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.

Storage solutions accommodate diverse drives and offers good resiliency

Technical support is good. I can log complaints online through the portal and have engineers in line. I can also take dedicated engineers if needed, although this involves a different support cost. As far as my requirements are concerned, it is working fine. There are two or three types of support. Standard support involves logging a complaint and receiving a call from the OEM on the same day, but hardware replacement takes two to three days. Advanced support offers instant replacement without delays. Hardware support terms include calling or emailing the company or logging the call in the portal to receive remote support, or getting a dedicated engineer or account manager from Dell.

A solution with a simple configuration and good stability but it's quite expensive

Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"This solution has helped my organization by cutting down on provisioning time. I used to have to provision a VM and it would take ten minutes. Now, it takes thirty seconds."

"When we needed to replace the other arrays, we went straight to Pure and life-cycled them into Pure in every segment we have."

"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."

"Now with Pure Storage, our developers work a lot faster and more efficiently which has definitely improved our productivity."

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

"It worked flawlessly."

"The most valuable feature is that maintenance is free."

"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."

More Everpure FlashArray pros

"One time, we had a drive fail and we were notified before we even saw it on the device."

"It's allowed us to have one hundred percent uptime over the last five years — maybe more."

"With the SC Series SAN, the performance that we've gotten out of the boxes alleviated anyone's concerns."

"I've found the stability to be very good."

"It was very easy to install, maintain, and provides excellent manageability."

"It has a good price point and offers some value-added enterprise features."

"I can mix and match the drives, using older mechanical devices and the latest SFP drives in a single solution with different enclosures."

"The most valuable feature is the customer support."

More Dell SC Series pros

"Image backups of our production servers that used to take hours now take minutes."

"Ease of use: My installers - my administrators over the system - they love how easy and fast it is to install and spin up a LUN and get going."

"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."

"The speed and, for us in particular in what we're doing, the data de-duplication."

"The stability of the solution is very good."

"It has a very good duplication rate; very, very good."

"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."

"I think this product hits all the big features of all the SANs that are out there, all the storage vendors that are out there and more."

More Kaminario K2 [EOL] pros

Cons

"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."

"I would appreciate improvements on daily health checks."

"It is not possible to create a cluster on top of multiple arrays."

"If there is one thing that I did not appreciate about Pure, it is that between the two different lines, which would be FlashBlade and Everpure FlashArray, there is no easy way to migrate LUNs as far as being able to replicate across those platforms."

"I would love to see a true one click upgrade solution."

"The product could improve by providing the capability to support NAS storage – CIFS and NFS."

"We would always like to see higher performance, and lower pricing is always better."

"Many high-end platforms from other vendors like Dell EMC or Hitachi, their backend has Active/Active architecture, unlike Pure Storage FlashArray which doesn't utilize an Active/Active architecture on the backend."

More Everpure FlashArray cons

"There's always room for improvement in the operating code."

"The lower model, the 3000, should have duplication. It doesn't right now. It's only from 5000 that this is offered, but it depends on the performance. It could be they don't offer it on lower models because the duplication is too much of a burden to the performance."

"The interface could be improved. It should have an application point of view."

"The ease of use could be improved. It took me a while to learn it."

"I would like to have 100% functionality through the web app."

"Licensing, especially on the storage line, could use some simplification. It's not terrible, but, for example, with the Isilon series, they've gone to completely a la carte. A la carte is very difficult to traverse, as to what you need. It would be more beneficial, at least from my point of view as a customer, if they did it more like car companies do, where there are package lines"

"Compared to other solutions out there, it's affordable. It would be nice if the cost was even lower."

"It would be helpful if the solution offered higher performance, at least on the back end."

More Dell SC Series cons

"There are some mid-market SMB customers that it may not fit the best for from a pricing perspective, but for the vast majority of our customers, once we aware of it and learned about the technology which it performed with, it fits a very useful metric."

"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."

"The front panel of the drive shelf doesn't always seat firmly."

"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."

"A single pane of glass to monitor/manage multiple arrays would be helpful."

"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."

"I would like them to come down in price."

"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

"All storage is expensive so any price improvement would help."

"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."

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

"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."

"We have an Evergreen Storage subscription, which I think is a great feature."

"The pricing is very attractive and it delivers performance for the money."

"It's priced higher than the market."

"The price of Pure Storage FlashArray is expensive."

More Everpure FlashArray pricing and cost advice

"The pricing is reasonable, but it is expensive."

"We have reviewed many platforms over the years. It is probably the best solution for its value."

"We have found it to be affordable. Comparing the cost with other hardware, it seems to be right in line with the compute and the storage that we get with it."

"It has a good price point and offers some value-added enterprise features."

"Pricing depends on varying life cycles."

"It's absolutely affordable. Again, not having to do a forklift upgrade like some of the others have had to do in the past, it's very affordable for our customers and they continue to buy."

"The scalability seems a bit more expensive than even buying a brand new one so far. That has been kind of a drawback."

"There are costs involving the solution, vendor fees and product safety which are additional."

More Dell SC Series pricing and cost advice

"Kaminario is very competitive on price. They also have a pay per TB model."

"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."

"The licensing is all-inclusive."

"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."

"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."

"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."

"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
