Jumbo frames
Permits up to a 9KB transmission unit (MTU)
Up to 17 message signaled interrupt (Extended)
802.1Q VLANs
Allows each physical port of the HP 331FLR to be separated into multiple virtual NICs for added network segmentation and enhanced security and performance.
TCP/IP stateless offloading
The HP 331FLR supports:
  • TCP

  • IP

  • UDP checksum offload

  • Large Send Offload (LSO)

Time synchronization (IEEE 1588)
Hardware assist for IEEE 1588 and IEEE 802.1AS time synchronization implementations for time sensitive applications.
Optimized forvirtualization
I/O virtualization support for VMware NetQueue and Microsoft VMQ help meet the performance demands of consolidated virtual workloads.
The HP 331FLR does not support SR-IOV ( Single Root - Input Output Virtualization)
Energy Efficient Ethernet
Compliant with IEEE 802.3az
HP Sea of Sensors 3D
Support for HP Sea of Sensors 3D which is a collection of 32 sensors that automatically track thermalactivity - heat - across the server
The upgrade from all six fans kickingon at one time to a new system where only one kicks on - the one in proximity of the area that startedheating up - thus reducing the amount of energy used for cooling
10/100/1000T twisted pair networks
Supports both 10 Mb/s and 100 Mb/s
FlexLOM slot compatibility
The HP 331FLR is compatible only with HP FlexLOM slot available on select HP ProLiant Gen8 Rack servers
PCI express compatibility
