1. A computing platform comprising: a compute node comprising: multiple processing cores for executing an application; and multiple vector-based cache buffers, wherein data from I/O calls from execution of the application are aggregated in the cache buffers according to a plurality of parity groups; a storage server cluster in communication with the compute node, wherein the storage server cluster comprises a plurality of I/O servers, wherein each I/O server is connected to and controls a plurality of disk drive data storage systems, wherein: data in the cache buffers are transmitted from the compute node to at least one of the I/O server servers of the storage server cluster and stored in queues on the at least I/O server; and the disk drives data storage systems write the data from the queues sequentially in data fragments to disks of the disk drive data storage systems such that data fragments of differing parity groups are not written on the same disk.
