Data Center Tour - Hardware Configuration

Server Hardware Configuration

In our data center in Kiel, Germany we have more than 500 servers. In order to provide the leading performance level we are known for using the following technologies on our reseller cloud hosting platform:

Cluster (cloud) technologies:

LVS – Linux Virtual Server is a highly scalable and highly available server built on a cluster of real servers with a load balancer running on the Linux operating system.
Heartbeat – Provides a high availability (clustering) solution for Linux which promotes reliability, availability, and serviceability (RAS) for the reseller cloud hosting platform.
VRRP – Virtual Router Redundancy Protocol.
Ultra Monkey – High Availability and Load Balancing Solution for LinuxXEN – Powerful hypervisor – industry standard for virtualization, which offers a powerful, efficient and secure feature set for virtualization of x86, x86_64, IA64, ARM and other CPU architectures.
VMware – virtualization platform that dramatically improves the efficiency and availability of resources and applications.

Server technologies:

The following operating systems are used in the formation of the core of our hosting infrastructure:
Debian, RedHat, CentOS, SuSE, Slackware – We use different Linux distributions with their best features where they best suit our need for an optimal performance.
Microsoft Windows Server 2003/2008 – The most advanced server based on the Microsoft operating system used by thousands of developers around the globe.

File system technologies:

RAID1, RAID6 – Redundant Array of Inexpensive/Independent Disks that allows achieving high levels of storage reliability, extended capacity and performance.
LVM2 – An innovative user space toolset that provides logical volume management facilities on the Linux reseller servers.
NFS – Network File System is a network file system protocol allowing a client computer or a server to access files over a network in a manner similar to local storage.
iSCSI – Internet Small Computer System Interface, an Internet Protocol (IP)-based storage networking standard for linking data storage facilities.
XFS – a high-performance journaling file system particularly proficient at handling large files and offering smooth data transfers.
DRBD – Block device designed as a building block to form high availability (HA) clusters.
GFS – Red Hat Global File System is an open source cluster file system for enterprise deployments allowing the management of cluster servers at one single instance.
OCFS – Oracle Cluster File System presents a consistent file system image across servers in a cluster.
CLVMD – A daemon that distributes LVM metadata updates around a cluster.
LUSTRE – A Network Clustering File System designed for high performance and scalability.
GLUSTERFS – A cluster file system capable of scaling to several petabytes, based on a stack of available user space design.

Database technologies:

MySQL, MySQL Cluster, MySQL Replication – The MySQL Enterprise Server software is the most reliable, secure and up-to-date version of MySQL for cost-effectively delivering E-commerce, Online Transaction Processing (OLTP), and multi-terabyte data warehousing applications. MySQL Cluster is the industry’s only true real-time database that combines the flexibility of a high availability relational database with the low Total Cost of Ownership (TCO) of open source.

Postgres & Postgres triggers – PostgreSQL is a powerful open-source object-relational database system that boasts sophisticated features such as Multi-Version Concurrency Control (MVCC), point-in-time recovery, table spaces, asynchronous replication, nested transactions (save points), online/hot backups, a sophisticated query planner/optimizer and write-ahead logging for fault tolerance.

Web server technologies:

Apache2 – The Apache HTTP Server Project is a robust, commercial-grade, full of features, open source code implementation of an HTTP (web) server. It is also an effort in developing and maintaining an open-source HTTP server for the modern operating systems.

thttpd – Simple, small, fast, and secure HTTP server. It doesn’t have a lot of special features, but it suffices for most uses of the web, it’s about as fast as the best full-featured servers (Apache, NCSA Netscape), and it has one extremely useful feature (URL-traffic-based throttling).

MS IIS – Flexible, secure and easy-to-manage web server for hosting anything on the web. From media streaming to web application hosting IIS’s scalable and open architecture is ready to handle the most demanding tasks, reseller cloud hosting services and others. The server parameters are as follows: CPU Processor: Intel Core 2 Quad, RAM memory: 8 GB, Hard Drive: 4×900 GB SATA II Retail, operating system: Debian Linux.

These technologies support our free reseller hosting program, so anyone can become a reseller within minutes and with no initial investment. The reseller cloud hosting platform enables you to offer the whole range of hosting services with great quality.
