Dell PowerEdge R340: Specs and Rack Compatibility


At the time of release in 2018, the PowerEdge R340 stood out for its remote management capabilities and ease of use for entry level users. Along with a balanced spec sheet, the iDRAC9 controller allows users to view and manage important information and configurations in your server all from a browser. 

This model is still available on Dell’s website, with the lowest spec starting at $669 and the higher tier around $2749. Of course, these can be customized further on Dell’s website. Possibly because of how new this server is, or that customers are satisfied, the aftermarket is not thriving at this point in time.
