Is converged infrastructure the future of data centers?

reality is that they cannot be restarted immediately. For example, the concept of integrated controller in SDN is still a promise that can be fulfilled in the future ." New bottled old wine? If the integrated infrastructure makes you feel a bit like utility computing, grid computing, shared servers, SOA or cloud computing, then you feel right. The difference between today's integrated infrastructure is that it is borderless, pre-configured, pre-optimized, and usually preloads the applications r

Wide-range Voltage regulator automatically selects operating mode

ic1shut down. as the output voltage increases, the voltage differential across r7decreases, and, when it Dr OPS below 0.9V, Q1 ' s collector current decreases, lowering the feedback voltage applied to ic1and switching it on. The boost regulator ' s output voltage increases, and the Q1-ic1feedback loop regulates the collector-emitter voltage Differential across Q2to a constant 3V for all outputs exceeding 8V. If IC2 ' s output goes to ground, cutting off q3and forcing Q2into saturation, the feed

Constant Current Source Design

The output current of the constant current source is constant. If this circuit is applied to some input fields, the input device can be effectively protected. For example, this circuit is used in rs422 communication to effectively protect the communication. It can protect against overvoltage within a certain voltage range. The following reference is a constant current source analysis. The constant current source is the current source with the output current unchanged, and the ideal constant cur

How the transistor works-the most common method I have ever seen

digital circuit, the valve is in the on or off two states. When not working, the valve is completely closed and there is no power consumption. The descriptions of saturated areas and cutoff areas are a bit problematic, but you certainly know these principles. Let me modify it by referencing your metaphor: Closing area: it should be that the small valve is not enough to open and cannot open the valve. This is the closing area. Saturation zone: it should be that the small valve is too large to o

Proper configuration of PCB decoupling Capacitor

Original article address: PCB decoupling capacitor reasonable configuration Author: ker11f I. Category of decoupling capacitors in PCB The decoupling capacitor can be used for energy storage when the operating voltage of the integrated chip or circuit board is compensated. It can be divided into three types: integral, partial, and inter-board. The overall decoupling capacitor is also called a bypass capacitor. It operates in a low frequency ( Local decoupling capacitors have two functions. First

SMI-S expect more

to claiming that its tape library can be managed in the SMI-S-compliant console, it also provides APIs (application interfaces ), other vendors can use these APIs to manage the ADIC tape library. Currently, EMC uses this method: In the same EMC San topology, the ADIC tape library is displayed in real time together with other San components, however, the specific management work is still implemented through

The importance of 0 ohm resistance, PCB engineering must know

1 : no function is provided in the circuit. It is only for convenience of debugging or Compatibility Design on the PCB. 2 : Jumper can be used. If a line is not used, do not paste the resistor directly (without affecting the appearance) 3 : when the matching circuit parameters are uncertain, use 0 ohm instead. during actual debugging, determine the parameters, then, it is replaced by a component of a specific value. 4. when you want to test the current consumption of some circuits, you ca

Challenges for terminal antenna engineers under multiple wireless standards

With the popularization of 3G technology and the development of wireless standards and technologies such as LTE, NFC, Bluetooth 4.0, cmms B, and MIMO, mobile Terminals need to integrate multi-band main antennas (supporting 2g, 3G, LTE and other multi-standard), as well as GPS, BT, WiFi, NFC, wireless charging and other antennas. As a result, terminal antenna engineers are facing huge challenges: Antenna size -The cell phone size is getting smaller and smaller.-The 'clear' of the antenna is getti

Section 3 multilayer PCB cascade structure

Before designing a multilayer PCB, the designer must first determine the structure of the PCB based on the circuit size, circuit board size, and EMC requirements, that is, it is decided to adopt a 4-layer, 6-layer, or more layers of the circuit board. After determining the number of layers, determine the placement location of the inner electrical layer and how different signals are distributed on these layers. This is the choice of multilayer PCB stac

", which forms multiple links, if a disk is selected from the storage on the host, many disks may be released on the host, which will make the operator unable to choose which disk to operate. To avoid this cumbersome disk link, the multi-path software is used to aggregate multiple paths. It facilitates disk management and load balancing. If one link is disconnected, other links are still available, which will not affect disk access. Several multi-path software: (1) IBM host and IBM storage: RDA
