Cache management for sequential io operations

A storage system comprising:

• a plurality of physical storage devices for storing data;
• a plurality of physically discrete storage processing nodes, each storage processing node including a compute component for executing logic to process IO operations and a memory, the memory including a cache segment for use as part of a shared cache distributed across the plurality of processing nodes, wherein shared cache includes a plurality of cache slots,
• and wherein the memory of one or more of the plurality of physically discrete storage processing nodes collectively has code thereon that, when executed, performs a method including:
• receiving a first IO operation at a first of the plurality of storage processing nodes;
• determining that at least a first quantity of next IO operations that will be received from a host system will be sequential IO operations from the host system;
• determining a next storage processing node of the plurality of storage processing nodes that will receive IO operations from the host system;
• and
• managing the shared cache to store data for at least a subset of the first quantity of next IO operations in a first cache slot located within the next storage processing node.

For a storage system including a plurality of physical storage devices for storing data and a plurality of physically discrete storage processing nodes, each storage processing node including a compute component for executing logic to process IO operations and a memory, the memory including a cache segment for use as part of a shared cache distributed across the plurality of processing nodes, wherein the shared cache includes a plurality of cache slots, computer-readable media having software stored thereon, the software comprising:

• executable code that controls receiving a first IO operation at a first of the plurality of storage processing nodes;
• executable code that determines that at least a first quantity of next IO operations that will be received from a host system will be a sequential IO operation from the host system;
• executable code that determines a next storage processing node of the plurality of storage processing nodes that will receive IO operations from the host system;
• and
• executable code that manages the shared cache to store data for at least a subset of the first quantity of next IO operations in a first cache slot located within the next storage processing node.
