Question

Coldfusion share on NAS

  • May 9, 2006

Hi I'm doing my due diligence for our network team. We have three stand alone Coldfusion servers being load balanced through a Cisco CSS. Those servers are all accessing Coldfusion scripts through one shared virtually mounted drive on our NAS (NS600 model from EMC). That is, we installed the run-time Coldfusion application on the the local server c drive but access our custom tags, components and scripts on the share. It is slowwwww on the preprod....but worse, it's intermittent with performance very up and down (but mostly down).

So we're taking systematic steps to solve this problem. The network guys would like to know: Is Coldfusion compatible with this architecture? Can it support a shared drive using NAS technology and still function correctly without hangups or issues?

Simple question, but difficult to find someone who actually knows the answer. Any help in pointing me in the right direction, even to get a very positive - "of course Coldfusion can work this way" so I can close this line of questioning - would be greatly appreciated.

Cheers,

Matt

    Beyond knowing that's basically how we have our setup configured as
    well, I'm not sure how much further assistance I could be on the
    performance problems since at that point it would likely be entirely
    network and/or hardware oriented. I know, for example, our entire
    network is gigabit, we have all fiber channel drives, and we have a
    dedicated NIC for communication between the web servers and the EMC.
    Our network guys set this all up so as far as what else is involved
    beyond that I wouldn't really know.

    If you have any other specific questions that I might be able to help
    troubleshoot either myself or by asking our network guys, please feel
    free to let me know.

    Matt, I can't ask for anything more than that. My main goal was to establish that it wasn't a Coldfusion specific problem which you have validated.

    Thanks again.

    Matt, brilliant. Here's what my network guys said:

    - We are using CIFS.
    - The technical CF user is part of the domain and is running the CF services.
    - The NAS is part of the domain.

    Do you do consulting as I think a few hours on the phone could move this forward? It's not easy finding expertise on CF infrastructure in Switzerland.

    Cheers,

    Matt

    ColdFusion can absolutely work this way. We run our apps this way with
    no problems on an EMC. Specifically how are you accessing your EMC
    shares? Do you hit the EMC as a CIFS/NFS share or do you use iSCSI?
    We're using CIFS and haven't had any performance issues. The other
    thing that can slow things down is authentication. How are you
    authenticating to the EMC? What user is CF running as on your web
    servers? Is the user CF is running as a domain service account or
    something similar? Is the EMC on the same domain, and if not, do you
    have a trust set up so authentication doesn't happen on every request?

    Lots of questions I know but in order to troubleshoot performance issues
    these are the sorts of things to consider. The short answer to your
    question is that this will absolutely work, and we've had excellent
    performance with this setup.
