Cavium ThunderX 64bit 48-core ARM Server enabling the 5G mobile future, next gen cloud/datacenter and NFV

Posted by Charbax – February 24, 2016

Cavium’s ThunderX 48-core ARMv8 64bit SoC is being implemented in dozens of ARM Server designs, by partners as Pegatron, Asus, Mitac, Gigabyte, Wiwynn, Acer and even for for super computing by E4 and Cray. Cavium and their software partners have optimized their ARM Server platform for variety of workloads, including NFV (Network Function Virtualization), Cloud RAN (Radio Access Network) for Virtualizing the access network, moving all the physical base stations to the cloud, which will save the industry a lot of money, hyperscale datacenter, web hosting like RunAbove (a subsidiary of OVH) at, Ceph storage clusters. This can only be done using ARM and Cavium ThunderX SoC processors, providing a much better TCO (Total Cost of Ownership) and efficient alternative to Intel x86. Cavium and partners, as Linaro and the open source community also are showing progress in the OPNFV, OpenStack, ODP (Open Data Plane), DPDK,, etc. for the networking and telecom industry.

Posted by Charbax – February 7, 2016

Functional demonstration of ODP-OpenvSwitch (ODP-OVS) running on ThunderX. ODP-OVS to process the upd pkt in loopback way on 10G port. Pkt generator pumps 10G traffic to ODP-OVS port. ODP-OVS receives pkts, validates pkt hash from ovs flow_table and then loopback to same port at 10G line rate.

Gigabyte H260-T70 ARM Server with Cavium ThunderX dual-socket 96-core/board, 384-core/2U server

Posted by Charbax – June 3, 2015

Gigabyte shows their "fastest ARM Server in the world" solution, packing 384 cores into a standard 2U. Big cloud companies like Google, Facebook, Amazon could buy these to fill up their datacers with 11 thousand or 15 thousand of them. Gigabyte's ARM Server product manager talks about the performance, the features compared to the old fashioned Intel x86 servers, the power consumption is much lower. Gigabyte will launch the mass production in November, now providing samples for validation and testing by their big cloud company customers around the world. The 48-core ARM ThunderX Processor uses about 95W, while the comparative-performance Intel x86 based server processor consumes 145W, totally the saving is about 400W per 2U system, which means a potential saving of 8000W power per server rack. Gigabyte started using ThunderX in their R120-T30 single-socket server, moving to the dual socket design to be ready for taking over the massive cloud computing market.
