New Business Requirements create new Storage Challenges
Performance
Different applications have very different workloads,
Especially when virtualized the sum of these demands
becomes unpredictable and is always mixed
Scalability & Agility
Data grows rapidly and
at unpredictable rates
Storage needs to be able to adapt to
changes quickly and in any direction
Availability

Requirements
from SMB to
Enterprise

High availability is a requirement for
customers of any size
24x7 business doesn’t allow backup or

Efficiency
Storage capacity costs dilute savings for
server virtualization
Unpredictability drives overprovisioning

• 3PAR keeps a bitmap for each page and writes only the dirty part of
the Cache page is written to Flash
8KB
• For a 4KB r/w IO, only 4KB are transferred between Cache and Flash
4KB
• sub-16KB reads and writes IOs do sub-16KB transfers
• Reduces latency and backend load by avoiding

Yes – Read data from backend and XOR with new

If XOR result = 0  just update metadata
If XOR result ≠ 0  write new host data to
