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

"They have really good baked in analytics to show you trends for growth history, so it does help with future planning for data growth."
"One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."
"The stability and performance are the best things about the solution."
"Data reduction and compression. Sub millisecond latency."
"Cuts VM deployment down to seconds and cuts latency under MS with amazing performance and very stable operation with no worries about how much it can handle."
"When users don't call wanting to kill me, that's ROI."
"Pure Storage is an amazing solution."
"Using this solution has improved our consolidation ratio and it saves us a lot of space."
"We use replication for disaster recovery (DR), making our DR process much easier."
"I like that the performance is very good."
"Dell EMC Unity is actually one of my market focuses, from the understanding that Dell EMC has redefined the core of their mid-range storage portfolio, focusing on two main products: Dell EMC SC (Dell legacy Compellent) and Dell EMC Unity (the last mid-range storage solution developed by the former EMC, just prior to committing the fusion with Dell)."
"For our environment just having a solid, running box is really sufficient."
"The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"We are replacing legacy hardware and hardware that is going out of support, and we are consolidating two or three systems into one."
"The All-Flash models are intuitive and easy to work with, in addition to providing high IOPS with low latency to support Business Critical applications."
"It is a good product with a simple setup and easy administration."
"It’s very stable in all the years I've worked with it, I know it’s stable and the support is there."
"Stability has been rock solid, as we have been running both units for over two years with no major problems."
"It is a great product: scalable, reliable, and robust."
"It would be a good choice for midrange businesses due to the performance/features and cost."
"If you have a banking and finance domain, then go for EMC products as they offer better performance and scalability."
"EMC storage has the best performance and functions."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
 

Cons

"I would like to see more cloud integration."
"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."
"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"I would love for them to have a hyper-converged solution."
"Going forward, don't complicate things for the customers."
"The only thing is that we've had to upgrade controllers a few times because we ended up wanting to use more stuff on here."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"Pure Storage FlashArray could improve by being more secure."
"Scalability of this solution could be improved."
"The user interface could use improvement."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult."
"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."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"Unity only does compression. It would be nice if there was a deduplication feature as well."
"The initial setup is not so straightforward if you don't have experience with storage arrays."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"If the VNX had embedded encryption, that would be great."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"It only supports 10Gb copper, and cannot do 10Gb fiber."
"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."
"There were scalability issues, the scalability options are limited due to supported SSD."
 

Pricing and Cost Advice

"There are no licensing fees aside from the support."
"It could always be lower, but it's okay."
"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"The price was more favorable than Dell EMC."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"I rate Dell Unity XT’s pricing a nine out of ten."
"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"
"It is priced at around or under $50,000."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
"It is an average priced solution."
"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."
"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."
"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."
"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."
"​Reducing dependency on JavaServer Pages​ (JSP) could improve the administrative overhead.​"
"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
"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 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.
