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
8.2
Cisco UCS B-Series enhances performance and efficiency, reducing costs and power usage, surpassing expectations with minimal maintenance and strong returns.
Sentiment score
7.6
Dell PowerEdge Rack Servers offer reliability, cost savings, easy management, and high performance, with flexibility and excellent support enhancing satisfaction.
Additionally, we achieved server consolidation, running multiple services on fewer servers without purchasing new ones, resulting in significant financial benefits.
By not having to worry about it, I would estimate we save two to four hours a week, depending on what's happening, such as if we need to spin up a new server, which would contribute to more time if done the old way.
In my immediate case for antenna analysis, Dell PowerEdge Rack Servers offer a reduction from days of computing to half a day or hours.
The value of uptime to us is critical.
 

Customer Service

Sentiment score
7.3
Users praise Cisco UCS B-Series support for professionalism, quick responses, and reliable 24x7 assistance, with occasional minor delays.
Sentiment score
7.6
Dell PowerEdge Rack Servers support is praised for expertise and resolution speed but sometimes faces delays and communication issues.
Cisco's technical support is highly helpful and responsive.
It has always been scheduled maintenance, which says a lot for a production environment, as we haven't had to call in a trouble ticket for the actual hardware during its entire run.
Typically, the contacts we have on-site are very knowledgeable, they come in within a day and usually have it fixed and taken care of if there are issues.
When we had a power supply failure out of the box, we called support, and they delivered the replacement within four hours as promised.
 

Scalability Issues

Sentiment score
7.9
Cisco UCS B-Series offers robust scalability and flexibility, allowing seamless integration and effortless expansion to meet diverse needs.
Sentiment score
7.7
Dell PowerEdge Rack Servers offer scalable solutions for various sectors, facilitating flexibility and efficient growth despite configuration challenges.
The scalability of Dell PowerEdge Rack Servers is excellent.
Any outages or blackouts are limited to particular servers, not affecting the whole chassis or enclosures.
We bought our product with scaling involved, and we've been scaling it up anytime we've needed more storage.
 

Stability Issues

Sentiment score
8.1
Cisco UCS B-Series is praised for its robust stability and reliability, despite minor challenges in certain operations.
Sentiment score
8.2
Dell PowerEdge Rack Servers offer exceptional reliability and uptime, outpacing alternatives with minimal hardware failures and robust redundancy.
The stability of Cisco UCS B-Series is impeccable, as it has been running smoothly without any need for maintenance.
Over four years, we've had less than 1 percent downtime.
There is a feature to update the server while it is running, so there is no need to restart.
We have truly not had any downtime on the infrastructure at all.
 

Room For Improvement

Cisco UCS B-Series needs improved storage integration, user-friendly management, lower costs, HTML5 transition, and better support for new technologies.
Dell PowerEdge Rack Servers need improvements in performance, scalability, support, security, pricing, efficiency, and integration with virtualization platforms.
Last year, we faced challenges with firmware upgrades, but they were quickly resolved with assistance from Cisco TAC.
We need to know about any upcoming updates so that we can plan accordingly.
The beneficial aspect of that feature was that we could skip the PowerStore and just have the Dell PowerEdge Rack Servers alone, as they also served as storage, which helped us save money.
This forces you to go up to a larger server to get the desired processor, which increases the cost.
 

Setup Cost

Cisco UCS B-Series is costly but offers value and reliability, with discounts available during year-end negotiations.
Dell PowerEdge Rack Server pricing is competitive yet varies, praised for performance and reliability, with bulk purchase discounts available.
The management software, Cisco One, is priced a bit high but still considered reasonable.
They have been stable and running for years without performance downtime or significant disc failures.
Some customers find it cheaper due to contractual agreements, while others find it expensive, especially when scaling up.
The software associated with servers, like VMware subscription licenses, drives costs.
 

Valuable Features

Cisco UCS B-Series excels in scalability, centralized management, ease of deployment, virtualization integration, and offers robust performance and reliability.
Dell PowerEdge Rack Servers are valued for their performance, reliability, cost-effectiveness, and management tools, ideal for diverse applications.
Its administration capabilities provide easy access to performance reports, logs, and utilization data, which are essential for effective server management.
They keep running for at least five to seven years without any issues.
With PowerEdge Servers, I don't need a one-to-one ratio redundancy, which leads to about eighty percent downtime reduction.
One of the valuable features is Active Directory, which helps in managing the network.

Reliable product with efficient automation capabilities
Cisco UCS B-Series manages various processes, including handling payments for over 650,000 growers, running group financials, managing human resources, and operating our main ERP system, SAP. The servers' resilience was particularly impactful. Even during power outages, the servers resumed operations from the last saved point without human intervention. The enhanced processing speed also allowed us to complete tasks that took two days in just one hour. The automation capabilities enhanced efficiency and facilitated integration with our networking components, particularly since we also used Cisco switches. The servers' security was reliable, and formal training on Cisco products made management easier. I rate the product an eight.

Handles workloads and diverse applications efficiently
We have a lot of VMs on Dell PowerEdge Rack Servers. On a single server, we have probably hosted 14 or 15 VMs. Out of these, 8 to 10 are continuously running, and four of them are backup VMs, so it can handle a good workload. For cybersecurity, it is only accessible on the intranet; it is not accessible through the web. We use it for local development purposes, and it is behind our firewall. Its security is strong. We handle a lot of test data for government and confidential customers. It is safe and strong locally. We have not experienced any security issues. Dell PowerEdge Rack Servers have helped to reduce unplanned production downtime if we need to replace a hard disk, instead of completely shutting a server, there is a hot swap feature. It is quite good in that aspect. Usually, for any activity, there is a downtime of about 30 minutes. It has saved a lot of time. We have tried AI workloads for a development environment for a government customer in Singapore. The servers are hosted in Singapore. It is an ML-based engine with AI. It is a government project where data is processed, and we run it on Dell PowerEdge Rack Servers. The benefit of running AI workloads on PowerEdge Servers is that it is easy to allocate memory. The application we are running is memory intensive. It is pretty easy to scale memory and storage.
