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

"The snapshot feature is valuable. It protects data based on the policy."

"It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."

"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."

"The seamless integration into the public cloud has improved my organization."

"For me, right now, it is the best storage solution in the market, by far."

"Our clients see a reduction in total cost of ownership by around 40%."

"We also use VMware integrations developed by Pure, their plugins in our vCenter environment. They help by allowing our non-technical operations teams to deploy new data stores and resize data stores without me having to involve myself all the time to do those simple tasks."

"We chose Pure Storage because it had the best performance of all the products that we tested."

More Everpure FlashArray pros

"We're using Dell EMC Unity as our primary storage for our production and for our DR site, we've had no performance issues with it whatsoever and we're using it for everything."

"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."

"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example. It depends on you use it, but for our purposes, we find Unity simple to use."

"The valuable features of Unity include that it's flexible, has a friendly user-interface, and provides good performance."

"Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space."

"You can add volume and it's automatically registered in VMware."

"It will certainly help us scale bigger."

"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."

More Dell Unity XT pros

"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."

"Technical support is fast and always fixes the issues."

"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."

"It has a good, high-level of storage."

"We moved from CX with FC/SATA to VNX with SSD, SAS, NL-SAS and using SSD as Fast Cache we have seen huge performance gains in certain operations."

"Integration with VMware"

"The VNX 5700 provides a large number of features including the ability to work for both file and block as a unified array."

"Good performance for VM environments"

More VNX [EOL] pros

Cons

"A noticeable area for improvement is the support for object storage."

"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."

"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."

"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room."

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

"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."

"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."

"I would recommend improvements in the graphical user interface, specifically a detailed hardware view that would allow us to see the individual drives and individual controllers more easily, as currently, they are presenting only a higher-level view."

More Everpure FlashArray cons

"I miss storage groups. Now, if I have to add a LUN to a cluster, multiple host, I have to know which host is in that cluster. I have to write it down and that makes it hard. In VNX and earlier, I could simply put a LUN on a storage group and every host in the group had the LUN. This lack bothers me a lot because it takes a lot of time and mistakes are made. Sometimes, a Hyper-V host gets a VMware LUN and vice-versa. Not good."

"The price has room for improvement."

"This solution would be improved with the addition of flexible raid volumes."

"Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product."

"Problems with I/O modules, with bugs that came out that really should have been caught before the product was released."

"One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX."

"We went to the PowerMax because of the needs that we have for the business. We're doing true enterprise-level storage. So we went from Unity to PowerMax to give us that tier that we were looking for."

"It is missing some features, like deduplication."

More Dell Unity XT cons

"They don’t quite provide enough security in the data centre."

"If the VNX had embedded encryption, that would be great."

"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."

"So far we haven't had many issues with the VNX. However, the Data Mover (that manages CIFS/NFS) part needs some improvements."

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

"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."

"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."

"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."

More VNX [EOL] cons

Pricing and Cost Advice

"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."

"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."

"Its price is almost double than any other flash storage solution."

"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."

"Pure Storage FlashArray is expensive."

"The best features come included without any additional cost."

"The price was more favorable than Dell EMC."

"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."

More Everpure FlashArray pricing and cost advice

"This solution is a good price for what you get."

"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."

"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."

"It is a good return on investment."

"From a pricing perspective, this solution is comparable to others on the market."

"Most licenses for the solution are free but upgrades are available when adding additional software or storage."

"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."

"This product is cheaper than the EMC VNX solution. It is good for small businesses."

More Dell Unity XT pricing and cost advice

"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."

"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."

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

"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."

"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"

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.
