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

"It reduces space and the polar consumption. It also accelerates the application."
"It has improved my organization because now have lower latency, we get fewer complaints from customers, and we see a constant response time."
"We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent."
"I like the performance. Performance-wise, it accommodates the needs of highly-critical servers. It is reliable."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"It has improved my organization in the way that now we have lower latency, we get fewer complaints from customers, and we see a constant response time."
"Despite the overuse of buzzwords and re-classifications, the storage industry has actually seen dramatic improvements over the last 3-4 years."
"We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency."
"Purchasing; We worked with a sales rep to purchase our Unity."
"We can put all the virtualized servers in one place, so our customers can share and manage the devices very easily."
"Once it is set up, it is definitely easy to manage."
"Via a click, we can deploy a data store or LUN to the ESX host. We can also deploy VVOLs to the ESX server."
"We saved money by moving off old storage and we gained extra capacity and speed."
"EMC is known for its reliability This product is good It is easy to install and maintain It operates with low maintenance and manpower costs"
"I like its performance and support."
"I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it."
"I really value deduplication and compression to save space."
"In a banking environment, on which we required a very high throughput for our database, we have used this product and our desired response was received."
"It has a good, high-level of storage."
"FAST auto-tiering is a great feature."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"Depending on how simple the customer needs it to be, might sway my recommendation one way or the other, but in terms of functionality, VNX is very very good."
"If you have a banking and finance domain, then go for EMC products as they offer better performance and scalability."
"It’s very stable in all the years I've worked with it, I know it’s stable and the support is there."
 

Cons

"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"It was not proactive communication."
"Some of the issues are that it's probably not on a par with other large storage enterprise type products."
"The data reduction that we had initially anticipated when we bought Pure and we moved over is way lower than the expected reduction."
"Storage. There could be better storage."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"The VNX reporting is much more granular, versus the Unity reporting."
"There are some limitations with the file storage."
"We did encounter a firmware bug which actually caused loss of data. There was some heartburn around that. But in general, it has operated as expected, except for that bug."
"I would give it a high nine out of 10. The only thing that makes me pull back is the continuing work on the support."
"There could always be improvements to the UI."
"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup."
"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise."
"I would like better monitoring capabilities: more historical data with more insight into the performance for the database."
"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."
"Customer Service: I don't like the way EMC's Powerlink support is behind a wall."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
"I think one area where we would like to see improvement is better deduplication and compression."
"We have had some scalability issues. Scalability options are limited due to the supported SSDs."
"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."
 

Pricing and Cost Advice

"We have seen a reduction in TCO."
"We feel that the pricing is fair and the licensing process was easy for both."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"The pricing is very attractive and it delivers performance for the money."
"We are finding the TCO of flash to be lower than SSD implementations."
"I don't know the exact cost but it's around $1,000."
"Pure Storage FlashArray is expensive."
"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."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity."
"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."
"This solution offers great pricing."
"We purchased a five-year warranty."
"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud. They have to protect their market by giving commercial or financial incentives."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"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."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"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."
"The initial pricing and licensing are reasonable. 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."
"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
"​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.
