Comparing Universal Storage Platform V/VM and Virtual Storage Platform
Comparison of USP V/VM and VSP
The Hitachi Virtual Storage Platform includes several upgrades from the
Universal Storage Platform V/VM as well as a number of new features. these
include:
•
High scalability. The system supports configurations of 2-1/2 and 3-1/
2 inch disk drives in either a single or dual controller configuration
• Shared processors. In the Virtual Storage Platform, the processor and
interface cards are separate. this allows either or both to be configured
separately, and allows each processor to share resources across multiple
interface cards.
• Load balancing. The VSP storage system allows workloads to be better
balanced across management processor and breaks the affinity between
specific front-end and back-end ports with specific processors.
• High performance. The system uses shared high performance quad-
core processors instead of single-core. this significantly increases
system total processing speed and distributes processing across the
FEDs and BEDs as needed.
• Faster access to system control information through the use of
onboard memory on the virtual storage directors (microprocessors).
• Storage management usability improvements . The new version
includes a user-friendly, task-based GUI that reduces the number of
operations needed to complete a task and includes wizards to assist
users in new or repetitive tasks. this version of Storage Navigator also
includes context-sensitive online help.
The following tables show the main differences between the Universal
Storage Platform V/VM and the Virtual Storage Platform.
