Connecting the motherboard power connector motherboard not only needs power, but also to the CPU, graphics, PCI cards and other devices to power, so the motherboard to power the connector is the largest. The connector is made up of 20 power cords,

The server Sun Fire B1600 Blade chassis is a 16-socket 3U chassis that installs two integrated gigabit Ethernet switches, two system controllers, and two power supplies. This smart frame is highly reliable and has a server density of five times times the typical single processor 1U server. The horizontally scalable Sun Fire B1600 blades are designed for throughpu

the management of one server, which will greatly reduce the IT management personnel cost, simplify IT infrastructure, and improve management efficiency. For cabling designers, the biggest advantage of blade servers is that each server chassis is 3U ~ In 7U), only one set of network interfaces is available. Of course, one set of network interfaces in Hot Backup status may also be available. Assuming that a

Specifications and features of the PXI busBased on PCI electrical specification, curiosity PCI mechanical specification, and VXI plug-and-play specification, the PXI bus specification expands 13 local buses: trigger signal line, clock signal line, formed by simulating the signal line.

expansion slots. in addition, the heat dissipation performance has become a very important factor. At this time, the power of each manufacturer is shown here. The disadvantage is the need for organic cabinets and other equipment, which is mostly used by enterprises with large server usage. (3) blade servers: This is a more space-saving product than rack-mounted servers. the main structure is a large main chassis. Many cards can be inserted inside, an

GW mst-d Data Service multiplexing equipment: Independent small chassis, the use of 1 standard E1 channels in the free time slot to provide users with v.24 interface, v.35 interface business, can be widely used in telecommunications data services, electricity, banks and other terminals of the transmission line, mainly for the transmission of monitoring information.

Tower-Type ServerTower server is generally seen the most, its shape and structure are similar to the ordinary PC, just a little larger, the size of its dimensions do not have a unified standard.The tower server's motherboard is strong, the socket is also many, and the tower server inside the chassis often reserved a lot of space for the hard disk, power supply and other redundant expansion. This server eliminates the need for additional equipment, doe

Some people say that the host is nothing but a few pieces of hardware, but still quite exquisite. The author believes that DIY installed first need to look at the use of demand, after the determination of the need to choose reasonable hardware, generally speaking, CPU, motherboard, video card, memory, hard disk, power supply, chassis this order, but if this one encountered some x factors (unknown, uncertain factors) how to determine it? For example, t

-- Prio63. Prio56Each Task in the ready state can have the corresponding position 1 in osrdytbl[] based on its priority value. For example, if a Task with ready has a priority value of 4, you need to set osrdytbl[0] |= bit_4.Osrdygrp Os_ext Os_prio osrdygrp; /* Ready List Group Each bit of the OSRDYGRP represents the group of each priority in osrdytbl[]. For example, the Prio5 Task is in the ready state and it belongs to Osrdytbl[0],

real-time operating system that divides 64 priorities (UC/OS-II), each with a different priority, and always chooses the highest priority task in the ready state in the event of scheduling. In order to quickly select a ready task in a limited time, UC/OS-II established a two-level readiness table, each task (i.e. each priority) occupies a bit in the first-level readiness table OSRDYTBL, and each 8 bits is formed into a osrdygrp. This first finds the group of the highest priority task from OSRDY
