Eric Burgueño - PeerSpot reviewer
Simplified data management, tremendously reducing our users’ cognitive overhead
The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB. You can either access a file because it can be access by anyone in the organization, or you cannot at all. There is no in-between. HTTP is not considered a first-class data access protocol, so the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply. However, with the recent introduction of S3 starting from OneFS 9, I believe the necessary plumbing is already there for HTTPS to also be elevated to a first-class protocol in the future because both protocols sit behind a web server under the hood. It does not sound like it would be too complicated to implement, but it would be a valuable feature and it is currently missing.
Andy Knauf - PeerSpot reviewer
Reliable file management and disaster recovery with minimal overwrites
For me, it is the stability aspect. It is a lot more stable now than it ever has been, but just keeping that stability is important. Previously, a new update would come out, and there might be something wrong with it, or it may not sync up as well as it should, or it may cause something to lose access to the server. We have had some problems in the past, but in the last couple of years, we have not had any issues like we had early on. There could be a slightly better dashboard or a better pane of glass. When something goes wrong somewhere, there should be a little bit better alerting with issues before they become a big problem.

Quotes from Members

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

Pros

"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"The flexibility and the user-friendly interface are the most valuable features."
"The solution's most valuable features are scalability and flexibility."
"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."
"Features like ransomware protection, file lock retention, and third-party integrations (e.g., Superna for ransomware protection) are significant benefits."
"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"The most valuable feature of Dell PowerScale is its scalability."
"The core function of Panzura CloudFS, with its synchronizing of files across multiple servers, provides us with a much more efficient workflow for our production staff."
"What I appreciate most about Panzura CloudFS is that it really solves the problem we had when we moved all our server workloads to Azure, reducing our on-prem data center footprint sizably. We don't have to maintain a huge on-prem storage array, which is nice. It just works, and we haven't had any issues this whole time."
"Panzura is a hundred percent better than what we had before."
"Its most valuable features are the collaboration, the file snapshots, and the data protection the solution provides."
"What I appreciate most about Panzura CloudFS is that it really solves the problem we had when we moved all our server workloads to Azure, reducing our on-prem data center footprint sizably."
"It is a very solid product. We keep all of our older files on their system. It is easy to restore if a file gets deleted. We have good disaster recovery. It is very reliable and very quick, and we do not have files that get overwritten because it locks the file."
"The assistance of support has been excellent."
"Primarily, it is the way Panzura CloudFS handles the file locks and the way these filers, along with the authoritative copy of all our data, which is about 27 terabytes located in an AWS bucket in the cloud, operate."
 

Cons

"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."
"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."
"PowerScale is not suitable for virtual environments."
"The price always has room for improvement."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"The UID mapping and how to configure mapping-related things is a struggle."
"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."
"Master Snapshot feature is the only exceptional feature, but the rest of the features are similar to other storage solutions."
"It would be nice if Panzura offered data in increments instead of 25 terabytes per license."
"There could be a slightly better dashboard or a better pane of glass. When something goes wrong somewhere, there should be a little bit better alerting with issues before they become a big problem."
"There are a few file types that do not work well with Panzura CloudFS."
"One area for improvement regarding Panzura CloudFS is moving away from on-prem or local Active Directory. We're exploring a transition to Azure AD or Entra ID, aiming to keep the product functional without heavy reliance on the local Active Directory."
"Previously, a new update would come out, and there might be something wrong with it, or it may not sync up as well as it should, or it may cause something to lose access to the server."
"There are a few file types that do not work well with Panzura CloudFS. Specifically, the GIS data formats, such as a geo database, have been found better kept outside of Panzura CloudFS."
"One area for improvement regarding Panzura CloudFS is moving away from on-prem or local Active Directory. We're exploring a transition to Azure AD or Entra ID, aiming to keep the product functional without heavy reliance on the local Active Directory."
 

Pricing and Cost Advice

"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."
"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 platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."
"It is an expensive solution."
"The only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"Dell PowerScale (Isilon) is an expensive solution."
"Our company finds the pricing high, but it decreases over time."
"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."
"It is not bad. It is like everything else. Pricing has gone up quite over the last couple of years, but everybody's pricing has gone up. For what they deliver, it is right in line with what everybody else has."
"The solution's pricing is on the expensive side."
"The pricing seems high on certain products and features, such as the audit feature of Panzura Data Services. They should consider more attractive pricing for companies of our size. The renewals are yearly, but the pricing is a little high for us."
"It's competitive. I don't know what competitors are charging, but they have been very transparent, which is nice, and we've negotiated to avoid percentage increases."
