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.

More IBM FlashSystem 9100 NVMe pros

Cons

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

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

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

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

"They could add more support for file storage and different types of storage."

"There are some challenges with data encryption and reduction."

"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 would like to see VNC integration or be able to use Pure Storage with VNC."

More Pure FlashArray X NVMe cons

"The solution could improve the upgrades. In Brazil, it's difficult. The price is very high and it is not an easy process."

"The only challenge was having to register with GreenLake, even though we weren't using it. Some places didn't have access to the internet - and if you don't have access to the internet, how can you register? If you can't register, you can't create data storage. This was one of the big drawbacks."

"In my case, HPE Alletra Storage does not provide a cloud-like operational model on-premises for managing data infrastructure."

"HPE Alletra Storage does not provide a cloud-like operational model on-premises for managing data infrastructure."

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

"HPE Alletra Storage pricing can be improved. The pricing, licensing, and software have changed."

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

More HPE Alletra Storage cons

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

"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."

"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."

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

"There is a tool provided by IBM for repairing batteries which can only be utilized by those who have an IBM technical advisor under service contract. However, for individuals who do not have such a contract, the tool can be difficult to use and requires a zip file copy. I believe that it would be greatly beneficial if the tool were made more user-friendly and accessible for all individuals who need to repair batteries."

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

Pricing and Cost Advice

"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."

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

"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 licensing is on a yearly basis."

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

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

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

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

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."

More HPE Alletra Storage pricing and cost advice

"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."

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

"The tool's pricing is competitive."

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