Chapter 2: About Your HostRAID Controller l 15

HostRAID Controller Features

Port multiplier support— You can connect one SATA drive enclosure with a port multiplier to 1225SA HostRAID controller.

Note: To find out the version of the port multiplier, refer to the drive enclosure documentation.

Adaptec supports SiI3726 with one 3 Gbps SATA II host interface and five SATA device ports. We support only 3Gbps NCQ enabled drives.

Note: NetWare does not support drive enclosures with port multipliers but supports eSATA drives.

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 50 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 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.
