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.

Ease of implementation and robust performance enhance multi-OEM support experience

We are limited only to hardware replacement, not administration tasks. We work on AMC products through Annual Maintenance Contracts. We provide support up to the 680 model. The XT680F is a newer model, and we support from 380F to 680F. The FlashSystem 8000 series is all-flash, and there is also a 5000 series flash model. We can compare IBM DS series, including the 8000 series for recommendations. For NetApp, we can recommend the FAS 8000 series.

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

"Overall, Pure Storage FlashArray has never let us down in front of customers so far."

"This storage has to be the most well thought out and effective storage that I have had the privilege to work with."

"This is the best all-flash storage array on the market."

"It has improved my organization in the way that we have high reliability and faster access to our data."

"The most valuable feature is the speed of it, as it is much faster than anything that we can get from similar competitors, and the solution helps to simplify storage."

"Deduplication is an excellent feature. I also like the NAS and support."

"Pure Storage FlashArray has helped decrease the total cost of ownership because we know what the cost is going to be every year; we don't get any hidden fees or upgrade fees, everything is included in the price."

"At this point, I don't know anything that they could provide in a better way."

More Everpure FlashArray pros

"The Unity XT box is very strong. It doesn't break. The MTBF time is very large so you don't have to worry about faults or outages in your operations."

"It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing."

"The solution overall has high performance."

"When comparing them all in their strengths for implementation, the lifecycle of the product, and the support they provide, I would rank Dell number one, IBM second, and third would be Fujitsu."

"Their product is stable."

"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."

"The biggest improvement is the data reduction for the organization; that is where they see the better TCO and improved ROI for their existing footprint."

"This solution helped us reduce our physical footprint and power consumption."

More Dell Unity XT pros

"It is very stable even during multiple power failures."

"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."

"Integration with VMware"

"If you have a banking and finance domain, then go for EMC products as they offer better performance and scalability."

"The replication feature provides another functionality to protect your data."

"It is very stable, even during multiple power failures."

"Multi-tiering, positively affects the efficiency of the storage space."

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

More VNX [EOL] pros

Cons

"The file functionality could be better."

"Awareness about Pure Storage needs to increase. Currently, people mostly think of Dell and NetApp when it comes to storage."

"I can't see where they can make anything better, unless, of course, they lower their prices even more."

"The only issue is the pricing. Because we have competition, our customers always take another brand and say they can save their investment."

"The technical support is okay, but could be improved."

"It doesn’t provide enough information on performance analytics. For example, Nimble Storage has Infosight, which provides data; Pure Storage doesn’t have an equivalent."

"I would love for them to have a hyper-converged solution."

"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."

More Everpure FlashArray cons

"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."

"The price of this product can be more cost-effective."

"There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."

"Support Responsiveness & time to fix bugs should be improved."

"Maybe deduplication would be something that would be better to have."

"The storage processors have less port expansion than previous high-end VNX arrays. Data compression is only available in all-flash pools."

"The interface and configuration could improve."

"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree."

More Dell Unity XT cons

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

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

"The performance impact snapshotting had on the cluster was enormous. The entire cluster performance took a performance impact of about 30% as soon as we created one snapshot of all the volumes created on the cluster."

"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."

"Due to very complex structure and sophisticated architecture, it needs experts for trivial troubleshooting also."

"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."

"There is an easy replication process between distinct data centers via VPLEX and/or RPA. But I hope in the future that EMC/Dell could replicate this with other types of storage."

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

More VNX [EOL] cons

Pricing and Cost Advice

"It's priced higher than the market."

"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."

"The price is very reasonable when compared to other solutions."

"Our costs are around $100,000."

"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."

"For us, as the customer, it reduced the price of the management."

"I don't know the exact cost but it's around $1,000."

"While it comes with a higher price tag, this investment often translates to significant improvements in performance."

More Everpure FlashArray pricing and cost advice

"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise. Huawei and Lenovo are very price competitive. Looking at the price point for a country like Sri Lanka, where we have a very low economy, I think you need to look at a pricing mechanism that is a bit more flexible."

"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."

"We checked both HP and Dell and we determined that Dell EMC was a better option."

"The solution is extremely functional for the price that we pay for it. It is worth the investment."

"The ROI is right where we need it to be. It's a reasonably priced array."

"While Dell EMC is costly, I don't have any complaints about their licensing model."

"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."

"The solution should be cheaper."

More Dell Unity XT pricing and cost advice

"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."

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

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

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

"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."

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

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

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.
