System and method for a reserved memory area shared by all redundant storage controllers
A fibre channel storage area network (SAN) provides virtualized storage space for a number of servers to a number of virtual disks implemented on various virtual redundant array of inexpensive disks (RAID) devices striped across a plurality of physical disk drives. The SAN includes plural controllers and communication paths to allow for fail-safe and fail-over operation. The plural controllers can be loosely-coupled to provide n-way redundancy and have more than one independent channel for communicating with one another. In the event of a failure involving a controller or controller interface, the virtual disks that are accessed via the affected interfaces are re-mapped to another interface in order to continue to provide high data availability. In particular, a common memory storage device is connected to the back-ends of every controller to provide a storage area. In this manner, the common memory storage device can be accessed via operations similar to those a controller already uses to presently access the physical disks which are connected to the back-end of the controllers.

Data replica selector
A method is provided for selecting a replication node from eligible nodes in a network. A multidimensional model is constructed that defines a multidimensional space and includes the eligible nodes, with each of the dimensions of the multidimensional model being a system characteristic. A data availability value is determined for each of the eligible nodes, and a cost of deploying is determined for each of at least two availability strategies to the eligible nodes. At least one of the eligible nodes is selected for replication of data that is stored on a source node in the network. The selecting step includes selecting the eligible node whose: data availability value is determined to be highest among the eligible nodes whose cost of deploying does not exceed a specified maximum, or cost of deploying is determined to be lowest among the eligible nodes whose data availability value does not exceed a specified minimum.

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.

Apparatus and method in a cached raid controller utilizing a solid state backup device for improving data availability time
ActiveUS20050283648A1Improve data availabilityShorten the timeEnergy efficient ICTDigital data processing detailsRAIDControl store
An apparatus for reducing data unavailability time after a loss of main power in a storage controller is described. The controller backs up its volatile memory containing posted-write data to a non-volatile memory upon detecting a loss of main power. The controller continues to provide battery power to the volatile memory to sustain the posted-write data. If the battery is able to supply power to the volatile memory until main power is restored, the controller foregoes restoring the posted-write data to the volatile memory from the non-volatile memory. By not incurring the restore time, which may be substantial if the volatile memory is large since read rates from volatile memories are typically slow, the data unavailability time is reduced. The selective restore feature is user-disableable and also includes a brown-out timer for allowing a user to specify how long to battery-power the volatile memory if the feature is enabled.

Systems and methods for obtaining ultra-high data availability and geographic disaster tolerance

Network data storage systems and methods allow computers reading and writing data at a plurality of data centers separated by, potentially, large distances to replicate data between sites such that the data is protected from failures, including complete Site failures, while not allowing network latency to significantly impede the performance of read or write operations. Continued access to all data is provided even after a single failure of any component of the system or after any complete failure of all equipment located at any single geographic region or any failure that isolates access to any single geographic region. Write data is replicated synchronously from Active Sites, e.g., sites where servers are writing data to storage resources, to Protection Sites located sufficiently close to Active Sites such that network latency will not significantly impact performance, but sufficiently far apart such that a regional disaster is unlikely to affect both sites. Write data is then asynchronously copied to other sites, potentially including one or more Active sites, located at greater distances.
