How 3PAR Architecture Scalability Works


Smallest of SMB to the Largest of Enterprises

Simak Nazari, from HP 3PAR provides an overview of unique architecture for HP 3PAR storage that allows exceptional storage scalability for  HP Customers equaled by no other competitor. the 3PAR StoreServ family is the only product set in the industry to span midrange, high-end, and all flash systems.

Simak led the efforts at 3PAR developing the storage architecture, and faced significant challenges. In addition to changes in component parts that were resulting in incredible advancements in both rotating media and solid state drives, 3PAR engineers also had to cope with. For example, smaller systems have much fewer resources in CPU and memory than multi-CPU enterprise systems, as well as differing CPU management schemes.

Many of HP competitors offer ranges of performance in latency and IOPS – requiring a reset to move to a more complex system. HP 3PAR capabilities are explained further at .
