Overview Hard disk drives (HDDs) can be a bottleneck for storage-intensive operations due to the long access times inherent in their design. The lower latency and higher bandwidth of solid-state drives (SSDs) make them the preferred storage medium when high performance is a priority, although they incur a higher cost per bit than HDDs. With both storage technologies exhibiting advantages and drawbacks, using hybrid storage can be the optimum solution.

2. The Enable Acceleration dialog box appears. Select Disk on port1 (298 GB) (system) item, and then click the OK button if you choose to enable Intel Smart Response Technology. 3. The Acceleration View section confirms that the acceleration feature has been enabled.
PAGE 5
How to disable Intel Smart Response Technology To disable Intel Smart Response Technology, use the following procedure. 1. In the Acceleration tab under the Acceleration Configuration section, click the Disable acceleration link. 2. The Disable Acceleration confirmation box appears. Click the Yes button to disable Intel Smart Response Technology.
PAGE 6
3. 6 The Acceleration Configuration section confirms that the acceleration feature has been disabled. NOTE: The cache volume will not be available for other uses unless the device is “Reset to available”. Refer to the How to reset the cache device section for more details.
PAGE 7
How to re-enable Intel Smart Response Technology To re-enable Intel Smart Response Technology after it has been disabled, use the following procedure. 1. In the Acceleration Configuration section, click the Select device link. 2. The Accelerate Disk or Volume dialog box appears. Select the Disk on port1 (298 GB) (system) item, and then click the OK button if you choose to re-enable Intel Smart Response Technology.

3. The Acceleration Configuration section confirms that the selected disk is now accelerated. How to change the Intel Smart Response Technology mode To change the Intel Smart Response Technology mode, use the following procedure. 1. 8 To change the acceleration mode, click the Change mode link.
PAGE 9
2. The Enable Enhanced Mode confirmation box appears. Click the Yes button if you choose to change the acceleration mode to the Enhanced option. 3. The Acceleration Configuration section confirms that the Enhanced mode is enabled.
PAGE 10
4. The Enable Maximized Mode confirmation box appears with a WARNING. Click the Yes button if you choose to change the acceleration mode to the Maximized option in spite of the warning. Click the No button to heed the warning and make no changes. How to reset the cache device Resetting the cache device to “available” allows the device to be visible to the OS. To reset the cache device using the Accelerate tab, use the following procedure.
PAGE 11
3. After the process is completed, a cache device will be shown and marked as Unallocated.
PAGE 12
Once a cache device has been set to being available, a restart of the computer management/storage/disk management utility will result in the OS displaying a popup message (shown below) allowing you to partition the drive if it is to be used as a separate drive.
PAGE 13
Configuring Intel SRT using the Option ROM The option to configure the Intel Smart Response Technology using the option ROM (OROM) user interface (UI) is intended for service purposes only. This option is available only when an SSD/mSATA drive is used as cache. The option to display the OROM prompt during POST is disabled by default. The OROM prompt is displayed only in the following cases.
PAGE 14
Replacing the cache device The cache device can be replaced using one of the following procedures. Replacing the cache device with another cache device pre-configured as RAID (cache) or storage mode To replace the cache device with another cache device that is pre-configured as RAID (cache) or storage mode, follow these steps: 1. Disable the Intel Smart Response Technology acceleration feature using the Accelerate tab, or the OROM UI.

A: The OROM prompts the user to configure the Enhanced—Write through, or the Maximized—Write back mode. Q: Does Intel Smart Response Technology diagnose, display, or report any errors when the user executes the Enhanced—Write through, or the Maximized—Write back mode? If yes, which reports are displayed? A: Intel Smart Response Technology checks and displays information on the Acceleration modes without notifying the user of the status of the modes. No reports are provided.
