5220 Appliances - Buffer Tuning & Throughput
Does anyone have any experience of tuning throughput on a 5220 Appliance ?
I note that the data buffers are set to 262144 (standard setting) and there are 30 of them. Are you finding that these require tuning to achieve maximum throughput or are you simply leaving them set to default ?
I have a Virtual Master server at 7504 and a single 5220 acting as a media server attached to both SAN (for VMware integration) and a tape library containing 2 x LTO5 drives. I am backing up VMware machines using the VMWARE policy type (SAN transport), physical machines using agents over the network and CIFS data using the NDMP policy type.
In addition, I am using AIR to replicate to a similar configuration for DR.
Before I start tuning I thought I would put this out there to discover what everyone else may have already found as best practice......
