This forces you to go up to a larger server to get the desired processor, which increases the cost.

Network Engineer at Castlenet Consulting Limited
Cloud-managed access points have simplified deployments and saved significant installation time
I have been using Arista Networks Platform for three years now. Arista Networks Platform is easy to use, and after deployment of the access points, the dashboard makes it easy and convenient to use with easy navigation, which is excellent. The access points on Arista Networks Platform operate in the cloud through the GUI where you operate the access points and perform all configurations for the access points on the platform. In terms of performance with Arista Networks Platform, I would give it a perfect score as it has not failed me before. The only time I had an issue with Arista was when the access point went into rest mode, probably after a power outage in an infrastructure. After contacting Arista and attending an Arista program, I was guided through a solution via the Arista GUI, which I implemented, and since then, the performance has been excellent. In terms of security, I have no issues with Arista; it performs really well in terms of security. Arista Networks Platform is very convenient overall. Arista Networks Platform has really boosted our organization to the extent that our organization does not want to think about any other platform except Arista in terms of access points and switches. We are just diving into the switch area. In terms of time saved with Arista Networks Platform, the access points are easy to install and the switches are easy to install. I can install seven or eight access points in less than two hours. It is really easy to install and time-saving. In terms of cost, I think it is cost-efficient compared to others in the same field.

Supports flexible hosting needs through seamless upgradability and strong monitoring capabilities
The most valuable features of Dell PowerEdge R-Series for me are the feature richness and the upgradability. I really love the way that it is so dynamically applicable for every situation, and they manage to have an all-in-one solution for every single situation. Dell PowerEdge has supported the growth and operational success of my company through its great compute power and price-to-performance ratio. Every time Dell is at the top of its game for us, and there is just no other brand for us that is able to reach that kind of price-to-performance ratio. Dell PowerEdge R-Series has features that specifically cater to the needs of my small company, such as iDRAC. The iDRAC system is a complete feature set for managing servers and hardware technically and monitoring-wise. It really fits in our system and our ecosystem, and monitoring-wise, it is excellent. They have all these sensors available via different protocols and end points, which I love, and the ability to manage and control everything via the iDRAC interface is just a welcome bonus. In our use case, Dell PowerEdge R-Series is very flexible. It is another computer which helps a lot because of the durability over time. They keep running, making scalability for getting more of those resources in our environment so easy.
