Attala Systems showcased its implementation for cross-rack, lossy networks at the 2018 Flash Memory Summit yesterday. The Attala approach provides a way to utilize RoCE’s speed and low latency without the issues that have historically plagued its ability to be deployed on large-scale networks. The solution was developed with market leader Mellanox Technologies as a way to extend the reach of NVMe over RoCE (NVMe-oRoCE) networks with ordinary NICs and across lossy Layer 3 (L3) leaf-spine networks.
One of the most troublesome issues with RoCE-based protocols has been the need for the underlying networks to be lossless. While this is relatively easy for rack-scale deployments, it has historically been difficult to achieve on conventional layer three (L3) leaf-spine networks. By hardening the open-source SoftRoCE initiator, Attala’s own devices and providing SSDP-based discovery, Attala Systems has enabled its RoCE-based networking capability to operate on standard leaf-spine networks and with ordinary NICs. This allows cross-rack and ubiquitous deployment of NVMe-oRoCE’s industry-leading low latency and high performance on Ethernet networks at speeds from 10GbE to 100GbE and beyond.
“NVMe over RoCE has always been seen as the lowest latency, highest performance flavor of NVMe protocols. However, NVMe over RoCE’s need for lossless networks and specialized initiators has been somewhat of a limitation to its deployment,” said Taufik Ma, CEO of Attala Systems. “Attala Systems' approach allows their solution to be deployed on standard L3 leaf-spine networks without any special considerations.”
The cross-rack scalability of the Attala Systems solution is enabled by hardening the open-source SoftRoCE initiator driver and its own devices to gracefully handle packet-drops in a L3 leaf-spine networks – even those which do not support priority flow control (PFC) for achieve losslessness. This unshackles NVMe-over-RoCE solutions from the confines of a single rack and specific servers. Attala's solution also includes an autonomous Simple Service Discovery Protocol (SSDP) based discovery mechanism for newly added end-points, solving a common issue experienced by IP networks being utilized for scale-out infrastructure deployments. The community-hardened open-source SoftRoCE initiator driver runs on any ordinary NIC, enabling 100% compatibility with any Linux-based host server across the data center.
Attala Systems will be exhibiting their products at the 2018 Flash Memory Summit (FMS; http://www.flashmemorysummit.com) at Booth 848. FMS 2018 is being hosted at the Santa Clara Convention Center in Santa Clara, CA from August 7th to August 9th, 2018.
About Attala Systems
Founded in 2015 with offices in San Jose, California, Attala Systems is an early-stage technology company focused on the design and development of a new generation of storage and networking infrastructure based on the use of FPGAs and cloud-focused self-learning orchestration and provisioning software. By freeing storage architectures from the multiple levels of abstraction inherent in enterprise-based storage systems, Attala significantly improves system performance reduces operational costs for cloud storage providers and those with a need for high-performance, low latency storage systems.
