TBDThe [http: PJU/DVO/www.stoney-cloud.org/ stoney cloud] builds upon various standard open source components and can be run on commodity hardware. The final Multi-Node Setup consists of the following components:* One [[Primary-Master-Node]] with an OpenLDAP Directory Server for the storage of the stoney cloud user and service related data with the web based management [[VM-Manager]] interface and the Linux kernel based virtualization technology.* One [[Secondary-Master-Node]] with the Linux kernel based virtualization technology.* Two [[Storage-Node | Storage-Nodes]] configured as a replicated and distributed data storage service based on [http://www.gluster.org/ GlusterFS].The components communicate with each other over a standard Ethernet based IPv4 network. == Prerequisites ==The following items and conditions are required to be able to install and configure a stoney cloud environment:* A dedicated server which fulfils the following requirements: ** 64-Bit Intel with VT-Technologie (AMD is not tested at the moment, but it should work).** 8 Gigabyte Memory (more is better).** 147 Gigabyte up to 2 Terabyte disks (for the first RAID set, the 2 Terabyte restriction applies).*** Two 147 Gigabyte Disks, configured as RAID1, are more than enough for the [http://www.gentoo.org/ Gentoo Linux] operating system.*** For the mass storage (where the virtual machines are stored) we recommend a second RAID-Set configured as [http://en.wikipedia.org/wiki/RAID_6#RAID_6 RAID6]-Set with battery backup.** One or more physical Ethernet Interfaces, which support the same bandwidth (for example 1 Gigabit/s).* Two Gigabit layer-2 switches supporting [http://en.wikipedia.org/wiki/IEEE_802.3ad IEEE 802.3ad] (dynamic link aggregation), [http://en.wikipedia.org/wiki/IEEE_802.1Q IEEE 802.1Q] (VLAN tagging) and stacking (optional, but recommended).* Experience with Linux environments especially with [http://www.gentoo.org Gentoo Linux].* Good experience with IP networking, because the Switches need to be configured manually (dynamic link aggregation and VLAN tagging). == Limitations ==During the installation of the [http://www.gentoo.org/ Gentoo Linux] operating system, the first two physical Ethernet Interfaces are automatically configured as a logical interface (bond0) and the four tagged VLANs are set up. If more than two physical Ethernet Interfaces are to be included in to the logical interface (bond0) or the physical Ethernet Interfaces have different bandwidths (for example 1 Gigabit/s and 10 Gigabit/s), the final logical interface (bond0) needs to be configured manually after the installation of the [http://www.gentoo.org/ Gentoo Linux] operating system.Only the first two [http://www.gluster.org/ GlusterFS] [[Storage-Node | Storage-Nodes]] are set up automatically. More [[Storage-Node | Storage-Nodes]] need to be integrated manually. == Installation ==
