HPE 3PAR --- AFC - Adaptive Flash Cache configuration

[Carlos_Oliveira]

Hi ALL,

I have a customer  here in the region who has a 3PAR8200 with SSD and SAS FC disks, he reports slow reading on the FC disks... he would like to configure an SSD space to do the AFC on the SAS FC! It's possible ? What would be the procedure? Is there a way to do this via creating a VV SSD as AFC? What would be the minimum size in this case when creating the AFC on SSDs?

Thank you in advance... regards,

Carlos Oliveira.

Hi Carlos Oliveira,

You can configure the Adaptive Flash Cache on your HPE 3PAR 8200 by using the space from SSD.

Here is the procedure.
1. Login to the HPE SSMC.
2. Go to the main menu.
3. Click on “Show all”.
4. Select “Adaptive Flash Cache” under “Optimization”.
5. You will see the list of systems. Select the system to configure the Adaptive flash cache.
6. Go to the “Actions” menu at the top right corner.
7. Click on “Edit”.
8. On the Edit window, select the “Mode” from the dropdown. In this instance, we have selected “Simulation”.

Note: Standard mode requires a minimum amount of available SSD space (64 GiB per node pair) and a minimum number of SSDs per node depending on the system model.
Simulation mode does not require available SSD space and provides the opportunity to assess how adaptive flash cache would perform in standard mode.

9. Select the “Size” from the drop-down.
10. You may select the Adaptive Flash Cache state from the dropdown. By default, it is disabled. Here we are selecting “Enable All Volumes”.

Note: If you select the option “Enabled Volume Sets”, click on “Add Volume Sets” and you may select one or more existing volumes sets from the system.
11. Click on “Ok” after making the required selections.
