Here is the email message that I sent to NCBI: At this time the Standalone WWW Blast server is only available on UNIX web servers. We don't have a UNIX server in-house and would like to buy one to use for the Standalone WWW Blast server. What is the minimum requirements (memories, hardware, software) to deploy the software? What kind of UNIX machine (HP or Sun) do I need? What kind of web server (weblogic or websphere)? I haven't received a response from them yet and I need the answer soon. So does anyone know the answer? Did anyone try to put the software on a LINUX server? If so, were there any difficulties versus on a Sun Unix server?
