How to tunning the performance for SVM?

AllenChang — Sun, 25 Sep 2022 23:59:10 GMT

I am be assign to make a poc for a customer

I use FAS 2750 All flash

the protocol is iSCSI

I use all the space to create a aggr and a volume and a LUN

because I just have two 10Gb SFP+,

SO I plug the two SFP+ in the same Node,

In the vSphere I create the vmkernel and connect to the two iSCSI Target IP in the Node's 10Gb's port

but the poc's result is very bad,

so I use the qos policy to set the min iops to 10000, and max iops to 50000

but the IOPS is still low

how to optimize that I can get the best performance?

1) How are you generating the IOPS?
2) Are you sure there is enough IOPS generated by the end-application? (Whether it is a database or IO generator tools such as sio_ntap, iozone, iometer, orion, vxbench)
3) What is the workload read/write ratio?

Just Customer use the same server environment to POC two vendor,

I use FAS2750, and the other vender is HPE Alletra 6010,

in the same server and the same applition environment,

Alletra 6010's IOPS is more than my FAS2750,

so it's let me troubled

hello:

Use the QoS command to check if there are any resource limitations. This link will help you troubleshoot.
