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

"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."

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

"The most valuable feature is how it simplifies the management of the SAN."

"The management features are well organized and they have a very good dashboard."

"I am satisfied with this solution, and we plan to keep using this solution."

"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."

"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."

"The performance of the storage is just unbelievable."

More Everpure FlashArray pros

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

"It is a stable solution that sells a lot...The deployment phase of the product was very easy."

"It is very user-friendly to read and determine the exact problem, unlike HP where different tools and L3 team support are needed."

"Technical support is very good."

"It is a hassle-free storage environment that helps us manage our hardware, the upgrades are helpful, and it makes our organization a more productive environment."

"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."

"The whole goal - high-availability, capacity, performance - all three were met by the Unity 450F storage platform."

"EMC is known for its reliability This product is good It is easy to install and maintain It operates with low maintenance and manpower costs"

More Dell Unity XT pros

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

"The stability of the hardware, and its ability to manage millions of IOPS, provides great comfort to system administrators, IT managers and CIOs."

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

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

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

"If you have a banking and finance domain, then go for EMC products as they offer better performance and scalability."

"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."

More VNX [EOL] pros

Cons

"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."

"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."

"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."

"I would not say anything because we still do not use Everpure FlashArray fully."

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

"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."

"Price is about the only thing that's wrong with it."

"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."

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."

"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."

"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."

"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."

"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."

"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."

"In terms of what could be improved, I would say its capacity and its connection."

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

More Dell Unity XT cons

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

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

"We have had some scalability issues. Scalability options are limited due to the supported SSDs."

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

"Oracle is never the cheaper solution. Compared to others, it is always among the most expensive."

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

"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."

"You need a lot of licenses in order to use this product, which makes the product expensive; the maintenance contract price also increases significantly every year."

More VNX [EOL] cons

Pricing and Cost Advice

"Price is about the only thing that's wrong with it. A little bit better pricing would be great."

"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."

"It is a cheaper solution."

"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."

"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."

"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."

"It is light years beyond anything else with the same price point."

"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."

More Everpure FlashArray pricing and cost advice

"Pricing for this product is manageable, though slightly higher than comparable products."

"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."

"We have to apply for a license for each system."

"We purchased a five-year warranty."

"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."

"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."

"This solution offers great pricing."

"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."

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."

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

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

"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."

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.
