I have an SAP ERP EHP6 instance running on Windows 2008 R2 and Sybase ASE 15.7.0.101 This is a Production system - and users have reported long response times, further looking into the installed architecture, we have noticed that disk reads have been very high always at 99% to 100%, therefore we have also noticed, that our Sap implementation partner has installed the Database and the transaction logs both on the same Partition(data store), we wish to move the transaction logs to another partition.
By doing this segregation, we intend to address the excessive disk reads that are happening on one single partition.
How can this be achieved ?
Our current production system is installed and running on windows 2008 R2 in a windows - fail over cluster environment.
RDM luns are presented directly from Storage as partition disks to the clustered nodes.
Will need to understand, in this sort of environment what is the best practice that needs to be followed.
and how the transaction logs can be moved to another partition ?
