HP0-J67 Question #30: Real Exam Question with Answer & Explanation

The correct answer is A. HP 3PAR StoreServ 10000 with 32 host prots. To resolve I/O latency and high queue depths on aging HP EVA storage for demanding SQL clusters, an upgrade to an HP 3PAR StoreServ 10000 with a large number of host ports is recommended. This provides significantly higher performance, parallelism, and connectivity to handle the

Architecting HP Storage Solutions for Multi-site Environments

Question

A customer has multiple eight-node SQL clusters that are currently connected to three HP EVA 8400 storage systems. The customer has I/O latency problems on the servers and sees high queue depths on the EVA ports. What should you recommend to solve this problem?

Options

AHP 3PAR StoreServ 10000 with 32 host prots
BHP StoreVirtual multi-node with FC support
CHP StoreVirtual with iSCSI to eliminate queue depths
DHP EVA P6000 which has higher queue depths

Explanation

To resolve I/O latency and high queue depths on aging HP EVA storage for demanding SQL clusters, an upgrade to an HP 3PAR StoreServ 10000 with a large number of host ports is recommended. This provides significantly higher performance, parallelism, and connectivity to handle the intense I/O workload.

Common mistakes.

B. HP StoreVirtual, while scalable and supporting FC, is generally a software-defined storage solution better suited for virtualized environments and may not provide the extreme low-latency performance required for multiple demanding SQL clusters compared to a dedicated 3PAR array.
C. Switching to iSCSI with HP StoreVirtual does not inherently eliminate queue depths or guarantee lower latency; the underlying storage architecture and its ability to process I/O are the primary factors in resolving performance bottlenecks, and FC often offers lower latency than iSCSI for demanding workloads.
D. An HP EVA P6000, while a newer generation, still shares architectural similarities with the EVA 8400 and might face similar controller and port bottlenecks under heavy load; simply allowing "higher queue depths" does not solve the fundamental I/O processing issue and latency.
