On their official blog:
Over the last several months, SwiftStack has been busy helping two large autonomous vehicle customers. These data pipelines are distributed across edge (vehicle sensors) to core (data center) to cloud/multi-cloud locations, and are challenged with ingest, labeling, training, inferencing, and retaining data at scale. [...] one deployment is handling more than a petabyte of data per week, with four thousand GPU cores from NVIDIA DGX-1 servers fed with 100 GB/s of throughput from SwiftStack cluster.
I suspect the task-queue expirer could be helpful at this. Although, if you're uploading 1 PB per week, it takes about a year to fill out a cluster as big as Turkcell's.
Apparently the actual storage is provided by Cisco UCS S3260. Some of our customers use Cisco UCS to run Swift too. I always thought about Cisco as a networking company, but it's different nowadays.
