The product is still really somewhat new to us, so the people doing the installations are still gaining experience. It will take some more time for us to get our confidence with the product to truly be at the expert level. But so far we have not faced any major challenges. We have been supported by the OEM itself. So we do not find any major complexity with installing it. If we did, we have full support.  

So we need more time to get to the expert level. After we have done multiple implementations and supported them over time, we will have that extra level of knowledge from working with the product in multiple environments with varied architectures. We can not get this just from testing and use in our own environment alone.  

In our cases with current clients, it has taken extra time to implement and deploy because of client limitations. We have to take some time in the stage of planning with the clients and going through the process correctly so they divulge what they really need and we know how to implement the solution correctly to satisfy that. Implementation is not so simple as I go there and install it. We will have to work with the migration also and do proper planning to achieve the minimum downtime. A lot of the length of time needed for deployment is getting the information we need from the customer. If the process with the client were more straightforward and they knew already what they had to supply to us, the deployment will take much less time instead of spending a lot of time in discovery. The implementation has been taking almost a quarter (three months), because of the complexity.  

First, you should know the concept of data flow in your product so that setup is not a big deal. Then, you should understand the structure of ScaleIO; that is useful for installation.
