CCJ Proposal for discussion (Ver 0.10)

Following is a preliminay proposal for CCJ for starting discussion. Every number in this table is very preliminary and subject to be changed.

Preliminary assumed specification

• Tape Storage capacity : 300 TB
• Tape Driver unit : 6 (redwood) (67MB/s)
• Cache Disk (non-raid) : 12 TB (120MB/s)
• RAID perm disk size : 0.5 TB
• CPU performance: 3125 Specint95
• I/O Throughput : 400MB/s continuously, (67MB/s for tape read, 120 MB/sec for disk read, 190MB/sec for Network write to PE through LAN interface)

CCJ Hardware Configuration idea for discussion

• Plan 1a : Using High Performance SMP Data server + Multiple Fast Ethernet I/F
• Plan 1b : Using High Performance SMP Data server and Giga-bit Ethernet I/F
• Plan 2 : Using Multiple SMP Data server and Giga-bit Ethernet I/F
