You are working with a customer to design a VNX for Block solution for their SQL database. They currently have a CX4-480. In the past they have co-located their database and log files. In the new VNX design, the database will be placed in a FAST VP enabled pool. The transaction logs will be placed on a traditional RAID Group. Your customer needs help determining the number of spindles they need to satisfy the needs of their transaction logs. You know the following:

Transaction period: 8 hours (business day)

Throughput during transaction period: 240 GB

How many RAID 1/0 15K spindles will the transaction log volume require?
