A hiccup management scheme for use within a storage system can maintain low latency on client I/O when a storage device is temporarily unavailable. In some embodiments, a storage using uses double parity data protection can tolerate concurrent hiccups by up to two storage devices within a storage array.

Hiccup management in a storage array

Described herein are embodiments of a process that can be used to balance the allocation of primary memory between different types of information. In some embodiments, the memory allocation is balanced dynamically based on observed I/O patterns. Related system embodiments are also described.

Memory allocation balancing for storage systems

Described herein are several embodiments of systems and processes to decrease startup time for subsystems of a storage system. According to some embodiments, subsystem memory is allocated using memory-mapped files.
