Sun Fire V20z and Sun Fire V40z Servers--Differences Between Server Versions |
This document compares the released versions of the Sun Fire V20z and Sun Fire V40z servers. This document includes the following sections:
FRU - Field replaceable units are components that Sun Service must replace .
CRU - Customer replaceable units are components that you can replace.
X-option - an additional (optional) component that you add to a system. X-options might include parts that do not come with a FRU or CRU, such as a CPU heatsink.
Sun Part Number (PN) - a number in the form XXX-XXXX-XX. If the last two digits are greater than -01, Sun updated the part. Abbreviated as XXX-XXXX.
Sun provides updates to documentation, drivers, firmware, and CD-ROM .iso images through the Sun web site. The web site also provides access to technical support and training services. Use the links below to access these Sun services.

Within this document, either the first seven digits in part numbers are listed, or the part number is shown ending in -xx. The full 10-digit part number is not listed to ensure that you always refer to the latest released version of a part.
To determine whether you have the latest version of a Sun product, compare the last two digits of the product's part number on the web site to the part number on your version of the document. A higher number indicates a more current product.
Sun released different versions of the Sun Fire V20z and Sun Fire V40z servers. Hardware and software components are not fully compatible between versions of each server. See TABLE 2 for a list of hardware components and software to support released component configurations. See TABLE 3 for additional information to identify the version of your server.
For more information on the differences between the servers, see Sun Fire V20z and Sun Fire V40z Servers--User Guide, available on the Sun documentation web site.
Note - The chassis FRU PN label is on the front panel of the server, near the DVD-ROM/Diskette Drive assembly. |
Important notes regarding TABLE 2:
380-0979[1] |

380-1206[2] |

Do not mix CPUs of different stepping versions or speeds in a single server. This includes CPUs installed on the optional Sun Fire V40z server CPU card. For more information, see Do Not Mix CPU Stepping Versions.
Due to the power requirements and height restrictions, stepping version "E" CPUs work only in the Sun Fire V20z server with chassis FRU PN 380-1194 and Sun Fire V40z server with chassis FRU PN 380-1206 or 380-1378.
Caution - A new heatsink ships for all stepping version "E" CPUs. Ensure that you do not use an older heatsink on a stepping version "E" CPU. |
TABLE 4 and TABLE 5 list the CPU stepping versions and the associated CPU part numbers. Please refer to the definition for X-option and CRU in Terms Used in This Document
The CPUs available for the Sun Fire V20z and Sun Fire V40z servers have different stepping versions and speeds.
Do not mix CPUs with different stepping versions or speeds in a single server, including CPUs installed on the optional Sun Fire V40z CPU card.
If you order a CPU X-option to add or replace a CPU in your server, order a CPU with the same stepping version and speed. Before ordering, verify the stepping version of your CPU(s) as described in:
Verifying the Stepping Version In a Local Server
Verifying the Stepping Version In a Remote Server
To verify the stepping version of your CPU(s) in a local server with KVM attached:
1. Power on or reboot your server.
A message similar to the following example displays on the screen, and the memory test begins.
This sample shows the output for a Sun Fire V20z server; the output for a Sun Fire V40z server is similar.

2. During the memory test, press the Pause key.
3. Verify the stepping version of the CPUs in the line, similar to one of the following examples:
4. To continue with the reboot, press any key.
To verify the stepping version of your CPU(s) in a remote server:
1. Enable the Serial-Over-Lan (SOL) feature on the SP.
For more information, refer to the "Serial Over LAN" section of the Sun Fire V20z and Sun Fire V40z Servers--Server Management Guide.
2. Start SOL session from a SP command-line interface (CLI) to connect to the platform console remotely.
3. Type the following command.
where baud rate is the value that you set in the BIOS settings; the default baud rate in the BIOS settings is 9600.
For example, if the baud rate in your BIOS settings is set to the default value, you would type:
Note - This command changes the baud-rate value for the SP so that it matches the baud rate in the BIOS settings. It does not change the baud rate in the BIOS settings. |
4. Type the following command:
5. Verify that the correct baud rate displays in the Speed column. Using the example above, the output displays as follows:
6. Activate the SOL session by typing the following command:
7. Create another SP session from the SP prompt.
8. Re-cycle the power on the platform OS by typing the following command:
Note - Before you re-cycle the power, ensure that the platform OS is shut down gracefully, or that the file system has been synchronized using the sync command. |
9. In the SP SOL session that you launched in Step 2, the output of the BIOS CPU step screen displays.

10. During the server's memory self-test, terminate the remote session to pause the screen:
11. Verify the stepping version of the CPUs in the line, similar to one of the following examples:
Memory options vary between server versions for both the Sun Fire V20z and Sun Fire V40z. The memory options are listed in TABLE 6.
