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.

Disintegrated all‑flash storage has boosted ERP performance and delivers instant operational insights
I appreciate that HPE Alletra Storage is an all-flash NVMe storage with a disintegrated architecture, allowing me to enhance performance without needing to add capacity. If I'm buying the Alletra MP 10000 right now with two controllers and 24 NVMe drives, I can simply add a single controller to boost my performance without being stuck with the limit of two controllers at a time for upgrades. Seamless integration with existing infrastructure is absolutely important to our organization's strategy because otherwise, I would need to redo everything repeatedly, which consumes significant time. We do use the AI-driven insights in HPE Alletra Storage. The AI-driven insights for Alletra MP 10000 greatly assist our data operations by providing immediate access to insights without going into the storage or asking the storage administrator for data. This enables any storage manager to easily obtain insights regarding performance, IOPS requirements, disk usage, and compression ratios from anywhere in the world. In terms of predictive analytics features, HPE Alletra Storage automatically opens and enriches support cases with diagnostics during any storage issues, which drastically reduces the mean time to repair and eliminates manual log collection, resulting in much higher efficiency in support automation.

Quotes from Members

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

Pros

"The white glove customer service that I get is their greatest value."
"From the first test that we have conducted, we are very satisfied with this solution."
"We chose Pure Storage primarily because of its combination of performance and ease of use."
"Its array houses our entire production environment."
"NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support."
"Cuts VM deployment down to seconds and cuts latency under MS with amazing performance and very stable operation with no worries about how much it can handle."
"Pure Storage is an amazing solution."
"Redundancy and the fault tolerance of the platform are the most impressive."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"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."
"Data Compression: Up to 80% space reduction in the database"
"It has cut batch job runtime in half, so we're seeing performance improvement throughout the organization."
"The initial setup is straightforward."
"Tegile All-Flash Storage Arrays deliver maximum performance, high density, compelling economics and it is ideal for latency-sensitive, business-critical workloads such as online transaction processing, real-time analytics, decision support, and data warehousing."
"Ease of Use: Someone can learn it in only few hours Performance: Easy Tier is doing miracles Data Compression: Up to 80% space reduction in the database"
"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."
"3PAR took it to another level, but Alletra and GreenLake have impressed me utterly and totally and made life easier."
"The solution has been rock-solid since we've had it."
"My experience with the pricing and setup costs of the HPE Alletra Storage was phenomenal, which is one of the reasons our organization decided to go with it, as the setup costs were in some cases half the price of some of the other competitors with even more features."
"The stability is incredible. We haven't had a single storage event since we put it into production."
"The features of the HPE Alletra Storage I appreciate the most are one SKU and the speed of the resources. The solution has reduced my data management operation costs and time."
"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."
"Feature-wise, it's pretty simple; just a one-click button to enable it, so implementing it was pretty easy too."
"The configuration capacity it has to create a cluster for replication is excellent."
 

Cons

"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"I wish they could collaborate more with the other vendors internally, instead of us opening cases with Cisco, HPE, VMware, etc."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"In Pure Storage FlashArray, the area with room for improvement is local MFA login."
"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room. We want to be able to read through the encryption."
"CIFS and SMB Shares cannot be mounted directly."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"Snapshots are not as easy to access as on a NetApp device."
"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"The monitoring matrix and its dashboard need work."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"We had some support engineers who were not qualified to do the work, and we had to wait until we could get some qualified people to come out to fix it, which was a low point from support."
"I have no improvements or suggestions for additional features for the next release of the HPE Alletra Storage at the moment."
"It would be better if there were an option to incorporate the NVMe feature alongside other storage tiers. Currently, the system operates on Autotier but can manually peer and mix different types of drives, such as SAS and SATA drives."
"I have experienced some issues, not necessarily downtime. That said, we had some controller issues at one point; however, since I have redundancy, we really didn't experience any downtime."
"I do not have any issues with it. It has been good for us. There are no cons that I see, and that is why we use it."
"I'm going to skip discussing how HPE Alletra Storage can be improved as I'm not in the technology area right now and haven't paid attention to that."
"Moving from Nimble to Alletra was a little difficult."
"We faced many problems with HPE Alletra 6000, and we did not understand whether it was because of some issue with the controllers or the disk."
 

Pricing and Cost Advice

"The price of the solution can be a bit expensive. There is an additional fee for support."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"The pricing of Pure Storage FlashArray is reasonable."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"The best features come included without any additional cost."
"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."
"I think we pay around 100 grand per year for three arrays or four arrays."
"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
"So far, so good."
"Its pricing is very competitive."
"The main competitor in the market for HPE Alletra Storage is Dell Storage, as they are selling at a low price."
"Overall, it was good. It had a good price per gigabyte."
"It is fairly priced. It is in line with industry standard pricing and cost models."
"The solution is expensive and can cost around five lakhs."
"It is reasonably priced."
"For us, its price is good."
