2.2Memory Configuration and Fault Handling

New dual rank fully-buffered (FB) DIMMs replace the single rank FB-DIMMs. The Sun Blade T6320 server module has 16 connectors (slots) that hold Sun approved, industry standard FB-DIMMs in the following capacities:

■1 Gbyte (maximum of 16 Gbytes)

■2 Gbyte (maximum of 32 Gbytes)

■4 Gbyte (maximum of 64 Gbytes)

■8 Gbyte (maximum of 128 Gbytes)

The Sun Blade T6320 server module performs best if all 16 connectors are populated with 16 identical FB-DIMMs. This configuration also enables the system to continue operating even when a FB-DIMM fails, or if an entire channel fails.

Note – Only dual rank type DIMMs are available as an assemble to order (ATO) option.

2.2.1FB-DIMM Configuration Guidelines

You must follow these guidelines when adding or replacing FB-DIMMs:

■Valid quantities of FB-DIMMs are 4, 8, or 16 (See FIGURE 2-3).

■All FB-DIMMs in the server must be the same capacity.

■All FB-DIMMs in a branch must have the same part number.

Note – FB-DIMMs that run on 1.5V are not supported in this server. An FB-DIMM that runs on 1.5V is sometimes noted with an LV on the part number label. Do not install these FB-DIMMs in this server.

When Upgrading Memory

When adding memory to the server, ensure that you follow all of the guidelines. You might need to move some of the original FB-DIMMs to ensure that all FB-DIMMs in a branch have the same part number.
