Field of the Invention The present invention relates to a computer system, particularly to a state light number control device for a blade cutter. [Prior Art] The blade server system is a common server system which is composed of a plurality of blade server blades. A blade servo-chip system integrates the hardware of a server system such as a processor, a memory, and a hard disk drive into a single motherboard. Each blade server unit shares resources such as chassis, power supply, keyboard, display, and mouse. The blade server blade can be divided into a main blade servo blade (h〇st Made) and an extended blade blade (expansion blade), wherein the extended blade server blade can be combined with the extended blade server blade and inserted into the chassis. Provides extended functionality to the main blade server slice. The combination mode of the main blade servo chip and the extended blade server can be divided into two types, one is a series mode and the other is a non-serial mode.刀 Blades are generally equipped with storage devices such as hot-swappable hard drives or fixed hard drives. If a hot-swappable hard disk drive is used, and the hard disk drive LED status light is generally installed, if a fixed hard disk drive is used, because the fixed hard disk drive is fixed in the blade server, it is not required to be equipped with a led device. Status light. When using a hot-swappable hard disk drive, the blade servo servo hard disk controller generally controls the action of the hot-swap hard disk drive and can detect the status of the hard disk drive, and provides a hot-swappable hard disk drive. A message that is working or malfunctioning. Knife 131616.doc 200949546 The storage enclosure processor of the front feeding device reads the status of the hard disk drive and controls the LED status light of the hot-swappable hard disk drive according to the message. The combination mode of the main blade server chip and the extended blade server chip can be divided into two types: an in-line mode (Annexing Mode) and a non-series mode (Non Annexing Mode). When the main blade server is hot swappable and the extended blade server is in series mode, the disk hard controller of the main blade server will be disabled, so the storage box is disabled.

Therefore, in the blade servo technology, the LED status lights of the hot-swappable hard disk drive of the main blade servo chip and the extended blade servo chip can be correctly displayed in various states. This is an important research and development direction of the industry. SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a blade server system, a blade server blade, and a method therefor.

[Embodiment] FIG. 1 is a system block diagram showing a blade server according to an embodiment of the present invention. In the blade servo system 丨60, a plurality of blade server segments i68 are inserted into the central circuit board 156. In the slot (not shown), a server system can be plugged into a plurality of (for example, six or fourteen) blade servers. All blade server blades share resources such as chassis, power supplies, fans, switches, mice, keyboards, and monitors, and all blade servers are controlled through a management module ® 176. Alternatively, the function of the blade server segment 168a can be expanded by connecting the extended blade server blade 168b to a busbar, connector, or interface busbar (not shown) of a blade server blade. The blade servo blade 168a is specifically referred to herein as a primary blade servo blade, and the primary blade servo blade 168& and the blade servo blade 168 are substantially identical in function and appearance.

The main blade server piece 168a includes a first group of storage devices, which may be hot-swappable hard disks 220 and 616'. Each of the hot-swap hard disks 220, 616 has two LED status lights, respectively, which are displayed. The status of the pull-out hard disks 220 and 616 is only 131616.doc 200949546. A set of LED status lights 232 and 236 for the hot-swappable hard disk 220 is shown. The main blade server piece 168a also includes a first storage. The device controller 212, wherein the hot-swap hard disks 220 and 616 are coupled to the first storage device controller 212; the first storage chassis processor 204' is coupled to the first storage device controller 212; A baseboard management controller 208 coupled to the first storage enclosure processor 204; a group OR gate comprising: a first OR gate 224 having a first input 276 coupled to the first storage enclosure processor 204, a second input 280 coupled to the substrate tube controller 208, an output 284 coupled to the first status light 232, and a second OR gate 228 having a first input 288 coupled to the first storage chassis processor 204, the second input 292 is coupled to the substrate Management controller 208, an output coupled to the second light state 236,296. Referring also to Figure 1, the baseboard management controller 208 cooperates with the management module 176 in the blade server system 160 to control the blade server blade 168a. The storage chassis processor 204 can be a Programmable System-on-Chip (PSoC)' used to manage the ® environment of the chassis. The first storage device controller 212 can be a hard disk drive control chip for controlling the operation of the hard disk drive. The hot-swappable hard disks 220 and 616 can be SAS hard disks, SATA hard disks, or solid state hard disks.
