Platform details

The CloudMIP platform is currently hosted in the datacenter of our university.

Virtualization From a Virtual Machines point of view, CloudMIP is able to host up to 276 VMs each featuring 1 physical CPU and upto 4GB RAM (stands for Amazon medium instance).

Below is an overview of the CloudMIP platform. CloudMIP architecture overview.


The CloudMIP nodes. The platform consists of the following items:

  • a front-node,
  • a NFS server,
  • 32 nodes (blades) dispatched within two DELL M1000e chassis,
  • 1 additional hypervisor Dell R630 (20 cores, 128GB RAM).

[1] Front-node
The front-node is a Dell R710 featuring 8 cores XEON@2.8GHz, 48GB DDR3 memory and 6 x 146GB 15ktpm SAS drives in a RAID6 setup.
This server is running a CentOS 7.2 Linux distribution.

[2] NFS
Our new NFS server (bought by neOCampus and the EU Fabspace 2.0 project) is a powerfull Dell R730xD featuring 16 x 4TB NL-SAS in a RAID6 configuration. The XFS filesystem gives access to more than 50TB of useful storage space featuring > 2GB/s throughput.

  • 16 cores Xeon E5-2620 v4 @ 2.10GHz,
  • 32GB DDR4 2100MHz,
  • Fedora Core 24 distribution.

[3] Nodes
Each Dell M1000e chassis features an embedded KVM, two redundant CMCs, 9 fans, 6 redundant power supplies and two Dell PowerConnect M6220 Gigabit Ethernet switches.

Each of the 32 nodes filling the chassis are Dell M610 blades. Each one exhibits the following features:

  • two XEON E5620 (Westmere) @ 2.4Ghz (i.e. 8 cores),
  • 48GB DDR3 RAM,
  • two gigabit Ethernet links,
  • two SAS 15ktpm 146GB hard drives,
  • CentOS 7.2

One additional hypervisor Dell R630 bought by CNRS Big Data Challenge Mastodons :

  • 20 cores Xeon E5-2640 v4 @ 2.40GHz,
  • 128GB DDR4 2400MHz,
  • CentOS 7.2

With such configuration, the whole system features 276 physical cores and 1.6TB RAM. On its side, with drives in a RAID0 configuration, the achieved I/O throughput is over than 300MB/s.


To take advantage of the multiple embedded Gigabit Ethernet interfaces of our servers, we aggregated (i.e trunk) all of them into single devices. Then, vlans segmentation is applied.
