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.
Mir Gulzar Ahmed - PeerSpot reviewer
Needs standalone functionality but provides a robust NAS solution for existing SAN environments
I would suggest that Hitachi make a NAS box that can work independently, without relying on SAN connectivity. The current solution only suits customers who already have a Hitachi SAN environment and want to add NAS protocols like NFS and CIFS. It's not suitable for customers without an existing SAN, as they would first need to acquire the SAN infrastructure before adding NAS functionality.

Quotes from Members

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

Pros

"The most valuable feature of Dell PowerScale is its scalability."
"For maximizing storage utilization, PowerScale is great. When you write the data to it, it spreads it out to all the nodes, so you get all the performance from the entire pool."
"The solution has simplified management by consolidating our workloads. Rather than managing all the different workloads on different storage arrays, Windows Servers, etc., we just have one place per data centre where we manage all their unstructured data, saving us time."
"The tool's most valuable features are high density and scalability."
"The most valuable feature we started using, beyond the initial scope for the solution, is the multi-protocol system that allows you to access the same set of files using different network protocols like NFS or SMB. PowerScale’s Unified Permission Model ensures that data security and access permissions are honoured regardless of whether the client is a Windows desktop or a Linux server"
"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"The most valuable feature is its single space of storage."
"Eyeglass is used to monitor for malware, which is very useful for us."
"The Hitachi storage platform is highly scalable and highly available."
"It creates a NAS environment on top of Hitachi SAN, which facilitates customers who need NAS protocols along with their existing SAN portfolio."
"Hitachi is reliable with high availability and solid performance. It performs well regardless of the workload."
"Hitachi NAS Platform is very stable."
"The product has valuable features for data migration."
"Simple and extremely reliable."
"Hitachi NAS has improved my storage operations significantly."
"The pricing of this solution is good, which is an advantage that positions this product well."
 

Cons

"The cost of Dell PowerScale is currently high and there is room for improvement."
"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."
"Its configuration needs to be more straightforward."
"The biggest weakness is small file handling. Small file compression options are not enabled out of the box. It would be good to have this enabled by default."
"The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path."
"Data storage performance needs to be improved."
"PowerScale is not suitable for virtual environments."
"I'd like to see more Iceland products in the cloud so that we can port our data into different environments if needed. I would also like to see a virtual appliance or software-defined Iceland product."
"The Hitachi NAS Platform is too complicated, not simple, and not cost-effective, sometimes being inappropriate for most situations."
"There are insufficient improvements in certain areas."
"I would like to see the inclusion of support for cloud-connectivity to providers like AWS."
"Hitachi NAS Platform is expensive."
"I encounter challenges while installing the upgrades for the product."
"Hitachi NAS Platform needs to improve by offering a unified storage solution. Due to budget constraints in regions like Southeast Asia, customers prefer a single machine that can handle all problems, which the current platform does not provide."
"The monitoring tool is not well developed."
"I do not like Hitachi NAS because it's an old-school NAS solution, compared to the other, newer-type solutions such as Isilon from Dell or Qumulo."
 

Pricing and Cost Advice

"Our company finds the pricing high, but it decreases over time."
"It is an 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 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 product with a high storage capacity suitable for large data requirements."
"The pricing is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."
"Dell PowerScale (Isilon) 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."
"Hitachi NAS Platform’s price is high and depends on SCSI disc capacity."
"This solution is priced well and there are no costs in addition to the standard licensing fees."
"I would rate the solution's pricing six to seven out of ten."
"Costs are based on the features and it is a considerable amount."
"It is a highly-priced product."
