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.

Data management operations are streamlined with impressive metrics and responsive support
Improving HPE Alletra Storage is challenging to answer because there are several different metrics to consider. From a performance perspective, the improvements and large jumps are fantastic as is. From a deployment perspective, I was a big fan of the on-premise deployment model and then connecting it afterward to GreenLake. Now that's being sunsetted. From a sensor and metric standpoint, there is just enough data without getting useless metrics, where you become blind to what it provides. The HPE Storage Technical Assistance Center is still probably the best out of all the storage vendors. It's difficult to improve upon being able to call in and get assistance almost instantly.

Quotes from Members

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

Pros

"It releases those to new teams within minutes at a very small storage cost amount."
"From the first test that we have conducted, we are very satisfied with this solution."
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"While all these products have their own uses, Pure Storage FlashArray is in a market of its own."
"Using this solution has improved our consolidation ratio and it saves us a lot of space."
"It does efficient work of storing data while still delivering the performance that you would normally expect from a higher priced solution."
"It has a small footprint, as the current system is only four units per rack, it's got good speed for the price as it uses eMLC, an advanced type of SSD, and it's very scalable, and we're not paying for capacity as we get free controllers every three years."
"It's very fast, easy to use, and the cloud-based management is good."
"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."
"The initial setup is straightforward."
"It has cut batch job runtime in half, so we're seeing performance improvement throughout the organization."
"High performance and ease-of-management are the most valuable features."
"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."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks Cheaper than pure solid state without needing to actively manage where the data is located."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"HPE Alletra Storage is simple."
"Since we've implemented the solution, we've had zero downtime on the arrays."
"HPE Alletra Storage provides a cloud-like operational model on-prem for managing our data infrastructures, although I still interact with the SAN in the traditional on-prem way."
"It's user-friendly, easy to configure, manage, and very flexible for both VMware and physical servers, with very good compression and deduplication, which makes it one of the best in the market."
"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 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."
"HPE Alletra Storage helps simplify storage operations, with a friendly UI that is super easy so users can have a short tutorial and start working on it, while providing predictable performance and capacity for applications and delivering competitive pricing, easy management, and almost 99.999 uptime availability without issues."
 

Cons

"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."
"In Pure Storage FlashArray, the area with room for improvement is local MFA login."
"We had one instance with an eight-hour outage in our primary data center because the upgrade to the controller failed, and the controller redundancy didn't work."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"Technical support needs improvement. With respect to them being able to respond, they're more marketing people, less technical."
"There is not a great need for improvement, but better pricing could be beneficial."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"The monitoring matrix and its dashboard need work."
"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 solution as it is right now is not very stable. The stability seems to have eroded."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"In future releases, I look forward to more AI features."
"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 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 does not really provide a cloud-like operational model on-prem for managing data infrastructure. The limitation is that we cannot really downscale HPE Alletra Storage, even if we are running on the GreenLake; that's the nature of the storage."
"The challenge I face is that the recent models launched are not available now. When we pitch a solution to a customer and sell HPE Alletra 6000, the customer sees that the product has been discontinued by HPE."
"The deployment was a little rocky."
"HPE Alletra Storage pricing can be improved. The pricing, licensing, and software have changed."
"HPE Alletra Storage is considered expensive compared to competitors like Dell and Huawei. Many times, we lose deals due to price even though it is the best solution in the market."
"I'd like to see larger cluster sizes beyond four nodes."
 

Pricing and Cost Advice

"We are finding the TCO of flash to be lower than SSD implementations."
"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
"We purchased a license to use this solution and we pay for the storage ourselves."
"We have seen a reduction in TCO."
"You get what you pay for. It is expensive, but it really works."
"It could always be lower, but it's okay."
"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"We have an Evergreen Storage subscription, which I think is a great feature."
"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."
"It is fairly priced. It is in line with industry standard pricing and cost models."
"Overall, it was good. It had a good price per gigabyte."
"The solution is expensive and can cost around five lakhs."
"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."
"There is a license. HPE Alletra uses a cloud-based model."
"HPE was a clear winner on price per terabyte. It was very smooth."
"Its price can be optimized."
