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.

Good customer service and support and suitable for large environments
It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Automation simplifies storage management and enhances operational efficiency
The features of HPE Alletra Storage that I appreciate the most are the ease of management via CLI, as we have written many homegrown scripts that access the CLI to automate our processes to either increase storage, create snapshots, and refresh snapshots. The whole process can be done through automation. HPE Alletra Storage enables me to get assistance from senior support engineers without having to go through support escalations, and that's actually part of the whole GreenLake system. When we have issues, it's excellent. The engineers have come in to analyze our cases and helped us get through our issues. HPE Alletra Storage has helped reduce our data management operation expenses. Back in the day, CapEx was always the hard thing to do, and by going through GreenLake, we were able to convert that CapEx expense of buying storage to an OpEx by going with the GreenLake rental of the HPE Alletra. It's reduced data management costs. It's hard to say by how much. We've been with HP for years. GreenLake has reduced the time spent on capacity planning. We're charged on usage, and there's more storage than what we need. We don't have to do a five-year plan or stress about running out of space. We only pay the minimal amount or for what we use. We use seven development database QA and development databases based on snapshots of our production We refresh every about four to six weeks, each of those databases. And that's all done through automation that we've created. It has greatly reduced our need for additional storage space, however, they are allowing us to do the dev and QA on snapshots. The solution provides a cloud-like management platform, although we don't necessarily use it that way.

Quotes from Members

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

Pros

"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"It’s easy to set up and support is excellent."
"The pricing of Pure Storage is all-inclusive; it is very fair, very easy, and the solution is a lot easier to install than the Dell EMC product."
"The initial setup is very straightforward. You simply plug it in and turn it on."
"Support has been helpful."
"Performance is the most valuable feature."
"After switching to Everpure FlashArray, we saw significant results, as whatever hardware we used before is now compressed to 80%, maximizing space utilization in a single system."
"The all-flash disc is the most valuable feature of this solution."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."
"We have been able to realize storage space savings for our virtualization environment and it has reduced our electricity usage by reducing the number of disks needed for the virtual environment."
"High performance and ease-of-management are the most valuable features."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"With so much technological advancement and more coming, the world is their oyster."
"After five years, the cost decreases over 30% and the performance increases over 50%."
"It performed great originally, and when it performed great, it was awesome."
"Alletra has helped reduce the time spent resolving storage-related support tickets by about 40%."
"Using HPE Alletra Storage has improved the performance of my storage and alleviated a bottleneck."
"The most valuable feature is the integration with vCenter with the HPE multi-storage plugin. That makes it more comfortable to use the storage with just a few clicks."
"HPE Alletra Storage's capacity efficiency is notable due to the data reduction we get from it."
"My experience with the deployment of HPE Alletra Storage has been good. I like the single pane of glass approach."
"There is ease of use for junior admins. We have VMware integrations for data stores, cloning operations of existing data stores, and InfoSight analytics."
"We have the most advanced HPE products available that we can monitor with the HP InfoSight feature, which enables us to check every metric, including bandwidth and latency, at a granular level. Alletra's mechanism is excellent and can handle multiple traffic sources. Anything is possible. Regarding your application, the IO behavior can be random, sequential, or a database. It serves web and e-commerce applications better."
"The features of the HPE Alletra Storage benefit my organization by providing space saving through dedupe."
 

Cons

"They should work on their upgrades, they're not smooth."
"There are many features which need to be added, particularly on the replication side."
"Based on my experience with various technologies like EMC, NetApp, and Pure Storage, one area for improvement is compliance certifications. NetApp excels in this area, particularly in the American Army or defense sector, where NetApp has approval, whereas others are striving to achieve the same. NetApp also delivers security, ransomware protection, and scale-up capabilities more effectively."
"The only minor issues that come to mind are that, every once in a while, a hard drive will go bad. Also, the solution should be cheaper."
"It needs to improve its price."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"In future releases, I look forward to more AI features."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"Snapshots are not as easy to access as on a NetApp device."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."
"It's annoying that if you turn on SMB3 (as opposed to the earlier CIFS protocol), then it is not possible to access a file store using a mixture of SMB and NFS."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"I would say that HPE Alletra Storage has not reduced my data management operation expenses at this time, because we aren't probably leveraging it as much as we could."
"The best way forward is to continue keeping the product lines within the Alletra brand specialized to what makes them good, ensuring that the features from where 3PAR was good, Nimble was good, and Apollo was good are maintained so that customers who have relied on them can continue to count on their availability."
"I'd like the solution to offer more free training."
"The solution could improve the upgrades. In Brazil, it's difficult. The price is very high and it is not an easy process."
"I cannot think of a specific area that needs improvement."
"I would not like to see any additional features included in the new release of the HPE Alletra Storage. We're still new to the solution. So far, it's fine."
"HPE Alletra Storage pricing can be improved. The pricing, licensing, and software have changed."
"HPE Alletra Storage could be improved with greater compatibility of the HPE KVM or VM hypervisor with our other products, which would allow us to migrate off of VMware."
 

Pricing and Cost Advice

"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"Pricing is very competitive, and it's better than other competitors."
"There are no licensing fees aside from the support."
"We feel that the pricing is fair and the licensing process was easy for both."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"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."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
"I think we pay around 100 grand per year for three arrays or four arrays."
"The main competitor in the market for HPE Alletra Storage is Dell Storage, as they are selling at a low price."
"Its licensing is good. Pricing-wise, there can be a little bit more flexibility. It would help to have different sizes. However, it fits into the budget that we have, so we are happy."
"It is reasonably priced."
"Its price can be optimized."
"So far, so good."
"HPE was a clear winner on price per terabyte. It was very smooth."
