GlusterFS Cinder integration presented at GlusterNight Paris event @ Openstac...Deepak Shetty
This was a brief presentation talking about the current state of affairs on the GlusterFS Cinder Integration in the GlusterNight Paris event organised by Red Hat for GlusterFS community members, as part of the Openstack Paris Nov. 2014
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
The primary requirements for OpenStack based clouds (public, private or hybrid) is that they must be massively scalable and highly available. There are a number of interrelated concepts which make the understanding and implementation of HA complex. The potential for not implementing HA correctly would be disastrous.
This session was presented at the OpenStack Meetup in Boston Feb 2014. We discussed interrelated concepts as a basis for implementing HA and examples of HA for MySQL, Rabbit MQ and the OpenStack APIs primarily using Keepalived, VRRP and HAProxy which will reinforce the concepts and show how to connect the dots.

SOCRadar Research Team: Latest Activities of IntelBrokerSOCRadar
The European Union Agency for Law Enforcement Cooperation (Europol) has suffered an alleged data breach after a notorious threat actor claimed to have exfiltrated data from its systems. Infamous data leaker IntelBroker posted on the even more infamous BreachForums hacking forum, saying that Europol suffered a data breach this month.
The alleged breach affected Europol agencies CCSE, EC3, Europol Platform for Experts, Law Enforcement Forum, and SIRIUS. Infiltration of these entities can disrupt ongoing investigations and compromise sensitive intelligence shared among international law enforcement agencies.
However, this is neither the first nor the last activity of IntekBroker. We have compiled for you what happened in the last few days. To track such hacker activities on dark web sources like hacker forums, private Telegram channels, and other hidden platforms where cyber threats often originate, you can check SOCRadar’s Dark Web News.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

What is GlusterFS?
● A general purpose scale-out distributed file
system.
● Aggregates storage exports over network
interconnect to provide a single unified namespace.
● Filesystem is stackable and completely in
userspace.
● Layered on disk file systems that support extended
attributes.

GlusterFS Architecture – Foundations
● Software only, runs on commodity hardware
● No external metadata servers
● Scale-out with Elasticity
● Extensible and modular
● Deployment agnostic
● Unified access
● Largely POSIX compliant
7. GlusterFS concepts – Trusted Storage Pool
● Trusted Storage Pool (cluster) is a collection of storage
servers.
● Trusted Storage Pool is formed by invitation – “probe” a
new member from the cluster and not vice versa.
● Membership information used for determining quorum.
● Members can be dynamically added and removed from
the pool.

8. GlusterFS concepts - Bricks
A brick is the combination of a node and an export directory – for e.g. hostname:/dir
Each brick inherits limits of the underlying filesystem
No limit on the number bricks per node
Ideally, each brick in a cluster should be of the same size

GlusterFS concepts - Volumes
● A volume is a logical collection of bricks.
● Volume is identified by an administrator provided name.
● Volume is a mountable entity and the volume name is
provided at the time of mounting.
– mount -t glusterfs server1:/<volname> /my/mnt/point
● Bricks from the same node can be part of different
volumes
11. 12/17/14
Volume Types
➢Type of a volume is specified at the time of volume
creation
➢ Volume type determines how and where data is
placed
➢ Following volume types are supported in
glusterfs:
a) Distribute
b) Stripe
c) Replication
d) Distributed Replicate
e) Striped Replicate
f) Distributed Striped Replicate
12. 12/17/14
Distributed Volume
➢Distributes files across various bricks of the volume.
➢Directories are present on all bricks of the volume.
➢Single brick failure will result in loss of data availability.
➢Removes the need for an external meta data server.
13. How does a distributed volume work?
➢ Uses Davies-Meyer hash algorithm.
➢ A 32-bit hash space is divided into N ranges for N bricks
➢ At the time of directory creation, a range is assigned to each
directory.
➢ During a file creation or retrieval, hash is computed on the file
name. This hash value is used to locate or place the file.
➢Different directories in the same brick end up with different
hash ranges.
12/17/14
14. 12/17/14
Replicated Volume
● Synchronous replication of all directory and file
updates.
● Provides high availability of data when node
failures occur.
● Transaction driven for ensuring consistency.
● Changelogs maintained for re-conciliation.
● Any number of replicas can be configured.
16. 12/17/14
Distributed Replicated Volume
● Distribute files across replicated bricks
● Number of bricks must be a multiple of the replica count
● Ordering of bricks in volume definition matters
● Scaling and high availability
● Reads get load balanced.
● Most preferred model of deployment currently.
18. 12/17/14
Striped Volume
● Files are striped into chunks and placed in various
bricks.
● Recommended only when very large files greater than
the size of the disks are present.
● A brick failure can result in data loss. Redundancy with
replication is highly recommended (striped replicated
volumes).
19. 12/17/14
Elastic Volume Management
Application transparent operations that can be performed
in the storage layer.
● Addition of Bricks to a volume
● Remove brick from a volume
● Rebalance data spread within a volume
● Replace a brick in a volume
● Performance / Functionality tuning
20. 12/17/14
Access Mechanisms
Gluster volumes can be accessed via the following
mechanisms:
– FUSE based Native protocol
– NFSv3 and v4
– SMB
– libgfapi
– ReST/HTTP
– HDFS
22. 12/17/14
Translators in GlusterFS
● Building blocks for a GlusterFS process.
● Based on Translators in GNU HURD.
● Each translator is a functional unit.
● Translators can be stacked together for
achieving desired functionality.
● Translators are deployment agnostic – can be
loaded in either the client or server stacks.
26. 12/17/14
Use Cases - current
● Unstructured data storage
● Archival
● Disaster Recovery
● Virtual Machine Image Store
● Cloud Storage for Service Providers
● Content Cloud
● Big Data
● Semi-structured & Structured data
