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.

The creators of Qumulo were the ones who created Isilon, and I had a conversation with them, so any of the features within Isilon may need tweaking, but I think they resolved it here. In the year that I worked with it, I did not see anything that I had an issue with. The security is great, and it works with cloud technologies, being a hands-based tool, so you can use it with AWS or Microsoft Azure. It programs very easily. There are REST APIs, and there is a cloud connection. The management and program layer is made up of three capabilities: API, the command line, and a visual interface. In the year that I worked with it and brought it in, I think it has been effective. The only thing I would like to see added to Qumulo is for the interface to improve visually, more in line with vCenter, but that is just my thought. Overall, I appreciate it.

Quotes from Members

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

Pros

"They are quite responsive and our local team was pretty good."
"Reliability and performance are its most valuable feature."
"When we needed to replace the other arrays, we went straight to Pure and life-cycled them into Pure in every segment we have."
"The features that are there now are really what we need."
"It is easy to deploy and it's all-flash, so it's very fast."
"Pure Storage has the right business model and will be around for a long time."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"It has improved my organization in the way that we have high reliability and faster access to our data."
"The performance, overall, is quite impressive."
"My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."
"Dell PowerScale's performance is good."
"Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."
"The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once."
"I feel that the reliability and availability of Dell PowerScale have positively affected my company's data operations as it's running stably, and we haven't had service outages or anything of that nature, so it's been very helpful."
"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."
"The features of Dell PowerScale (Isilon) that I prefer the most include some of the newer technologies that are on it, which would include SmartSync and the ability for the data mover to continue to make incremental changes."
"The most valuable features of Qumulo are the ease of management and special permissions that are quick to enable. The overall performance of the solution is good."
"Overall, I would rate Qumulo a nine. I appreciate that it does snapshots, and you could use replication."
"The ratio of total operational cost to complexity versus feature set is very good."
"The most valuable feature is real-time analytics."
"The feature that I like most is the analytics part of the file system."
"The most valuable feature is real-time analytics."
"It is a very stable product. I never faced any issues."
"The ratio of total operational cost to complexity versus feature set is very good."
 

Cons

"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"I would like to see support for NVMe, end-to-end."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room."
"It's expensive, but you get what you pay for."
"Sometimes, it takes too long to set up everything. That's something I would want them to improve."
"Pricing is an issue. It's quite expensive for the amount of storage we have."
"Dell PowerScale (Isilon) is a little bit pricey, and its pricing could be improved."
"PowerScale is not suitable for virtual environments."
"Dell's customer service needs improvement. Specifically, hardware failures under warranty should be addressed within the promised timeline."
"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."
"I believe the support engineers need to improve their skills."
"The downside of Dell PowerScale (Isilon) is that if we are replacing a drive, sometimes in the worst-case scenarios, some of the other drives will also go to the SmartFail state."
"The price of the software is a bit expensive, so a reduction in cost would make it more competitive."
"In the future, I would like to see non-disruptive updates."
"The price of the software is a bit expensive, so a reduction in cost would make it more competitive."
"In the next release, I would like to see the ability to have more control at a terminal level of the file system."
"The solution could improve availability and improve data protection or data services such as compression of deduplication."
"Qumulo should continue to expand automation and orchestration capabilities."
"Qumulo should continue to expand automation and orchestration capabilities."
"The solution could improve availability and improve data protection or data services such as compression of deduplication. In a future release, we'd like to have more cloud API integrations."
 

Pricing and Cost Advice

"It is cheaper than NetApp."
"We feel that the pricing is fair and the licensing process was easy for both."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"There is always room for negotiation."
"The price of Pure Storage FlashArray is expensive."
"There are no fees for licensing. The hardware is paid for only once."
"Pure came in at a better price point than EMC and performed better than Compellent."
"We have seen a reduction in TCO."
"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 pricing for this solution is reasonable."
"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."
"Dell PowerScale (Isilon) is an expensive solution."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"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."
"It is an expensive solution."
"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 price of the solution is in the middle range compared to others. We look at the price per terabyte."
"The price of Qumulo is reasonable."
