Chapter 2: About Your HostRAID Controller
l 15
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
for more information.
●
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.
