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 is pretty much just plug and play. There is not that much to do with it. It is very easy to use."

"The stability is perfect. The reliability is 100% and the latency is always lower than 1 millisecond."

"We have seen savings in our storage. The speed of deployment has gone from several days to a few minutes. This product has reduced that time into minutes, simplifying storage for us."

"They are quite responsive and our local team was pretty good."

"The administration is very easy and quite minimal, the performance is very good, the installation is pretty straightforward, and technical support is good."

"Their REST API is wonderful, well-documented, and easy to use."

"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."

"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."

More Everpure FlashArray pros

"The product is easy to use and configure, and the support is also superb."

"It is completely reliable. The plugins for it are quite mature. I don't really have any issues with the interactions with vSphere, they all work as intended."

"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."

"We can get to our applications faster."

"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."

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

"It is scalable. Customers are going more into distributed architecture, so the Unity definitely has a scalable architecture built into that."

"I would definitely recommend Unity because, compared to VNX and other storage solutions, it is the easiest way to deploy for VMware and physical operating system services."

More Dell Unity XT pros

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

"Customer Service: It's great. Technical Support: It's great."

"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."

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

"It is a good product with a simple setup and easy administration."

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

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

"It’s very stable in all the years I've worked with it, I know it’s stable and the support is there."

More VNX [EOL] pros

Cons

"Larger capacity and more storage ports would be the two things I'd like to see."

"The time-to-market could be better at times, but I think that's true for all vendors of hardware."

"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."

"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client."

"There's always an opportunity for new feature functionality."

"We have not had a good experience with the IBM device."

"The integration capabilities could be improved."

"It would be beneficial to have a health check command that can be run from the CLI to ensure that all hardware components are functioning properly rather than having to enable remote access and connect to support for a health check."

More Everpure FlashArray cons

"I haven't seen the roadmap for this solution."

"In the dashboard there could be notification of duplicate files and the like, so we don't have to rely on Windows to do that."

"One of the issues we've had is that controllers have crashed several times. We've had a lot of problems with the storage processor, SPBs."

"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products."

"I think Dell EMC should be more careful in appointing partners, and they need to have better control over their partners. And if their partner has some problems with them, we should not suffer."

"They can certainly improve in terms of monitoring."

"They should update to the cloud."

"I would like to have secure mobile connectivity going forward. This would help me be more proactive."

More Dell Unity XT cons

"There were scalability issues, the scalability options are limited due to supported SSD."

"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."

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

"HP EVA and once NetApp, but they both had slow performance and a lack of features so we switched."

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

"With this product, the licensing software and capacity are very expensive."

"Make major changes to the file services, Celera, do something like a lite version."

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

More VNX [EOL] cons

Pricing and Cost Advice

"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."

"The solution is expensive."

"Because of the SSD, it is cheaper because I am not purchasing so many disks."

"It's expensive, but you get what you pay for."

"There are no fees for licensing. The hardware is paid for only once."

"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."

"We have seen a reduction in total cost of ownership."

"The cost was initially high, but once more people were using it, the costs came down. This was because the University was reselling it to other departments."

More Everpure FlashArray pricing and cost advice

"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."

"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.""

"The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."

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

"We purchased a five-year warranty."

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

"The solution is very expensive."

"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."

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."

"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."

"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."

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

"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.
