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

"It reduces space and the polar consumption. It also accelerates the application."

"It helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."

"The dashboard is nice. It is easy to manage compared to other storage solutions such as Dell EMC."

"It does everything they say it will do: It's very cost-effective compared to other big players, integrates very well with VMware, is tiny so we're saving power and space in the data center, and it's really easy for us to manage."

"It helps simplify storage. When you're running Pure all-flash, you don't have to do a lot of the old Oracle best practices. You don't have to worry about putting log files on a different disk channel than the data files, and those types of issues... That has made it vastly easier to do large volumes, rapid provisioning in databases, without taking a performance hit."

"It simplifies the overall management. We don't have to worry about storage anymore."

"Data deduplication features make it easier to manage storage and forecast growth."

"Their evergreen solution is probably the most needed in any industry, especially today in unprecedented times and supply chain issues, their evergreen solution is amazing."

More Everpure FlashArray pros

"Via a click, we can deploy a data store or LUN to the ESX host. We can also deploy VVOLs to the ESX server."

"We are happy with the way we have Dell EMC Unity XT configured."

"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example. It depends on you use it, but for our purposes, we find Unity simple to use."

"No issues with stability."

"It's a much smaller footprint than our older storage arrays, which take up some six tiles, a lot of space in the data center. The Unity's are a lot smaller, and they're a lot faster."

"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."

"The fact that it reduces our downtime gives us incredible cost savings."

"Since we have deployed, this has easily saved us close to about $300,000 easily."

More Dell Unity XT pros

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

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

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

"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."

"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."

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

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

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

More VNX [EOL] pros

Cons

"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."

"I would like FlashArray to add reports that help us forecast our predicted resource needs based on current usage."

"A noticeable area for improvement is the support for object storage. The FlashArray does not natively support object storage like S3 or Swift, which pushes customers needing these features towards the more expensive FlashBlade."

"I feel like there is too much automation; the user doesn't have any manual input."

"The GUI could improve, it could be more intuitive. There is hidden functionality."

"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."

"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."

"We ran into some issues with the program at first and we had to work around those issues to fix our problems."

More Everpure FlashArray cons

"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."

"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps."

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

"We integrated it with vSphere but that integration was "iffy". It was okay but we had a few challenges with it."

"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products. There could be better integrated and the capacity of the size could be larger."

"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."

"The price of Dell EMC Unity XT is higher compared to other solutions."

"I would like to see better compression, better dedupe. It's not nearly as good as what is built into the XtremIO. I understand why that is the case, but if they can take some of that technology and leverage that a little bit better in the Unity array, that would be great."

More Dell Unity XT cons

"There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore."

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

"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."

"Storage processor architect for real active/active HA ASIC based functions are needed"

"The migration process was very complex."

"As an entry level array, this is just right, but adding support for FAST-VP would be beneficial although that feature is available on the higher end VNXe3200."

"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."

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

More VNX [EOL] cons

Pricing and Cost Advice

"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."

"We feel that the pricing is fair and the licensing process was easy for both."

"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."

"Pricing is moderate. It is neither cheap nor expensive."

"The Evergreen Storage subscription is great, because then I get new controllers every three years."

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

"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."

"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."

More Everpure FlashArray pricing and cost advice

"It is an average priced solution."

"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."

"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."

"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."

"While Dell EMC is costly, I don't have any complaints about their licensing model."

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

"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."

"The solution should be cheaper."

More Dell Unity XT pricing and cost advice

"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."

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

"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."

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

"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."

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.
