All-flash storage has unified my clients’ workloads and has reduced TCO through efficient data services
The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors. IBM, Lenovo, and Dell are more aggressive on prices. It is a very complicated market, especially now, and I understand the prices are higher at Everpure because of the software and all the enhancements it has. However, in this competitive market, we have a big problem selling to customers that are on a tight budget. A product with better pricing would be a win in the end. The RC or C20, for example, was a very good product that I could sell more easily than other options. Everpure FlashArray//C is sufficient for most workloads and virtualization workloads if you do not have very large databases. A product like that helps, and perhaps a new product in the future that is a little cheaper than the current options would be a possibility to gain more market share. I see the return on investment clearly from using Everpure FlashArray, but the challenge is selling it to customers for the first time. There are many customers who fall in the sweet spot where they are too small for an X or even a C model. They need something a little cheaper, they have the money for a cheaper version, and they need the performance of a Pure system. These customers could be more easily approached if Everpure offers a version of a local device in the future that is even cheaper than the C-class. I am trying now to help customers understand the concept behind AG1. I know that AG1 is not profitable if capacity is less than 50 terabytes. However, some customers would be very willing to pay for 25 terabytes in a cloud operated by Pure and to have it accessible with very good speed. We will see what the future brings.

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

"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"Very efficient storage"
"It upgrades in place which means we'll be using it well into the future."
"Everpure FlashArray has reduced downtime in some situations, reduces downtime considerably, and can help perform upgrades or replacements of certain hardware or its firmware without shutting the machine down."
"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."
"Pure Storage is an amazing solution."
"Pure Storage FlashArray has helped us decrease the storage footprint in a significant way; the dedupe and compression that they have is really good, and we're getting about four to ten in the deduplication and compression."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"I like the fact that when I log in, I can get access to all of my different infrastructure components, and I can manage them through the web portal, and that makes things very easy as opposed to having to jump through different management interfaces or administration consoles."
"The features of HPE Alletra Storage that I appreciate the most are the UI."
"The feature I appreciate most about HPE Alletra Storage is compression."
"Alletra has helped us reduce time spent on storage."
"The feature of HPE Alletra Storage that I appreciate the most is the GreenLake suite one-stop shop; it has benefited my organization by allowing us to reduce our licensing costs from VMware from about 170,000 to about 70,000."
"The features of HPE Alletra Storage that I appreciate the most are speed and reliability."
"Since the deduplication and replication parts are there, the data is compressed and stored, which is why users are happy with the storage performance."
"There is ease of use for junior admins. We have VMware integrations for data stores, cloning operations of existing data stores, and InfoSight analytics."
"The storage serves the virtual environment. Most of our applications run in the virtual environment, and it serves nearly 30% of the bank's capacity."
"The FlashCore modules support more value to the architecture due to their unique characteristics."
"IBM FlashSystem 9100 NVMe is easy to use and comes with good performance."
"The technical support is good."
"The high performance and high availability improved our overall processes."
"Its ease of use, performance, and hardware compression is very useful feature."
"IBM FlashSystem 9100 NVMe is a stable solution."
"The product is a game-changer; IBM changed the game architecturally by moving computational resources into the flash media."
 

Cons

"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."
"Pure Storage FlashArray has not helped decrease the total cost of ownership."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"They have a product, FlashBlade, which is their object storage integration, and that's something that we haven't integrated with yet. This might be an area for additional focus as it would play into scalability, because the very nature of object storage is that it's infinitely scalable."
"Pure Storage support could be a little better."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"I would like FlashArray to add reports that help us forecast our predicted resource needs based on current usage."
"Pure Storage had operational challenges between 2016 to 2018, impacting perceived reliability."
"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."
"For the 6000, we'd like to see active-active controllers."
"In HPE Alletra Storage, areas that have room for improvement include the network-attached storage, specifically the NFS performance."
"I have not seen a tangible return on investment with HPE Alletra Storage."
"On a scale of one to ten, I would give HPE Alletra Storage around a seven."
"Maybe they could just reduce the number of racks and the amount of rack space."
"When you configure it, the system has to be connected to the Internet. Otherwise, you cannot configure it. That is the most difficult part. They need to have something that does not require a connection to the Internet."
"I'd like to see a smaller chassis in the hybrid arrays."
"Deduplication and compression should be improved."
"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."
"The storage system itself should have built-in capabilities for different ransomware attacks."
"Other vendors have included a block and file system. IBM doesn't include a file system."
"Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex."
"The solution's compression feature could be better."
"The efficacy of the GUI in IBM FlashSystem 9100 NVMe could be enhanced, and it would be beneficial to include a feature that can prevent ransomware attacks."
"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."
 

Pricing and Cost Advice

"Our costs are around $100,000."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."
"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."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"It's expensive, but you get what you pay for."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"Its pricing is very competitive."
"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 main competitor in the market for HPE Alletra Storage is Dell Storage, as they are selling at a low price."
"Its price can be optimized."
"For us, its price is good."
"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."
"So far, so good."
"Compared to its competitors, IBM's offering is the most cost-effective."
"The solution is priced well."
"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."
"The product has an average cost."
"The solution's price is competitive."
"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."
"The price of the FlashSystem 9100 NVMe is reasonable."
"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."
