StorNext 3 .5 Install ation Guid e 142 Appendix D D Quality of Service Guide This appendix describes how to configure and use the Stor Next File System (SNFS) Quality of Service ( QOS) fe ature. QOS allows real-time applications to reserve some amount of bandwidth on the storage system.
Appendix D Quality of Service Guide Overview StorNext 3 .5 Install ation Guid e 143 Overview QOS is stripe-group centric; all c onfiguration and operations act on a specific stripe group. This al lows stripe groups with differing access characteristics to use different rea l-tim e settings.
Appendix D Quality of Service Guide Configuration StorNext 3 .5 Install ation Guid e 144 Non-Realtime Operation 4 Beginning with StorNext release 3.5, QOS has been enhance d to reserve bandwidth for non-realtime I/O clients.
Appendix D Quality of Service Guide Configuration StorNext 3 .5 Install ation Guid e 145 characterized as being a stripe wi dth in size. This makes the best utilization of the disks in the stri pe group and maximizes the transfer rate. Internally, non-real-time I/O is tracked by number of I/O operations per second.
Appendix D Quality of Service Guide Configuration StorNext 3 .5 Install ation Guid e 146 available. SNFS relies on the correct se tting in the configur ation file; if the storage system changes (for example , because of a new d isk array,) the user must re-qualify the I/O su bsystem to determine the amount of bandwidth availabl e.
Appendix D Quality of Service Guide Configuration StorNext 3 .5 Install ation Guid e 147 RTIO Upper Bound 4 The limit will be specified in term s of I/Os per second (parameter Rtios ) or in terms of MB/sec (parameter Rtmb ). Case is not sensitive. Note that I / Os p e r se c o n d a r e I / Os o f a ny s i z e to t h e d is k s u bs y s te m .
Appendix D Quality of Service Guide Configuration StorNext 3 .5 Install ation Guid e 148 available. For this reason, QOS always reserves some amount of I/O for non-real-time I/O. The minimum amount of non-real-tim e I/O reserved for non-real-time applications is one MB/sec.
Appendix D Quality of Service Guide Real-tim e I/O StorNext 3 .5 Install ation Guid e 149 tab of the SNFS control panel on Wind ows platforms . The default is sixty (60) seconds. This means that after sixty seconds without non-real-time I/O on a stripe group, the non-real-time token for th at stripe group is released.
Appendix D Quality of Service Guide Real-tim e I/O StorNext 3 .5 Install ation Guid e 150 Also, assume there is only one stripe group for us er data in the file system. As recommended by Quantum, there may be other stripe groups for metadata and journal that are not shown.
Appendix D Quality of Service Guide Real-tim e I/O StorNext 3 .5 Install ation Guid e 151 The client automatically issues a call to the FSM with the RT_CLEAR flag specifying the amount of real-time I/ O set on the file.

Appendix D Quality of Service Guide Callbacks StorNext 3 .5 Install ation Guid e 154 Callbacks The cornerstones of the communications between the FSM and the client are callbacks and tokens. A callback is an unsolicited message from the FSM to the client requesting that the client adjust its real-time I/O parameters.
Appendix D Quality of Service Guide Callbacks StorNext 3 .5 Install ation Guid e 155 In the above diagram, a process on cl ient A requests some amount of RTI O in St ep 1. Since this is the first re quest, the FSM issues callbacks to all connected clients (Steps 2- 5) informing them that the stripe group is now in real-time mode.
Appendix D Quality of Service Guide Callbacks StorNext 3 .5 Install ation Guid e 156 Figure 61 Callback Retraction Example In Figure 61 , Client A requests some amount of RTIO as in Figure 60 . However, assume that Client C did not respond to the init ial callback in time (step 7).
Appendix D Quality of Service Guide Callbacks StorNext 3 .5 Install ation Guid e 157 them that they will need a token to perform any non-real-time I/O. The first I/O after receiving the callback will then request a non-real-time I/O token from the FSM.
