    Hi All,

    We have evaulated PBA for our needs and it looks like the product for us (Just awaiting some pricing which seems to take forever :( ). However, I have been asked to present a design so that we can evaluate our hardware requirements for PBA. My questions are the following:

    1: Can the Database component be seperated from the software components (IE Hosted on another server)?. How involved would this be to setup? If this isn't possible, how do people normally make this highly available?

    2: Can the various components of the system be seperated to run on different systems? For security, I am planning to seperate the pcc and have it hosted on an internal system.

    3: Are high availability setups available with PBA Enterprise? With the trial of PBA standard there doesn't appear to be any of these features.

    OK I have read the Advanced Configuration Manual for PBA and question 1 & 3 above are answered. However, with question 2 in regard to a PBA cluster, does anyone know if the frontend node/s can be further configured to allow certain applications (EG only the cp, not anything else)?

    You may restrict access to PCC and RCC in /etc/httpd/conf/hspc_frontend.conf by adding:

    <Location /hspc/pcc>
    Order deny,allow
    deny from all
    allow from 192.168.0.1 ##replace "192.168.0.1" with internal IP range
    </Location>

    <Location /hspc/rcc>
    Order deny,allow
    deny from all
    allow from 192.168.0.1 ##replace "192.168.0.1" with internal IP range
    </Location>

    Excellent thanks for this...

    Now the document examples show only one frontend server with multiple backend servers. Can you setup/configure more than one frontend server in the cluster?

    Thanks once again Victor!

    Sorry just one more question. Going off the link you provided, the frontend server is just a simple base set of files that can easily be copied across to multiple servers. Is that correct?

    Kaylior, have you checked out H-Sphere? H-Sphere is cheaper and supports the features you are looking for (also from Parallels)

    1,2- Splitting things: H-Sphere maintains logical servers inside physical servers, you can shape it any way you like. You can separate mail, mysql, dns, web etc.
    http://www.psoft.net/HSdocumentation/admin/logical_servers.html

    3- H-Sphere supports load balancing natively
    http://www.psoft.net/HSdocumentation/sysadmin/understanding_load_balancing.html

    * You can use H-Sphere completely firewalled with NAT setup also.
    http://www.psoft.net/HSdocumentation/sysadmin/nat.html

    As well as other features, h-sphere licenses include usage of sitestudio, vps, dedicated server management facilities etc. You are welcome to H-Sphere forums to ask more questions :) http://forum.psoft.net/

    Thanks,
    Evren

    I think it is worrisome that the prices are sent in secret to customers. You wont know if your competitor is paying half of what you are paying. H-Sphere pricing is publicly available, Parallels should do the same for other automation prices.
    H-Sphere pricing -> http://www.psoft.net/price_list.html
