Facebook Warm Storage – Next Generation Storage for Data Warehouse in Hadoop Ecosystem - Kestutis Patiejunas, Facebook
Introduction Very few companies run 24/7 clusters at the scale like Facebook using Hadoop/HDFS. As scale increases HDFS shows its limitations in scalability, performance and availability. HDFS was first designed 10+ years ago based on the assumptions that were valid in 2005. Over the years, numerous significant improvements have been made to the system. However storage, network and compute technology changed at different ratios during last decade. In this paper we describe Warm Storage - grounds up solution that exploits technology inflection points that exist in 2015 and we believe will continue into the future. We describe architecture and some of the implementation details of the novel and more efficient and available storage system optimized for DW workloads.

BoF: Logical DePop - Damien Le Moal, WDC
Some block storage device standards are working on a “logical depop" function which allows a system to decommission a defective physical element, e.g. a disk head or an SSD die or channel, reformat the device and continue using it with a reduced capacity. Such feature can allow reduced operation costs (delayed device replacement) but has the drawback of data loss (data under the remaining valid physical elements) and device downtime during re-formatting.

Online logical depop is another proposed new feature allowing retaining the device valid data and eliminating the need for a re-format. The basic idea is to introduce new commands for the host to discover the ranges of LBAs impacted by a defective element. Using this information, the host can take actions when an element failure event is suspected or reported by the device: deallocate the LBAs served by the defective element and operate the device in a thin-provisioned mode, amputate the LBAs or truncate the device LBA range to restore operation as a fully provisioned device with a lower capacity.

The goal of this BoF is to discuss the usefulness of such features and gather feedback from different application and system point of views for drafting a standard minimizing the impact of this feature on existing systems as well as enabling enhanced functionality for file systems,  device mapper drivers (including logical volume manager) and application level distributed storage systems (key value stores, object stores).

Froyo: Hassle-free Personal Array Management using XFS and DM - Andy Grover, Red Hat
LVM is a powerful, enterprise tool that uses Linux's Devicemapper subsystem to provide a wealth of possibilities for organizing and optimizing attached block storage. But, with power comes complexity. Dealing with errors, or even just making changes may cause infrequent users of the LVM tools to feel uneasy. Froyo provides a more managed storage solution -- feed it disks, and it gives you "a filesystem where your data is safe forever that never runs out of space".

Of course, under the covers are familiar technologies -- devicemapper and XFS, with Froyo pulling the strings. Andy Grover will talk about the development and implementation of Froyo, how it manages seamless online reconfiguration and monitoring of its member disks, and look forward to possible future improvements that leverage existing DM capabilities in new ways.

Tiering in GlusterFS: Hardware Config Considerations - Veda Shankar, Red Hat
Glusterfs's new tiering feature helps assure that data is available and accessible at the correct performance level thus satisfying both cost and performance concerns. This presentation will explain the Glusterfs's automated tiering feature followed by a live demonstration, and provide performance benchmark results from different hardware configurations. Glusterfs tiering monitors and identifies the activity level of the data and automatically promotes active data to hot SSD based storage and demotes inactive data to cold SATA based storage. Hence, the data movement can happen in either direction, based on the access frequency. The demonstration from Quanta/QCT labs (commodity x86 hardware) will show how to implement a hot tier based on SSD drives (optimized for performance) and attach it to an Erasure coded Glusterfs volume that is based on SATA drives (optimized for cost/capacity).

Arbiter based Replication in Gluster- without 3x Storage Cost and Zero Split-Brains! - Ravishankar N., Red Hat
Replication is an important aspect of any storage solution for backing up data and ensuring High Availability. This is non-trivial in case of distributed systems because achieving consistency and HA with only 2x replication is difficult as there is no notion of quorum (majority voting). But not everyone can afford to store 3x copies just to achieve consensus in case of a disagreement. So they end up using 2x replication but face frequent split-brains due to flaky networks etc. - a common complaint on the gluster-users mailing list.

The presentation will focus on the arbiter configuration in glusterFS replica volumes and explain how it provides the same consistency guarantees as that of a full blown 3 way replica but without the 3x storage cost. It describes how the arbitration logic works to prevents files from ending up in split-brain, how to deploy and monitor them.

Ganesha + Gluster scale out NFSv4 - Kaleb Keithley, Red Hat Gluster Storage
Many enterprises still heavily depend on NFS to access their data from different operating systems and applications. NFS-Ganesha is a user-space NFS server that supports NFSv3, NFSv4, NFSv4.1, as well as pNFS.

GlusterFS has now added NFS-Ganesha server to its NFS stack to eventually replace the 'native' Gluster-NFS server which supports only NFSv3. The integration with NFS-Ganesha now means additional protocol support for NFSv4+, and better security and authentication mechanisms for enterprise use. The recent release of GlusterFS-3.7 introduced clustered, multi-head, active/active NFS support using Pacemaker and Corosync for High Availability. There is also tighter integration with Gluster CLI to manage NFS-Ganesha exports. This presentation is aimed at providing a basic overview of the entire solution and step-by-step configuration.

GlusterD 2.0 - Managing Distributed File System Using a Centralized Store - Atin Mukherjee, Red Hat
In a typical distributed system managing n number of nodes in an effective way is always a challenge. Distributed systems always demands to meet CAP theorem which is really hard to meet with a good performance numbers. All the nodes participating in the cluster should have the consistent data which is one of the criteria of the CAP theorem. This could be achieved by keeping the configuration details across all the nodes in the cluster,
however this algorithm doesn’t scale (considering n X n number of exchange of information) and can end up having split brain situations. This could be avoided having distributed consistent store across m number of nodes (considered) as leaders where m < n. There are some existing technologies like etcd/consul which provides good abstraction and APIs for centralized store which can be consumed here.

Deploying pNFS over Distributed File Storage - Jiffin Tony Thottan, Red Hat
pNFS is the clustered solution provided by standard NFS protocol which allow NFS clients to access directly and parallelly the Storage device. This is achieved by the separation of metadata from the datapath. Therefore pNFS solution provides better bandwidth utilization, loading balancing across storage devices and significant performance improvement for I/O's. Now consider applying the pNFS over a Distributed Storage instead of native NFS. Here instead of talking to single server, pNFS client can interact directly with all the Storage Servers , i.e I/O distribution become much more effective and also avoids performance bottleneck with in a single server.

CoprHD is an open source software-defined storage controller and API platform. It enables policy-based management and cloud automation of storage resources for block, object and file storage providers, for both traditional storage arrays as well as scale-out storage software. In this talk, we will walk through scenarios where CoprHD can be useful, giving storage admins the ability to add new life to their legacy storage systems, as well as bridging the divide between old and new:

- You have client-server applications running on large servers that connect to centralized storage services. Your developers have created services running on OpenStack infrastructure, and you want to utilize your centralized storage with the same control plane
- You have several tiers of storage, with various parts being scale-out filesystems or object storage and the rest of it SAN arrays over iSCSI. You want to be able to set policies such that your applications utilize the correct tier of storage depending on the use case.

For each use case, we'll demonstrate a solution utilizing CoprHD, and then we'll walk through some best practices:

- When do you need an SDS controller, and when do you not
- I'm using Cinder, Manila, and/or Swift with OpenStack. When should I consider adding CoprHD to the mix?
- I have an orchestration framework and don't need yet another dashboard - how do I use a REST API?
