Parallels H-Sphere Details

Latest Distribution


Information about H-Sphere installation and usability is provided below.

Operating Requirements

The H-Sphere management node can be installed on a single server, but multiple servers are recommended. H-Sphere can be installed on a Pentium III, 500MHz CPU with 512MB of RAM, but this will support only a few accounts. A 1000MHz CPU and 1GM of RAM is recommended.

In addition to the hardware, the following is required:

  • Environment — Full control of DNS, mail, web, and other hosting servers is required during installation and testing.

  • IP Address — H-Sphere can be installed only on public IPs.

  • Domain Registration — To provide domain registration services with OpenSRS, you will need a Full Access Account. Contact OpenSRS technical support and notify them that you are using H-Sphere to get requirements for the test waived.

  • Payment Gateways — To accept credit cards in real-time, you will need an account and gateway access through one of the supported payment gateways.

Please be aware of H-Sphere Services and Supported OS’s EOL dates.

Application Server Requirements

H-Sphere is aware of all other servers in the hosting platform. The Control Panel server manages all new machines, users, domains, and events. When a user enters the system and creates a new account, the control panel server dispatches commands to the DNS, mail, and web servers to configure the services and writes information about the user to the database.

An H-Sphere configuration includes the following servers:

Server Type
Operating Systems
Supported Software
1 Control Panel Linux or FreeBSD * System Database: PgSQL 7.x, Java 1.5+ and Tomcat 6.0.x You can have only one CP server

10 VPS RedHat Enterprise Linux 5

(*) Servers 1 through 5 can be combined on one or more servers. The Control Panel server is required; other servers can be installed later.

You need more than one server if you are going to offer one of the following:

  1. Windows hosting: Windows Web, MS SQL, and Windows RealMedia servers are set up separately on Windows 2003/2008 platform and can also be combined in any possible way.
  2. PgSQL database hosting: PgSQL server for user database hosting can’t share the box with the control panel server, because the latter runs with system PgSQL database.
