Review summaries and opinions

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

ROI

Sentiment score
7.0
PowerScale enhances data management efficiency, reducing costs and energy usage while boosting performance, reliability, and operational efficiency for enterprises.
Sentiment score
5.1
Panzura CloudFS enhances network resilience and efficiency, drastically reducing latency and boosting productivity compared to traditional systems.
Despite being more expensive than Huawei, it is stable and most enterprises accept the price due to its stability.
In terms of Dell PowerScale (Isilon) specifically, we have seen a return on investment due to faster performance than our last few storage arrays, and the general usability is a lot better.
The second cluster of Dell PowerScale (Isilon) gives us flexibility for small things like code upgrades, all the way to scenarios where we have lost this data center or data, allowing us to check if data is still intact on the other side.
Previously, we had latency issues with syncing up files between offices. Files were not locked, leading to overwrites which cost us literally hundreds of thousands of dollars in lost time and revenue.
We saw the benefits of Panzura CloudFS immediately because our remote offices were able to share files immediately after the product went live.
Panzura CloudFS saves us a significant amount of time frequently.
 

Customer Service

8.3
Dell PowerScale customer service is praised for responsiveness and knowledge, though some report mixed experiences with first-level support.
Sentiment score
6.8
Panzura CloudFS support is praised for responsiveness and expertise, despite occasional inconsistency, especially in handling urgent issues promptly.
Support online is definitely a ten out of ten.
Dell provides support within four hours, and they always fulfill their promises.
They have managed previous issues well.
The support staff and the number of people they have on staff right now are truly good.
When we have a priority-one issue, we typically receive a call within 20 to 30 minutes.
I would give the support for Panzura CloudFS a ten out of ten because they are responsive and helpful.
 

Scalability Issues

Sentiment score
7.6
Dell PowerScale efficiently scales with large data demands, seamless expansions, and supports diverse applications with on-premise and cloud integration.
Sentiment score
6.8
Panzura CloudFS is praised for its adaptability, scalability, and efficient deployment, supporting seamless expansion and extensive concurrent user access.
We started on PowerScale with around about 300 terabytes and are now two and a half petabytes, still on the same file system.
That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.
Dell PowerScale is highly scalable, as evidenced by the reduced physical hardware and the efficient use of rack space.
Unlimited users can access the system without issues.
From our original entry with Panzura CloudFS, we have added an additional seven sites, and deploying those additional nodes was very seamless and did not take any effort.
The latest version, 8.0.2, has better ease of decommissioning filers and bringing new ones online.
 

Stability Issues

Sentiment score
8.3
Dell PowerScale (Isilon) offers excellent stability with minimal downtime, efficient clustering, and high user ratings for reliability.
Sentiment score
6.1
Panzura CloudFS stability ranges from seven to ten, with notable improvements over time and rare recent issues.
Since we have good protection levels, the data is secured and replicated across the disks.
I assess the stability and reliability of Dell PowerScale (Isilon) as perfect.
I find the product to be resilient and stable. There's no downtime and no crashes.
I would rate it a nine out of ten for stability.
We have never had their system crash on us.
There were times with file lock issues between filers, causing various anomalies, but with their ongoing development, these issues have improved.
 

Room For Improvement

Dell PowerScale struggles with high costs, complex updates, limited improvements, and lacks cloud and multi-tenant capabilities.
Users want better remote performance, compatibility, lower costs, and reliance reduction on local tech for improved service stability.
Hardware failures under warranty should be addressed within the promised timeline.
I would want to see more AI features with Dell PowerScale (Isilon).
If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened.
When something goes wrong somewhere, there should be a little bit better alerting with issues before they become a big problem.
The GIS data formats, such as a geo database, have been found better kept outside of Panzura CloudFS.
It would have been nice if they had offered them in increments, of 5, 10, 15, or 20 terabytes than having to get a whole chunk of 25 terabytes again for licensing purposes, which is a little costly.
 

Setup Cost

Dell PowerScale is costly but offers fair pricing and scalability, appealing to enterprises with extensive data requirements.
Panzura CloudFS is costly yet transparent, offering limited tiered licensing and occasional new hardware needs at manageable prices.
It's quite expensive for the amount of storage we have.
My experience with pricing, setup costs, and licensing for Dell PowerScale (Isilon) shows it's a premium platform, so it's a big amount of money.
The pricing is excellent.
It did require us to purchase new hardware, however, that was not overly expensive.
They should consider more attractive pricing for companies of our size.
Overall, it is quite costly compared to NetApp and similar solutions.
 

Valuable Features

Dell PowerScale excels in management, scalability, and performance, offering flexibility, resilience, and cost-effective storage with advanced monitoring.
Panzura CloudFS offers robust collaboration, file management, data protection, and strong performance with excellent support and enterprise application.
Dell PowerScale offers high scalability and stability as well, making it a valuable solution for enterprises.
In our AI initiatives, Dell PowerScale (Isilon) plays a significant role in data analysis, data fusion; principally, it is involved in data analysis, data extraction, and statistical analysis.
Single files are limited to four terabytes in our configuration, however, the system can support up to 16 terabytes, so we can scale based on that too.
It is very reliable and very quick.
It helps us increase network resilience. We have a primary object library stored in the cloud and have Panzura Mirroring which allows us to place data in a secondary cloud for added resiliency.
There is no degradation of speed because these filers have cached the data, and they are constantly swapping metadata and updating with each other, which is a very attractive method of getting us to use these applications.

Featured Reviews

Scott Taylor - PeerSpot reviewer
Manages large data sets efficiently with hybrid cloud integration
My organization is quite large, with about 30,000 employees. The growth has been substantial in areas such as radiology and genomics. One of the best features we've utilized recently is offload to cloud pools due to capacity constraints on-premise. We didn't want to expand Dell PowerScale (Isilon) straight away, so we utilized cloud pools to offload some data to Azure. That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.
Roger Clark - PeerSpot reviewer
Handles file locks effectively enabling seamless remote collaboration in global teams
It has not reduced the data storage cost. We have been trying to come up with a plan internally to archive project data at a certain time frame. However, our data continues to grow, so at the point of 25 terabytes, we had to buy another 25 terabytes license to exceed that threshold. It would have been nice if they had offered them in increments, of 5, 10, 15, or 20 terabytes than having to get a whole chunk of 25 terabytes again for licensing purposes, which is a little costly. It would be nice if Panzura offered data in increments instead of 25 terabytes per license. They have done a pretty good job of development from the point of offering new products. Pricing seems to be high for certain things, such as the audit feature of Panzura Data Services. It would be nice to see who deleted that 100 gig of data out there. They should make the pricing plan more attractive for a company of our size. We have almost 700 employees over the southeast from Texas to Florida and up to Tennessee, so we are a pretty big region.
