Tattoo Power Components

Computer tattoo power supply is a closed independent component installed in the host box. Its function is to convert AC power through a switch tattoo power transformer to stable DC power of 5V, -5V,+12V, -12V,+3.3V, etc., to supply system components such as system boards, floppy disks, hard drives, and various adapter expansion cards inside the host box. Simply put, one tattoo power supply is broken and another backup tattoo power supply replaces it. Hardware availability can be enhanced by providing battery backup for nodes and disks. The uninterruptible tattoo power supply (UPS) supported by HP, such as HP PowerTrust, can prevent instant power failure. The connection between the disk and the power supply circuit should be such that the mirrored copies are connected to different tattoo power sources. The root disk and its corresponding nodes should be powered by the same tattoo power circuit. In particular, the cluster lock disk (used as an arbiter when restructuring the cluster) should have redundant tattoo power supplies, or it can be powered by tattoo power supplies outside of the nodes in the cluster. Your HP representative can provide detailed information about the tattoo power, disk, and LAN hardware layout of the cluster. Currently, many disk arrays and other rack mounted systems contain multiple tattoo power inputs, which should be deployed as separate tattoo power inputs on the device connected to independent circuit devices with two or three tattoo power inputs. This way, in general, as long as there is no more than one faulty circuit, the system can continue to operate normally. Therefore, if all hardware in the cluster has 2 or 3 tattoo power inputs, it is required to have at least three independent circuits to ensure that there are no single points of failure in the cluster's circuit design.
