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.

Replication and dashboard improve system integration efficiency

It's a good product, but the implementation with the new systems is done via the cloud dashboard from HPE. I can't activate the system without a cloud connection, which is a bit laggy if I don't have the right firewall settings, making it take longer to implement the storage. It was better with the old systems, where I could install and activate without cloud connectivity.

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

"One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."

"We put a fair amount of stress on it because we run sequel workloads and we run web applications where the same web files are hit over and over, and we have had almost zero stability issues with that SAN, which has been really great for us."

"Pure Storage FlashArray has helped us to improve the reporting and the billing cycle."

"This solution has improved my organization because it has good performance."

"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."

"The white glove customer service that I get is their greatest value."

"We clearly have seen the difference between having storage on Dell EMC or NetApp versus what we have now on Pure Storage, and the investment was a clear win for us."

"The most valuable feature of the Pure Storage Flash Array is the blazing fast monitoring."

More Everpure FlashArray pros

"The initial setup is straightforward."

"It has totally taken away a layer of time and effort, management-wise, from two engineers to give that time back into developing more solutions. It has provided us essentially with a platform to go away and be more creative, knowing that that is stable and can do whatever we chuck at it."

"The support is very good at being proactive in helping us resolve issues and they have been better than most other competitors in this area."

"It has vastly improved the responsiveness of our servers."

"This product is very easy to set up, and the design of the hardware and software lends itself to great performance and redundancy."

"HPE Nimble Storage has a simple management end-user."

"The performance and simplicity are the most valuable features."

"If you're currently looking for a new storage solution in your environment, give Nimble Storage a chance."

More HPE Nimble Storage pros

"The GUI is very straightforward and easy to use."

"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."

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

"Kaminario allowed us a solid state solution with marginal incremental cost."

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

"Improved performance by more than 50x on our application."

"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."

"It is consistently stable; haven't had a single issue with it."

More Kaminario K2 [EOL] pros

Cons

"It was not proactive communication."

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

"Everpure FlashArray can be improved as the pricing is expensive, but you do get what you pay for; you are paying a premium for better service, better warranties, less downtime, and other things, so I do not know that a lower price would work out because you probably would not have that high of quality for those things."

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

"I would like to see them lower the costs."

"I would appreciate improvements on daily health checks."

"I would like to see box-to-box encryption on replication included in the next release."

"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."

More Everpure FlashArray cons

"We heard from the Nimble pre-sales in 2015 that an inline deduplication feature is forthcoming (2016). What I know now is that this is not the case, dedup is only for all-flash array only, something to do with computational constraint."

"I want to see the full integration with OneView."

"The cost of this storage solution should be lower."

"The amount of firmware updates released seem excessive."

"So far, the only area I have noticed that requires improvement is the ability to console directly to the device."

"I want it to be an active-active array. Nimble would be great as an active-active array because then everything checks out. It would give a feeling of comfort."

"There is a new version of the Nimble and 3PAR systems called Alletra and they have a lot of new features."

"Just continue the updates of technology features; I expect there will be more updates in capacity and IOPS as models upgrade in the future."

More HPE Nimble Storage cons

"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."

"On the road map, I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."

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

"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."

"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 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."

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

"There are a few areas where the system could be improved. Examples would be that the system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

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

"There are no licensing fees or other costs."

"There is an annual or perpetual license required for this solution."

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

"It's a good price point and it's a solid product for the price."

"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."

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

"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."

More Everpure FlashArray pricing and cost advice

"Performance per dollar, when we looked at it, was the highest that we could get for what we needed."

"HPE Nimble Storage is more expensive than some of the other solutions, such as Pure Storage. They charge more for every feature than other vendors."

"There is a monthly fee to use the solution."

"The pricing is expensive, although we do not pay anything in addition to the standard licensing fees."

"We are paying for the licensing yearly."

"It is a CAPEX investment. Over the anticipated lifespan, I would say the pricing is $10,000 a month."

"If you are a super small company, the product is probably not right for you. It is out of your price range. Anything from mid-SMB up to enterprise, it is absolutely the right product."

"I believe the array, maintenance, and everything totaled around $140,000 dollars."

More HPE Nimble Storage pricing and cost advice

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

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

"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."

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

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

"The licensing is all-inclusive."
