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

"Even if it costs a little bit more, you do get more for what you pay."

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

"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."

"I can personally state that the Pure Storage Flash Systems are the best built and Pure has the utmost professional customer care."

"For VMware, it has been a humongous savings."

"The most valuable feature of this solution is the support."

"It's easy to use, and the maintenance upgrades to get free controllers work really well."

"We have looked at all of the platforms, and to see what Pure was able to do within a PoC environment meant that we never turned back our PoC environment."

More Everpure FlashArray pros

"We have seen a huge performance increase due to all-flash that is beyond what was anticipated."

"For me, the most valuable feature is the ease of management."

"We expanded both our EMC Unity disks by 10TB without any disruption or issues."

"It is ease to use. It performs. It's easy to provision, and It's stable."

"The Snapshot feature is key."

"One of the things that I like the most about it is how they have changed the Unisphere GUI, and how it is now HTML5. It is so easy to use. Also, the array itself is so simple, easy to set up and easy to use, but it still has that great Dell EMC technology behind it."

"Once it is set up, it is definitely easy to manage."

"The most valuable feature is the ease of integrating it into our current environment."

More Dell Unity XT pros

"The most valuable feature is the auto-tiering, which helps in the speed of data access."

"Customer service is top-notch with a dedicated sales and technical resource who are familiar with your environment and spend a lot of time understanding your business needs."

"EMC storage has the best performance and functions."

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

"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."

"It would be a good choice for midrange businesses due to the performance/features and cost."

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

"It’s amazing, you can add and stack, and add more elements."

More VNX [EOL] pros

Cons

"It can go down from time to time, but it's been pretty solid so far."

"The number of Filesystems is limited, which it is not on the EMC VNX."

"Automation could be simplified."

"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."

"The solution is expensive."

"The price of the solution can improve."

"The product should improve its response time. I have also encountered issues with its configuration."

"It was a little costly."

More Everpure FlashArray cons

"One thing they could do is lower the price point."

"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. This would help us minimize our IT cost in terms of the backup procedures."

"They can certainly improve in terms of monitoring. The monitoring could be improved, and more features could be added."

"They're slow to implement new innovation with their product. EMC doesn't really innovate; they just sit there and wait for other people to innovate, and then they just copy."

"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."

"They should have more wizards for customers so they can do more of the self-service types of functions, in terms of upgrades and patching, although it's pretty easy right now."

"It is missing some features, like deduplication."

"Recently, they released products, sometimes without proper testing, it seems."

More Dell Unity XT cons

"EMC products are costly when compared to other vendors such HP, Hitachi, Dell, and NetApp."

"It is not the easiest product to implement and manage, especially on the NAS side, but that is now fixed in its successor product from Dell EMC called Unity."

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

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

"The CLI could be better documented, like with VMAX."

"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."

"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."

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

More VNX [EOL] cons

Pricing and Cost Advice

"I would prefer that they lower their pricing."

"There are no licensing fees or other costs."

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

"We are finding the TCO of flash to be lower than SSD implementations."

"You get what you pay for. It is expensive, but it really works."

"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."

"It is a more expensive solution, but it is worth it. You are getting what you paid for."

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

More Everpure FlashArray pricing and cost advice

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

"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."

"The price is very reasonable."

"It scales, but then you have to buy additional stuff."

"The pricing of Dell Unity XT is good."

"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."

"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."

"The solution should be cheaper."

More Dell Unity XT pricing and cost advice

"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"

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

"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."

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

"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 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.
