NVMe Optional features for Cloud SSD customization
Live Stream - http://www.youtube.com/watch?v=nWCil5jWzjc

SSDs account for a growing share of the costs of large scale application deployments. The NAND in the SSD requires significant management by the flash controller to deal with media requirements. This management layer has significant impact on the usable cost of the SSD, the endurance, the reliability, and the consistency of performance. This has left large datacenters with a few options:
• Leverage commodity SSDs and try to make the workload SSD friendly and deal with sub optimal performance and endurance.
• Write detailed specifications for SSD vendors to respond to with custom cloud SSD products.
• Take on the work of designing an in-house SSD solution that needs to be modified for each NAND generation.

NVMe offers a way to leverage an open standard to enable applications and file system to have more direct control on SSD behavior without the need to design the particular issues for a current generation of NAND or other nonvolatile media. This session will go over the typical operation of a flash controller without application awareness, the optional features available in the NVMe standard that enable applications to direct SSD behavior and the potential benefits of this information to enable more usable capacity, lower cost NAND, and more predictable performance. The particular focus areas in the current and potential standards area are:
• Dataset Management & hinting
• Attribute pools & banding
• Directives - Streams, Garbage collection control
• Limited Retry
• Thin provisioning and variable physical capacity

Improving Software Defined Storage Ceph Performance While Reducing Costs
Live Stream - http://www.youtube.com/watch?v=G2w26xwJaUY

Seagate is developing innovative technologies through community collaboration. Seagate's advanced work with shingled magnetic recording HDDs (SMR) flash and caching software can satisfy both performance and cost/capacity objectives, at a lower TCO compared to traditional magnetic (CMR) HDD media. Red Hat Ceph Storage provides a unified, private cloud storage system designed for excellent performance, reliability, and scalability. Together, they enhance private cloud object storage by combining the ultra-low latency of flash with the capacity, space,power and cost effectiveness of SMR HDDs. This session will provide benchmark comparisons of Ceph on SMR with cache acceleration vs. on traditional HDDs.

AF-Media High Density All-flash Media Server
Live Stream - http://www.youtube.com/watch?v=indQVJUA5lQ

Abstract AF-Media server is a high density/high efficient all-flash storage server optimized for delivering media contents, developed by SK Telecom. As the leading telecom operator in Korea, SK Telecom was trying to find ways to enhance the service and decrease the TCO of its IPTV service. In order to achieve the goal, SK Telecom cooperated with its two subordinates; SK Hynix, a memory semiconductor of DRAM and Flash chips, and SK Broadband, an internet access and IPTV/CDN service provider. AF-Media was developed as a cooperation project among three companies. AF-Media S16 utilizes the latest Intel Xeon D SoC with 2.5" SATA SSDs and OCP mezzanine network card. The AF-Media features two hot-swappable compute nodes in a 2U form factor to provide an industry leading sixteen hot-swap 2.5" SSD drive bays or two PCIe SSD card slots for largest storage capacity per 1U compute node. Both drives and compute nodes are hot-swappable to facilitate ease of maintenance and minimize down time. To save power and space, the nodes share the same chassis and power supplies. Utilizing AF-Media S16 for its IPTV service, SK Telecom reduced power consumption and density by 80%, while providing better storage and network IO throughput compare to HDD based streaming server system. For this upcoming talk, SK Telecom would like to discuss about the design details, ecosystem, and the support received from OCP projects. As a token of our gratitude, SK Telecom recently upgraded the OCP member ship to Gold level, and expects to continue contributing to OCP for the future.

Cloud optimized HDD
Live Stream - http://www.youtube.com/watch?v=bt2ZRCtGR4c

Disks form the central element of Cloud-based storage, whose demand far outpaces the considerable rate of innovation in disks. Exponential growth in demand, already in progress for 15+ years, implies that most future disks will be in data centers and thus part of a large collection of disks. We describe the “collection view” of disks and how it and the focus on tail latency, driven by live services, place new and different requirements on disks. Beyond defining key metrics for data-center disks, we explore a range of new physical design options and changes to firmware that could improve these metrics.
