Hi,
I have tested the storage performance of my storage system using three
different methods:
1. Using the NFS protocol with a 10G network, on VMware ESXi, with a 4K block
size and 100% sequential read operations.
2. Using the NFS protocol with a 10G network, on Cloudstack, with a 4K block
size and 100% sequential read operations.
Mounted with these: 'vers=4.1,nconnect=16'
3. Using the FC protocol with 16G , on Cloudstack, treating the LUN accessed
via FC as a local disk, with a 4K block size and 100% sequential read
operations.
The results show : with the same storage system, the average I/O response time
is best (0.32) when using NFS with VMware ESXi. The second is FC-SAN with
Cloudstack (1.25), and the worst is NFS with Cloudstack.
Even the NFS with ESXi is better than fc-san?
I believe there may be some configurations that could improve the storage
performance when using Cloudstack. I would greatly appreciate it if anyone
could offer some advice or solutions to help me optimize the Cloudstack storage
performance.
Thank you very much for your attention.
Best regards.
Leo.
