It has been some time since we covered a new DPU, but the new Xsight Labs E1 DPU looks cool. The DPU comes with either 32 or 64 Arm Neoverse N2 cores, up to 2x 400Gbps networking, and 32x configurable PCIe Gen5 x16 lanes. Xsight Labs E1 DPU OverviewThe Xsight Labs E1 DPU is designed to be very flexible. Built around Arm Neoverse N2 cores, the SoC has a number of accelerators as well as high-speed SerDes. There is also a DDR5 memory complex and more onboard. Here is the chip’s block diagram.

At Computex 2025, our team spotted five Broadcom Tomahawk 6 switches. Of those, only two were allowed to be photographed since theĀ Broadcom Tomahawk 6 was still under embargo until this week. Those two did not list the Tomahawk 6 at the time, instead using generic terms, but we thought we would at least share some photos. As a quick recap, the new Broadcom Tomahawk 6 has up to 102.4Tbps of bandwidth or, in other terms, it can support 64-ports of 1.6TbE. Let us get to the switches.

Something that we covered in the video, but we did not show photos of in our originalĀ MikroTik RDS2216-2XG-4S+4XS-2XQ Review, was the two internal M.2 SATA SSD spaces. We thought we would at least show what we did with these. We installed two SiliconPower A55 SATA SSDs but found something interesting.

Today, we are taking a look at the QNAP QNA-T310G1S Thunderbolt 3 to 10G adapter. We have been using this one as a quick connection for many of the systems we have that need to get on SFP+ fiber networks. In the spirit of theĀ Sonnet Solo 10G Thunderbolt 3 10GbE Adapter quick look, we wanted to show another adapter we use in the lab. QNAP QNA-T310G1S Thunderbolt 3 to 10G Adapter Quick LookOne of the two important sides of the adapter is the SFP+ cage side.

A few days ago we posted our Going 800Gbps at up to 1000km with the Marvell COLORZ 800 piece and in that we briefly showed inside two other modules. One we already featured in Inside a 100G QSFP28 DAC. The other, the 100G SR4 QSFP28 module is certainly more complex than the 100G QSFP28 DAC, so we wanted to show that as well. Usually it is not the best idea to take apart optical modules if you want to ensure they keep working, so we decided to sacrifice one for STH.
