The HP NC364m is a HP Blade System c-Class network adapter providing four Gigabit Ethernet ports on a single card saving valuable server mezzanine slots for other purposes. The x 4 PCI Express NC364m is supported on Integrity & Pro Liant 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 c 7000 enclosure. For Pro Liant, the NC364m is the second quad-port adapter option for c-Class allowing Pro Liant 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, & other server applications requiring maximum throughput & port density. The total aggregate throughput of 4 Gbps 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 1 Gb E BL-c Adapter has up to 2000 Mbps full duplex Ethernet transfer rate per port (8000 Mbps combined) delivering better network performance & enhanced 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 & 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 & enhanced security & performance.
