Administrator Queue Operational Queue Queue Types
Management of the controller functionalities Initialized using the controller register set One administrator IQ One administrator OQ Highest priority Create operational queues Operational Queue SCSI operations Compact IU Extended IU X:Y ratio of IQs and OQs Initiator mode and target mode Configurable: Priority Queue element size Number of queue elements T10/11-126r0 SOP Administrator Queue

Initializing Administrator Queue
Host passes the host physical addresses of Administrator IQ and OQ buffers Host passes the host physical addresses of Administrator IQ CI and OQ PI IQ CI and OQ PI are in host memory Controller returns the controller offset addresses of Administrator IQ PI and OQ CI IQ PI and OQ CI are controller soft registers T10/11-126r0 SOP Administrator Queue

Creation of Operational Queues and Administrator Function
Operational queues are created using the Administrator Function submitted to the Administrator IQ Response is returned in the Administrator OQ Administrator function also includes other administrator function: Get controller capabilities Get controller statistics and logs Etc T10/11-126r0 SOP Administrator Queue

Administrator Functions Part 2 of 2
Req Description GET PROPERTY OPERATIONAL OQ M Get properties of the inbound operational queue, i.e. queue element size and number of elements, association with MSI-X vector, max chaining, interrupt coelescing, etc SET PROPERTY OPERATIONAL OQ O Set properties of the inbound operational queue, i.e. , association with MSI-X vector, maximum chaining, interrupt coalescing, etc FREEZE OPERATIONAL IQ Temporarily freeze the corresponding inbound operational queue UNFREEZE OPERATIONAL IQ Unfreeze the corresponding inbound operational queue GET CONTROLLER STATISTICS Get controller statistics, i.e. performance, error statistics, etc. SET EVENT LOG Set the location and size of event log in host processor memory space GET CONTROLLER LOG Get controller vendor specific internal log SPIN UP CONTROLLER POWER Staggered spin up controller power consumption T10/11-126r0 SOP Administrator Queue
