November 2 2018 Linux Piter #4
At Linux Piter, Dr. Felipe Franciosi discussed the performance challenges of storage virtualization. He talked about how SPDK is being leveraged to minimize the software overhead to record lows and shared performance data that show that it is possible for virtual machines to access Intel® Optane™ SSDs in under 10 microseconds for 4K I/O requests through virtio-scsi.
The Nutanix Bible
Explains the pros/cons of User vs. Kernel Space.
As devices have become faster (e.g. NVMe, Intel® Optane™, pMEM), the kernel and device interaction has become a bottleneck. To eliminate these bottlenecks, a lot of vendors are moving things out of the kernel to user space with polling and seeing much better results. Great examples of this are the Storage Performance Development Kit (SPDK) and Data Plane Development Kit (DPDK). These projects are geared at maximizing the performance and reducing latency as much as possible, and have shown great success.
AliCloud - High Performance Local SSD
Through close collaborations between AliCloud and SPDK, AliCloud offers one model (local SSD) among different kinds of cloud services. The AliCloud local SSD model is for critical applications like OLTP and NoSQL databases and designed with NVMe SSD and advanced SPDK storage techniques to achieve the extra high performance on single node like 480K max random read/write IOPS, 200us lower latency, 4GB/s max sequential read bandwidth, 2.4GB/s max sequential write bandwidth…

PolarFS: An Ultra-low Latency and Failure Resilient Distributed File System for Shared Storage Cloud Database
This paper describes how PolarFS uses emerging techniques like RDMA, NVMe SSDs and SPDK to reduce the end-to-end latency. The write latency of PolarFS is close to a local file system on SSD.
June 11 2018 14th International Workshop on Data Management
In this paper, SPDK was used to optimize the I/O path in Deuterony (a Log-Structured data caching DB) and reduce the cost of I/O operations by a third.
