Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

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.

Pros

"Technical support has been helpful and responsive."

"The most valuable feature of this solution is its ease of use."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"The most valuable features of this solution are its ease of use and performance."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"The initial setup was extremely simple and straightforward."

"The solution uses newer technology for deduplication and compression."

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

More Pure FlashArray X NVMe pros

"Clients like the insights tools within the solution that came from Nimble and were pulled in."

"The tool's notable feature is that we don't need to log a case directly with the vendor. The tool has access to all the logs on-premises. This is an on-premises solution. Additionally, we can provision data as thick or thin provisioned. Moreover, it includes data grid duplication and compression features."

"In our evaluation process, both the cost of the solution and our familiarity with the way that solution worked were what stood out to us as driving factors, with no significant negatives to report."

"The stability is incredible. We haven't had a single storage event since we put it into production."

"The stability of the solution is rock-solid."

"The feature I appreciate most about HPE Alletra Storage is its simplicity."

"HPE Alletra Storage is simple."

"The most valuable features of HPE Alletra Storage that I have found are performance and ease of configuration. It's overall fantastic."

More HPE Alletra Storage pros

"The FlashCore modules support more value to the architecture due to their unique characteristics."

"It's easy to use, has good stability, and many features."

"It is a very stable solution."

"It is a very stable product. Stability-wise, I rate the solution a ten out of ten because we did not face any issues in the last three years."

"IBM FlashSystem 9100 NVMe is easy to use and comes with good performance."

"What I like about the product are its high availability, maximum efficiency in performance, and its ability to handle a high level of I/O operations."

"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."

"There are many valuable features of IBM FlashSystem 9100 NVMele I have found to meet my needs. Specifically, the maintenance cycle is a standout feature of this solution. The main component of the IBM FlashSystem 9100 NVMe is the maintenance of the batteries, which have a predetermined and reliable four-year life cycle. This is in stark contrast to other solutions that may use spinning disks, which can fail unexpectedly, causing unwanted downtime and maintenance. Having a predictable maintenance cycle is a significant advantage and has made this solution a preferred choice for me."

Cons

"I would like to see replication and DR features in the next release of this solution."

"In the future, I would like to see integration with enterprise backup systems."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

More Pure FlashArray X NVMe cons

"I have not seen a tangible return on investment with HPE Alletra Storage."

"A negative aspect would be that I can only get pool utilization from InfoSight, not on the local array. I have to pull metrics every month from InfoSight, and it would be easier if it were just available on the local array."

"I have not seen a return on investment with the HPE Alletra Storage."

"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."

"It was fairly difficult to migrate the data from 3PAR over."

"There can be more visibility and statistics for the customers to see. The customers would love to see AI."

"I'd like the solution to offer more free training."

"We had some issues while installing it on our servers. It required more resources while cross-checking. So, the initial setup process could be better."

More HPE Alletra Storage cons

"I'd like to be able to connect to tape drives behind the storage device to back up the tape if need be. We have all of our storage running in all-flash, and we make a copy on tape. Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex. We want IBM to add a feature where we could install a tape into the storage so that we can connect it through a single pane of glass. We'd like to have a feature in the IBM flash storage system so that we can connect backup tape drives through the IBM storage system and we can manage the backup tape from the storage system."

"In the FlashSystem 5200, there were only four ports of 32 fiber channels for the architecture. This has been resolved in the new generation."

"Other vendors have included a block and file system. IBM doesn't include a file system. And yet, it's very necessary for all organizations' networks to have file systems. We have other systems for the file system, however, ideally, we would like to have one system with these features."

"Deduplication and compression should be improved."

"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.""

"The solution's compression needs to be improved, as it's not the best."

"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."

"IBM is currently not offering volume-based encryption or compression, while other brands or IBM's competitors are doing it."

Pricing and Cost Advice

"The licensing is on a yearly basis."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"Our licensing fees are $500,000+ USD."

"Given its price, Pure is not the first option."

"We pay approximately $50,000 USD per year in licensing fees."

More Pure FlashArray X NVMe pricing and cost advice

"Its price can be optimized."

"It is fairly priced. It is in line with industry standard pricing and cost models."

"It is reasonably priced."

"The solution is expensive and can cost around five lakhs."

"Overall, it was good. It had a good price per gigabyte."

"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."

"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."

"So far, so good."

More HPE Alletra Storage pricing and cost advice

"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."

"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."

"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."

"Compared to its competitors, IBM's offering is the most cost-effective."

"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."

"The solution's price is competitive."
