Pagination
If a search of ioMemory storage devices results in multiple pages, use the controls at the bottom of the list to

All ioMemory
The All ioMemory screen provides detailed information about the ioMemory devices, directCache cache
instances, machines that host ioMemory devices, and clusters of which those host machines might be a part.
You are able to perform maintenance and management tasks on several devices at once.
Low level format
Your IO Accelerator comes pre-formatted so it is not usually necessary to use this option. However, you might
use it in the following circumstances:
• You must reformat the drive to change its logical size to enhance write performance.
• You are instructed to do so by HP Customer Support.
The IO Accelerator Management Tool performs a low-level format that is different from a format performed
by an operating system using standard disk management utilities. You do not need to perform an IO
Accelerator Management Tool low-level format to create an operating system-specific volume on the device.
CAUTION: Formatting an IO Accelerator destroys any data still on the device. If you have not
backed up data to another device, choose Cancel to abort the format.
To format an IO Accelerator:
1. Select one or more IO Accelerators from the Device Tree.
2. Click Format to display the Low-Level Format window.
3. Select which type of format you want to perform:
o Factory Capacity
o Maximum Capacity—Creates the maximum possible capacity for user data on the device. This
format is standard on a new IO Accelerator.
o Improved Performance—Formats the device for increased write performance at the cost of
approximately 30% capacity.
