Question
A customer complains that their SAP database now performs worse than it did before being migrated from traditional RAID storage to XIV. The database was configured using 20 x 200GB XIV LUNs presented to an AIX 6 host OS where they are concatenated and striped into six volumes for the databases and logs. No changes have been made in the transition to XIV. What if anything can be done to improve performance?
Options
- Athe SAP volumes should be put into a QoS Performance Class
- Badd Fibre Channel adapters to the host and balance volumes across the adapters
- Cimplement static load balancing and increase the queue depth of the host adapters
- Dthe databases should be reorganized into larger volumes on the XIV and not striped within the OS
