RAID 7.

Udgivet d. 16 Nov. 2001 af: Bo Krüger Hansen

All I/O transfers are asynchronous, independently controlled and cached including host interface transfers
All reads and write are centrally cached via the high speed x-bus
Dedicated parity drive can be on any channel
Fully implemented process oriented real time operating system resident on embedded array control microprocessor
Embedded real time operating system controlled communications channel
Open system uses standard SCSI drives, standard PC buses, motherboards and memory SIMMs
High speed internal cache data transfer bus (X-bus)
Parity generation integrated into cache
Multiple attached drive devices can be declared hot standbys
Manageability: SNMP agent allows for remote monitoring and management

Overall write performance is 25% to 90% better than single spindle performance and 1.5 to 6 times better than other array levels
Host interfaces are scalable for connectivity or increased host transfer bandwidth
Small reads in multi user environment have very high cache hit rate resulting in near zero access times
Write performance improves with an increase in the number of drives in the array
Access times decrease with each increase in the number of actuators in the array
No extra data transfers required for parity manipulation
