1. Connectivity – Make sure bottlenecks to do not exist within your SAN fabric. Often we find clients who have 4Gbps disk systems connecting to 2Gbps SAN switches or HBAs. A smart idea is to quickly review all pieces of your SAN fabric to identify potential bottlenecks.
  2. Drive Count – System performance is often easily fixed by adding additional disk drives to the storage configuration. The reason this fix works is that by spreading out the workload, you gain the advantage of having more drives/arms/spindles accessing and retrieving data, and feeding that data to the storage controller.
  3. Drive Size – By using smaller faster drives for high performance environments such as Oracle, you avoid disk drive contention. Contention can manifest itself when too much data is placed on larger drives. An example would be trying to place 2.5TB of data on 10x 300GB Drives.
  4. Drive Type – SATA drives are an excellent format for archive or low I/O applications such as file servers or imaging, but become less ideal for larger VMWare, Oracle or Exchange Environments. Make sure you invest in the right technology according to application and workload
  5. Controller Segregation – As storage requirements continue to grow, small storage shops can eventually morph into large storage shops. If multiple high performance applications are placed on a single modular array it may overwhelm the system. Consider a second array or a tiered architecture should your array have a high combination of performance-oriented applications
  6. RAID Level – Raid 10, Raid 1, Raid 6, RAID-DP, Raid5 and other parity combinations all have their strength and limitations. Do your research to make sure the RAID configuration you are considering will support and maintain application performance for the long term.
