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.

Quotes from Members

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

Pros

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"Technical support has been helpful and responsive."

"What I really like about this program, is that it is easy to use and easy to configurate."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

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

"The initial setup was extremely simple and straightforward."

"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."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

More Pure FlashArray X NVMe pros

"It's good for preventing problems before they occur."

"We are quite happy that we got that option and have implemented this option till the last level of our VMs, and our testing and our requirements were met successfully in this storage."

"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 GreenLake AI Ops enables me to get assistance from the senior support engineers without having to go through support escalations."

"HPE Alletra Storage scales effectively with the growing needs of my organization, and I don't see limitations or complexity for growth at the moment, as it has been selected among the top players."

"The features I appreciate most about the HPE Alletra Storage are its ease of provisioning storage and management."

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

"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."

More HPE Alletra Storage pros

"Its ease of use, performance, and hardware compression is very useful feature."

"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."

"The features I find most valuable include its use for storage and performance."

"The solution is more available for IOPS warehousing, resolving issues, and reporting than other products."

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

"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."

"The most valuable features of IBM FlashSystem 9100 NVMe are its steady performance and usefulness in high-traffic environments."

"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."

More IBM FlashSystem 9100 NVMe pros

Cons

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

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

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"Adding some functions to the product would be beneficial."

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

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

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

"The UI for this solution needs to be improved."

More Pure FlashArray X NVMe cons

"HPE can improve HPE Alletra Storage by adding some features to be available from the offline GUI, especially related to snapshots and taking a snapshot for the whole storage, as some customers need this feature."

"I'd like to see a smaller chassis in the hybrid arrays."

"Reducing the price for HPE Alletra Storage would be fantastic."

"It could use improvement in correctly identifying and naming the systems. The solution keeps changing the names of everything. It's been hard to track."

"To improve HPE Alletra Storage, it needs to have a true active-active controller; it claims to have an active-active controller from the back end, however, the second node is pretty much sitting there doing nothing."

"I'm going to skip discussing how HPE Alletra Storage can be improved as I'm not in the technology area right now and haven't paid attention to that."

"We haven't had any issues with the solution so far."

"The licensing could always be cheaper."

More HPE Alletra Storage cons

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

"I would like to see IBM products become more affordable because they can be quite expensive, which limits their accessibility to a broader customer base."

"IBM FlashSystem 9100 NVMe is currently at the end of its lifespan and will soon become obsolete in the markets."

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

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

"The tool's architecture is complex. It also needs to add data utilization reports."

"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."

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

Pricing and Cost Advice

"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."

"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."

"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."

"The support cost per array is about $20,000 a year for 24/7 support."

"The product is expensive."

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

"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."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"Its pricing is very competitive."

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

"Its price can be optimized."

"For us, its price is good."

"There is a license. HPE Alletra uses a cloud-based model."

More HPE Alletra Storage pricing and cost advice

"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."

"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."

"The solution's price is competitive."

"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."

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

"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 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."
