3 About Your RAID Controller
This chapter provides an overview of the features of your Adaptec RAID controller.
Standard RAID Controller Features
Support for SAS disk drives, SATA/SATA II disk drives, and SATA and SAS Solid State Drives (SSDs)
Flash ROM for updates to controller rmware, BIOS, and the Adaptec RAID Conguration utility
Disk drive hot-swapping
Event logging and broadcasting, including email notication messages
Multiple options for creating and managing RAID arrays—A browser-based software application
(maxView Storage Manager), a BIOS-based utility (ARC), a command line utility (ARCCONF) (see
Managing Your Storage Space on page 65)
Native command queuing (NCQ), which lets disk drives arrange commands into the most efcient
order for optimum performance
Support for disk drive enclosures with SES2 enclosure management hardware
Support for a ash backup module (see Adding a Flash Backup Module on page 17)
Support for Adaptec maxCache
SSD read and write caching (see Modifying Cache Settings on
page 85)
Note: Adaptec maxCache is supported on Adaptec Series Q controllers only.
Power-management of disk drives in your storage space to reduce cooling and electricity costs (see
Modifying Power Management Settings on page 85)
Audible alarm
I/O statistics logging
Array-level Features
Note: Not all features are supported by all controllers. For more information, see the
maxView Storage Manager User's Guide.
Support for RAID 0, RAID 1, RAID 5, RAID 10, RAID 50, and simple volumes
Support for hybrid RAID 1 and RAID 10 arrays comprised of hard drives and Solid State Drives (SSDs)
(Adaptec Series 6 Controllers Only) 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 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
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.
(Adaptec Series 6 Controllers Only) Hot Space (RAID 5EE)—A RAID 5EE array is similar to a RAID 5
array except that it includes a distributed spare and must be built from a minimum of four disk
drives.
Dual Drive Failure Protection (RAID 6)—A RAID 6 array is similar to a RAID 5 array except that it
includes two independent sets of parity data instead of one.
Dual Drive Failure Protection (RAID 60)—A RAID 60 array is similar to a RAID 50 array except that
it includes four independent sets of parity data instead of two.
