Flexibility and reliability have supported seamless data growth
I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

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

"Dell PowerScale (Isilon) stability is solid as a rock."
"Dell PowerScale (Isilon) has powerful security, which makes it a very reliable storage solution for our content, and also the support and observability of our system; the call home feature is fantastic because when it presents an issue, Dell automatically opens a ticket regarding any warnings or alerts, allowing us to have a complete view of our system's health."
"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."
"Dell PowerScale overall is easy to use."
"The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed, which benefit my company by providing less downtime and less overhead."
"My experience when deploying Dell PowerScale (Isilon) was very straightforward, as we had Dell come on site to do all the actual setup, which was a big help."
"I would rate Dell PowerScale (Isilon) as a product a ten out of ten."
"What I like the most about Dell PowerScale (Isilon) is that the storage capacity is very high."
"Hitachi NAS Platform is very stable."
"The Hitachi storage platform is highly scalable and highly available."
"The pricing of this solution is good, which is an advantage that positions this product well."
"The reliability and scalability of Hitachi NAS Platform are valuable features."
"Hitachi is reliable with high availability and solid performance. It performs well regardless of the workload."
"Hitachi NAS has improved my storage operations significantly."
"The product has valuable features for data migration."
"The product’s technical support services are good."
 

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."
"I have escalated questions to the technical support team of Dell, and I find the support center to be very poor compared to what it was during EMC's time."
"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."
"The portal is really complicated to figure out features and functions, and it could be easier to navigate."
"Dell PowerScale (Isilon) certainly has room for improvement; since it does not provide SAN at the moment, I would look for Dell to create a complete unified solution just like NetApp."
"The improvement should be in AI. Everything is going towards AI."
"The UID mapping and how to configure mapping-related things is a struggle."
"The legacy file system for Epsilon didn't scale into the cloud and didn't have a separate OS. It would be key if this was made possible."
"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."
"Hitachi NAS Platform is expensive."
"The Hitachi NAS Platform is too complicated, not simple, and not cost-effective, sometimes being inappropriate for most situations."
"Hitachi NAS Platform's pricing could be reduced. It is high compared to other competitors."
"I would like to see the inclusion of support for cloud-connectivity to providers like AWS."
"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."
 

Pricing and Cost Advice

"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."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"The solution's licensing cost varies based on capacity and performance requirements."
"Our company finds the pricing high, but it decreases over time."
"It is an expensive solution."
"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."
"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."
"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."
"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."
"This solution is priced well and there are no costs in addition to the standard licensing fees."
"It is a highly-priced product."
"Costs are based on the features and it is a considerable amount."
