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.

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

"I cannot imagine my workflow without Everpure FlashArray because I do not have any other type of storage in use."

"Everpure FlashArray is very good with AI development and is very suitable for low downtime and critical mission storage, so customers who need critical mission storage and those chasing performance should consider this solution."

"Biggest lesson learned: Why didn't I switch sooner?"

"They have a very good support system, and the GUI is also very intuitive."

"For an organization, it can take storage from 40 terabytes down to five terabytes."

"My favorite feature about Pure Storage FlashArray is definitely the simplicity; in one word, it's simple to install, simple to upgrade, simple to maintain, and simple to manage."

"Very stable; no worries about how much it can handle."

"Everpure FlashArray is probably not cheap storage, but it provides great performance, scalability, and everything a customer needs."

More Everpure FlashArray pros

"This is a great storage solution and a product that I recommend."

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

"It hasn't missed a beat; we haven't had any issues with it whatsoever, speed has been great, it does everything we need, there has been no downtime, and with built-in redundancy upon redundancy I feel very confident with it."

"Dell EMC Unity XT has good integration with VMware."

"It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy."

"As far as benefits, Dell EMC Unity XT gives us fast access orders for everybody in accounting, and it's working."

"The Dell EMC Unity is a small but powerful storage solution."

"It's easy to handle for administrators and it's a unified system."

More Dell Unity XT pros

"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."

"VNX 5200 works well with a medium VMware cluster, has good performance, and enables hardware disk replication."

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

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

"Integration with VMware"

"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."

"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."

"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."

More VNX [EOL] pros

Cons

"Based on my experience with various technologies like EMC, NetApp, and Pure Storage, one area for improvement is compliance certifications. NetApp excels in this area, particularly in the American Army or defense sector, where NetApp has approval, whereas others are striving to achieve the same. NetApp also delivers security, ransomware protection, and scale-up capabilities more effectively."

"Organizations with security concerns that prevent cloud utilization would benefit from a wider range of instruments available for offline operation. Currently, the limited selection of on-premise instruments hinders Pure Storage FlashArray's ability to compete effectively with other vendors."

"I would love for them to have a hyper-converged solution."

"I think replication is one area that still needs improvement."

"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."

"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."

"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."

"Pricing could be better in comparison to other solutions."

More Everpure FlashArray cons

"Support Responsiveness & time to fix bugs should be improved."

"We cannot connect directly with Dell due to sanctions."

"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."

"I would like better monitoring capabilities: more historical data with more insight into the performance for the database. We now use a separate tool for it. Therefore, it would be nice if we could have that straight from the tool."

"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."

"If I can connect to my Unity through my iPad or my cellphone to check everything is okay and view the information via a dashboard, I would like to have secure mobile connectivity going forward."

"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."

"We realized that we were barely getting a 12 percent compression offset, not the 50 percent, and this came about the time of the merger."

More Dell Unity XT cons

"Due to very complex structure and sophisticated architecture, it needs experts for trivial troubleshooting also."

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

"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."

"It only supports 10Gb copper, and cannot do 10Gb fiber."

"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."

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

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

"Yes, we have had issues. The system is limited by the number of enclosures."

More VNX [EOL] cons

Pricing and Cost Advice

"I would rate it a seven out of ten for pricing. It could be improved."

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

"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."

"Pure Storage FlashArray's pricing is very competitive."

"The price, in general, is around $100,000, however, I know it costs more."

"The price of the solution can be a bit expensive. There is an additional fee for support."

"There is always room for negotiation."

"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."

More Everpure FlashArray pricing and cost advice

"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."

"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."

"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise. Huawei and Lenovo are very price competitive. Looking at the price point for a country like Sri Lanka, where we have a very low economy, I think you need to look at a pricing mechanism that is a bit more flexible."

"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."

"Licensing is fine. We worked with a sales rep to purchase our Unity."

"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."

"I rate Dell Unity XT’s pricing a nine out of ten."

"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."

More Dell Unity XT pricing and cost advice

"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."

"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."

"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. Yearly EMC is more expensive."

"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."

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.
