Specifications

Memory and storage capacity conventions

Memory capacities are specified using binary prefixes:
• KiB = 2
• MiB = 2
• GiB = 2
• TiB = 2
Storage capacities are specified using SI prefixes:
• KB = 10
• MB = 10
• GB = 10
• TB = 10

values.

RAID conventions

HP uses the following naming convention for RAID levels:
• RAID 0
• RAID 10
• RAID 5
• RAID 50
• RAID 6
• RAID 60
• RAID 1 (ADM)
• RAID 10 (ADM)
RAID 50 and RAID 60 are also known in the industry as RAID 5+0 and RAID 6+0, respectively.

Controller features

Basic features

This HP Smart Array controller has the following basic features:
• Supports RAID 0, 1, 10, 1 (ADM), 10 (ADM), 5, 50, 6, and 60
• Advanced Capacity Expansion
• Mirror splitting and recombining in offline mode
• Drive Erase
• Performance optimization for video on demand
• Dual domain
• Capability for moving and deleting individual LUNs
• Split mirror backup and rollback of RAID 1, 10, 1 (ADM) and 10 (ADM) mirrors
• Heal Array
For more information, see the HP Smart Storage Administrator User Guide on the HP website (http://www.hp.com/go/smartstorage/docs).

HP SmartCache

HP SmartCache is an advanced feature that enables solid state drives to be used as caching devices for hard drive media. Data can be accessed from the solid state drive instead of hard drives. HP SmartCache provides the following features:
• Accelerates application performance
• Provides lower latency for transactions in applications
• Supports all operating systems, without the need for changes
Use the HP SSA utility to configure support for HP SmartCache. This feature requires a license key. For more information, see the HP Smart Storage Administrator User Guide on the HP website
(http://www.hp.com/go/smartstorage/docs).

HP SSD Smart Path

HP SSD Smart Path enables an optimized data path to high performance solid state drives. The optimized path bypasses the controller’s RAID processing components and sends I/O directly to the drives. For more information, see the HP website (http://h18004.www1.hp.com/products/servers/proliantstorage/software-management/smartpath/inde
x.html).
For more information on enabling or disabling HP SSD Smart Path, see the HP Smart Storage Administrator User Guide on the HP website (http://www.hp.com/go/smartstorage/docs).
