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.
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."
"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."
"It is stable and very user-friendly."
"PowerScale has made it extremely easy to scale file data across our organization. We have two implementations of Isilon. One is a replica of the other. When scaling, we add nodes to each location and expand the cluster. The process is straightforward."
"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."
"The capacity and scalability are what I appreciate the most about it; that was huge for us. We saw its benefits immediately after we started using it."
"This is the best platform that we could have for storage utilization. It is affordable and scalable. At the end of the day, it's something that we find very easy to use."
"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."
"The pricing of this solution is good, which is an advantage that positions this product well."
"The Hitachi storage platform is highly scalable and highly available."
"The product has valuable features for data migration."
"Hitachi is reliable with high availability and solid performance. It performs well regardless of the workload."
"There are no other NAS in the current market that can compete with Hitachi in terms of performance."
"The product’s technical support services are good."
"Hitachi NAS Platform is very stable."
"Simple and extremely reliable."
 

Cons

"The solution isn't suitable for small environments or small customers."
"The thing that they are working on now, and we are following closely is more native cloud integrations. The way that we envision workloads in the future is around moving compute to data instead of the other way around. So, we would like to have a single pane glass to manage storage across a variety of different platforms, including native cloud. That would be awesome."
"I would make Dell PowerScale (Isilon) better by improving SmartSync in the graphical user interface. Currently, everything has to be done through the command line, and I prefer having a graphical interface."
"Since our Dell PowerScale (Isilon) is our own on-prem in-house built system, we don't have many up-to-date resources, and we're still a few years behind."
"It is a bit higher priced than some of the other systems."
"The analytics could be improved."
"I would want to see more AI features with Dell PowerScale (Isilon)."
"Additional metadata reporting would be great. We have to use a separate tool to report on that. We would like to view the age of data and how long it has been since someone has accessed a file."
"I rated Hitachi NAS a seven out of ten, primarily due to the interface or insufficient improvements in certain areas."
"I would suggest that Hitachi make a NAS box that can work independently, without relying on SAN connectivity."
"Hitachi NAS Platform is expensive."
"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."
"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."
"Hitachi NAS Platform's pricing could be reduced. It is high compared to other competitors."
"The Hitachi NAS Platform is too complicated, not simple, and not cost-effective, sometimes being inappropriate for most situations."
"I would like to see the inclusion of support for cloud-connectivity to providers like AWS."
 

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."
"It is a really expensive solution."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."
"It's a high-cost offering amounting to three or four million Swedish kronor, or about $400,000 or euros, for approximately 480 terabytes of storage."
"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."
"Hitachi NAS Platform’s price is high and depends on SCSI disc capacity."
"Costs are based on the features and it is a considerable amount."
"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."
"It is a highly-priced product."
