perf tuning for vmfs3 on RAID
- by maruti
recommendations for ESX4 OS - VMFS version3:
matching: RAID-5 stripe size with VMFS block size? (64K, 128K etc)
enabled "adaptive read ahead, write-back" on PERC 6i
90% VMs on server are Windows (2008, 2003, Vista etc, SQL 2005 etc)
i have read that smaller stipes are good for writes and larger for reads. Since this is virtual env, not sure whats good.
