Adaptec Storage Manager supports an advanced read caching technology called maxCache. Adaptec maxCache uses the Solid State Drives (SSDs) in your system as a fast read cache pool to improve performance in read-intensive applications.
With maxCache Read Caching enabled, the system analyzes IO traffic patterns and copies frequently read “hot” data to the SSD cache pool—the maxCache pool.
You can configure maxCache SSD caching only if you have one or more compatible Solid State Drives installed on the RAID controllers in your system. See www.adaptec.com/compatibility for a list of maxCache-compatible Solid State Drives.
Note! maxCache Read Caching is supported by Adaptec Series Q controllers only.
Adaptec Storage Manager assigns all compatible SSDs to the maxCache pool, by default. Use the following procedures to add or remove SSDs, to configure the maxCache flush and fetch rate, to enable maxCache read caching for a logical device, and to clear the maxCache pool.
To check the status of the SSDs in the maxCache pool, including wear-level and longevity indicators, see Maintaining Solid State Drives. To check maxCache statistics for a logical device, see Logging Statistics for Remote Analysis.
To configure the maxCache pool:
In the Logical Devices View, click the Configure maxCache cache pool button.
The Configure maxCache Cache Pool window opens.
Select one or more SSDs in the Available SSDs list, then click SSD >. (Show Me!)
The SSD is added to the maxCache pool and the icon changes to indicate that it’s part of the cache.
To remove a SSD from the cache, select one or more SSDs from the maxCache Pool list, then click < Cache.
Select the maxCache flush and fetch rate from the drop-down list: Low, Medium, High. (The default is Medium.)
Click Apply.
The Configure maxCache Cache Pool window closes and the cache configuration is saved.
To enable/disable maxCache Read Caching for a logical device:
In the Logical Devices View, select a logical device.
In the menu bar, select Actions, click Configure maxCache, then select Enable/Disable MaxCache Read Caching,as needed.
In the Enterprise View, select a controller.
In the menu bar, select Actions, then click Clear MaxCache.
The maxCache pool is cleared.
