General recommendations

Your installation may have different requirements and some portfolio sizes may need larger configurations. Feel free to contact the Technical Services Group for more information. Other considerations include:

• Machine names must be uppercase for all machines running Touchstone and Touchstone Re.
• For an in-place upgrade: To retain the historical analysis log files, back up all the folders/files under {Install Directory}:\Program Files\AIR\Work\OutputManagement.
• All model files should be installed on the model share rather than on the local drive for space considerations.
• The recommended ratio is one model share for every 32 compute cores.
• SSAS (SQL Server Analysis Services) must be installed in multi-dimensional mode for Touchstone installations.
• Clients that license APIs must run the head node and the Application Server on separate servers.
• Due to the complexity of the model, Verisk recommends running each Verisk Severe Thunderstorm Model for the United States analysis in Touchstone one at a time.
• Once installation is complete, inspect and review the installation log files on each node for any errors under C:\Program Files\AIR\Logs.
