HostRAID Controller Features

Greater than 2 TB support—You can create and manage HostRAID arrays which are bigger
●
than 2TB size. Hence,users can use the current and future high capacity hard disk drives
above 750GB.
Flash ROM for updates to controller firmware.
●
Event logging and broadcasting, including messaging for alphanumeric pagers.
●
Support for Adaptec Metadata Format (AMF) allowing the migration of simple volumes
●
and arrays to Adaptec RAID controllers.
Multiple options for creating and managing RAID arrays—A full software application
●
(Adaptec Storage Manager), a BIOS-based utility, and a command line utility. See
Managing Your Storage Space on page 49
Support for disk drive hot swapping.
●
Support for disk drive enclosures with SAF-TE enclosure management hardware.
●

Array Level Features

Support for RAID 0, 1, 10, and simple volumes with these HostRAID limitations:
●
RAID 0: support for max. six drives with SAS and max. four drives with SATA
●
RAID 10: support for max. four drives
●
RAID 1 is build with two drives always
●
The maximum number of arrays that can be created per controller is two.
The maximum number of global hot spares per controller is one.
Hot swap rebuild of fault tolerant arrays through the operating system.
●
Support for automatic failover, so arrays are automatically rebuilt when a failed disk drive
●
is replaced (applies to redundant arrays in SES2- or SAF-TE-enabled disk drive enclosures
only).
Global hot spare protecting every fault tolerant array that the drive has enough available
●
capacity to protect.
Support for migration:
●
Simple Volume to RAID 0
●
Simple Volume to RAID 1
●
(SATA-only) Native command queuing (NCQ), which lets disk drives arrange commands
●
into the most efficient order for optimum performance.
(SAS-only) Support for disk drive enclosures with SES2 enclosure management hardware.
