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

"It is stable and very user-friendly."
"The solution allows me to use SSMDS to store data for end users and share it within different locations."
"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."
"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle."
"The solution is stable."
"The tool's most valuable features are high density and scalability."
"We use the solution internally to support our own managed servers and run our own support center."
"The product has valuable features for data migration."
"Simple and extremely reliable."
"Hitachi NAS has improved my storage operations significantly."
"The Hitachi storage platform is highly scalable and highly available."
"Hitachi is reliable with high availability and solid performance. It performs well regardless of the workload."
"The most valuable feature is its ability to handle a high number of users while maintaining both stability and performance."
"Hitachi NAS Platform is very stable."
"The reliability and scalability of Hitachi NAS Platform are valuable features."
 

Cons

"The improvement should be in AI. Everything is going towards AI."
"Pricing is an issue. It's quite expensive for the amount of storage we have."
"The price always has room for improvement."
"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."
"Sometimes, it takes too long to set up everything. That's something I would want them to improve."
"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going. That's a little bit of a ding that we have on it. It does so much magic in order to protect itself from drive failures or multiple drive failures, that it automatically handles the provisioning and storage of your data. But by doing that, finding out why a file of a certain size, or a directory of a certain size, is using more storage than is being reported in InsightIQ, is very difficult to discern."
"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."
"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."
"The monitoring tool is not well developed."
"Hitachi NAS Platform is expensive."
"I would like to see the inclusion of support for cloud-connectivity to providers like AWS."
"The Hitachi NAS Platform is too complicated, not simple, and not cost-effective, sometimes being inappropriate for most situations."
"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 rated Hitachi NAS a seven out of ten, primarily due to the interface or insufficient improvements in certain areas."
"I encounter challenges while installing the upgrades for the product."
"I would suggest that Hitachi make a NAS box that can work independently, without relying on SAN connectivity."
 

Pricing and Cost Advice

"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"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."
"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."
"Pricing for this solution is reasonable."
"The pricing for this solution is reasonable."
"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."
"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."
"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."
"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."
"It is a highly-priced product."
"Hitachi NAS Platform’s price is high and depends on SCSI disc capacity."
"I would rate the solution's pricing six to seven out of ten."
