Features
The 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-spare
activation 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 without
disrupting volume operations.
Write Journaling for data integrity:
Write Journaling is used to verify that the disks in a mirrored volume are synchronized. It
automatically synchronizes potentially inconsistent data after the unexpected loss of electrical
power.
Background initialization for quick volume setup:
Background initialization allows host I/O operations on a newly created mirrored volume without
waiting 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 volume
are 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 failed
drive. A global hot spare allows any physical drive to be designated as a hot spare for all configured
integrated volumes.
