HPE

817749-B21-Excellent

被困在10Gbps网络流量中?是时候通过HPE 25GbE适配器进入快车道了。随着移动数据和视频的量增加以及频繁访问的次数增加,传统技术正在努力处理增加的吞吐量,并且缺乏成本效益的扩展能力。

当前管理不断增加的数据中心流量的方法需要更高的带宽,这是经济上难以承受的,使组织无法轻松地随着需求的增长而增长。HPE以太网25Gb 2端口640 FLR-SFP28适配器是专为满足更高带宽需求的电信、服务提供商、金融机构和企业而设计的,采用FlexibleLOM形式因子,适用于选择的HPE ProLiant Gen9 Server DL系列机架和HPE Apollo服务器,提供高性能解决方案。

特点

应对对Overlay网络的日益增长的需求

HPE以太网25Gb 2端口640 FLR-SFP28适配器通过对VXLAN和NVGRE的隧道卸载支持,减少了在主机性能上的Overlay网络的影响,增加了VM迁移的灵活性并最大程度地减少了对性能的影响。

将虚拟覆盖网络层与物理NIC性能解耦。

自动协商至10GbE以进行即时未来验证。

通过以太网收敛RDMA(RoCE)更高效快速地发送数据

HPE以太网25Gb 2端口640 FLR-SFP28适配器绕过TCP/IP堆栈,并消除数据复制步骤,从而降低整体延迟,提供加速性能,适用于Microsoft Hyper-V Live Migration、Microsoft SQL和Microsoft SharePoint等应用程序,支持SMB Direct。

RDMA over Converged Ethernet(RoCE)可实现更高的服务器效率和更低的延迟。

使用消息加速器(VMA)降低延迟,提高吞吐量

HPE以太网25Gb 2端口640 FLR-SFP28适配器降低系统延迟,提高性能,特别适用于高频交易操作,同时保持高消息速率和数百个同时连接。

包含VMA,这是一种包含许多好处的固件,例如更低的延迟、更高的吞吐量、改进的CPU利用率以及用户数据与硬件之间的最小缓冲区复制。
