It's been trouble-free the entire time, with very high performance, as it has been designed and built properly.
We have reduced infrastructure but the same performance.
If we request the price for StoreOnce as a standalone product, it tends to be higher than when it is included in a larger solution where we can receive better discounts.

Sentiment score
7.6
HPE StoreOnce customer service is highly regarded for its responsiveness, knowledgeable staff, reliable service, and flexible support offerings.
With Pure FlashArray X NVMe, we need to escalate the issue and get an account manager for its resolution.
We also had one outage where a controller of one of the products had failed and had to be replaced on-site.
Customers always have their issues resolved promptly.
If necessary, they will search for a specialist within their Dell network who we can approach with our questions.
I would rate the technical support of Dell PowerStore between nine and ten out of ten.
They're responsive, knowledgeable, and have a quick turnaround.
HPE's support is very good, proactive, and monitored through InfoSight.
When we open a case for support during installation or other matters, they are always timely and provide full support.

Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Dell PowerStore needs enhanced replication, stability, integration, user interface, pricing, support, monitoring, and documentation for improved user experience.
Users seek improved deduplication, integration, interface, setup, support, storage, performance, pricing, and cloud features in HPE StoreOnce.
Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe.
We would appreciate a built-in transparent failover in the next release to eliminate the need for a separate metro cluster.
I'm eagerly anticipating the roadmap's promise of introducing multiple controllers, which could significantly boost scalability and resilience.
If you want to delve into where your I/Os are going, the reporting might need more in-depth information to make informed decisions.
In my organization, we have had to go through two weeks with no replication, which is not very handy for our production environment.
Something needs to be done with the caching to ensure that if some issue occurs, there needs to be an ability to disable caching during maintenance to make it static, safe, and good.
It is well-positioned on the radar, with a mature and stable solution.
The benefits of StoreOnce, which we discussed, include its compression capabilities with a ratio of 1 to 10.
While the solution does everything expected, it would be beneficial if AI could be integrated for optimization and monitoring.
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
Dell PowerStore offers value with performance and deduplication; pricing varies by market, with potential expansion cost concerns.
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.
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.
Likely the cost is $400,000 whereas IBM may be $250,000.
Based on my experience, the cost of Dell PowerStore for around 500 GB of capacity is very competitive compared to any other platform in the market.
There's no need to pay for a license; it's all-inclusive.
The solution is quite expensive, possibly rated around seven and a half on a scale of one to ten.
 

Valuable Features

Pure FlashArray X NVMe offers exceptional performance, reliability, scalability, and seamless VMware integration, enhancing workload efficiency and user experience.
Dell PowerStore excels with VMware integration, AI management, efficient storage, and NVMe speed, enhancing scalability and energy efficiency.
HPE StoreOnce provides efficient data management through high-performance deduplication, scalability, and seamless integration for optimal backup and storage solutions.
Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator.
The platform's robust features include excellent sustainability tracking, and a comprehensive dashboard offering insights into IOPS, bandwidth, performance, and virtual activities.
Its data compression feature is the best that we have ever seen.
The solution promotes data reduction, often meeting the compression ratio.
The PowerStore's compression ratio is even higher than the Unity system.
The deduplication part of the solution is valuable since, as a user, you get more space for less money.
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.
The most effective features for data deduplication are maximizing storage capacity and minimizing expenditure.
The recovery is important.

Jaehoon Oh - PeerSpot reviewer
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.

Integrated AI and clustering enhance storage operations effectively
I promote and recommend Dell PowerStore for all workloads to my clients and customers. Most of my customers have one appliance per site. Approximately 80% of my customers have Dell PowerStore implemented in their data centers. We always use CLS as another Dell solution for cybersecurity and data security. The CLS is integrated with the Data Domain, PowerProtect Data Domain, not with Dell PowerStore. Windows, Linux, and some customers use Red Hat or SUSE. We have many operating systems working with Dell PowerStore in the same environments and data centers. CloudIQ and Storage IQ are used by some customers, but Apex AIOps has not been widely adopted yet. Dell PowerStore has integration with VMware and Kubernetes. Most workloads work fine and have very good integration with Dell PowerStore, except for one or two specific workloads in the market. On a scale of one to ten, I rate Dell PowerStore a nine.
Andrew Mcbeath - PeerSpot reviewer
Maximized storage capacity and minimized costs and an easy setup
Most of our client base is between fifty to five hundred end users. We occasionally recommend high-end HPE products for larger clients needing performance and reliability. Our clients predominantly use HPE StoreOnce for small business purposes in industries like dairy and finance Our clients have…
