HP0-J73 · Question #272

A small-business customer plans to implement an HP 3PAR StoreServ 7200. What must the customer consider regarding large, unexpected data growth?

The correct answer is A. Additional controller nodes cannot be added to the HP StoreServ 7200.. The HP 3PAR StoreServ 7200 has a fixed two-node controller configuration and cannot scale out with additional controller nodes, which is a key constraint for unexpected growth.

Why each option

The HP 3PAR StoreServ 7200 has a fixed two-node controller configuration and cannot scale out with additional controller nodes, which is a key constraint for unexpected growth.

AAdditional controller nodes cannot be added to the HP StoreServ 7200.Correct

The HP 3PAR StoreServ 7200 is architected as a fixed two-controller-node system and does not support the addition of more controller nodes, unlike the StoreServ 7400 which can scale to four controller nodes. For a small business facing large, unexpected data growth, this architectural ceiling means I/O throughput and compute cannot be increased by adding controllers. Customers who anticipate needing controller-level scale-out must consider the StoreServ 7400 platform from the outset.

BThere are no HBA expansion slots in the HP StoreServ 7200.

The HP StoreServ 7200 does include HBA expansion slots, so the absence of HBA expansion is not an accurate or documented constraint for this platform.

CAdaptive Optimization suffers a performance impact with large data.

Adaptive Optimization continuously tiers data based on access patterns and is not documented to suffer a general performance impact specifically due to large data volumes.

DThe HP StoreServ 7200 configuration must have fewer than four drive chassis.

The four-drive-chassis statement does not accurately reflect a documented configuration restriction of the HP StoreServ 7200, making it an incorrect consideration.
