Sentiment score
6.7
HPE Alletra Storage customer service is praised for expertise, rapid issue resolution, and strong collaboration, despite occasional response delays.
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.
We have four-hour support, and 99% of our issues are resolved within that timeframe.
Last week, a ticket that needed to be solved in six hours took one week.
As soon as we have a problem, we open a ticket with them, and they immediately get back to us well within the four hour SLA that we have with them.

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.
HPE Alletra Storage requires improvements in pricing, interface, setup, AI features, NVMe support, integration, and customer resources.
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.
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.
They would like to have one tool that can take them everywhere. There should be a single pane of glass.
Most importantly, there is going to be the flexibility of moving compute and storage on Alletra MP.
 

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 Alletra Storage offers competitive pricing, flexibility, and quality support, though initial costs can be high and complex.
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.
For future use, we bill based on device consumption rather than the traditional datacenter model.
The predictability of having that one-time cost is everything for the data center.
It's expensive.
 

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 Alletra Storage offers intuitive management, high-speed performance, and cloud-like efficiency, enhancing storage performance and cost efficiency.
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.
With NVMe drives, a single drive can provide up to thirty thousand IOPS.
The guarantee of data availability is very important to us. Data runs everything.
The guarantee of data available to our organization is important. We're a manufacturing company. If our systems go down, we lose dollars every minute that system's offline.

Featured Reviews

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.
Hassan_Zaki - PeerSpot reviewer
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.
Anand Algesan - PeerSpot reviewer
Provisioning and encryption ease improve data storage efficiency
To improve HPE Alletra Storage, it needs to have a true active-active controller; it claims to have an active-active controller from the back end, however, the second node is pretty much sitting there doing nothing. The MV 10000 series, which is the next series, is an improvement to HPE Alletra, and HPE is already doing that. In the next release, I would prefer to see better dedupe features; I know other companies do excellent dedupe, and they have protection group policies, meaning you have immutable data in case of a ransomware attack. If you're on the SAN, it should give you a way to protect that data without being erased. Other vendors have that capability built-in, ensuring that you can't erase the data, so features similar to that would be great.
