Operates seamlessly and minimizes downtime while meeting enterprise file share demands
The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed. These features benefit my company by providing less downtime and less overhead. While I have not calculated an exact number regarding the reduction in downtime, we have always been using the product, so we have no baseline to compare it to. However, it is a very good product. Dell PowerScale (Isilon) scales very well with the growing needs of my company.

Vmware Windows Senior Engineer at a manufacturing company with 10,001+ employees
Resilience has supported proactive management and secured audit readiness across multiple sites
The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place. I see Dell PowerStore playing a bigger role in the future because we are starting to use it more, and that is pushing it. The biggest return on investment for me when using Dell PowerStore is scalability. Scalability is key. I can amplify that scalability is the biggest return on investment because we have redundancy between two sites; if something goes down, we have to manage it, but we want to do it proactively.
