Lenovo ServeRAID H1110 Product Manual

FeaturesThe ServeRAID H1110 adapter has the following features:Resynchronization with Concurrent Host I/O Operation:Host's I/O operations are not halted when the volume is re-synchronized because of a hot-spareactivation or disk replacement, thereby avoiding downtime.Online Capacity Expansion for Integrated Mirroring (RAID 1) volumes:Online Capacity Expansion (OCE) allows the capacity of a two-drive integrated mirroring volume(RAID 1) to be expanded by replacing existing physical disks with larger capacity disks withoutdisrupting volume operations.Write Journaling for data integrity:Write Journaling is used to verify that the disks in a mirrored volume are synchronized. Itautomatically synchronizes potentially inconsistent data after the unexpected loss of electricalpower.Background initialization for quick volume setup:Background initialization allows host I/O operations on a newly created mirrored volume withoutwaiting for the process of copying data from the primary disks to secondary disks to complete.Consistency Check for background data integrity:Consistency Check verifies that all data on the primary and secondary disks in a mirrored volumeare identical.Global Hot Spare support:A hot spare rebuilds data from a failed drive in an integrated volume that supports data redundancy.ServeRAID provides the ability to define a physical disk as a global hot spare to replace a faileddrive. A global hot spare allows any physical drive to be designated as a hot spare for all configuredintegrated volumes.Server supportThe ServeRAID H1110 adapter is supported in the servers that are listed in the following tables.Support for System x and dense servers with Xeon E5/E7 v4 and E3 v5 processorsTable 2.
