2U rack-type Server Shopping guide pay attention to performance and scalability

Server main organic and tower two specifications, rack-type server is the adoption of international standards of 19-inch rack-type design, the overall volume of the server also has a very good performance, it can be very convenient to install in the standard rack or cabinet, This is also why many users who need to host or bulk deploy servers buy rack-and-rack servers. However, due to the size of the rack-type server itself, its scalability performance has been not very good, especially 1U rack server, in addition to the basic CPU, memory has a certain degree of expansion, other I/O expansion is very limited, but this is not to say that all the rack-type server scalability is not good.


　　


in all rack-type servers, I think 2U rack server is a very good product, the first is 2U rack-type server occupies only 1 time times the size of 1U, for the bulk of the deployment does not have a particularly large impact; Secondly, in terms of expansion capability, with the increase of chassis volume, internal i/ o The expansion of the device has been greatly improved, for example, with enough I/O expansion slots, more hard drive bays, and so on, the expansion capacity of the increase is more than the negative impact of the increase in volume; At the same time, due to the increase in the internal space, the server cooling capacity has been very good, but also greatly improved the server and stability Finally, in terms of price, it still retains its due cost-performance, and better performance than other rack-type servers.





2U Rack Server The most extensive hosting and bulk deployment Server users the best choice, and the market on the 2U server is also one of the most server products, the following I will show you the recent popular 2U rack-type server products.
