Kealia designed Magnum, a high capacity InfiniBand switch; Galaxy, a range of blade servers based on AMD's Opteron microprocessor; and Thumper, an enterprise grade network attached storage system.
In 2009, IBM announced a December 2009 release date for their DB2 pureScale offering, a shared-disk clustering scheme (inspired by parallel sysplex for DB2 z/OS) that uses a cluster of IBM System p servers (POWER6/7) communicating with each other over an InfiniBand interconnect.
The glusterfs client process, which connects to servers with a custom protocol over TCP/IP, InfiniBand or Sockets Direct Protocol, creates composite virtual volumes from multiple remote servers using stackable translators.
His work with protected user-level communication has contributed significantly to the Remote Direct Memory Access (RDMA) mechanism and Virtual Interface Architecture standard and Infiniband standard, which are the communication mechanism for the Direct Access File System (DAFS).
