Performance
Eight (8) 6Gb/s SAS physical links distributed across 4 external 2x ports which supports up to 4
6Gb/s SAS Switches
6Gb/s SAS (600MB/s bandwidth per physical link)
The P711m supports higher performance between the 6G SAS Switch and MDS600 by attaching 2
SAS cables from any quad of 6G SAS Switch ports to the 2 ports on the MDS600 IO module to create
an 8x wide SAS port
1G Flash Backed Write Cache
Capacity
Dependent upon attached enclosures and arrays.

Fault Tolerance RAID
Descriptions
Keeps data available and server running while a failed drive is being replaced; several fault tolerance
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.
