Component identification
Controller components
For cabling configuration and troubleshooting purposes, connector names are silk-screened on the controller.
For LED locations and status, see "Controller LEDs (on page 5)."

Controller LEDs
Immediately after you power up the server, the controller runtime LEDs illuminate briefly in a predetermined
pattern as part of the POST sequence. At all other times during server operation, the illumination pattern of
the runtime LEDs indicates the status of the controller.
Component identification 5
For this controller, the LEDs are typically used for debugging purposes and are not visible inside the server.

FBWC module LEDs
The FBWC module has three single-color LEDs (one amber and two green). The LEDs are duplicated on the
reverse side of the cache module to facilitate status viewing.

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

Older, and other, documentation may use SI prefixes for binary values.
Actual available memory capacity and actual formatted storage capacity for devices are less than specified
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.

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.
For more information, see the HP Smart Storage Administrator User Guide on the HP website
(http://www.hp.com/go/smartstorage/docs).
HP Secure Encryption
HP Secure Encryption is a controller-based, enterprise-class data encryption solution that protects data at rest
on any bulk storage HDDs and SSDs attached to an HP Smart Array P731m Controller. The solution is
compatible with HP key manager products and can operate with or without the presence of a key manager
in the environment, depending on individual customer settings.
HP Secure Encryption provides encryption for data at rest as an important component for complying with
data privacy requirements found in government regulations like HIPAA and Sarbanes-Oxley. HP Secure
Encryption secures any data deemed sensitive and requiring extra levels of protection through the
application of XTS-AES 256-bit data encryption. Many companies under government regulations require that
sensitive privacy data must be secured and uncompromised using NIST-approved algorithms and
methodologies for key management. As a result, HP has applied for FIPS-140-2 Level 2 validation for HP
Smart Array P731m Controller. For more information, see the Implementation Guidance for FIPS PUB 140-2
