AGENDA
• HPE 3PAR StoreServ architecture fundamentals
• HPE 3PAR Flash optimizations
• HPE 3PAR portfolio overview
• HPE 3PAR Flash – example from practice
• HPE RMC – Next generation backup
• Unlike most traditional architectures, limited to only 2
controllers, HPE 3PAR architecture can hold up to 8
controllers (depending on the model).
• All controllers are active on all LUNs
• Such an architecture can cover wide range of customer
needs form low midrange up to high-end.
• Single architecture (from entry 8200 up to high-end 20850
model), runs the exact same HPE 3PAR Operating System
and offer a common set of enterprise data services,
MULTICONTROLLER 3PAR ARCHITECTURE
Cost-efficient usually active/passive or active/optimized …
… but dual-controller design limits scalability and
resiliency.
Cost-effective, scalable, resilient, meshed, active-active
… … and meets cloud-computing requirements for
efficiency, multi-tenancy and autonomic management.

• The HPE 3PAR StoreServ 20000 and 8000 systems
use the fifth and latest generation of the HPE 3PAR
ASIC, the HPE 3PAR Thin Express ASIC. The HPE
3PAR Thin Express ASIC is engineered and designed
for solid-state performance.
• It works in parallel with the CPU, evenly processing the
I/O workload across the node Active—Mesh scale—out
architecture, ensuring lower latency resulting in better
system bandwidth
• Thin Express ASIC offloads some compute intensive
tasks from Controller node CPU

3PAR Hybrid storage optimizations
–Adaptive Flash Cache–Leverages portion of SSD capacity as Read Cache extension
–Does not require dedicated SSD disks
–Can be simulated
–Adaptive Optimization–subLUN level tiering
–Can use up to 3 tiers
–You can schedule data movements and performance monitoring periods
–Can be simulated
Wide striping
Addressing Flash challenges – media endurance
• Equal data distribution contributes
to equalizing data writes across
available media
• With distributed sparing, no drives
are left idle (spares contribute to
wear leveling)

Addressing Flash challenges – media endurance and cost
Due to all wear level optimization technologies, all
currently available HP 3PAR StoreServ SSDs (400
GB – 3.84 TB) carry a five-year unconditional
warranty offering drive replacement due to drive
failure, media wear-out, or both
