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
HPC CTO at a manufacturing company with 10,001+ employees
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

"Cost, racial per terabyte, and speed is why we chose PureStorage. It was no brainer."
"If you need faster storage and a good product, this is the one you should go ahead with."
"The best feature is consistently lower latency, even when IOPS crank up to over 75K, and the product maintains submillisecond response time, which is incredible."
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"I recommend this solution for production because it has good performance and capacity management."
"It is the SAN backbone for our company."
"The speed is the most valuable feature, along with the ease of getting it connected. We were able to get it online in less than a day."
"For me, right now, it is the best storage solution in the market, by far."
"For all the deployments that I've seen or done, its been a rock solid platform."
"It's definitely scalable, definitely fits the majority of our use cases, in high-performance environments such as Oracle, SQL, and so forth."
"I can mix and match the drives, using older mechanical devices and the latest SFP drives in a single solution with different enclosures."
"I definitely recommend Compellent to my customers because it is a very good product that is very scalable, it is easy to use, and Dell offers a good warranty."
"Technical support is really good. We have had good, high-quality support with our SC Series."
"It helps us streamline deployment of VMs."
"We have zero downtime."
"It had many features, like a snapshot, replication, on-the-file RAID levels, mix-and-match files, those kinds of things."
"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."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure."
"They can also include file services such as NAS shares and CIFS shares. There should be provisioning of the file shares from a unified array."
"Pure Storage can improve FlashArray by providing more logging visibility to customers. Currently, there is no log visibility."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve."
"There was some complexity in the initial setup."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten."
"We haven't seen ROI yet."
"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."
"I would like to see an integrated key manager in the controllers. Currently, it's an external product."
"Technical support should respond more quickly because the turnaround time is very high."
"In terms of additional features, I would like to see some kind of I/O meter, to indicate what we are using in terms of performance. I would like to see automation with that, where it would give me the trends. I want to know those things easily, to help me know where issues are going to occur."
"The tool's pricing is high and not suitable for medium companies."
"The lower model, the 3000, should have duplication. It doesn't right now. It's only from 5000 that this is offered, but it depends on the performance. It could be they don't offer it on lower models because the duplication is too much of a burden to the performance."
"This solution could be improved if overall performance was improved and operated with a higher speed and supported a higher volume of RAM."
"Matching color coding during zoning is sometimes a little bit annoying."
"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."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
 

Pricing and Cost Advice

"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."
"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
"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."
"There are no licensing fees or other costs."
"Pricing is moderate. It is neither cheap nor expensive."
"The price is reasonable."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"We have reviewed many platforms over the years. It is probably the best solution for its value."
"The pricing is reasonable, but it is expensive."
"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."
"This product is too expensive compared to others, and I don't see any value in using it."
"The maintenance is usually pretty good. It's not like some of the others where they increase it in the fourth, fifth, or sixth years."
"The SC Series was priced fairly. I wouldn't call it either expensive or cheap because we had a very tight budget, so if they were able to fit in that type of budget, they met our expectations."
"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."
"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."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
