FIGURE 3: Typical Sequence of Installation Steps
Reliability, Availability and Serviceability
Comprehensive reliability, availability and serviceability (RAS) are assured within SANnet II 200
SCSI arrays. Proven low voltage differential (LVD) signaling across all disk and host SCSI buses
keeps data transfers reliable. Flexible support for RAID levels 0, 1, 0+1, 3, 5, 3+0 and 5+0, plus
global and dedicated spare disks provide powerful choices for protecting valuable information.
Every FRU is hot-swappable or hot-serviceable to virtually eliminate downtime, plus critical
FRUs operate in redundant pairs.
