Configuration: Premium Feature—
Upgrading to High-Performance-
Tier
The High Performance Tier premium feature on a MD3200 Series array
increases the performance of the system beyond that of a MD3200 Series
array operating at the standard performance level.
If this feature is ordered, a Premium Feature Activation card is placed in the
box with the storage array. After reading the information below, follow the
instructions on the card to obtain a key file and enable the feature.
CAUTION: Loss of data access – The storage array automatically restarts when
the High-Performance-Tier feature is enabled or disabled. During the restart, data
is unavailable. Data availability is restored when the array restarts.
To upgrade from a standard-performance-tier storage array to a high-
performance-tier storage array, you enable the high-performance-tier
premium feature, using the Dell PowerVault Modular Disk Storage
Management (MDSM) software.
When the high performance tier feature is enabled or disabled the array
restarts. During this time data access and management access to the
controller is be temporarily lost.
It is recommended that all I/O to the array be stopped before this feature is
enabled or disabled.
While the array is restarting, the state of the array in the MDSM application
may change from Optimal to Unresponsive. When the restart completes the
status returns to Optimal.
When the array status returns to Optimal, I/O to the array can be restarted.
