• Evaluate the current TCO of storage: – Hardware and software – Network resources – Utilization of existing capacity – Management – Downtime (unplanned) – Downtime (backup and maintenance)
• Design the SAN solution accordingly Functionality TCO
Audit current storage costs, including hardware and software, management, downtime, and backup:
What are the current hardware and software maintenance costs, including both storage devices and servers? What is the cost of the network bandwidth consumed by storage traffic? How much disk space is currently not utilized due to inflexible allocation? How much time is spent managing storage (and what is actually accomplished)? How much downtime is incurred due to system failures? How much downtime is incurred due to backup and planned maintenance?
Design the SAN solution to address specific costs.
