Size of Read Buffers and Number of Read Buffers
I try to increase read performance from storage subsystem (used for vSphere) during backup, now i use default values and perform SAN based backup.
According to technote http://www.symantec.com/business/support/index?page=content&id=TECH185691, to improve performance i need to change parameters "Size of Read Buffers" and "Number of Read Buffers", but what should i specify ? For example maximum block size which supported on Storage Subsystem is 512K, Block size of vmfs 1M? Block of deduplication pool 64K. With default parameters i see from source storage logs block 512K and 110 IOPS.
I use Media Server 2010 R3 SP2 x64 Win2008R2.
