Dell PowerScale support is responsive and knowledgeable, but users report delays with first-level assistance and varying engineer efficiency.
Sentiment score
8.0
Nasuni's customer service is praised for responsiveness and professionalism, efficiently solving issues with reliable and knowledgeable support.
Support online is definitely a ten out of ten.

When we face issues, we raise a ticket through the valid portal, and they respond immediately and assign a local engineer to coordinate the support process.
Senior System Engineer at a financial services firm with 10,001+ employees
On a scale of one to ten, I would rate Dell's technical support a ten.

Scalability Issues

Sentiment score
6.8
Dell PowerScale offers seamless scalability, enabling growth and efficient data management with flexible on-premises and cloud integration.
Sentiment score
6.9
Nasuni offers scalable, user-friendly data storage, efficiently meeting diverse organizational needs and supporting physical or virtual deployments.
We started on PowerScale with around about 300 terabytes and are now two and a half petabytes, still on the same file system.
Storage Architect at a educational organization with 10,001+ employees
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.
Senior Infrastructure Specialist at a healthcare company with 10,001+ employees
As an unstructured data storage solution, writing into it and accessing it from the other nodes is highly scalable with no issues.
Senior Technical Engineer at a tech vendor with 10,001+ employees
I rated the scalability as seven because even though the solution can scale, load balancing must be done manually, as it's not automated.

Room For Improvement

Dell PowerScale requires better pricing, intuitive interface, easier deployment, enhanced performance, security improvements, and advanced cloud and AI integration.
Nasuni struggles with cloud integration, performance, and user experience, needing improvements in data retention, security, and analytics.
Firmware or software updates become effortless with Pure, but with Dell PowerScale (Isilon), we must evaluate or conduct trial runs to ensure that these operations will not harm our customer's system; their software is not adequate.
Senior Ai Architect at Logicalis
It should be made more user-friendly in the sense that if I manage it, I should be able to deploy it without having to have a lot of interaction from support.
Manager, Information Technology at a transportation company with 11-50 employees
Regarding Dell PowerScale's AI capabilities, I believe its governance and security are more important for financial or government sectors, so governance and security will require additional upgrades and hardening.
Storage engineer at a financial services firm with 10,001+ employees
I would improve Nasuni by addressing the performance issues we sometimes face on the base file share, which must be fixed.
Consultant at a tech vendor with 10,001+ employees
I suggest Nasuni improve their syslog forwarders to support TCP protocol, as it's more secure than UDP, which is plain text and not protected at all.
Infrastructure Architect at a energy/utilities company with 10,001+ employees
The purging time is very slow.
Cloud Architect at a media company with 1,001-5,000 employees
 

Setup Cost

Dell PowerScale offers high pricing but justifiable value for enterprise users due to features, scalability, and flexible licensing.
Nasuni offers competitive pricing with flexible cloud compatibility, licensing per terabyte, and cost-effective enterprise solutions.
It's quite expensive for the amount of storage we have.
Senior Infrastructure Specialist at a healthcare company with 10,001+ employees
Cheaper nodes will cost less, while higher performance nodes will be pricier.
Storage Platform Engineer at Expedia Group
Costs align well with what it delivers, making it a fair price for a powerful tool that meets all our needs.

Featured Reviews

Santosh Bharadwaj Rangavajjula - PeerSpot reviewer
Product Manager at a manufacturing company with 10,001+ employees
File sharing has supported collaboration and disaster recovery but security support still needs work
Dell PowerScale can improve specifically for AI workloads, particularly on the MCPs. I would add that we have not seen an official MCP from Dell PowerScale and are relying on open source. It would be valuable to have an MCP server that we can set up directly with them. Regarding Dell PowerScale's AI capabilities, I think its governance and security could be better. We have Superna that we buy along with Dell PowerScale, but we are seeing very big problems with integrating it. Superna is primarily for the security use case, as we want to prevent cybersecurity attacks and ransomware attacks. If Dell is providing this as a supplementary feature, it should provide better support. Regarding Dell PowerScale's AI capabilities, I do not see much accuracy and reliability of output. This is actually a security problem because Dell does not provide official MCP servers while most other vendors are providing it. This forces us to rely on open source, which is not secure. Dell PowerScale plays a role in my organization's AI initiatives as we want to use the Metadata IQ functionality from Dell PowerScale; however, there is not enough support and extensive documentation for us to be able to do this.

Unified cloud file storage has simplified global data management and reduced operational overhead
From an admin perspective, Nasuni has various valuable features. The GUI is very good, upgrading is very easy, and DFS is very easily manageable. Compared with other products, the snapshot feature is beneficial because it creates a snapshot every five minutes, allowing me to provide restores very easily to customers. Data protection is enhanced by the fact that Nasuni uses S3 technology to create snapshots every five minutes and enables versioning, so the snapshot is created and I can utilize that snapshot for disaster recovery or restore purposes. I assess the value of global file locking and caching for reducing latency as good, giving it a five out of five.
