Standard Features
Page 4
configurations are supported including:
• RAID 6 (Advanced Data Guarding): Supported with a minimum of 4 drives. This allocates two
sets of parity data across drives. This level of fault tolerance can withstand a double drive
failure without downtime or data loss.
• RAID 60: Supported with a minimum of 8 drives. This volume is composed of two or more
RAID 6 sub-volumes (parity groups) where data is striped across each parity group as if it
were a single physical drive. Each RAID 6 parity group can sustain up to two drive failures
without incurring data loss.
• RAID 5
(Distributed Data Guarding): Supported with a minimum of 3 drives. This allocates one
set of parity data across drives. This level of fault tolerance can withstand a single drive failure
without downtime or data loss.
• RAID 50: Supported with a minimum of 6 drives. This volume is composed of two or more
RAID 5 sub-volumes (parity groups) where data is striped across each parity group as if it
were a single physical drive. Each RAID 5 parity group can sustain a single drive failure
without
incurring data loss.
• RAID 1 & 10 (Drive Mirroring): Supported with a minimum of 2 drives. This allocates half of
the drive array to the data and the other half to the mirrored data, providing two copies of the
data.
• RAID 1 ADM & 10 ADM (Advanced Data Mirroring): Supported with a minimum of 3 drives.
RAID 1 ADM creates redundant copies of the data using 3 drives. RAID 10 ADM stripes data
across two or more sets of RAID 1 ADM volumes. This level of fault tolerance can withstand a
double drive failure within a RAID 1 ADM volume without downtime or data loss.
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-Line Spare and data is
reconstructed automatically.
• DRAM ECC detects and corrects data bit errors
Ease of Use
Consistency and upgradeability on most current shipping Smart Array products make them unique in
the industry:
• GUI based configuration, management and diagnostic software tools with the HPE Smart
Storage Administrator
• Common data format between generations of products
• Data migration between servers and external Modular Smart Array enclosures and Disk
Enclosures
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
Path requires updated firmware, drivers, and configuration utility available at:
http://www.hp.com/go/hpssa
. HPE SSD Smart Path is ideal for read intensive workloads and is
included as a base feature on
HPE Smart Array P-series controllers. The following operating systems
are supported by the
HPE SSD Smart Path feature:" Microsoft Windows Server 2008
• Microsoft Windows Server 2008 R2
