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

"The solution allows me to use SSMDS to store data for end users and share it within different locations."
"My advice to other companies considering Dell PowerScale (Isilon) is that it takes a little time to understand the product, but once you have it set up and running, it will run stable for all its lifetime."
"The most valuable feature for me is SyncIQ."
"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."
"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."
"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 single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
"Features like ransomware protection, file lock retention, and third-party integrations (e.g., Superna for ransomware protection) are significant benefits."
"The product’s technical support services are good."
"The most valuable feature is its ability to handle a high number of users while maintaining both stability and performance."
"Hitachi NAS has improved my storage operations significantly."
"Hitachi is reliable with high availability and solid performance. It performs well regardless of the workload."
"The Hitachi storage platform is highly scalable and highly available."
"The reliability and scalability of Hitachi NAS Platform are valuable features."
"The pricing of this solution is good, which is an advantage that positions this product well."
"There are no other NAS in the current market that can compete with Hitachi in terms of performance."
 

Cons

"We're still fairly new with it. It's been a pretty positive experience thus far. However, they could improve implementation, as we had to rack and stack it ourselves."
"The price always has room for improvement."
"Dell PowerScale needs to reduce its price."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"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."
"Data storage performance needs to be improved."
"The product itself is capable of very much, but the initial deployment experience can be lacking possibly because it does not incorporate any design phase."
"I would like to see the inclusion of support for cloud-connectivity to providers like AWS."
"Hitachi NAS Platform's pricing could be reduced. It is high compared to other competitors."
"Hitachi NAS Platform is expensive."
"There are insufficient improvements in certain areas."
"Hitachi could be more flexible and have a simpler management interface."
"I rated Hitachi NAS a seven out of ten, primarily due to the interface or insufficient improvements in certain areas."
"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."
"I encounter challenges while installing the upgrades for the product."
 

Pricing and Cost Advice

"Our company finds the pricing high, but it decreases over time."
"Dell PowerScale is expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."
"It is an expensive solution."
"The pricing is excellent."
"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 paid an additional fee to have Dell's ProDeploy Plus team implement it."
"Pricing for this solution is reasonable."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
"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."
"Costs are based on the features and it is a considerable amount."
"I would rate the solution's pricing six to seven out of ten."
