摘要： A storage controller has a capacitor pack for storing energy to supply during a main power loss, a temperature sensor that senses the capacitor pack temperature, and a CPU, which repeatedly: receives the temperature during an interval over which the capacitor pack is operated, determines a lifetime over which the capacitor pack would have a capacity to store at least a predetermined amount of energy if operated at the temperature during the lifetime, normalizes the interval by a ratio of a warranted lifetime of the capacitor pack relative to the determined lifetime, and adds the normalized interval to an accumulated normalized running time. The operating voltage of the capacitor pack may also sampled and used to determine the lifetime. The predetermined amount of energy may be for backing up a volatile write cache to a non-volatile memory in response to the loss of main power.

摘要： A storage controller has a capacitor pack for storing energy to supply power during a main power loss, a temperature sensor that senses the capacitor pack temperature, and a CPU, which detects that the temperature of the capacitor pack has risen above a predetermined threshold while operating at a first voltage value and determines whether a projected lifetime of the capacitor pack is less than the warranted lifetime. If the projected lifetime is less than the warranted lifetime, the CPU reduces the operating voltage of the capacitor pack to a second value, in order to increase the capacitor pack lifetime. In one embodiment, the CPU reduces the voltage if an accumulated normalized running time of the capacitor pack is greater than an accumulated calendar running time. In another embodiment, the CPU reduces the voltage if a percentage capacitance drop of the capacitor pack is greater than a calendar percentage capacitance drop.

摘要： A high data availability write-caching storage controller has a volatile memory with a write cache for caching write cache data, a non-volatile memory, a capacitor pack for supplying power for backing up the write cache to the non-volatile memory in response to a loss of main power, and a CPU that determines whether reducing an operating voltage of the capacitor pack to a new value would cause the capacitor pack to be storing less energy than required for backing up the current size write cache to the non-volatile memory. If so, the CPU reduces the size of the write cache prior to reducing the operating voltage. The CPU estimates the capacity of the capacitor pack to store the required energy based on a history of operational temperature and voltage readings of the capacitor pack, such as on an accumulated normalized running time and warranted lifetime of the capacitor pack.

摘要： A write-caching RAID controller is disclosed. The controller includes a CPU that manages transfers of posted-write data from host computers to a volatile memory and transfers of the posted-write data from the volatile memory to storage devices when a main power source is supplying power to the RAID controller. A memory controller flushes the posted-write data from the volatile memory to the non-volatile memory when main power fails, during which time capacitors provide power to the memory controller, volatile memory, and non-volatile memory, but not to the CPU, in order to reduce the energy storage requirements of the capacitors. During main power provision, the CPU programs the memory controller with information needed to perform the flush operation, such as the location and size of the posted-write data in the volatile memory and various flush operation characteristics.

摘要： A network storage controller for transferring data between a host computer and a storage device, such as a redundant array of inexpensive disks (RAID), is disclosed. The network storage controller includes at least one channel interface module which is adapted to be connected to the host computer and storage device. The channel interface module is connected to a passive backplane, and selectively transfers data between the host computer and storage device and the passive backplane. The network storage controller also includes at least one controller memory module, attached to the passive backplane. The controller memory module communicates with the channel interface module via the passive backplane, and processes and temporarily stores data received from the host computer or storage device. In applications where redundancy is required, at least two controller memory modules and at least two channel interface modules are used. The controller memory modules may mirror data between one another using the passive backplane and a shared communication path on the channel interface modules, thereby substantially avoiding the use of host or disk channels to mirror data. The channel interface modules are operable to selectively connect the host computer or storage device to one or more controller memory modules. The controller memory modules may include a DMA engine to facilitate the transfer of mirrored data.

摘要： A server blade includes a printed circuit board (PCB), including a connector for connecting the blade to a backplane comprising a local bus, and a removal mechanism for use by a person to disconnect the connector from the backplane for removal of the blade from a chassis while the chassis is powered up. The server blade also includes an I/O link and a server, each affixed on the PCB. The server transmits packets on the I/O link to a storage controller enclosed in the chassis. The packets include commands to transfer data to at least one storage device controlled by the storage controller. A portion of the storage controller, affixed on the PCB, receives the packets from the server on the I/O link, and forwards the commands on the backplane local bus to another portion of the storage controller affixed on a separate PCB enclosed in the chassis.
