By opting for the gold subscription every three years, you get a free upgrade to the latest controller release.
If you wait more than seven years to buy another one, you get a return on your investment.
The return on investment is very good.
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 we activate the 3PAR call home function, then the remote technician always has access to our StoreServ and provides strong suggestions to improve our 3PAR performance.
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.

Pure FlashArray X NVMe offers scalable storage with low latency, easy upgrades, though capacity customization and high costs are noted.
Sentiment score
7.5
HPE 3PAR StoreServ offers scalable storage, efficiently handling diverse workloads and future needs, with minimal upgrade complexity issues.
Sentiment score
7.4
HPE StoreOnce is scalable for enterprises, though some models require planning due to capacity limits and additional licensing.
You cannot increase capacity if latency is present.
It is highly scalable.
It is suitable for both medium-sized and enterprise businesses.
The ability of HPE StoreOnce to scale is strong when more sizing options are available.
The scalability of HPE StoreOnce is very good.
 

Stability Issues

8.1
Pure Storage offers exceptional stability and reliability with outstanding support, consistently achieving high user ratings for performance and service.
Sentiment score
8.1
HPE 3PAR StoreServ is stable and reliable, with minimal downtime, seamless updates, and effective support for setup challenges.
Sentiment score
7.7
HPE StoreOnce is highly stable with consistent performance, rare issues swiftly resolved, and reliability improving with newer models.
During the eight years, there have been no problems such as hardware failure or stopping.
I would rate the stability of the solution as a ten out of ten.
I would rate the stability of the product at seven out of ten.
HPE 3PAR is a very stable solution from HPE, and people have been using this for more than five years.
My experience with the stability and performance of HPE 3PAR StoreServ involved one crash, which was caused by failing hardware.
For the stability of HPE StoreOnce, based on customer feedback, I rate it highly as one of the most stable products in the backup and archiving line.
 

Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
HPE 3PAR StoreServ needs improved usability, support, integration, and cost management while enhancing performance, efficiency, scalability, and cloud compatibility.
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.
In Pakistan, some parts are not readily available, and we need to import them from Singapore or other countries.
HPE 3PAR StoreServ might be missing certain features available in newer products.
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.
HPE 3PAR StoreServ pricing ranges from $60,000 to $2 million, with competitive rates but costly additional licensing.
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.
It is expensive, however, when we compare it to the features provided by HPE, the price-to-performance ratio is very good.
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.
HPE 3PAR StoreServ excels in performance and integration, offering ease of use, automation, and robust storage management features.
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.
There is no downtime when we upgrade our 3PAR systems.
I find the HPE 3PAR StoreServ valuable for its ease of use and resilience, which is beneficial.
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.

Uninterrupted upgrades accelerate performance with good support
I would rate the solution eight out of ten. It should be noted that in Pakistan, some parts are not readily available, and we need to import them from Singapore or other countries. We encountered an issue with a customer where the midplane failed and was not available. We had to wait for several days for a replacement, even in a 24/7 support case. Additionally, we faced motherboard failures in the customer's environment, encountering two motherboard failures simultaneously. We obtained one motherboard immediately, yet had to wait ten days for another. These issues should have been resolved promptly given the 24/7 support level.

Measuring Up: EMC XtremIO and HP 3PAR
Leading up to EMC World 2015, IT Central Station asked how I would compare EMC XtremIO and HP 3PAR. Until recently, the flash storage conversation in my organization and many others has centered on XtremIO and Pure Storage, the leaders of the all-flash array (AFA) space. To that end, I've written a…
