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

"One valuable feature of the Pure Storage FlashArray is its Flash-based architecture, which provides a significant advantage."

"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."

"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."

"From the performance that I've seen, the simplicity of how to use it, the responsiveness, and customer experience, it is one of the best companies that I have worked with so far."

"The reliability is very good."

"The product has not gone down in a year, so I would say that it is stable, and we haven't seen any high spikes in read/write latency."

"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."

"Having an intuitive user interface to get things running is great."

More Everpure FlashArray pros

"The solution allows for easy, useful replication with good features for VPLEX and VIVO."

"We saved millions of dollars by not going back with Oracle."

"I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward."

"I like its performance and support."

"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."

"If you need to keep data safe and make sure it doesn't go anywhere, Dell EMC Unity is a good way to go."

"As far as cost is concerned, it does great deduplication, and from a storage perspective, we save money being able to dedupe right on the disk."

"We have resolved IT challenges with this solution; it sped up our environment, and we went from spinning disk to all-flash, which reduced our footprint."

More Dell Unity XT pros

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

"Reliability, excellent support by EMC, and VMware integration High availability including non-disruptive updates: We cannot afford downtime windows."

"If you are looking for a stable, powerful and effective entry level SAN that you can provision on your own for a small environment or a small office/remote office situation - this is definitely the product for you."

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

"One thing I would like to explicitly mention here is the EMC support; it is by far one of the best supports you will ever get in comparison with any vendor."

"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."

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

"I really value deduplication and compression to save space."

More VNX [EOL] pros

Cons

"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."

"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."

"I would like to see them lower the costs."

"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."

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

"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."

"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."

"The solution is expensive."

More Everpure FlashArray cons

"Support and licensing are big things, in the end, that needs improvement."

"The pricing is a bit high. We'd like it to come down."

"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."

"It needs more functionality and the ability to move across more landscapes."

"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."

"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."

"There is an issue with data duplication occurring on the flash memory. It should be improved. Timely updates and upgrades to the latest versions would be great."

"Dell EMC Unity is not sexy. It doesn't have all the flash and pizzazz of some of the other storage vendors."

More Dell Unity XT cons

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

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

"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."

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

"VNX can improve by offering flexible upgrade options."

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

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

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

More VNX [EOL] cons

Pricing and Cost Advice

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

"The cost has room for improvement."

"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."

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

"FlashArray is expensive, but the quality justifies the price."

"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."

"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."

"We purchased a license to use this solution and we pay for the storage ourselves."

More Everpure FlashArray pricing and cost advice

"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"

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

"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."

"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."

"This solution offers great pricing."

"It is priced at around or under $50,000."

"It is shipped with all licensed, included for this product range, no need to buy additional licenses"

"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."

More Dell Unity XT pricing and cost advice

"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."

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

"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."

"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."

"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.
