ReFlex: Remote ~= local Flash in the datacenter

Opis:

Remote (over the network) access to NVMe Flash enables flexible scaling and high utilization of Flash storage capacity and throughput within a datacenter. However, existing systems for remote Flash either introduce significant performance overheads or fail to isolate multiple remote clients sharing each Flash device.

This talk presents ReFlex: a software-based system for remote Flash access that provides nearly identical performance to accessing local Flash. ReFlex uses a dataplane kernel to closely integrate networking and storage processing to achieve low latency and high throughput with low resource requirements. ReFlex also uses a novel I/O scheduler to enforce tail latency and throughput service-level objectives (SLOs) for thousands of remote clients. ReFlex allows applications to use remote Flash while maintaining their original performance with local Flash.
