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.

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 assists with eliminating storage silos because it provides SMB and NFS protocols. PowerScale has also helped free up our employee's time to focus on other business priorities."

"Ability to scale the number of nodes without having to build additional clusters."

"The most valuable feature is its single space of storage."

"The most valuable feature of Dell PowerScale is its scalability."

"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."

"Dell has the AI to protect the EMA."

"On a scale of one to ten, with one being worst and ten being best, I would rate Dell PowerScale (Isilon) a ten."

"Isilon is flexible in supporting various data workloads while keeping them protected. Dell continues to release updates and patches which enhance the use of this solution. This includes offering ransomware protection."

More Dell PowerScale (Isilon) pros

"It creates a NAS environment on top of Hitachi SAN, which facilitates customers who need NAS protocols along with their existing SAN portfolio."

"Hitachi is reliable with high availability and solid performance. It performs well regardless of the workload."

"The product has valuable features for data migration."

"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."

"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."

More Hitachi NAS Platform pros

Cons

"The solution is expensive. It's quite expensive for the amount of storage we have."

"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."

"Dell PowerScale (Isilon) could improve in terms of having some problems with using IPv6 and IPv4 on the same namespace at the same time, which is one of our biggest problems as you have to do some really bad workarounds to get that working."

"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."

"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times."

"They should add some new services that should be for on-premises, and more analytics should be there for the data, allowing for a deep dive from that analytics, which is currently missing."

"Dell's customer service needs improvement. Specifically, hardware failures under warranty should be addressed within the promised timeline."

"We used to have a chat feature available on the support site. It's not available to us anymore."

More Dell PowerScale (Isilon) cons

"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."

"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."

"For the Hitachi NAS Platform, the tools are basic and don't provide much insight."

"I would like to see the inclusion of support for cloud-connectivity to providers like AWS."

"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 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."

More Hitachi NAS Platform cons

Pricing and Cost Advice

"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 pricing for this solution is reasonable."

"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."

"Dell PowerScale is an expensive solution compared to other products like Qumulo."

"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."

"Our company finds the pricing high, but it decreases over time."

"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."

"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."

More Dell PowerScale (Isilon) pricing and cost advice

"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."

"This solution is priced well and there are no costs in addition to the standard licensing fees."

"It is a highly-priced product."
