HP D5970A Installation and configuration of the HP NetRAID, NetRAID-1 and NetR - Page 15

Chapter 1 Introduction New Features of HP NetRAID Series Adapters New features of HP NetRAID Series adapters include: • Enhanced Array Spanning • Enhanced Configuration Replication • Support for Clustering • I2O Support (HP NetRAID-3Si adapters only) Enhanced Array Spanning The HP NetRAID Series adapters allow up to four arrays to be spanned together as one logical drive, rather than the two-array maximum supported previously. For example, HP NetRAID Series adapters can support a RAID 10 logical drive with up to eight physical disks. HP NetRAID and HP NetRAID-3Si adapters using all three channels can group up to 18 to 24 physical disks in a RAID 30 or RAID 50 logical drive depending on the HP system and enclosure used. Enhanced Configuration Replication in HP NetRAID Assistant Utility When you save a configuration using the HP NetRAID Assistant utility, HP NetRAID Series adapters now save both logical drive and adapter configuration settings. (Adapter settings include such parameters as the Rebuild Rate, Power Fail Safeguard, and Auto Rebuild.) NOTE The HP NetRAID Config and HP NetRAID Express Tools utilities save logical drive settings only and do not save adapter settings. Support for Clustering The HP NetRAID Series adapters can be used with HP NetServer clusters. HP NetServer clusters provide reliable, increased-availability solutions for applications where unplanned downtime is unacceptable. In all HP NetServer configurations, both cluster nodes share the drives located in the external shared storage cabinets using an HP NetRAID Series adapter located in each HP NetServer node.
