Synology E10M20-T1

The Synology LAN 1x10GbE RJ45 network card is designed to provide a fast and efficient network connection with support for up to 10Gb/s, which is ideal for expanding your Synology NAS device. With 10GbE technology, this network card brings new possibilities to your home or office network, enabling smoother transfers of large data volumes and better system responsiveness under high data demands. The card is equipped with a PCIe 3.0 x8 interface, which makes it easy to install. The Synology E10M20-T1 is compatible with a wide range of network standards, including IEEE 802.3an/bz (10GBASE-T/NBASE-T), IEEE 802.3ab (Gigabit Ethernet), IEEE 802.3x (Flow Control), and IEEE 802.3ad (Link Aggregation). Link Aggregation support (IEEE 802.3ad) lets you combine multiple network ports to increase bandwidth and ensure redundancy. However, for Link Aggregation to function correctly, your network switch must also support the LACP (Link Aggregation Control Protocol). Flow control (IEEE 802.3x) helps prevent network congestion by letting network devices manage the data flow. This function is bidirectional and also requires support on both ends of the network connection. With support for a wide range of network standards and advanced features, the Synology E10M20-T1 network card is a powerful and flexible solution for upgrading your network.

The Synology E10M20-T1 network card supports additional features

You can install Synology SNV3000 series NVMe SSDs on the E10M20-T1 network card. The Synology E10M20-T1 network card is equipped with a range of advanced features to optimise network performance and efficiency. Support for Jumbo Frames up to 9kB allows for the transfer of larger data packets, which reduces packet processing overhead and increases network throughput. However, your router must also support the same function. Auto-negotiation between 100Mb/s, 1Gb/s, 2.5Gb/s, 5Gb/s, and 10Gb/s ensures compatibility with various network environments and enables smooth operation even when the connection speed changes. The TCP/UDP/IP Checksum Offloading feature transfers checksum calculation and verification to the network card, thereby reducing CPU load. TCP Segmentation Offload (TSO) and Generic Segmentation Offload (GSO) further optimise CPU usage by splitting large frames into smaller units before sending. Large Send Offload (LSO) improves data sending performance by enabling the transfer of larger frames. Receive Side Scaling (RSS) and Generic Receive Offload (GRO) increase data reception efficiency by distributing the load among multiple processor cores and merging multiple incoming packets into a single larger frame.
