Network Configuration and Data Storage

  • The VM will be operating in NAT mode. This means that the host machine runs a process that emulates a router with a NAT enabled. Most NATs run in the address space of 192.168.xxx.xxx. Your VMware installation will choose the 192.168.xxx part of this, and the DHCP server inside that NAT will assign the last three digits at will to individual VMs. Since this is a NAT, these IP addresses are not accessible from the outside without special configuration. The NAT emulator is presently somewhat processor-hungry. We recommend using it in spite of this defect because shared filesystems with the host are much faster in NAT mode than in bridged mode.
Line: 41 to 41
 
  • This interest in shared filesystems (such as hgfs, NFS and xrootd) arises from a desire to be able to store both datasets and ATLAS software installations once and give access to both the host and several VMs as necessary, with the most performant access possible.

Installation

<
  1. Download the file located at http://www-hep.uta.edu/~stradlin/Tier3VM/Tier3.1.tbz ( Tier3.1.tbz). You can also download Atlas.tbz Atkas.tbz if you intend to install Athena (see below).
  2. Untar the virtual machine (tar -xjf Tier3.1.tbz) and place it somewhere on your boot volume.

  1. In the VM Settings (varies for different platforms), set a Shared Folder to point to your /DataShare directory, if it has not happened automatically.

Athena Installation
Two methods can be used - both take substantial download time.
Changed:

  • For Athena 14.2.20, download Atlas.tgz, and untar it - tar xzf Atlas.tgz. When untarred, copy it into your Tier3.1 VM to replace the existing Atlas.vmdk file. You can also download the AtlasOld.tgz package, giving you Athena 13.0.40 and 14.2.0.
