HPE Smart Array P741m Controller

The HPE Smart Array P741m is a PCI-Express (PCIe) 3.0 mezzanine card supporting direct attached and shared storage for the
HPE

Gb/s level bandwidth and provides enterprise level reliability, connectivity,

and storage performance for

Blade servers through its support of the latest SCSI technology and advanced RAID

capabilities. The

can support up to 227 zoned direct attached SAS or SATA drives, tape drives, and can connect to D3600,

D3700, D6000, and D6020 Disk Enclosures.

Fault Prevention

The following features offer detection of possible failures before they occur, allowing preventive action
to be
S.M.A.R.T.:

Hewlett Packard
Enterprise detects possible hard disk failure before it occurs, allowing replacement of the component
before failure occurs.
Drive Parameter Tracking monitors drive operational parameters, predicting failure and notifying the
administrator.
Dynamic Sector Repairing continually performs background surface scans on the hard disk drives during
inactive periods and automatically remaps bad sectors, ensuring d
Smart Array Cache Tracking monitors integrity of controller cache, allowing pre-failure preventative
maintenance.

Fault Recovery

Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure:
Recovery ROM: This feature protects the user from a firmware image corruption by storing a redundant
copy of the firmware image. If the active firmware image becomes corrupt, the controller will use the
redundant firmware image and continue operating.
On-Line Spares: There is no limit to the number of spare drives that can be installed prior to drive failure.
If a failure occurs, recovery begins with an On
DRAM ECC detects and corrects data bit errors.

HPE SmartCache

The HPE SmartCache feature is a controller-based read and write caching solution in a DAS environment
that caches the most frequently accessed data ("hot" data) onto lower latency SSDs to dynamically
accelerate application workloads. The HPE SmartCache architecture is flexible and supports any HPE
ProLiant Gen9 supported HDD for bulk storage and any HPE ProLiant Gen9 supported SSD as an
accelerator. HPE SmartCache is deployed and managed using the HPE Smart Storage Administrator
(HPE SSA).

HPE Secure Encryption

HPE Secure Encryption is a Smart Array controller-based data encryption solution for ProLiant Gen9
servers that protects sensitive, mission critical data. This is an enterprise-class encryption solution for
data at rest on any bulk storage attached to the

including data on the cache

memory of the controller.

requiring encryption
enablement (see Related Options for more information on the license).
The solution is available for both local and remote key management mode deployments. Local Key
Management Mode is focused on single server deployment where there is one Master key per controller
that is managed by the user. Remote Key Management Mode is for enterprise wide deployments from
just a few servers to thousands of servers.

FIPS 140

FIPS provides a security assurance level validation for cryptographic modules. HPE Smart Array P741m
controller has completed FIPS 140

The validation for this

controller has

moved to the Historical List. HPE is actively engaged in activities to return this

controllers to the Validate

The National Institute of Standards and Technology (NIST)
issued the FIPS 140-2 requirements and standards for cryptography modules that include both
hardware and software components.

HPE SSD Smart Path

The HPE SSD Smart Path feature included in the Smart Array software stack improves Solid State Disk
(SSD) read performance. With up to 4x better SSD read performance, HPE SSD Smart Path chooses the
optimum path to the SSD and accelerates reads for all RAID levels and RAID 0 writes. HPE SSD Smart
