Is there any way to get Guaranteed IOPS in DBCS apart from dense io/high io
SummaryIOPS sizing in DBCS
Hi As per Oracle documentation the iOPS provided per block volume is available at a rate of around 60 iops per Gb until a ceiling of 25,000 IOPS which is hit at 500 GB.
When running a database on IaaS I can control the number of Block volumes I use in order to maximize iops . i.e I have an asm disk size of 500GB
but is there any way to do this in DBCS. Given that a disk can grow to 32 Tb in size and a 32Tb disk also has the same iops as a 500 GB disk is ther some algorithm in DBCs which prevents iops starvation by going with a more sensible size ? I could not find any way to set this when creating a db system. And its not clear to me if the dbcs system uses a sensible size for each asm volume when for example creating a two node RAC cluster.... previously when 2TB was the largest
