We are using FAS 8020. One of our application requires 40 MB/s throughput on a virtual machine. Ontap version is 8.3 cluster mode
We run vertica utility on VM and found only 25 to 35 mb/s throughput. We are using 10k rpm SAS disk and total 22 data disks dedicated aggregate for this task.
We had tuned our Linux VM for better performance like an eager thick disk. Only one VM on single esxi server etc.
We have also provided FC RDM lun but expected performance not achieved.
Please help us to guide how we can achieve this.
