Helps reduce data silos, improves performance, and flexibility
Our customers have seen improvement in performance, space, and flexibility for growth and management of data protection through snapshots and other systems. The AI models are something we are looking forward to trying but are not there yet. The algorithms are specific to each company and their industry. One of the most important things is the data localization. Many scenarios require the project data traffic to be close to where it is generated and read. A lot of interaction is between users and systems. So data localization is one of the most important things in terms of using the data algorithm. We don't need to manage our PowerScale and run its storage from any location yet but it is something that is coming for sure because several customers have centralized data in main data centers. But in different locations across the globe. So this is going to be a topic. I think that through the different functionalities that the Dell platform can grant, it will be a great player. When it comes to the flexibility for supporting various data workloads while protecting them, the combination of PowerScale and PPDM and all the other components of the data protection solution right now is key. So the automatic integration between the products is one of the killer features of the solution itself. PowerScale helped us to reduce data silos. This has simplified the management of large data environments in terms of scalability and management instead of having a different solution for the right reports to see how the data evolves and how to better manage them. PowerScale can do that in combination with the other components of the ecosystem. In terms of risk reduction, We need to mention the data management and the recovery part, So of course, the integration with the data domain is key. The fact that we can rely on these functions, and the fact that we also manage different customers, and possess the recovery plans and tests that can prove the solution is working.

Uninterrupted upgrades accelerate performance with good support
I would rate the solution eight out of ten. It should be noted that in Pakistan, some parts are not readily available, and we need to import them from Singapore or other countries. We encountered an issue with a customer where the midplane failed and was not available. We had to wait for several days for a replacement, even in a 24/7 support case. Additionally, we faced motherboard failures in the customer's environment, encountering two motherboard failures simultaneously. We obtained one motherboard immediately, yet had to wait ten days for another. These issues should have been resolved promptly given the 24/7 support level.

Measuring Up: EMC XtremIO and HP 3PAR
Leading up to EMC World 2015, IT Central Station asked how I would compare EMC XtremIO and HP 3PAR.

To that end, I've written a…
