I joined VMware in 2012 as a Senior PSO Consultant and now work in the GCoE as Senior Solution Architect, Data Platforms. My background, I have been a Production Oracle DBA / Architect for the last 19 odd years for many Fortune 100 companies (having started with Oracle version 6 in my school days, long long time ago). “Software defined storage” and Quality of Service (QoS) through policy based management solutions will solve this over time. The results of this theoretical analysis amply demonstrates the fact that application owners, DBA’s, VMware administrators and storage administrators would have to work hand in hand in order to setup a well-tuned Oracle database on vSphere especially in in a non-VVol or VSAN world. What this article tries to endeavor is to illustrate, with a simple example, the fallacy in presuming that queue tuning only needs to be done at the Application level and that it’s okay to ignore storage physical limitations. Much has been written about Virtualization & Storage queues, excellent blog articles by Duncan Epping, Cormac Hogan and Chad Sakac go through in depth about the various queues. Imagine what would have happened if there were no queues?ĭisorder, chaos, anarchy: now that’s fun! – DAVID J. ![]() ![]() Queues are often misrepresented as the very “bane of our existence” and yet queues restore some order of semblance to our chaotic life. Proper queues sizing is a key element in ensuring current database workloads can be sustained and all SLA’s are met without any processing disruption.
