teuto.net, a cloud service provider (CSP) located in Bielefeld, Germany offering both public and private OpenStack clouds, has deployed Excelero’s NVMesh Server SAN along with Mellanox SN2100 switches to enable high performance with low-latency block storage in its teutoStack Cloud.
In noting Excelero was software-only, hardware-agnostic and partnered with both its long-time system integrator Boston Limited and with Mellanox, teuto.net commenced testing Excelero’s NVMesh Server SAN. The combined Excelero/Mellanox performance delivered 8,000 IOPS per virtual machine, according to Excelero, compared to 400 IOPS per VM with Ceph, such that teuto.net now recommends the Excelero-based teutoStack Cloud for customers with demanding private cloud OpenStack requirements.
“We based our teutoStack public Cloud around Ceph, so we know its many strengths – and challenges,” said Burkhard Noltensmeier, CEO of teuto.net. “Ceph is durable, scalable and fast for most uses, but with low-latency workloads like databases, Ceph’s performance lagged. By moving to Excelero and Mellanox for our teutoStack public cloud offering, we achieved stunning performance with an all-Linux implementation that is streamlined, resilient and automated. More importantly, we’re positioned to capture growth areas such as analytics, machine learning and AI where demanding databases require storage to match.”
teutoStack Cloud runs Excelero on SuperMicro servers from Boston Limited along with Mellanox ConnectX-4 and ConnectX-5 NICs running 2x25Gb Ethernet to each client node. It uses OpenStack Cinder to manage storage. With both Mellanox and Excelero’s support for Ubuntu, teuto.net has an all-Linux implementation for easy Integrated orchestration and monitoring.

“There’s tremendous interest in high-performance OpenStack storage as data centers move away from iSCSI and toward hardware-agnostic architectures, yet few vendors who can deliver what’s needed,” said Yaniv Romem, CTO and co-founder of Excelero. “We’re delighted that Excelero‘s NVMesh proved itself in teuto.net’s demanding private OpenStack cloud, and look forward to working with Mellanox and Boston Ltd. to help Teuto.net and others to deliver OpenStack to more markets.”
“Demanding IaaS or PaaS services need more than just performance from switches today – they also need easy automation and management,” said John F. Kim, director, storage marketing at Mellanox Technologies. “After trying another switch vendor that couldn’t meet their requirements, the Mellanox SN2100 was an obvious choice. Mellanox makes it easy to integrate its switches with Linux operations, so service providers like teuto.net.net can keep their priorities on running their business and not running their infrastructure.”
