Premium Feature-Upgrading To High-Performance-Tier - Dell PowerVault MD3260i Administrator's Manual

Premium Feature—Upgrading To High-
Performance-Tier
The High Performance Tier premium feature on an MD Series Dense storage array increases the performance of the
system beyond that of the 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 must enable
the high-performance-tier premium feature, using the MD Storage Manager.
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 MD Storage Manager application may change from Optimal to
Unresponsive. When the restart completes, the status returns 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.
