Question 204/219

A customer configured performance monitoring and alerting for their VNX storage array. Periodically they are getting alerts on write latency greater than 15 ms. The VNX is configured with a pool of SAS drives and thin LUNs supporting a database application. NAR data, for a given period which includes one of the alerts, is examined. Flash drives are installed in the VNX; however, they are not currently used.
Examining the configuration and data shows the following:
-- Host Type = Linux
-- Multi-pathing = Native
-- Failover Mode = 1
-- Data LUNs = SP A
-- Log LUNs = SP B
-- LUN Queue Length = 1.9
-- ABQL = 7.5
How can the performance issue be resolved?

A. Install and configure PowerPath on the host

B. Configure and enable FAST Cache

C. Configure ALUA on the host

D. Balance data and log LUNs across both SPs
