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

"The features that are there now are really what we need."

"The solution has great efficiencies because it has scalability."

"Even if it costs a little bit more, you do get more for what you pay."

"It worked flawlessly."

"The biggest lesson that I have learned from using Pure FlashArray is that it's user-friendly, easy to manage, and very flexible."

"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."

"As we needed to grow in capacity, we were able to do so without increasing footprint by replacing smaller devices with larger ones."

"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."

More Everpure FlashArray pros

"No issues with stability."

"Unity is very stable."

"Delivers High IOPS, but more important, low latency as this is the most important part for our usage."

"Pricing is relatively good compared to other vendors with the same specifications."

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

"The most valuable feature is the fast cache with functionality rewrite."

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

"Moving also from a hybrid to an all-flash array helped us to minimize footprints in our data centers."

More Dell Unity XT pros

"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."

"EMC storage has the best performance and functions."

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

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

"One of the best features of the VNX is the ability to combine drives of different types into a virtual Storage Pool. By combining small but fast flash drives, SAS drives, and high-capacity but slower NL-SAS drives, the VNX can intelligently move data to the different tiers of storage based on usage."

"I have worked on CLARiiON and all series of VNX."

"The replicating of the entire storage unit to a different location was a very useful function."

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

More VNX [EOL] pros

Cons

"Regarding documentation, it would be helpful if we could have access to the root passwords for administrative tasks."

"In the next release, I would like to see file-level encryption."

"The scalability of the solution is extremely costly."

"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."

"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."

"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. We want to be able to read through the encryption."

"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."

"It was a little costly."

More Everpure FlashArray cons

"The price of this product can be more cost-effective."

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

"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."

"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful."

"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside."

"The application's administration needs improvement and become better."

"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."

"The support team is well-versed in the AMG solution, having received comprehensive training. They also boast strong partnerships in both VNAM and Korea. The system's user-friendliness is a primary consideration in their choice of solution, emphasizing the importance of service. They place a strong emphasis on service, occasionally requiring approvals. However, with full installations, they have achieved almost uniformity. Their storage approach differs from a consolidated business-based model; instead, it is application-centric. Their investment in solutions is geared towards specific needs, such as the banking or information system, acquiring smaller storage units individually."

More Dell Unity XT cons

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

"VNX can improve by offering flexible upgrade options."

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

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

"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."

"EMC pricing is too expensive, like the Apple brand iPhone in the cellphone market."

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

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

More VNX [EOL] cons

Pricing and Cost Advice

"It is a more expensive solution, but it is worth it. You are getting what you paid for."

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

"The pricing is reasonable."

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

"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."

"We lost a lot of customers because we couldn't compete on price with other vendors."

"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."

"It is a cheaper solution."

More Everpure FlashArray pricing and cost advice

"The ROI is right where we need it to be. It's a reasonably priced array."

"The solution should be cheaper."

"Go with the virtual appliance versus the hardware."

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

"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."

"The solution is extremely functional for the price that we pay for it. It is worth the investment."

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

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

More Dell Unity XT pricing and cost advice

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

"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."

"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."

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.
