1 ATTO FastFrame 40Gb Ethernet Features &
FastFrame 40Gb Ethernet Adapters provides high-performance, low-latency 40 Gbps Ethernet connectivity.
ATTO's 40Gb Ethernet Adapter solutions are single-
and dual-channel PCIe 3.0 x8 solutions offering near
line-rate throughput via the usage of Remote Direct
Memory Access (RDMA), specifically the RDMA over
Converged Ethernet (RoCE) protocol. Simultaneously
improving CPU utilization and throughput by allowing
for direct memory transfers bypassing the CPU and
TCP/IP stacks, RoCE is the key for any user of 40Gb
Ethernet looking to take full advantage of 40Gb
bandwidth. ATTO's 40Gb Ethernet FastFrame cards
come in both optical (with QSFP+s included) and
Direct-Attached options, providing flexibility for
numerous installations.
Driver support for 40Gb Ethernet includes multiple
installations of both Windows and Linux.
Getting started
In general, to install the ATTO Network Interface
Adapter, you must:
1
Ensure you have the equipment and software
you need for the installation:
• FastFrame 40Gb Ethernet Adapter
• A computer with an available expansion slot
Note
Install your FastFrame NIC into a PCIe 3.0
x8 expansion slot for best performance
• Cables

Overview
FastFrame 40Gb NICs provide high-performance,
low-latency 40 Gigabit Ethernet connectivity. Built
using silicon provided by the industry's leader in low
latency Ethernet, Mellanox, ATTO FastFrame NICs
provide the most performance and the lowest
utilization of CPU cycles, in addition to industry-
leading power efficiency. Supporting numerous
protocols from standard TCP/IP to NFS RDMA to
iSCSI, ATTO's FastFrame 40Gb NICs are available in
single- and dual-port configurations, with optical
QSFP+ or direct attached copper support.
• Provides sufficient bandwidth for numerous
streams of uncompressed 4k video, in addition
to uncompressed 8k video
• Industry-leading latency allows for more usage
of 40GbE pipe. NICs without RDMA support top
out at about 21Gbps performance; with ATTO's
RDMA implementation, performance can reach
near line-rate at 39Gbps.
• Lowest power utilization profile and CPU
utilization profile on market combines to provide
highest ROI (in terms of gigabytes transferred
per dollar spent on power) among 40GbE NICs
on the market.
