) and capacitor battery.
The 698532-B21 is an internal data connectivity interface module engineered to deliver cost-effective network transformation and enhanced system stability within multi-node server frameworks. Functioning as a high-reliability RAID controller unit and high-bandwidth external SAS storage interface layer, this 12Gb/s 2-port external SAS PCIe expansion controller module slides directly into enterprise chassis backplane bays using localized connection lines. Operating under 12Gb/s SAS transfer rate parameters across Serial Attached SCSI and PCI-Express 3.0 bus architectures, it establishes high-efficiency routing pathways to manage internal data processing pipelines across high-density databases, continuous multi-threaded enterprise workloads, and legacy hardware consolidations. Its low-profile PCIe plug-in card form factor and fault-isolated controller architecture manage internal bus communication cleanly, shielding core operational paths from signaling latency, packet drops, or single-point-of-failure throughput disruptions during continuous high-availability enterprise runtime operations.
