Problems solved by technology

At the physical layer, the SAS interface is fully compatible with the SATA interface. The SATA hard disk can be used directly in the SAS environment, but the SAS cannot be directly used in the SATA environment, because the SATA controller cannot control the SAS hard disk.

Abstract

The invention discloses an intelligent switching scheme for onboard SAS and ASTA of a blade server, and relates to the field of computer hardware systems. The scheme mainly includes an SATA controller module for providing an SATA interface, an SAS controller card module for providing an SAS interface, an SAS / SATA Switch module for switching SAS and SATA signals, an SGPIO Switch module for switching SAS and SATA SGPIO signals, and a CPLD module for analyzing the SAS / SATA SGPIO signals and outputting action of HDD LED status. According to the method, through controlling the status of the SAS / SATA_SEL signals, the switching action between the ASA / SATA Switch and the SGPIO Switch can be realized. The method has the benefits that the onboard SAS and SATA can be switched according to the demand of a user, replacement of the main board of a blade is avoided, the switching can be realized on line, the configuration flexibility and the usability of the blade can be improved, and external expansion I / O sources can be saved.

Description

technical field [0001] The present invention relates to the field of computer hardware systems, in particular to a blade server onboard [0002] SAS, SATA intelligent switching solution. Background technique [0003] A blade server is a server unit that can be plugged with multiple card types in a standard-height rack-mounted chassis. It is a high-availability, high-density, and low-cost server platform that is used in special application industries and high-density computing environments. A blade server is like a "blade", and each "blade" is actually a system motherboard. They can start their own operating systems through the "onboard" hard disk, such as Windows NT / 2000, Linux, etc., similar to individual servers. And because each "blade" is hot-swappable, the system can be easily replaced and the maintenance time is reduced to a minimum. [0004] SAS (Serial Attached SCSI) is a new generation of SCSI technology. It is the same as the popular Serial ATA (SATA) hard disk....
