none
duplicate scenario

    Question

  • Hi,

    I havean infrastructure currently in production this way:

    1.-Balancer hardware.
    2.- 2 IIS Front Servers (aspx)
    3.- 2 SQL BackEnd Servers in cluster.

    The data of servers (IISandSQL) is in NetApp storage.

    My question.

    As I can simulate this virtual scenario to make a test?, we must keep in mind that I do not have the balancer or the storage. There any alternatives to simulate these two software hardware?

    Thanks

  • Can you simulate the environment?  Yes, but only from a functionality standpoint.

    F5 and NetScaler both offer virtual appliance versions for the load balancer.  Everything else can be a VM.

    If you want to simulate hardware performance, you cannot do this (at least not in any way that is built in).  So, you cannot 'simulate' performance.

  • You can, but not without duplicating components of the infrastructure.

    So, the NetApp simulator does not apply, but a ANS product such as Windows Server with iSCSI, or FreeNAS, or OpenFiler might provide the same end results.

    It all depends on the intent.

    We cannot design your test / development environment for you.  For one, we don't fully understand your requirements.

    Can you fully simulate an enterprise deployment with virtual machines?  Yes.  Can you do it exactly like a physical deployment?  No.  Can you substitute components with something different that acts similarly in the topology?  Yes.

    If you are performance testing then you need the actual hardware.  If you are just simulating a topology, they you have to get creative.

  • Hi,

    Both F5 and NetScaler virtual appliance versions offer for the load balancer. --> OK
    As a simulate one NetApp or similar?

    I do not mind the performance, is to develop.

    Thanks for the quick reply.

  • NetApp has a simulator.  You need a business contact and need to be a customer to gat access.

    You can't use it as storage, but you can use it to develop to (with the NetApp API).

  • Thanks for the info.

    I cannot simulate concurrent access from multiple servers to a single location of data?
