Configuration: Premium Feature—Upgrading to High-Performance-Tier 183

Configuration: Premium Feature—
Upgrading to High-Performance-
Tier
The High Performance Tier premium feature on an MD3600i Series array
increases the performance of the system beyond that of a MD3600i 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
directions on the card to obtain a key file and to 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 will 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 will return to Optimal.
When the array status returns to Optimal verify that all communication
sessions have been reestablished. If any sessions are not automatically
reestablished you must reestablished the sessions manually.
When all communication sessions to the array are ready, I/O to the array can
be restarted.
