Redundant array of independent servers

An integrated atomic server (IAS) system, comprising:

• a local array of drives configured to store a plurality of data blocks and at least one configuration data structure comprising at least one mapping function for at least one logical block address;
• and
• a first controller configured to:
• perform, with a plurality of IAS systems, a plurality of operations to maintain distributed redundancy across the plurality of IAS systems, wherein performance of at least two of the plurality of operations occurs in parallel, the plurality of operations comprising at least:
• transmitting, via a high-speed interconnect using an integrated switch, a first sequence of operations to a second controller of a second IAS system to cause the second controller to execute the first sequence of operations on a second plurality of data blocks;
• and
• transmitting, in parallel with transmission of the first sequence of operations via the high-speed interconnect using the integrated switch, a second sequence of operations to a third controller of a third IAS system to cause the third controller to execute the second sequence of operations on a third plurality of data blocks;
• wherein the IAS system, the second IAS system, and the third IAS system share a distributed data mapping of the plurality of data blocks of the IAS system, the second plurality of data blocks, and the third plurality of data blocks, and wherein the IAS system, the second IAS system, and the third IAS system share a distributed parity mapping of a plurality of parity blocks;
• wherein each IAS system of the plurality of IAS systems corresponds to a hot-swappable module plugged into a slot within a chassis and interface via the integrated switch using a corresponding controller.
