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.

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.

High-speed data processing has improved billing cycles but performance headroom still needs growth
In terms of improvement regarding IBM FlashSystem 9100 NVMe, I can compare with other competitors, especially regarding solution architecture. Data resiliency can be a concern because IBM can reach up to only four controllers, while others like Dell EMC can support up to eight controllers with better resiliency without service staff. Additionally, the SBC one benchmark is a storage performance console that stresses different storage solutions like Dell EMC and NetApp. It generates metrics of IOPS and latency, showing that the competition can have two million IOPS, significantly outperforming IBM's capabilities. As for the capability of scaling, we can see the limitations in reaching such high-performance levels.

Quotes from Members

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

Pros

"With Pure Storage FlashArray we have been able to deploy several thousand VDI servers, virtual machines, very quickly and efficiently."
"The compression and deduplication features help to make the best use of the capacity."
"It has simplified our storage."
"Do it. I have zero reservations about recommending Pure to anyone who is looking for some really good all-flash."
"The product cheaper compared to other solutions concerning the technology that they are using."
"The support team is available all the time and they seem to know what they are doing."
"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"Alletra has helped us reduce time spent on storage."
"HPE Alletra Storage is simple."
"We have improved storage performance."
"The stability is incredible. We haven't had a single storage event since we put it into production."
"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 helps simplify storage operations, integrating with vCenter."
"The feature I appreciate the most about HPE Alletra Storage is how easy it is to provision storage."
"The features of HPE Alletra Storage that I appreciate the most are the UI."
"The FlashCore modules support more value to the architecture due to their unique characteristics."
"A key feature is that compared to storage systems that we've been familiar with over decades, IBM simply does not fail. The reason is that IBM is the only manufacturer that engineers its own flash module, and there is a key architectural difference from everything else that we have seen in the market. The difference is that the flash module has the computational capability, which allows reliability and capacity enhancements to be uploaded from the main controllers and run in each module. So, each of the flash drives becomes its own little storage system, and that is extremely effective architecture. In this field, with this type of system, IBM has made a statement. They've never had one of these modules cause an outage. So, the failure rates on these things are just in a whole different universe from what we were accustomed to."
"IBM FlashSystem 9100 NVMe is one of the leading storage systems in the world...I rate the solution's stability a ten out of ten."
"IBM FlashSystem 9100 NVMe is easy to use and comes with good performance."
"You get value for money, because the product is good in terms of control failure."
"The most valuable feature of the solution is its upgrades, as we don't have to do much homework because of its different controllers."
"IBM FlashSystem is an excellent product."
"It's easy to use, has good stability, and many features."
 

Cons

"There are a lot of things to improve."
"Pure Storage support could be a little better."
"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."
"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."
"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."
"They could improve the price."
"The price could be better."
"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."
"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."
"Pricing could be optimized, as it is always a challenge. The competition offers some storage solutions at lower prices, making the cost a significant factor."
"I don't have the numbers to quantify how much HPE Alletra Storage has reduced our data management operation expenses."
"We had a hiccup when we deployed our last SAN. The 6000 that came in, they were transitioning the onboarding to be fully cloud, GreenLake-driven. The problem was we're in a regulated air-gapped environment."
"The biggest challenge was again down on that unit. The power supply was not the correct power supply, and it took forever for them to send me the one that I needed. It took five months to get it."
"I have not seen a return on investment with the HPE Alletra Storage."
"The solution could improve the upgrades. In Brazil, it's difficult. The price is very high and it is not an easy process."
"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 solution's compression feature could be better."
"In terms of improvement regarding IBM FlashSystem 9100 NVMe, I can compare with other competitors, especially regarding solution architecture."
"We're not satisfied with the deduplication and compression for our volumes."
"Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex."
"IBM's support is not good. I experienced a big problem where I opened the console IBM Storage and would see that something was broken. I called the call centers, and I said, "I have a problem. My drive is not working." They want me to give them the serial number, I gave it to them and they told me "I cannot find your product. Your product is not here.""
"IBM is currently not offering volume-based encryption or compression, while other brands or IBM's competitors are doing it."
"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."
"In the future, the limitation is upgrading the same storage by adding a shelf to the desk. There is a limitation in the backend connection between the storage and extended shelf."
 

Pricing and Cost Advice

"The pricing is very attractive and it delivers performance for the money."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"Pricing is very competitive, and it's better than other competitors."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"Pure Storage has not helped to reduce our HANA licensing costs."
"For us, its price is good."
"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."
"Its price can be optimized."
"HPE was a clear winner on price per terabyte. It was very smooth."
"There is a license. HPE Alletra uses a cloud-based model."
"It is fairly priced. It is in line with industry standard pricing and cost models."
"Its pricing is very competitive."
"The pricing is somewhat high, but when customers choose HPE, they often prioritize the brand value over pricing. The pricing is higher compared to other vendors."
"The tool's pricing is competitive."
"The price of the FlashSystem 9100 NVMe is reasonable."
"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing an eight."
"The product has an average cost."
"The price of IBM FlashSystem 9100 NVMele can be considered affordable when taking into account the operating system that is required for it to function properly. This operating system, which is licensed by IBM, may carry a higher cost, but it is worth the investment for larger corporate entities, such as insurance companies, Fortune Five companies, and banks, who make up a significant portion of their target market. The FlashSystems are designed for larger corporations and multinational enterprises, and may not be the most cost-effective solution for smaller businesses."
"It's a lot less costly than cloud storage. People get surprised by the cost of cloud storage, which is extremely expensive and four or five times the cost of storage on-premises. People don't realize what they're spending on storage until they start getting bills from Amazon, Microsoft, and others. This is a good way to reduce your cloud storage expenses."
"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."
"Compared to other solutions, the cost of IBM FlashSystem 9100 NVMe is reasonable, with a one-time payment of around $70,000. However, additional support is available for $25,000 for three years. The overall maintenance cost is steep."
