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

"This is the best all-flash storage array on the market."
"Processes that used to take 40 minutes to two hours can be completed in five minutes."
"The administration is very easy and quite minimal, the performance is very good, the installation is pretty straightforward, and technical support is good."
"The pricing of the product is very competitive to others in the market for Flash and NVMe storage, and from an ROI standpoint, if you consider compression and de-duplication and all that, you get a pretty good ratio."
"Everpure FlashArray is probably not cheap storage, but it provides great performance, scalability, and everything a customer needs."
"Before we used Pure Storage it took 93 days of employees who run the database to back up and restore databases. The scale of deployment basically went from several days to a few minutes."
"From an investment standpoint, the support staff I require for it is greatly reduced, so I don't have the in-depth requirements that I had on other products."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"It is stable, I have not personally seen any issues when deploying in a customer environment."
"All-flash is a game changer. If you need performance, simple operations, and you plan to use it with VMware, it is a good choice."
"We did a thorough evaluation of other solutions and it was clear after the performance evaluation, Dell EMC Unity XT was the best choice."
"It is easy to manage. A lot of the system manages itself."
"We have had no stability issues with the product, including when adding replication on the fly, customer installed code updates, and customer installed DAEs."
"There are also DR and data protection functions that we found in the new Unity, now that we are stepping up from VNX and other storage appliances, that we've started implementing."
"Storage Snapshots have been really nice. They allow us to do backups without impacting our production workload that much. The scalability, the ability to add disks dynamically and adjust our workload as needed, has also been really helpful. That definitely makes my job easier. And the interface for managing Unity is very easy. The integrations between VMware Hypervisor and Dell EMC are top-notch, so it's been really easy to use and manage."
"We saved money by moving off old storage and we gained extra capacity and speed."
"Good performance for VM environments"
"I really value deduplication and compression to save space."
"It is very stable even during multiple power failures."
"EMC storage has the best performance and functions."
"The replication feature provides another functionality to protect your data."
"Technical support is good."
"It has a good, high-level of storage."
"Stability has been rock solid, as we have been running both units for over two years with no major problems."
 

Cons

"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"There are a lot of things to improve."
"The price should be lower."
"The system has dual controllers but does not have a high level of resiliency built-in."
"In Pure Storage FlashArray, the area with room for improvement is local MFA login."
"The price could be better."
"They should work on their upgrades, they're not smooth."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM."
"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."
"It could always use native replication. Then I could get rid of RecoverPoint."
"Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature."
"Things that could be improved include one-to-many replication, data deduplication, and asynchronous Fibre Channel replication. It is asynchronous on iSCSI and I would like to have that on the Fibre Channel. Unisphere-wise, I have to log in to each Unity as a unique environment. In VNX, I logged in to the domain and I was logged in to every VNX. So that's missing."
"One thing they could do is lower the price point."
"The storage processors have less port expansion than previous high-end VNX arrays. Data compression is only available in all-flash pools."
"Compression and block deduplication on non-all-flash solutions."
"The migration process was very complex."
"We encountered scalability as it is limited by backend slots, and NAS performance is significantly reduced when scaling."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"They don’t quite provide enough security in the data centre."
"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."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"We have had some scalability issues. Scalability options are limited due to the supported SSDs."
"You need a lot of licenses in order to use this product, which makes the product expensive; the maintenance contract price also increases significantly every year."
 

Pricing and Cost Advice

"We feel that the pricing is fair and the licensing process was easy for both."
"The price of the solution can be a bit expensive. There is an additional fee for support."
"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"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."
"Pure Storage has not helped to reduce our HANA licensing costs."
"Pricing is moderate. It is neither cheap nor expensive."
"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."
"At the end of the day, the licensing cost is key, because every customer has a pain point, that the cost of each piece is high. So if they would bundle everything in a package, that is how the competitors are selling their footprint."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"Go with the virtual appliance versus the hardware."
"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."
"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. Yearly EMC is more expensive."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"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, the yearly EMC is more expensive"
"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."

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.
