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.

The Nimble CS-Series has proven to be reliable with 100% uptime

When we started the process of looking for a SAN vendor I had four primary criteria: reliability, performance, cost, and simplicity. We were really looking for a unicorn and were fully expected to have to make compromises in one of those areas. The Nimble CS-Series was recommended by our solutions provider, and we were blown away. Not only was it the most affordable option, but it was the easiest to deploy, had the best performance, and has proven to be reliable with 100% uptime.

Quotes from Members

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

Pros

"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."

"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."

"Once we solved the data reduction and what Pure does we were hooked."

"Pure Storage FlashArray has significantly improved our data center performance. It handles high workloads efficiently, providing better performance in the environment. With increased storage capacity, it has led to improved overall system performance. The tool's technology is a standout feature. It has helped me reduce storage costs by 15 percent."

"Pure Storage FlashArray simplifies maintenance and management with its intuitive GUI, making storage allocation and other processes easy to understand, even for beginners."

"I would recommend Pure Storage, as it is well-established."

"The most valuable feature of the Pure Storage Flash Array is the blazing fast monitoring."

"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."

More Everpure FlashArray pros

"Purchasing; We worked with a sales rep to purchase our Unity."

"Moving also from a hybrid to an all-flash array helped us to minimize footprints in our data centers."

"The stability is good, and we are very happy with the Unity; it does what it says it does and it performs, so you never have performance problems with it."

"I've had so many nightmares with so many other arrays, but I have no complaints with Dell EMC Unity at this time."

"The most valuable feature is the performance. It's still an all-flash array at a good price point."

"We have adopted the all-flash array; it eliminates all the overhead of tiering and a lot of the data structuring overhead involved, and it gives us a lot of operational efficiencies."

"When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good."

"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."

More Dell Unity XT pros

"We moved from CX with FC/SATA to VNX with SSD, SAS, NL-SAS and using SSD as Fast Cache we have seen huge performance gains in certain operations."

"Technical support is good."

"Not only was it the most affordable option, but it was the easiest to deploy, had the best performance, and has proven to be reliable with 100% uptime."

"One thing I would like to explicitly mention here is the EMC support; it is by far one of the best supports you will ever get in comparison with any vendor."

"Technical support is fast and always fixes the issues."

"The replicating of the entire storage unit to a different location was a very useful function."

"Customer Service: It's great. Technical Support: It's great."

"VNX 5200 works well with a medium VMware cluster, has good performance, and enables hardware disk replication."

More VNX [EOL] pros

Cons

"I would like to see data tiering to AWS."

"Pure Storage FlashArray has not helped decrease the total cost of ownership."

"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."

"The integration capabilities could be improved."

"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."

"The price is too high."

"In terms of improvement, Everpure FlashArray could have more attractive UI/UX design compared to other solutions."

"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."

More Everpure FlashArray cons

"We cannot connect directly with Dell due to sanctions."

"Include cloud-based replication for blocks"

"We have had customers reporting issues with slow responses from the support team."

"The solution should allow for connection and replication with other storage models such as HPE, IBM, and Hitachi."

"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."

"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."

"Dell operates at the commodity end of the market, so if they really want to get into storage in a big way, they need to have better pre-sales technical support and engagement."

"In the management interface, you can only create one LUN at a time."

More Dell Unity XT cons

"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."

"Yes, we have had issues. The system is limited by the number of enclosures."

"I think one area where we would like to see improvement is better deduplication and compression."

"They may change the disks from NL-SAS to Flash, but it would be costlier for customers."

"Customer Service: I don't like the way EMC's Powerlink support is behind a wall."

"As an entry level array, this is just right, but adding support for FAST-VP would be beneficial although that feature is available on the higher end VNXe3200."

"We actually had data loss from too many simultaneous drive failures on the 7500."

"I do not recommend the Gen 1 VNX to anyone in this day and age."

More VNX [EOL] cons

Pricing and Cost Advice

"The price of the solution is not expensive."

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."

"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."

"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."

"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."

"We have seen a reduction in total cost of ownership (TCO)."

"The solution is expensive."

"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."

More Everpure FlashArray pricing and cost advice

"Most licenses for the solution are free but upgrades are available when adding additional software or storage."

"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."

"Our costs are roughly $200,000 a year."

"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."

"Licensing is fine. We worked with a sales rep to purchase our Unity."

"From a pricing perspective, this solution is comparable to others on the market."

"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."

"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."

More Dell Unity XT pricing and cost advice

"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."

"Reducing dependency on JavaServer Pages (JSP) could improve the administrative overhead."

"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."

"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"

"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."

"Make sure you understand how the licensing works and that you are getting the right set of licenses if you need array-to-array replication."

"While EMC tends to be on the expensive side, the stability and support of their products are top-notch and I feel are worth the cost."

The VNX range is older and is being phased out. I think you mean VNX 5200? That said the Unity 400 is the better investment as it is newer, cheaper to support, faster, and with higher capacity and bigger supported file system size.
