OpenStack and Ceph case study at the University of AlabamaKamesh Pemmaraju
The University of Alabama at Birmingham gives scientists and researchers a massive, on-demand, virtual storage cloud using OpenStack and Ceph for less than $0.41 per gigabyte. This is a session at the OpenStack summit given by Kamesh Pemmaraju at Dell and John Paul at University of Alabama. This will detail how the university IT staff deployed a private storage cloud infrastructure using the Dell OpenStack cloud solution with Dell servers, storage, networking and OpenStack, and Inktank Ceph. After assessing a number of traditional storage scenarios, the University partnered with Dell and Inktank to architect a centralized cloud storage platform that was capable of scaling seamlessly and rapidly, was cost-effective, and that could leverage a single hardware infrastructure for the OpenStack compute and storage environment.
Intel - optimizing ceph performance by leveraging intel® optane™ and 3 d nand...inwin stack
Kenny Chang (張任伯) (Storage Solution Architect, Intel)
With the trend that Solid State Drive (SSD) becomes more affordable, more and more cloud providers are trying to provide high performance, highly reliable storage for their customers with SSDs. Ceph is becoming one of most open source scale-out storage solutions in worldwide market. More and more customers have strong demands that using SSD in Ceph to build high performance storage solutions for their Openstack clouds.
The disrupted Intel® Optane SSDs based on 3D Xpoint technology fills the performance gap between DRAM and NAND based SSD while the Intel® 3D NAND TLC is reducing cost gap between SSD and traditional spindle hard drive and makes it possible for all flash storage. In this session, we will
1) Discuss OpenStack storage Ceph reference design on the first Intel Optane (3D Xpoint) and P4500 TLC NAND based all-flash Ceph cluster, it delivers multi-million IOPS with extremely low latency as well as increase storage density with competitive dollar-per-gigabyte costs
2) Share Ceph bluestore tunings and optimizations, latency analysis, TCO model, IOPS/TB, IOPS/$ based on the reference architecture to demonstrate this high performance, cost effective solution.

OpenNebulaConf2018 - How Inoreader Migrated from Bare-Metal Containers to Ope...OpenNebula Project
See how Inoreader migrated from Bare-metal servers to OpenNebula + StorPool. Inoreader has reached a tipping point where it was no longer sustainable to add hardware servers to store the billions of articles that hundreds of thousands of users read every day across the globe. With OpenNebula and StorPool we can now utilize those servers far more efficiently and no longer worry about performance and downtime.

Netflix Open Source Meetup Season 4 Episode 2aspyker
In this episode, we will take a close look at 2 different approaches to high-throughput/low-latency data stores, developed by Netflix.
The first, EVCache, is a battle-tested distributed memcached-backed data store, optimized for the cloud. You will also hear about the road ahead for EVCache it evolves into an L1/L2 cache over RAM and SSDs.
The second, Dynomite, is a framework to make any non-distributed data-store, distributed. Netflix's first implementation of Dynomite is based on Redis.
Come learn about the products' features and hear from Thomson and Reuters, Diego Pacheco from Ilegra and other third party speakers, internal and external to Netflix, on how these products fit in their stack and roadmap.

Best Practices for Architecting VDI with Flash StorageRyan Snell
Classic presentation from 2012 demonstrating exactly where the storage performance bottleneck is for virtual desktop environments that hampers the ability to scale VDI for optimal end user computing experience. Whiptail being the best solution of course!
The flash market started out monolithically. Flash was a single media type (high performance, high endurance SLC flash). Flash systems also had a single purpose of accelerating the response time of high-end databases. But now there are several flash options. Users can choose between high performance flash or highly dense, medium performance flash systems. At the same time, high capacity hard disk drives are making a case to be the archival storage medium of choice. How does an IT professional choose?
