Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Dell PowerStore requires enhancements in stability, integration, features, scalability, and user experience for better performance and customer satisfaction.
HPE Alletra users seek NVMe integration, improved setup, intuitive management, AI capabilities, and better compatibility with protocols and platforms.
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
Storage replication should be essential.
Infrastructure Specialis at a tech services company with 1-10 employees
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.
CISO Admin at a analyst firm with 51-200 employees
Pricing must also be considered, as Dell PowerStore is quite expensive compared to competitors in the market like HPE Alletra, Huawei Dorado, or Hitachi storage, for example.
Unit Head - Technology Services at Shahnawaz Ltd
The main reason why people move to Pure Storage is because it's simplified.
IT Director at a recreational facilities/services company with 10,001+ employees
They shouldn't strip out anything from InfoSight. That is really helpful software to see how the storage arrays are performing and has helped us do a lot of troubleshooting.
Senior Director, Information Technology at a tech vendor with 201-500 employees
They would like to have one tool that can take them everywhere. There should be a single pane of glass.
Sr. Storage and Virtualization Engineer at a tech services company with 201-500 employees
Most importantly, there is going to be the flexibility of moving compute and storage on Alletra MP.
Solution Architect at CBTS
 

Setup Cost

CISO at a construction company with 10,001+ employees
In terms of whether my company could reduce the power consumption with Dell PowerStore, I would say that my company had a use case with a customer around three weeks ago where their old Dell EMC VNX Storage System used to draw about 2500 watts compared to Dell PowerStore which drew about 800 watts, which is a really a big saving looking at the twenty-four hours and seven days of usage of the system.
Data Center Consultant at a retailer with 11-50 employees
With NVMe drives, a single drive can provide up to thirty thousand IOPS.
Solution architect at Aeris
The guarantee of data availability is very important to us. Data runs everything.

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.
reviewer2304864 - PeerSpot reviewer
Vmware Windows Senior Engineer at a manufacturing company with 10,001+ employees
Resilience has supported proactive management and secured audit readiness across multiple sites
The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place. I see Dell PowerStore playing a bigger role in the future because we are starting to use it more, and that is pushing it. The biggest return on investment for me when using Dell PowerStore is scalability. Scalability is key. I can amplify that scalability is the biggest return on investment because we have redundancy between two sites; if something goes down, we have to manage it, but we want to do it proactively.

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.
