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

"My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."
"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."
"The solution is extremely easy to manage. This is its most valuable feature."
"The most valuable feature is its single space of storage."
"Dell PowerScale includes a wealth of features that are important from a security and recovery perspective."
"The technical support has been excellent. I would give them a ten out of ten for support."
"The most valuable feature of the solution is its performance."
"The reliability and stability of Dell PowerScale (Isilon) is good, with no downtime."
"Simple and extremely reliable."
"The Hitachi storage platform is highly scalable and highly available."
"The most valuable feature is its ability to handle a high number of users while maintaining both stability and performance."
"The reliability and scalability of Hitachi NAS Platform are valuable features."
"The product has valuable features for data migration."
"Hitachi NAS has improved my storage operations significantly."
"The pricing of this solution is good, which is an advantage that positions this product well."
"Hitachi NAS has improved my storage operations significantly."
 

Cons

"We lost our technical sales reps about two years ago. We haven't gotten one assigned to us and we'd love to have one."
"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."
"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."
"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."
"We see room for improvement in Dell PowerScale (Isilon) because we need personnel to effectively utilize all our infrastructure; it's not easy to find skilled people to work on AI and data analysis."
"The analytics could be improved."
"The price always has room for improvement."
"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."
"For the Hitachi NAS Platform, the tools are basic and don't provide much insight."
"There are insufficient improvements in certain areas."
"The Hitachi NAS Platform is too complicated, not simple, and not cost-effective, sometimes being inappropriate for most situations."
"The monitoring tool is not well developed."
"I would suggest that Hitachi make a NAS box that can work independently, without relying on SAN connectivity."
"I encounter challenges while installing the upgrades for the product."
"Hitachi could be more flexible and have a simpler management interface."
"I would like to see the inclusion of support for cloud-connectivity to providers like AWS."
 

Pricing and Cost Advice

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"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."
"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."
"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 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."
"Dell PowerScale (Isilon) is an expensive solution."
"The solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."
"It is a highly-priced product."
"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."
"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."
