Dell PowerScale and Dell PowerStore are competitors in the enterprise storage solutions market, with PowerScale having the edge in scalability and unified storage management, while PowerStore excels in integration with VMware and data reduction capabilities.
Features: Dell PowerScale is well-suited for high-performance, large-scale storage needs due to its ease of management and scalability using the OneFS operating system. It supports features like SmartQuotas and policy-based management. PowerStore is designed for versatility within VMware environments, supports NVMe storage, and offers advanced data reduction features like compression and deduplication, making it efficient for rapid access.
Room for Improvement: Dell PowerScale is less cost-effective for smaller operations, displaying a lack of native cloud integration. Enhancements are needed in areas such as NFS support and load distribution. Dell PowerStore needs improvements in data reduction consistency and integration with VMware. It would benefit from better synchronous replication and enhanced cybersecurity features.
Ease of Deployment and Customer Service: Both solutions offer strong on-premises deployment. PowerStore extends options to public and private clouds, providing greater flexibility. Their technical support is recognized for reliability, although both can improve support consistency. Dell's proactive service is appreciated across products.
Pricing and ROI: Dell PowerScale is perceived as high-priced but justified by its performance and scalability, yielding substantial ROI by lowering administrative costs. Dell PowerStore also comes with a premium price but offers a favorable price-to-performance ratio, credited to its effective NVMe capabilities and operational flexibility, resulting in a commendable total cost of ownership.
Something such as Dell PowerScale puts us ahead of all of our competitors because of the speed at which we can iterate while we are on set.
Despite being more expensive than Huawei, it is stable and most enterprises accept the price due to its stability.
In terms of Dell PowerScale (Isilon) specifically, we have seen a return on investment due to faster performance than our last few storage arrays, and the general usability is a lot better.
If you purchase storage with 300 terabytes, you can easily achieve one petabyte of effective capacity.
It's been trouble-free the entire time, with very high performance, as it has been designed and built properly.
We have seen a return on our investment in Dell PowerStore; definitely our cost per terabyte has been very good compared to some of the other vendors that we would have been using previously, and our performance benchmarks have exceeded what we were expecting.
Support online is definitely a ten out of ten.
When we face issues, we raise a ticket through the valid portal, and they respond immediately and assign a local engineer to coordinate the support process.
On a scale of one to ten, I would rate Dell's technical support a ten.
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.
On a scale of one to ten, I would rate Dell support as a ten, focusing on that aspect alone, because it's what allows me to sleep at night.
We started on PowerScale with around about 300 terabytes and are now two and a half petabytes, still on the same file system.
That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.
As an unstructured data storage solution, writing into it and accessing it from the other nodes is highly scalable with no issues.
It has built-in health monitoring, and management is supported with VMware plugins, SNMP protocol, and it provides an HTML5 graphical interface.
The ability to add capacity in single drive increments is important to my organization, as it provides flexibility beyond the usual vendor-defined packs.
The solution's scalability is a ten out of ten.
Since we have good protection levels, the data is secured and replicated across the disks.
Even if a node goes down, other nodes can respond and provide data back to the user without issues.
I can confirm that we have experienced six years of zero seconds of downtime.
When I removed all the cables, it failed over within five minutes.
It's quite stable and reliable in general.
I have not experienced any downtime, bugs, or glitches, and it's much better than previous technologies.
Firmware or software updates become effortless with Pure, but with Dell PowerScale (Isilon), we must evaluate or conduct trial runs to ensure that these operations will not harm our customer's system; their software is not adequate.
It should be made more user-friendly in the sense that if I manage it, I should be able to deploy it without having to have a lot of interaction from support.
Regarding Dell PowerScale's AI capabilities, I believe its governance and security are more important for financial or government sectors, so governance and security will require additional upgrades and hardening.
AI capabilities would also increase the security side of the array by easily identifying any bugs or known issues so we can fix them very quickly.
More detailed performance insights and predictive analytics would help resolve issues more proactively.
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.
It's quite expensive for the amount of storage we have.
Cheaper nodes will cost less, while higher performance nodes will be pricier.
Costs align well with what it delivers, making it a fair price for a powerful tool that meets all our needs.
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.
I asked for a new quotation on a server, and it is quite expensive; it is really expensive.
We question that quite often because they have been increased by thirty to thirty-five percent every quarter for unexplained reasons, and that definitely does not go down well with customers.
Dell PowerScale offers high scalability and stability as well, making it a valuable solution for enterprises.
In our AI initiatives, Dell PowerScale (Isilon) plays a significant role in data analysis, data fusion; principally, it is involved in data analysis, data extraction, and statistical analysis.
Single files are limited to four terabytes in our configuration, however, the system can support up to 16 terabytes, so we can scale based on that too.
The faster the back-end storage, the quicker the entire application performs.
I consolidated all the data into a single dashboard accessible via Dell PowerStore Manager, which improves performance and IT infrastructure.
Due to the low latency on IOPS, it helps us with our critical apps that cannot afford delays.
