Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Dell PowerMax needs better deduplication, automation, cloud integration, documentation, pricing, and customer support for enhanced user experience.
Users seek improved deduplication, integration, interface, setup, support, storage, performance, pricing, and cloud features in HPE StoreOnce.
We would appreciate a built-in transparent failover in the next release to eliminate the need for a separate metro cluster.
Sales Director at systemzwo group
One way to improve the product is to add an operational assistant that doesn't depend on VMware.
Sales Manager at Multicomputos PR
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.
Cloud Architect at DXC Technology
Compared to competitors such as NetApp, which integrates with public cloud hyperscalers (GCP, Azure, AWS), Dell PowerMax lacks in this aspect.
Dell can assist by providing plug-and-play integrated templates that allow customers to drag, drop, modify, and connect with any target system for generating snapshots without logging into the storage directly.
System and Storage Admin at a financial services firm with 1,001-5,000 employees
Dell PowerMax NVMe is very reliable storage and cannot experience downtime.

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
Dell PowerMax is costly but premium, with high support costs, yet discounts are possible through vendor negotiations.
HPE StoreOnce setup is costly initially, but offers competitive, feature-rich pricing with capacity-based licensing and bundled support.
While the prices may be higher than those of other vendors, we see it as a market leader with benefits.
Manager, System Infrastructure & Security at Organik Kimya San. ve Tic. A.S.
The support can be a bit pricey, but the solution is more cost-effective than anything else out there.
Sales Manager at Multicomputos PR
I would rate the solution as an eight out of ten in terms of costliness.
Sales Director at systemzwo group
The higher cost compared to other vendors is justified by additional features, vendor-managed upgrades, and superior support services.
It is the best choice for large projects in terms of price and features compared to midrange solutions.
Presales Engineer at Project Informatica srl
The price is starting from $500,000.
Senior Sells at Enterprise Sigma Technology
The solution is quite expensive, possibly rated around seven and a half on a scale of one to ten.

Jaehoon Oh - PeerSpot reviewer
Chief Technology Officer at Lambda256
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.
MayankChauhan - PeerSpot reviewer
Lead Consultant - Cloud & Infrastructure Services at Infosys
Delivers essential support and performance for intensive operations in real-time environments
Our infrastructure is spread across the private as well as a public cloud. Our requirement was that the IOPS latency should not be more than one millisecond. If anything goes beyond one millisecond, it's a problem for us. We wanted a system that could handle the transactions and meet our latency requirements. There are performance benefits for sure. The amount of deduplication and compression offered by Dell PowerMax is quite good, especially with databases. Dell PowerMax delivers optimum performance and reliable support, integral for handling failures and ensuring operational continuity. The performance capacity optimization and support we receive from Dell are also valuable.

HPE Product Manager at a tech services company with 51-200 employees
Collaborate effectively with partners and benefit from robust data management capabilities
The functions of HPE StoreOnce that I find most valuable are its deduplication and replication options. These features save data and reduce the size of data significantly. If the actual size for backup data is 100 terabytes, using StoreOnce, it will be around less than 10% of the original size due to the 1 to 10 deduplication ratio. So, compression and replication are critical features I appreciate. Additionally, adaptive backup and restore capabilities of HPE StoreOnce are indeed very helpful functions. As I know from my technical team, the process is very easy for end users because the GUI and user experience with StoreOnce are straightforward. They can restore their backups at any time. An important feature of StoreOnce is that they can reserve an amount of storage capacity as protected capacity for a limited time, safeguarding their data against intrusion and other interactions. Based on feedback from customers, StoreOnce is regarded as a highly useful solution for backup. I am satisfied with the security aspects of HPE StoreOnce, but it's crucial for any company to maintain a multi-layer security approach. Starting with a firewall is essential for maintaining their environment. Additionally, security features on StoreOnce are useful. I believe that no company should rely solely on one layer of security; they should adopt a multi-layer security strategy that begins at the network level and extends to their internal solutions.
