Quad-port 1 gigabit ethernet throughput
|
HP 331T adapter provides 2,000 Mb/s full duplex Ethernet transfer rate per port (8 Gb/s aggregate full duplex) delivers outstanding network performance that improves response time and removes bottlenecks. The total aggregate throughput of 8 Gb/s in full-duplex mode also meets the needs for customers desiring high bandwidth but are not yet ready to move to 10 Gigabit Ethernet.
|
|
Jumbo frames
|
The 331T adapter support for jumbo frames (also known as extended frames) permits up to a 9KB transmission unit (MTU) when running Ethernet, which is over five times the size of standard 1500-byte Ethernet frame. Jumbo frames can help achieve higher throughput and better CPU utilization and are particularly useful for database transfer and tape backup operations.
|
|
MSI and MSI-X
|
Up to 17 Message Signaled Interrupt (Extended) provides performance benefits for multi-core servers by load balancing interrupts between CPUs/cores.
|
|
802.1Q VLANs
|
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the HP 331T to be separated into multiple virtual NICs for added network segmentation and enhanced security and performance. VLANs increase security by isolating traffic between users. Limiting the broadcast traffic to within the same VLAN domain also improves performance.
|
|
TCP/IP stateless offloading
|
For overall improved system response, the 331T supports standard TCP/IP offloading techniques including:
|
|
Time synchronization
|
Hardware assists for IEEE 1588 and IEEE 802.1AS time synchronization implementations for time sensitive applications.
|
|
Optimized for virtualization
|
I/O Virtualization support for VMware NetQueue and Microsoft VMQ help meet the performance demands of consolidated virtual workloads.
|
|
HP sea of sensors 3D
|
Support for HP Sea of Sensors 3D Technology which is a collection of 32 sensors that automatically track thermal activity – heat – across the server. When temperatures get too high, sensors can kick on fans and make other adjustments to reduce energy usage.
|
|
Energy efficient ethernet
|
Compliant with IEEE 802.3az, featuring advanced power savings features throttles power usage with network load activity.
|
|
Versatility 10/100/1000T twisted pair networks
|
In addition to Gigabit Ethernet, the HP 331T adapter supports both 10 Mb/s and 100 Mb/s providing compatibility with Ethernet and Fast Ethernet twisted pair networks.
|
|
Full and half height brackets
|
The HP331T adapter ships with a pre-installed full height bracket and a half height bracket is also supplied to ensure trouble free installation. The included quick install card guides the user in the bracket exchange process
|
|
x4/x8/x16 PCI express compatibility
|
The x4 PCI Express interface on the HP 331T is compatible with x4, x8, and x16 PCI slots. If installed in a x8 or x16 slot, the adapter will operate at the x4 speed.
|
|
Auto-negotiation
|
The HP 331T automatically senses the speed of the device to which it is attached. It also automatically configures for full duplex, depending on the duplex mode of the switch, hub, or router connected to the adapter.
|
|
Management support
|
Like all HP server adapters, the HP 331T ships with drivers and agents that can be managed from HP Systems Insight Manager, as well as using any other management application that supports SNMP.
|
|
Server integration
|
The HP 331T is a completely integrated, tested, and qualified solution that is optimized for HP servers. HP validates a wide variety of major operating systems drivers with the network drivers plus provide a central interface to simplify network management.
|
|
Configuration utilities
|
Each HP 331T ships with a suite of operating system-tailored configuration utilities that allow the user to enable initial diagnostics and configure adapter teaming. This includes a patented teaming GUI for Microsoft Windows operating systems.
