Featured Reviews

Dibyendu Das - PeerSpot reviewer
Director at a tech company with 11-50 employees
Ultra-low latency networking has delivered reliable video workflows and critical operations
The support of Arista Networks Platform is quite complex; it is not very easy to configure. It needs a lot of network expertise for token sheddings and different kinds of configurations. It is very difficult to configure because Arista Networks Platform does not have a flexible GUI like Huawei or Netgear; everything is a very CLI kind of mainframe architecture. Scalability at every single step has a huge upgrade cost which is required for port mapping, connectivity, and transceivers certified by Arista Networks Platform, then the fabric upgrades from a software firmware level. Arista Networks Platform should improve commercial aspects to be affordable. There is no path for growth with a perfect score because the focus is more on reducing costs globally.

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.
