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.

User interface offers clarity and detailed information while technical support consistently delivers
The best features of Dell SC Series are stability and replication. The replication solution is excellent, and they have a solution named Live Migration. It is a robust platform. The interface and the GUI (graphical user interface) for administrating the Compellent are exceptional, with abundant information that is very clear. The management capabilities are excellent, and the stability of our storage hardware is remarkable.
Alan Powers - PeerSpot reviewer

Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"It has a small footprint, as the current system is only four units per rack, it's got good speed for the price as it uses eMLC, an advanced type of SSD, and it's very scalable, and we're not paying for capacity as we get free controllers every three years."
"I would highly recommend this solution; it has all the features we need and tests all the software solutions that are currently available and that will be available in the future."
"I appreciate the ease of provisioning storage on Pure Storage FlashArray."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage; the ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"From an investment standpoint, the support staff I require for it is greatly reduced, so I don't have the in-depth requirements that I had on other products."
"I like the performance. Performance-wise, it accommodates the needs of highly-critical servers. It is reliable."
"We put a fair amount of stress on it because we run sequel workloads and we run web applications where the same web files are hit over and over. We have had almost zero stability issues with that SAN, that has been really great for us."
"The biggest lesson that I have learned from using Pure FlashArray is that it's user-friendly, easy to manage, and very flexible."
"It has given us a reliable and dynamic storage system that we did not match before with our previous solution."
"For all the deployments that I've seen or done, its been a rock solid platform."
"The solution is stable."
"The most valuable feature is the customer support."
"When it comes to mid-range storage solutions, it's usually our preferred solution, from all-flash all the way up to hybrid solutions too."
"Most valuable features have been the system customization with it, the performance you receive, and their CoPilot Support (or Dell EMC Storage Support)."
"It had many features, like a snapshot, replication, on-the-file RAID levels, mix-and-match files, those kinds of things."
"Technical support is really good. We have had good, high-quality support with our SC Series."
"This has been one of the most reliable storage systems that I have ever used."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
 

Cons

"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."
"I wish they could collaborate more with the other vendors internally, instead of us opening cases with Cisco, HPE, VMware, etc."
"FlashArray could improve on the administrative side. For example, when you need to upgrade the boxes, we can't do that ourselves. We need to open a ticket with support and have them do that for us. You don't need to be on the call with them. We tell them we have a slot that we want to upgrade, and they send us an email when it's done."
"Some of the issues are that it's probably not on a par with other large storage enterprise type products."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"Currently, we are not using this solution extensively because it's becoming a sunset solution."
"The interface could be improved. It should have an application point of view."
"I would like to see an integrated key manager in the controllers. Currently, it's an external product. It would be nice to have the option of having a built-in key for self-encrypting drive features."
"Dell SC Series is no longer available, while Dell PowerStore, which supports NVMe over TCP, is different and not very affordable."
"I would rate the SC Series at seven out of ten right now. That might change as future releases come out and more functionality comes into the product."
"The cost of the solution could be better."
"This product should be a lot more user-friendly."
"We have seen some degraded throughput with mixed workloads. We have been working with Dell EMC to correct some of these latency issues."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
"The write performance could be improved because it is less than half of the read performance."
 

Pricing and Cost Advice

"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"Its price is almost double than any other flash storage solution."
"We have seen a reduction in TCO."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"Pure Storage FlashArray's pricing is very competitive."
"We have seen a reduction in total cost of ownership."
"This solution could be better priced in comparison with other vendors."
"It has a good price point and offers some value-added enterprise features."
"The scalability seems a bit more expensive than even buying a brand new one so far. That has been kind of a drawback."
"It's absolutely affordable. Again, not having to do a forklift upgrade like some of the others have had to do in the past, it's very affordable for our customers and they continue to buy."
"Compared to other solutions out there, it's affordable."
"There are costs involving the solution, vendor fees and product safety which are additional."
"The pricing of this solution is competitive."
"This product is too expensive compared to others, and I don't see any value in using it."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
