Abstract Changes in the May 5 update: Added SR645 and SR665 to the server
support table - Server support section Added OS support for ThinkSystem
Broadcom 5719 1GbE RJ45 4-port OCP Ethernet Adapter, 4XC7A08235 - Operating
system support section Did you know? The NetXtreme Quad Port Ethernet Adapter is
an ideal way to implement a virtualization solution using your existing Gigabit
Ethernet network. With four copper-based Gigabit ports on a single PCI Express
2.0 x4 interface, the adapter provides the density and capacity you need to
support large numbers of virtualized systems on one server. Features and
specifications The adapters have the following features: One, two, or four
10/100/1000 copper ports with RJ45 for Cat 5e/6 cabling Full line-rate
performance across all ports Standard form factor adapters, either PCIe low
profile or OCP 3.0 SFF PCI Express 2.0 host interface Jumbo Frames support
(9600 bytes frames) Wake-on-LAN (WoL) support IEEE 802.1q VLAN support -
provides enhanced network management and efficiency I/O virtualization (IOV)
support for VMWare NetQueue and Microsoft VMQ - improves network performance in
virtualized environments IEEE 802.3x flow control support IEEE 802.3ad link
aggregation support IEEE 802.3 auto-negotiation support Automatic MDI
crossover Receive and transmit side scaling TCP, IP, and UDP checksum offload
Message Signaled Interrupts (MSI) and MSI-X support - Maximizes server
processing performance by reducing CPU overhead and lowering interrupt latency
On-chip temperature monitor (NetXteme I only) IEEE 802.3az Energy Efficient
Ethernet (EEE) compliant - Reduces adapter power consumption by up to 42%
through intelligent adaptive power management, adjusting power based on data
traffic load. (NetXtreme I only) IEEE 802.3z (Clause 30) - Statistics for SNMP
MIB II, Ethernet like MIB, and Ethernet MIB (NetXtreme I only) IEEE 1588
Precision Time Control and 802.1AS time synchronization support - Provides
greater accuracy of data packet delivery within the network (NetXtreme I only)
Management using Broadcom Advanced Control Suite (BACS), Windows Management
Instrumentation (WMI), and Broadcom Management API (BMAPI) The following table
compares the features of the cards.
