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

"Once it's set up, it just runs on its own and only requires the occasional checkup."

"Our storage phones home. It is smart and intelligent in that aspect, which has been huge for us. We don't have to be storage administrators."

"After moving to Pure Storage, I have noticed that our databases are considerably faster and our performance has improved by at least four times."

"This storage has to be the most well thought out and effective storage that I have had the privilege to work with."

"We have integrated the solution with VMware, and the process was seamless."

"The most valuable features are the ease of use and support."

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

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

More Everpure FlashArray pros

"We can sleep at night because the support is great."

"It has saved us time when provisioning new storage, so we're trying to automate that process."

"It is completely reliable, the plugins for it are quite mature, and I don't really have any issues with the interactions with vSphere, they all work as intended."

"The solution overall has high performance."

"We have adopted the all-flash array; it eliminates all the overhead of tiering and a lot of the data structuring overhead involved, and it gives us a lot of operational efficiencies."

"We use it to implement all our VDI solutions."

"All-flash is a game changer. If you need performance, simple operations, and you plan to use it with VMware, it is a good choice."

"All-flash performance, snapshotting capabilities, and replication are all valuable features."

More Dell Unity XT pros

"In a banking environment, on which we required a very high throughput for our database, we have used this product and our desired response was received."

"It is very stable, even during multiple power failures."

"It is a great product: scalable, reliable, and robust."

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

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

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

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

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

More VNX [EOL] pros

Cons

"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."

"The time-to-market could be better at times, but I think that's true for all vendors of hardware."

"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 integration capabilities could be improved."

"I would like to see them develop the ability to integrate with more AWS services. There are increasingly more and more services coming out from AWS but there are also certain constraints where we can't move everything over to a cloud as well. We would like for things that are on-premise to be easily integrated with AWS."

"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."

"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."

"In some cases, we get into very in-depth conversations around the movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."

More Everpure FlashArray cons

"We would like to see the synchronous replication process included in the next release. Not having this downgraded our performance by 65 percent."

"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."

"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."

"The pricing is a bit higher than expected, and this is an area where I see room for improvement."

"To the best of my knowledge, migration from VNX to Unity without VPLEX/RecoverPoint is not available right now."

"The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult. They should improve this to have a better reporting system."

"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."

"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."

More Dell Unity XT cons

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

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

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

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

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

"EMC wasn't able to fix the issue, so they had to stop using snapshots."

"I do not recommend the Gen 1 VNX to anyone in this day and age."

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

More VNX [EOL] cons

Pricing and Cost Advice

"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."

"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."

"Pure Storage FlashArray is expensive."

"The price was more favorable than Dell EMC."

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

"Pure Storage has not helped us to reduce our licensing costs."

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

"The price is reasonable."

More Everpure FlashArray pricing and cost advice

"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."

"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."

"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."

"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."

"The price is very reasonable."

"The product’s pricing should be improved."

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

"This solution offers great pricing."

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."

"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."

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

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

"The initial pricing and licensing are reasonable, the 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.
