Intel® Server System SR1550AL Product 

The Intel

®

 Server Chassis SR1550 is a 1U server chassis that is designed to support the Intel

®

 

Server Board S5000PAL and Intel

®

 Server Board S5000XAL. Together, the integrated products 

make up the Intel

®

 Server System SR1550AL. The server boards and chassis have feature sets 

designed to support the high-density server market. This chapter provides a high-level overview 
of the system features. Greater detail for each major system component or feature is provided in 
the following chapters. 

The Intel

®

 Server System SR1550AL represents a major departure from previous generation 

products. Most cables have been removed from the system and replaced by a series of board-
to-board interconnects.  Using board-to-board interconnects simplifies platform integration and 
improves airflow for more reliable cooling. 

A second significant change from the previous generation of products is the introduction of the 
mid-plane system board.  There are two options for this board: The first option is a cable-less 
“active” mid-plane which includes an onboard SAS controller providing SAS / SAS RAID support.  
The second option is a “passive” mid-plane which provides cabled point-to-point interconnects 
to support either the onboard SATA ports of the server board, or to a SATA or SAS PCI add-in 
card.
