Technical Lead at Wipro Limited

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

"Overall, I am sure that Everpure FlashArray is the best option on the market."

"Pure Storage FlashArray is a good product with minimal management requirements once set up correctly and helped reduce our storage footprint from EMC."

"The technical support from Pure Storage FlashArray is perfect; if we have some trouble or we need to change something, we ask for support and they are helpful and answer immediately."

"Pure Storage FlashArray provides immediate benefits to our customers with its easy setup process, allowing for instant use and rapid realization of advantages."

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

"The stability and performance are the best things about the solution."

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

"We also like the compactness, the small footprint. It takes up very little space in a data center and uses little power."

More Everpure FlashArray pros

"There's some new stuff coming with 7.3, which just got released, where they're spreading the sparing across the whole array, rather than having a dedicated spare disk, and have it sit there and do nothing until one of them dies, and then it kicks in - and having to rebuild all of that. Now, they'll do the sparing across all the disks and they say that is going to add not only space but performance to the array, with 7.3."

"The Phone Home support is very good, providing proactive troubleshooting and responding quickly, and we also have a local vendor who supports all our IT infrastructure and acts as our consultant."

"With mixed workloads, we are seeing at least a 15 to 20 percent improvement."

"They have a feature called Live Migrate; it's been very, very useful."

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

"The solution is stable."

"It is fast and performs well."

"The most valuable feature is the speed for the end-user."

More Dell SC Series pros

"Latency is definitely the big key for us."

"Rocketing IOPS results in performance we don't have to fixate on, so we can instead focus efforts on other layers in the stack, knowing that our SAN layer is lightning fast, with capacity to spare."

"Our holdup was disk I/O, so we did a PoC with Kaminario and we reduced build times down to fifteen minutes for a full build from two hours."

"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."

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

"The stability of the solution is very good."

"From my perspective, it is a huge success fulfilling everything we needed and more!"

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

More Kaminario K2 [EOL] pros

Cons

"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."

"The only thing I think could be improved is price. The price is the main concern for our customers."

"The solution is not cheap."

"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."

"The scalability of the solution is not as good as it probably could be."

"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."

"Once, before Pure went public, we were a member of their customer advisory board and beta tested replication. One requested enhancement yet to manifest is the scheduling of snapshot replications."

"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

"They need to make it a little cheaper."

"Matching color coding during zoning is sometimes a little bit annoying."

"The only issue with scaling up is that the pricing gets pretty high."

"For example, for a 4TB SSD, they may charge you seven grand or eight grand. It's expensive."

"The configuration could be easier in Dell EMC SC Series."

"Overall, I'd like to see more synergy between Dell EMC's higher-tier platforms and their mid-tier platforms. What I have said, constantly, to my partners at Dell EMC is that the clear articulation of the path is really important to us. In that vein, what I'd also like to see is, with the migration strategy that's built into this product, a lot more attention paid to Dell's - in particular - legacy platforms and how we get from some of our legacy EMC platforms onto this platform with a straight-through migration and scaling strategy, not host-based migrations and not piecemeal... Dell EMC would do well to focus more on my ability to skip a generation, rather than having me take individual hops because I can't greenfield my way into a software-defined data center fast enough. This journey of multiple hops is not helpful."

"We had some issues with the battery in the previous version that we were unable to resolve."

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

More Dell SC Series cons

"The interface look and feel could be improved."

"The management graphical interface needs more improvement."

"Replication and de-duplication could be better."

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

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

"I'd give it a perfect rating if I could push it to 300,000 IOPS like they promote; we just haven't been able to push that many IOPS out of our system."

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

"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."

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."

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

"The cost was initially high, but once more people were using it, the costs came down. This was because the University was reselling it to other departments."

"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."

"We have seen a reduction in total cost of ownership (TCO)."

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

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

"Our costs are around $100,000."

More Everpure FlashArray pricing and cost advice

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

"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."

"The pricing of Dell EMC Compellent is competitive."

"It is one of the most cost effective systems for us. We have been able to run it longer than most, getting the most benefit and money out of it."

"Always keep in mind, this is not just a enclosure with disks is a complete SAN as a service. There is software, license, and storage in one single solution."

"This product is too expensive compared to others, and I don't see any value in using it."

"We have found the solution to be affordable."

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

More Dell SC Series pricing and cost advice

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

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

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

"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."

"The licensing is all-inclusive."

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