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.

Stability-wise, a device that has been up and running for years
The solution is useful for machine learning and scientific applications, including computer simulations The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Dell PowerScale includes a wealth of features that are important from a security and recovery perspective."
"Dell PowerScale's performance is good."
"The product's scalability feature is super easy to use."
"It assists with eliminating storage silos because it provides SMB and NFS protocols. PowerScale has also helped free up our employee's time to focus on other business priorities."
"The tool's most valuable features are high density and scalability."
"Its most valuable feature is the DR capabilities replication."
"It has allowed us to have more consistent quality controls. It has also allowed us to expand the number of servers in clients processing and accessing data, allowing us to get a lot bigger projects out the door."
"The solution provides massive performance, scalability, efficiency, and ease of management."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
 

Cons

"The tool's support team and the way the cases are handled by the product's technical support team are both areas of concern where improvements are required."
"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."
"Its configuration needs to be more straightforward."
"PowerScale is not suitable for virtual environments."
"It would be good to have synchronized mirroring between two clusters without using a third-party program."
"Dell PowerScale (Isilon) could improve the load distribution capability. For example, in some cases, the system load is not distributed automatically on all the nodes but is concentrated only on one. You have a peak request on only one node and the others don't do anything."
"Dell PowerScale's deployment is not easy."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
 

Pricing and Cost Advice

"It is a really expensive solution."
"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."
"The price of Dell PowerScale (Isilon) is reasonable."
"It is an expensive solution."
"We use the TNA approach which is a great opportunity for us to better manage the licenses based on how much consumption is available for the different customers so we can use that approach and scalability."
"Dell PowerScale (Isilon) is an expensive solution."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
