Physics Requirement-3Physics Analysis

• Physics analysis will be performed for the ?DST many times.

  • Disk I/O bandwidth is important.

• We assume 1/5 of the ?DST is required to be resident in DISK.

• Assuming the access to the whole ?DST on DISK can be done 5 times in a day

  • Required disk read bandwidth is 520MB/s.

Storage(?DST) 45 TB/y

DISK Storage(?DST) 9 TB

DISK I/O 520 MB/s

CPU(requirement) 1000 SPECint95
