Chapter 3: About Your RAID Controller 18

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 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) (see Managing Your Storage Space on page 79)

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 19)

Support for a zero maintenance cache protection module (see page 19)

Support for Adaptec maxCacheTM SSD caching (see page 109)

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 page 106)

Audible alarm

I/O statistics logging

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 hybrid RAID 1 and RAID 10 arrays comprised of hard drives and Solid State Drives (SSDs)

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
