Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Provides a cloud-like operation model on-prem for managing data infrastructure

I've always said I love that it's easy to use. At one point in time, we had a 3PAR. And with 3PAR, I always thought it was a little more difficult. There was so much more to maintaining it, setting it up, and everything. With the [HPE] Alletra [Storage], it's just easy. It's easy to provision space to use and to set up. InfoSight is invaluable to me. With it, I can just quickly go out there and see what is going on. Alletra provides a cloud-like operation model on-prem for managing data infrastructure. [HPE] Alletra [Storage] is very good for predicting problems and preventing them before they occur. InfoSight has really helped with that. I honestly don't have to look at it much. However, there's the alerting and everything that will tell us what's going on. That said, I check InfoSight every once in a while. [HPE Alletra Storage] reduced the time spent on storage provision. It's so much easier than the 3PAR. It's just so much easier. I don't spend time in there at all. The product improved our storage performance experience in terms of IOPS. Our end users that use the SAP environment were a little concerned at first. We said we were going to switch over from the 3PAR to the Alletra since they've always been more familiar with the 3PAR. However, when we moved them over, they noticed a performance increase.

Quotes from Members

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

Pros

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"The database workloads are pretty fast because I frequently move data from here to there."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"The high availability of the product is the most valuable feature."

"It has good, reliable, fast storage."

"The most valuable feature of this solution is reliability."

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

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

More Pure FlashArray X NVMe pros

"HPE Alletra Storage comes with zero downtime, which is its best feature. It has real-time replication available, so no additional features need to be bought when purchasing the system."

"Alletra has helped us reduce time spent on storage."

"We now have much more storage and the uptime is very good."

"More deduplication and compression are valuable because capacity matters."

"The configuration capacity it has to create a cluster for replication is excellent."

"The capability to predict problems and prevent them before they occur is exceptional in HPE Alletra Storage MP."

"It is the simplicity of the deployment. They have unified all the features they have."

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

More HPE Alletra Storage pros

"The high performance and high availability improved our overall processes."

"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."

"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."

"Good performance with a user-friendly UI."

"It is a very stable solution."

"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."

"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."

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

Cons

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"I'd like to see the product implement active replication for vehicles such as VMware."

"There is room for improvement in the pricing of the product."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"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."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

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

More Pure FlashArray X NVMe cons

"Sometimes, with HP, there may be language barriers, and they seem to cycle through tech a lot more. That said, overall, I always get the answers I need."

"It would be great if it cost less."

"They can continue developing their V vaults and peer persistence. They can implement active-active peer persistence so that our organization can use it."

"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 would like to see some form of direct connect fiber channel options."

"Moving from Nimble to Alletra was a little difficult."

"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."

"The energy usage could be further improved."

More HPE Alletra Storage cons

"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."

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

"The solution's compression feature could be better."

"The pricing should be more competitive."

"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."

"The support could be better."

"The ZIO interface could be improved."

"Deduplication and compression should be improved."

Pricing and Cost Advice

"The licensing is on a yearly basis."

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

"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."

"As far as the licensing costs, everything is included in the license."

"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."

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

"With VMware, we pay $300,000 annually."

"The product is expensive."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"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."

"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."

"HPE was a clear winner on price per terabyte. It was very smooth."

"It is reasonably priced."

"Its price can be optimized."

"For us, its price is good."

More HPE Alletra Storage pricing and cost advice

"The tool's pricing is competitive."

"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."

"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."

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

"The product has an average cost."

"The price of the FlashSystem 9100 NVMe is reasonable."

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