Deployment scenarios and requirements

by zadmin last modified 2007-12-21 18:16

This section describes two possible deployment scenarios together with their requirements.

First scenario: all GRID services in one host.

For running GRID Seed in one host, the following are the minimal virtual machine requirements. Please beware that everything will be very slow.

Central Service:

DNS 1CPU 256 MB

VOMS 1CPU 256 MB

BDII 1CPU 256 MB

LFC 1CPU 256 MB

WMS 1CPU 256 MB

Site:

CE-1 1CPU 256 MB

SE-1 1CPU 256 MB

CE-1WN1 1CPU 256 MB

User Interface:

UI 1CPU 256 MB

For a total of 9 CPUs and 2.25 GB of RAM.

Alternative deployment scenario:

As an alternative you may use a different hosting machine for each VM; each host should have a minimum of 512 MB of RAM but preferably 1 GB to avoid swapping problems.

In each host you must have:

  1. A local user called gridseed.

  2. VMWARE server installed and configured for bridging network
