As Customer is asking if we can define LUN level QOS on a G1000. I can't seem to find how.
Please tell me that I'm wrong, along with a link to some howto do it.
QoS is available via Server Priority Manager and offers WWN and Port level controls. As such it does not resolve control to individual Luns - unless you have the candidate Lun as the only visible volume to a WWN.
The controls offer a minimum availability of IOPS or MB/sec resource (Prioritised Threshold), or a maximum availability of IOPS or MB/sec resource (Non-Prioritised Upper limit)
The G1000 has so few throughput and processing constraints that the Port level option is probably not fully necessary. The WWN scheme is probably the main useful one where multiple servers fan-in to the same Port and can interfere with each other. The use-case example is a transaction server on the same Port as a data-warehouse server.
The scheme works best in my opinion where there are only a few WWN elements being controlled on any single Port, Prioritised or Non-Prioritised.
Nice to ear from you Glenn.
I agree with you on the point of the G1000 won't need much such a feature by nature but unfortunately, Customers might see the lack of a LUN level QOS feature as a down point instead of looking at the overwhelming power of the whole system, specially when comparing a feature matrix table with others.
JS, As I work through all the enhancements to SVOS7 I see that iSCSI LDEV-WWN control is now present in SVOS7. The values must be set lower than for the port (makes sense). So that at least allows one checkbox to be completed.
