Ethernet Throughput. The HP NC364m is a HP BladeSystem c-Class network adapter providing four Gigabit Ethernet ports on a single card saving valuable server mezzanine slots for other purposes. The x4 PCI Express NC364m is supported on Integrity and ProLiant c-Class server blades in all mezzanine slots. For Integrity c-Class servers, it is the first network adapter mezzanine option available providing up to 16 Gigabit Ethernet ports per BL860c server, 128 ports per c7000 enclosure. For ProLiant, the NC364m is the second quad-port adapter option for c-Class allowing ProLiant customers a choice between an adapter that uses either an Intel or Broadcom controller.; The NC364m is ideal for virtualization, security, server consolidation, network segmentation, and other server applications requiring maximum throughput and port density. The total aggregate throughput of 4Gbps also meets the needs for customers desiring high bandwidth but are not yet ready to move to 10 Gigabit Ethernet. Ethernet Throughput. The HP NC364m Quad Port 1GbE BL-c Adapter has up to 2000 Mbps full duplex Ethernet transfer rate per port (8000 Mbps combined) delivering better network performance and improved response time by removing bottlenecks across the entire network. The NC364m support for 9K jumbo frames (also known as extended frames) permit a 9K byte transmission unit (MTU), which is six times the size of standard 1500 byte Ethernet frame. Supporting jumbo frames is a way to achieve higher throughput and better CPU utilization. IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the NC364m to be separated into multiple virtual NICs for added network segmentation and enhanced security and performance.
