How can your customer finish migrating the scripts after symacl is enabled?
Your customer has security and management concerns with SRDF and Timefinder scripts that are
currently running on many production hosts. Symacl will be used to reduce or limit storage
management controls to two centralized management servers. How can your customer finish
migrating the scripts after symacl is enabled?

What is the best practice HBA to FA mapping to ensure the required performance of the data warehouse?
A new data warehouse will be hosted on an existing 4-engine VMAX array. The database server
has 4 HBAs connected at 8Gb/s. Due to limited SAN switch ports only port 0 on each VMAX FA is
connected – also at 8Gb/s.
The workload is expected to require at least 1700MB/s of reads @ 128KB I/O size. It must
maintain performance in case of any major component failure in the host, switch or array. Assume
that the existing workload on the VMAX does not exceed 350MB/s per port. Also assume that the
ports can sustain up to 500MB/s without exceeding 70% utilization.
What is the best practice HBA to FA mapping to ensure the required performance of the data
warehouse?

Which metrics in Performance Manager would be useful in diagnosing the performance issue?
A data warehouse team is reporting poor performance on their batch reports. The database runs
on a Solaris host connected to a DMX-4 array with Fibre Channel drives sized to support a
sequential read workload. Which metrics in Performance Manager would be useful in diagnosing
the performance issue?
Which recommendation helps minimize this performance impact?
A customer requested a point-in-time replica of their Oracle database. You have architected a
TimeFinder/Clone environment to meet the customer’s requirements. However, the customer
immediately notices that queries against the production database are noticeably slower than
normal. Which recommendation helps minimize this performance impact?
