## Long description

The HPE FlexFabric 10Gb 4-port FLR-T 57840S Adapter is a 10GBASE-T FlexibleLOM network adapter designed for HPE ProLiant Rack and HPE Apollo servers. It offers four 10 Gb Ethernet ports in a single FlexibleLOM form factor to increase throughput and reduce CPU overhead, making it suitable for virtualized and cloud environments where higher server I/O performance is required.
Advantages
This adapter delivers full line-rate 10 GbE throughput across four ports to accelerate server network performance and free CPU cycles for other tasks. It supports SR-IOV for efficient I/O virtualization and is compatible with VMware NetQueue and Microsoft VMQ to improve virtual machine network efficiency. With VLAN tagging support and NPAR partitioning, administrators can consolidate multiple connections onto one adapter and allocate bandwidth per partition, increasing networking flexibility in hybrid and virtual server infrastructures.
Key specifications
 Form factor: HPE FlexibleLOM (FLR-T)
 Speed: 10 GbE (10GBASE-T) per port
 Ports: 4
 Model: 57840S
 Virtualization: SR-IOV support
 Hypervisor features: VMware NetQueue, Microsoft VMQ
 Network features: VLAN tagging, NPAR (network partitioning)
 Target servers: HPE ProLiant Rack Servers, HPE Apollo Servers
How to use
Install the adapter into the FlexibleLOM slot of a compatible HPE ProLiant Rack or Apollo server according to HPE installation guidelines.
