dCache Hands-on Taipei

Prerequisites

We would like to ask every participant to bring a notebook that has some kind of ssh client installed. Please check on your machine.

You need to login to your virtual machines (VMs). You have two VMs, one server and one client:

  • <user number>_ws_server.grid.sinica.edu.tw
  • <user number>_ws_client.grid.sinica.edu.tw

You will have to use two consoles, one for the server and one for the client. Use your ssh-client to connect to the machines using the following commands. Client:

      ssh dcache-user@<user number>_ws_client.grid.sinica.edu.tw -A -X

Server:

      ssh dcache-user@<user number>_ws_server.grid.sinica.edu.tw -A -X

Content of the hands-on

In this hands-on we will cover the following topics

  • Installation of dCache server
  • Interaction with dCache
  • Certificates and dCache
  • Hardware Lifecycle (adding storage, migrating)
  • Interfacing with Tertiary Storage

Installation of dCache server

I this part we install dCache and at the end have a running dCache that can be mounted locally as well as on your client.

  1. Get dcache server rpm from our website:
        wget http://www.dcache.org/downloads/1.9/repo/2.5/dcache-2.5.0-1.noarch.rpm
    
  1. Install the rpm on your server machine:
        
    

Interaction with dCache

In this section we will look at the different ways of interacting with dCache to make use of its functionality.

Certificates and dCache

This part will have a look at the security mechanisms that are used within the Grid.

Hardware Lifecycle (adding storage, migrating)

Here you will see how to maintain a dCache that is in production. This part will include adding storage and migrating data.

Interfacing with Tertiary Storage

Finally we will look at how dCache can be used to access archive media (tape archives)
