I just removed two old SSD’s from port 0 and 1 and inserted 2 datacenter grade SSD’s com ports 10 and 11, like they suggested me to do sometime ago to gain performance.

Now I have one information to replace the disk 0 that i don’t know how to fix.

And my performance still very poor, like 30MB/s read and 60MB/s write.

I have 3 WD3000FYYZ 3TB and 3 WD1003FBYX re 1TB and now 2 Samsung 845DSATA 240Gb. Vmware Esxi 5.0 and multipath iscsi to the servers.

Anyone can help me?

Can you confirm if you have dual disk redundancy in use? If you have dual disk redundancy in use, you need 3 SSDs in order to properly use the transactional tiering.

Also, I would recommend reviewing the following articles.

I’m using single disk redundancy.

I hire a Vmware specialist to review all my network and redundancy and everything is like best practices recommend.

I can’t get more than 30MB/s read and 80MB/s read. Sometimes i get 5MB/s read!! Impossible do work.
