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

"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."
"The speed is one of the most valuable features of Pure Storage FlashArray."
"The stability is perfect, the reliability is 100%, and the latency is always lower than 1 millisecond."
"If you're interested in using this solution, I recommend that you do the same — see if you like it."
"There was a dramatic improvement in operating costs just as a result of the environmentals and space, let alone the cost of the unit itself."
"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"The best features of Pure Storage FlashArray are its ease of use and user-friendly interface, and the performance allows all types of services to be visualized from a single point of interface, making it more robust and user-friendly."
"With the SC Series SAN, the performance that we've gotten out of the boxes alleviated anyone's concerns."
"Connecting it up, you can run it within a few hours."
"A valuable feature is the performance of the auto-tiering. It will move hot data up to your fastest Tier 1 or move your slow data down. Data progression is what it's called. With the auto-tiering you can have multiple tiers, you can have your Tier 1 be either spinning or flash, all the way down to 7.2K. It will change the RAID on the fly so your writes come in at RAID 10. After they sit for a while, they get converted to RAID 5, then they'll cool off and move down the tiers. Your performance is kept going, while the cold data is moved to your slow, non-performance tiers."
"The product offers good performance and is quite powerful."
"It helps us streamline deployment of VMs."
"Technical support is very good. I do use it from time to time and it's always excellent."
"Most valuable features have been the system customization with it, the performance you receive, and their CoPilot Support (or Dell EMC Storage Support)."
"I would recommend to buy Dell EMC 3020 to anyone researching these type of solutions."
"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."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"Pure Storage had operational challenges between 2016 to 2018, impacting perceived reliability."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"It took us a year to get it to stabilize and to get the best out of Pure."
"We would always like to see higher performance, and lower pricing is always better."
"The price of the solution can improve."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"Overall, I'd like to see more synergy between Dell EMC's higher-tier platforms and their mid-tier platforms."
"If Dell SC Series could have supported the protocol NVMe over TCP, that would have been great. It does not."
"Snapshots in VMware. You can’t do snapshots since the storage itself does that. Therefore, some apps (Veeam, for example) don’t work well with this kind of tiering storage."
"This product should be a lot more user-friendly."
"This solution could be improved if overall performance was improved and operated with a higher speed and supported a higher volume of RAM."
"The administration and support (on the way that they delivered) was a little bit slow."
"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."
"We can definitely see a need for it being a multi-controller system for customers who want to scale beyond the current capability."
"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

"We have seen a reduction in total cost of ownership (TCO)."
"It is cheaper than NetApp."
"It could always be lower, but it's okay."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"Pricing is very competitive, and it's better than other competitors."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"I would prefer that they lower their pricing."
"We purchased a license to use this solution and we pay for the storage ourselves."
"It's a very affordable solution."
"We have the basic license for the use of this solution and it is a permanent license. The overall cost could be less, it is expensive."
"The pricing is reasonable, but it is expensive."
"The pricing of this solution is competitive."
"We were able to afford two tiers of flash storage at a price where the competition was giving us one tier or just a handful of discs."
"Compared to other solutions out there, it's affordable."
"It has a good price point and offers some value-added enterprise features."
"Pricing depends on varying life cycles."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
