CCJ Proposal for discussion Plan 2
CCJ Hardware Configuration idea for discussion Plan-2
- DataIn: Tape/disk to server
- 6 tape drives to server = 67.5 Mbps (for data mining)
- Cache disk to server = 120 Mbps (for physics analysis)
- Totally 190 MB/s from tape and disk
- DataFeed: Network IO to PE node
- Data server to HUB : Giga-bit Ether x 4
- Peak bandwidth 4 Gbps/1.6Gbps = 40%
- Feature of this system
- Requires very high performance SMP data server
- Giga-bit Ehtenet interface will be available in 1998
- I/O intensive job can be also done using the CPU's of the SMP server instead of using massive PE
- In case of trouble of massive PE , all system still works correctly using the CPU's of SMP data server
