Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
6.6
Dell PowerStore offers positive ROI through cost savings, enhanced performance, efficient deduplication, and valued lifecycle and feature enhancements.
Sentiment score
8.1
Teradata improved speed, efficiency, and customer satisfaction, achieving significant ROI, enhanced analytics, and reduced staffing needs for users.
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.
We have realized a return on investment, with a reduction of staff from 27 to eight, and our current return on investment is approximately 14%.
 

Customer Service

Sentiment score
6.2
Dell PowerStore support is responsive, professional, and reliable, though some users note language barriers and response delays.
Sentiment score
7.1
Teradata support is highly rated for professionalism and resources, though some users note slow response times and technical support challenges.
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.
The customer support for Teradata has been great.
Customer support is very good, rated eight out of ten under our essential agreement.
The technical support from Teradata is quite advanced.
 

Scalability Issues

Sentiment score
7.1
Dell PowerStore offers scalable solutions with NVMe technology, supporting storage growth but may have cost concerns for some users.
Sentiment score
7.4
Teradata offers exceptional scalability and speed, though some users face challenges with hardware requirements and scaling involvement.
The solution's scalability is a ten out of ten.
The customer likely exceeds 20,000 users globally.
You can create as many tools as needed, providing scalability based on the use case.
This expansion can occur without incurring downtime or taking systems offline.
Scalability is complex as you need to purchase a license and coordinate with Teradata for additional disk space and CPU.
Teradata's scalability is great; it's been awesome.
 

Stability Issues

Sentiment score
7.6
Dell PowerStore is praised for reliability and performance, despite minor software issues, earning high satisfaction ratings from users.
Sentiment score
8.3
Teradata is stable and reliable, with excellent uptime, minimal downtime, and seamless upgrades, though large dataset issues occur.
When I removed all the cables, it failed over within five minutes.
There are no bugs or glitches and it doesn't crash or freeze.
I would rate the stability of Dell PowerStore as ten out of ten.
I find the stability to be almost a ten out of ten.
The workload management and software maturity provide a reliable system.
 

Room For Improvement

Dell PowerStore users seek improved integration, enhanced functionality, better pricing, user interface, security, support, and enterprise-ready features.
Teradata requires cost-effective improvements in cloud integration, scalability, UI, data processing, analytics, compatibility, support, and pricing.
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.
Unlike SQL and Oracle, which have in-built replication capabilities, we don't have similar functionality with Teradata.
The most challenging aspect is finding Teradata resources, so we are focusing on internal training and looking for more Teradata experts.
 

Setup Cost

Dell PowerStore pricing is high but justified by features, competitive licensing, scalability, and overall market alignment.
Teradata offers advanced features and cloud flexibility, though enterprises need careful cost-benefit analysis for its premium pricing.
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.
Teradata is much more expensive than SQL, which is well-performed and cheaper.
Initially, it may seem expensive compared to similar cloud databases, however, it offers significant value in performance, stability, and overall output once in use.
We spent roughly $295,000 on setup costs.
 

Valuable Features

Dell PowerStore offers flexibility, performance, ease of use, data protection, and cost savings with reliable architecture and machine learning.
Teradata excels in fast query processing, scalability, robust security, and cross-platform integration, enhancing performance and reducing administrative effort.
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.
Teradata's security helps our organization meet compliance requirements such as GDPR and IFRS, and it is particularly essential for revenue contracting or revenue recognition.
The data mover is valuable over the last two years as it allows us to achieve data replication to our disaster recovery systems.

Eoin O’Brien - PeerSpot reviewer
Improves cost efficiency and significantly while boosting workload performance
We have realized several benefits from using Dell PowerStore; we migrated to the current Dell PowerStore models from tiered storage, and now we're using all flash. The dedupe and compression has been a big benefit for us versus the old storage that it was running, and we've seen the performance of all flash for our storage services. My company finds particular features within Dell PowerStore valuable, primarily the cost benefits for the performance that we get out of the platform. We've definitely seen the benefit on that side of it, including the cost per terabyte, and the support from Dell has been excellent as well. We haven't had any issues with it, so it's been very reliable as a platform for us. The performance metrics I use to measure success with Dell PowerStore are all IOPS and throughput. We are not using it with AI workloads on Dell PowerStore, so it's primarily just customers running IaaS, however, it is important that it's reliable and performs well, and we get that from Dell PowerStore. Dell PowerStore has supported growth and operational success for my business; a key driver at the moment is consolidation, and the dedupe and compression ratios allow us to standardize on a single platform. This has helped improve our operational metrics and overall operations, as we now have only one vendor to support and one set of storage arrays to manage. We have a very clear path into support and escalation if there is an issue, and we are not dealing with multiple vendors.
Kirk Robinson - PeerSpot reviewer
Has improved data quality, optimized reporting processes, and enabled predictive insights across business units
The limitation we encountered was related to speed, prompting us to increase our AWS cloud thresholds and benchmarks on the servers, adding more throughput. We have been testing that, but speed remains one of our key issues. The integration has been awesome because of the platforms and their usage, and usability is great. The most challenging aspect is finding Teradata resources, so we are focusing on internal training and looking for more Teradata experts. If Teradata could provide a list of certified experts, that would be fantastic. I rated Teradata a nine because the main area for improvement is the bandwidth of resources that could assist us in applying to our projects, specifically more certified and expert resources. The market share of Teradata professionals is limited, creating an issue for us.
