Description
The INFN Tier1 at CNAF is the first level Italian High Energy Physics
computing center that shares resources to the scientific community using
the grid infrastructure. The Tier1 is composed of a very complex
infrastructure divided into different parts: the hardware layer, the
storage services, the computing resources (i.e. worker nodes adopted for
analysis and other activities) and finally the interconnection layer
used for data transfers between different Tiers over the grid. Any
update of the different parts of this infrastructure, in particular a
software update or a change in the services software code, as the
activity of adding new hardware, should be carefully tested and debugged
before switching to production. For this reason a test bed facility has
beed gradually built in order to reproduce the behaviour of the
different layers of the Tier1 in a smaller but meaningful scale. Using
this test bed system it is possible to perform extensive testing of both
the software and hardware layers and certify them before the use at the
Tier1.
