A rack server, or rack-mounted server, is any server that is built specifically to be mounted within a server rack. Rack servers help enterprise or data center build large services groups with many server racks. Rack servers also save place and cost.
There are many brands of rack server in the market. Which to buy?
In this post, I will share you a comparison chart of top brands, Dell R740 vs. HPE DL380 G10 vs. Lenovo SR650. Hope this help!
