Chapter 3: About Your RAID Controller
●
16
Standard RAID Controller Features
●
Support for SAS, SATA, and SATA II disk drives
●
Flash ROM for updates to controller firmware, BIOS, and the Adaptec RAID
Configuration utility
●
Disk drive hot-swapping
●
Event logging and broadcasting including email and SNMP messages
●
Multiple options for creating and managing RAID arrays—A full software application
(Adaptec Storage Manager), a BIOS-based utility (ACU), a command line utility
(ARCCONF), and a DOS utility (see
Managing Your Storage Space
on page 53
)
●
Native command queuing (NCQ), which lets disk drives arrange commands into the most
efficient order for optimum performance
●
Support for disk drive enclosures with SES2 enclosure management hardware
●
Support for a battery backup module (see
page 17
)
●
Audible alarm
●
Power-management of disk drives in your storage space to reduce cooling and electricity
costs (see
page 79
)
●
I/O statistics logging and automatic forwarding for remote analysis (“call home”)
Array-level Features
Note:
Not all features are supported by all controllers. For more information, refer to the Adaptec
Storage Manager User’s Guide or online Help.
●
Support for RAID 0, RAID 1, RAID 5, RAID 10, RAID 50, simple volumes, and spanned
volumes
●
Support for JBOD disks (appear as a physical disk drives to the operating system; not
redundant)
●
Support for hot spares (global and dedicated)
●
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
)
●
Optimized disk utilization, which ensures that the full capacity of all disk drives can be
used, even if the disk drives vary in size
●
Online capacity expansion, so you can increase the capacity of an array without recreating it
●
Support for array migration from one RAID level to another
Advanced Data Protection Suite
Note:
The following features are supported by Adaptec 5-Series controllers only.
●
Copyback Hot Spare
—You can use this feature to move data from a hot spare back to its
original location after a failed disk drive is replaced.
●
Striped Mirror (RAID 1E)
—A RAID 1 Enhanced array is similar to a RAID 1 array except
that data is both mirrored
and
striped, and more disk drives can be included.
