Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

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.

Enables seamless file distribution while benefiting from scalability but could use simplified implementation
IBM Storage Fusion is used in telecoms. It is a file center that receives and shares files. It is also used for writing the CDR zone on the storage, since it offers a cost-effective solution for large-scale storage needs in a telecom setup The deployment of Storage Fusion has been new for us in…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"With this program, all of our applications are able to perform faster and this enables us to provide faster platforms and services to our customers and employees."
"The amount of data that I have moved to it from legacy storage has enabled us to retire units that are three or four times the physical size."
"Even if they weren't one of the fastest arrays in the entire industry, I would use them for their support model and ease of use."
"Pure Storage FlashArray has helped decrease the total cost of ownership because we know what the cost is going to be every year; we don't get any hidden fees or upgrade fees, everything is included in the price."
"The deduplication and compression rates are beyond impressive."
"It does efficient work of storing data while still delivering the performance that you would normally expect from a higher priced solution."
"It has been quite satisfactory in performance and scalability."
"It makes things ten times easier."
"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."
"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."
"You plug in a new node and data starts migrating over to it, and IT spreads out the load. We've added multiple nodes to the system since deploying it. The process is pretty seamless, and we are able to do it with no downtime. It's a very easy process to do."
"Dell PowerScale helps in saving costs related to power and rack space, reducing physical hardware from over one hundred to twenty-nine chassis."
"Dell PowerScale (Isilon) is brilliant for scalability and really, really good in that regard."
"I rate Dell PowerScale (Isilon) a ten out of ten, and we continue to keep buying it."
"The major advantages include data protection, ransomware protection, and cloud capabilities, and the primary advantage is the ability to use the entire cluster in one unified file system, which is a feature I have not observed in other products."
"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."
"Fusion provides the ability to install the secret server and distribute files; it serves as a black box where tickets are opened only if issues arise, reducing frequent upgrade problems."
 

Cons

"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"The initial setup of the product is complex."
"We haven't seen ROI."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"The difference in pricing could become a problem for Pure because the commoditization of the solutions could lead to a different price being a problem."
"They have a product, FlashBlade, which is their object storage integration, and that's something that we haven't integrated with yet. This might be an area for additional focus as it would play into scalability, because the very nature of object storage is that it's infinitely scalable."
"The deployment of Dell PowerScale (Isilon) is not really complex but depends on the hardware deployment."
"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."
"It is a bit higher priced than some of the other systems."
"The solution's rate structure or rate redundancy needs to be improved."
"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 legacy file system for Epsilon didn't scale into the cloud and didn't have a separate OS."
"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."
"Dell PowerScale (Isilon) is a bit expensive compared to other products."
"The implementation is complex, especially when using custom servers."
 

Pricing and Cost Advice

"We purchased a license to use this solution and we pay for the storage ourselves."
"Pricing is moderate. It is neither cheap nor expensive."
"The price is too high."
"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."
"It is light years beyond anything else with the same price point."
"It could always be lower, but it's okay."
"FlashArray is expensive, but the quality justifies the price."
"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
"The price of the solution is high."
"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."
"Dell PowerScale (Isilon) is an expensive solution."
"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."
"Pricing for this solution is reasonable."
"The pricing for this solution is reasonable."
"It is a really expensive solution."
"The price of Dell PowerScale (Isilon) is reasonable."
