1)Given a block size of 4096 bytes and a record size of 400 bytes. How many records can be stored per block (blocking factor) using spanned configuration?
2)Given a block size of 4096 bytes and a record size of 400 bytes. What is the utilization (percentage) for the unspanned configuration?
3) The database stores an employee table consisting of 500,000 records each of which is 400 bytes long. A SSD has storage capacity of 1 TB, read bandwidth of 1 GB/sec., and a block size of 4096 bytes.
Assume the data is stored sequentially. What is the time (in seconds) to read all records in the unspanned configuration?
