The network decides how much of your GPU you actually use
In GPU clusters the network decides how much of that compute you actually get to use. Distributed training synchronises gradients at every step; a few microseconds of latency or a single dropped packet in the fabric means expensive GPUs sitting idle. As the cluster grows, that loss does not scale linearly — it compounds.
Mevasis supplies the network layer of HPC and AI infrastructure end to end: InfiniBand spines and adapters, optical modules, lossless RoCE Ethernet fabrics and structured cabling. We do not simply sell the parts; we design the topology, commission it and hand it over with a measurement report.
The catalogue below covers the connectivity layer of HPC infrastructure, from the compute network through storage networking to structured cabling. Every product family includes technical specifications, connectivity scenarios and direct access to the manufacturer’s documentation.

Yes. Mevasis is the authorised dealer in Türkiye for the HPC networking products listed here; hardware ships under manufacturer warranty, invoiced, through a traceable supply chain.
In HPC networking, price depends on configuration, quantity, lead time and project scope. Instead of a fixed list price we prepare a quote for your specific requirement. Fill in the form on a product page and our team typically responds the same business day.
Hardware-only supply is possible. That said, a misconfigured fabric topology, the wrong optics or mismatched firmware cost real performance, so we recommend at least a design review.
A few business days for stocked items; project-specific configurations follow the manufacturer's supply schedule. The quote states the current lead time per line item.
Share your current switch models, HCA firmware versions and cabling inventory, and we produce the compatible part list and any required firmware updates. This verification is part of the quoting process and is free of charge.
