HP 656596-B21 530T 10Gb Ethernet Network Adapter

The HP 656596-B21 530T is a dual-port 10Gb Ethernet network adapter engineered for HP ProLiant Gen8 servers that require high-speed, low-latency network connectivity. Built around a PCI Express 2.0 x8 interface, the adapter delivers two independent 10GBase-T ports using standard RJ-45 connectors, allowing organizations to leverage existing copper cabling infrastructure for 10Gb networking without the additional expense of fiber optic transceivers and cabling. Each port operates independently, supporting configurations ranging from simple dual-network connectivity to link aggregation and automatic failover.

Validated for use with the HP ProLiant DL385p Gen8, ML350e Gen8, ML350p Gen8, SL270s Gen8, SL4540 Gen8, and SL4545 G7, the 530T integrates with HP's server management ecosystem for monitoring and configuration. The dual 10Gb ports make it particularly well-suited for virtualized environments where multiple virtual machines share network resources, or for storage-heavy workloads where network throughput directly impacts performance. For administrators managing ProLiant Gen8 infrastructure who need to step up from Gigabit networking, the 530T provides a validated and cost-effective upgrade path.
