Identifying the series of your Dell EMC PowerEdge
servers
The PowerEdge series of servers from Dell EMC are divided into different categories based on their configuration. They are
referred as YX2X, YX3X, YX4X, YX4XX, or YX5XX series of servers. The structure of the naming convention is described below:
The letter Y denotes the character in the server model number. The character denotes the form factor of the server. The form
factors are listed below:
● C- Cloud
● F- Flexible
● M or MX- Modular
● R- Rack
● T- Tower
The letter X denotes the numbers in the server model number. The number denotes multiple characteristics about the server.
They are listed as follows:.
● The first digit (X) denotes the value stream or class of the server.
○ 1-5—iDRAC basic
○ 6-9—iDRAC Express
● The second digit denotes the series of the server. It is retained in the server naming convention and does not replace the
letter X.
○ 0—series 10
○ 1—series 11
○ 2—series 12
○ 3—series 13
○ 4—series 14
○ 5—series 15
● The last digit (X) always denotes the make of the processor as described below:
○ 0-Intel
○ 5-AMD
NOTE:
For servers that use an AMD processor, the model number is made up of four digits instead of three. The third digit
(X) denotes the number of processor sockets that the series of server supports.
