For datacenter applications requiring low-latency access to persistent storage, byte-addressable persistent memory (PM) technologies like 3D XPoint and MRAM are attractive solutions. Network-based access to PM, labeled here Persistent Memory over Fabrics (PMoF), is driven by data scalability and/or availability requirements. Remote Direct Memory Access (RDMA) network protocols are a good match for PMoF, allowing direct RDMA data reads or writes from/to remote PM. However, the completion of an RDMA Write at the sending node offers no guarantee that data has reached persistence at the target.
Join the Networking Storage Forum (NSF) on October 25, 2018 for out next live webcast, Extending RDMA for Persistent Memory over Fabrics. In this webcast, we will outline extensions to RDMA protocols that confirm such persistence and additionally can order successive writes to different memories within the target system. Learn:
- Why we can’t just treat PM just like traditional storage or volatile memory
- What happens when you write to memory over RDMA
- Which programming model and protocol changes are required for PMoF
- How proposed RDMA extensions for PM would work
We believe this webcast will appeal to developers of low-latency and/or high-availability datacenter storage applications and be of interest to datacenter developers, administrators and users. I encourage you to register today. Our NSF experts will be on hand to answer you questions. We look forward to your joining us on October 25th.
