The document discusses considerations for building a private cloud. It defines a private cloud as generally smaller than a public cloud, with less than 100 physical servers. It emphasizes the importance of building the private cloud with the intended future scale and needs in mind regarding hardware, networking, and growth. Specifically, it recommends carefully planning the host, fixed, and floating (if used) networks to allow for easy expansion.
Supporting and Using EC2/CIMI on top of Cloud Environments via DeltacloudOved Ourfali
In this presentation I'll describe some standard and common cloud APIs such as EC2 and CIMI, and show how one can use Deltacloud in
order to support them on top ofcloud environments. As an example, I'll show how to add this support and use it on top of the oVirt engine.
This IBM Redpaper provides a brief overview of OpenStack and a basic familiarity of its usage with the IBM XIV Storage System Gen3. The illustration scenario that is presented uses the OpenStack Folsom release implementation IaaS with Ubuntu Linux servers and the IBM Storage Driver for OpenStack. For more information on IBM Storage Systems, visit http://ibm.co/LIg7gk.

Building highly efficient cloud infrastructure, and lessons learned from real deployments: The session will cover how to build converged cloud solution based on industry standard components and open source software, to deliver the best cost/performance, lowest $/GB storage, and lowest $/VM, and the right balance of compute, network, and storage resources. This is based on the speaker experience of working with multiple OpenStack based cloud providers, integrators, and internal implementation of OpenStack private cloud in Mellanox The session will also discuss various software defined storage (SDS) and commercial options, what’s the benefit of one vs the other, how to efficiently combine SSD & HDD, and expiriance with BigData and Hadoop applications, will cover latest innovations in the space of high-performance networking and storage (VXLAN in hardware, DPDK/NFV, Cinder acceleration, Ceph over RDMA, ..) , and will go over a concrete for high-density, high-perform
A technical overview of the Arteris Ncore cache coherent interconnect IP for use in heterogeneous cache coherent systems-on-chip (SoC). To enable heterogeneous cache coherency, the IP enables multiple coherence models, multiple configurable snoop filters, and multiple proxy caches.

Backup / Restore to Cloud Storage with esXpress and CloudArray softwareTwinStrata
The following presentation provides a functional overview on:
How PHD esXpress backup software together with CloudArray work seamlessly to protect VMware ESX and ESXi environments
This solution provides an economic and highly reliable storage tier for offsite data backup and replication without the logistics and cost of tape transport.
Liberati dal sovraccarico e dalle limitazioni dell’infrastruttura locale. Sfrutta risorse illimitate per ottenere scalabilità per i processi HPC (High Performance Computing), per analizzare dati su vasta scala, eseguire simulazioni e modelli finanziari e sperimentare riducendo il tempo di immissione sul mercato.
NVMe and NVMe over fabrics promises to change the flash and networking industry. NVMe enables storage systems to tap into the full potential of flash storage and NVMe allows those systems to deliver in-server latencies. NVMe will fundamentally change storage. Are you ready?

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.
