ICCLab presents Interoperability and APIs in OpenStack @ EGI Technical Forum, Cloud Interoperability Week

The ICCLab was invited to give a talk on Interoperability and APIs in OpenStack at EGI Technical Forum which was co-located with Cloud Interoperability Week. The workshop and hands-on tutorial sessions took place between September 18-20, 2013 in the beautiful city of Madrid.

The presentation sessions were followed by panel discussion where all the speakers entertained several questions from the audience. There was substantial interest in the audience with respect to OCCI development roadmap and questions were also raised on suitability of one cloud standard against another.

In the tutorial sessions that followed the workshop, there were several projects that demonstrated their use of the OCCI standard. Notable among them were OpenStack, OpenNebula, and CompatibleOne.

COST IC0906 WiNeMO – 24-25 September, Ohrid, Macedonia

COST (European Cooperation in Science and Technology) is one of the longest-running European frameworks. The leading objective of this project is to support European research and innovation by encouraging scientific developments and integration of research communities.

On the 24th and 25th of September, the members of this project held one of the regular annual’s meetings in the beautiful city of Ohrid, Macedonia. More info can be found here.uist-winemo-image

The meeting was opened by proposing and voting for the next meeting’s date and venue. London will host the upcoming event and the proposed dates are: 21.04.2014 and 28.04.2014.

Next, a book in preparation was announced. WiNeMO Springer Book CFP has been extended to increase the quality and address the missing subjects. This offers an opportunity to the members of the ICCLab to contribute to the chapters: “Testbed, prototypes and measurements” or “Economical – business aspects“. Potential contributors should email to Ivan Ganchev (, Marilia Curado ( or Andreas Kassler (

Dates of interest:

Abstract submission: 15th Oct 2013

Full chapter submission: 31 Dec 2013

Full chapter notification: 15th Feb 2014

The Horizon 2020 was discussed. It is the new EU project initiative after the FP7 expires by the end of this year. Some of the relevant topics in focus of this initiative include: smart & inclusive growth, sustainable growth, natural resources, security and citizenship etc. It will have a six years duration (2014-2020) and will count with 80 billion Euros.

Several interesting talks were presented form the area of Wireless Networking for Moving Objects (WiNeMO). On behalf of Thomas M. Bohnert and the ICCLab, Irena Trajkovska gave a talk entitled “P2P Multicast in KIARA with OpenFlow based QoS“, which raised the attention for interesting questions and comments.

The InIT BladeCenter Lab

Complimenting the ICCLab cloud computing lab, the InIT operates and runs 2 BladeCenter infrastructure environments, based on IBM Blade-server technology.

These environments have different purposes:

  • 1 productive environment for projects, teaching and training systems (running on VMware vSphere v5.0 and operated via a vCenter 5 management system)
  • 1 test and training environment for practical exercises (different hypervisor configurations, as required during lab exercises)

The systems consist of IBM Blade servers, corresponding BladeCenter chassis and are connected to IBM SAN storage networks that are linked via fiberoptic switches to deliver a maximum of flexibility and performance for each environment. Both environments can be operated and run independent from each other, at different physical locations.

Hard-/Software Infrastructure and Virtualization Layers

The productive InIT BladeCenter environment consists of 7 IBM HS 22 Blade systems, each with 192 GB RAM, 2 Xeon processors per system and are linked to a 8Gbit fiberoptic network storage switch.

They are running on  VMware vSphere v5.0 hypervisor software for virtualization and a are operated via vCenter v5 as management platform.

The productive environment has 3 IBM DS 3512 SAN storage units available, 2 x 12 TB storage space and 1 x 8.5 TB storage unit. All SAN units are configured as RAID 6 storage systems, with 4 GB local memory and each with a hot-spare disk. The hosts systems have an additional storage server available that contains over 200 different ISO-software images (various operating systems and applications that can be attached during setup of a new virtual system or for installation of additional software during operation). All computing units are connected via 2 x 1Gbit network interfaces for operation of the virtual systems and 2 x 1 Gbit network links for backbone management and backup purposes.

The InIT Blade infrastructure currently hosts over 250 active virtual systems and approx. 8 different templates that are used in various teaching courses, a project- and test-environments of for dedicated research projects. The templates allow the operators to deploy pre-configured Windows- and Linux-Servers within minutes.

A dedicated backup-server is available for raw-backup of running virtual systems or for backup of individual virtual servers, based on user-requests. An agent-based version of the Acronis Backup software allows authorized users to run independent backups of full servers, databases or individual files, not requiring access to the underlaying VMware host systems.

Test-Lab Environment

The InIT Blade Test-Lab consists of 10 x IBM HS21XM and 2 x IBM HS21 blade servers, each equipped with 2 Intel Xeon processors and 32 GB RAM.
They share 2 SAN storage units IBM DS3400, each with 36 x 250 GB storage volume, organized in various LUNs for different exercises and training Labs.

Connectivity and internet access is managed via a BladeCenter chassis and three 6-port 1Gbit Ethernet switches, while the SANs are attached via 4Gbit fiberoptic switches to allow a maximum of flexibilty and configuration options for different lab-tests.
